[Gitea](https://gitea.io/en-us/) is a community managed lightweight code hosting solution written in Go.
It is published under the MIT license.

## Introduction

This helm chart has taken some inspiration from [jfelten's helm chart](https://github.com/jfelten/gitea-helm-chart).
Yet it takes a completely different approach in providing a database and cache with dependencies.
Additionally, this chart allows to provide LDAP and admin user configuration with values.

## Update and versioning policy

The Gitea helm chart versioning does not follow Gitea's versioning.
The latest chart version can be looked up in [https://dl.gitea.com/charts](https://dl.gitea.com/charts) or in the [repository releases](https://gitea.com/gitea/helm-chart/releases).

The chart aims to follow Gitea's releases closely.
There might be times when the chart is behind the latest Gitea release.
This might be caused by different reasons, most often due to time constraints of the maintainers (remember, all work here is done voluntarily in the spare time of people).
If you're eager to use the latest Gitea version earlier than this chart catches up, then change the tag in `values.yaml` to the latest Gitea version.
Note that besides the exact Gitea version one can also use the `:1` tag to automatically follow the latest Gitea version.
This should be combined with `image.pullPolicy: "Always"`.
Important: Using the `:1` will also automatically jump to new minor release (e.g. from 1.13 to 1.14) which may eventually cause incompatibilities if major/breaking changes happened between these versions.
This is due to Gitea not strictly following [semantic versioning](https://semver.org/#summary) as breaking changes do not increase the major version.
I.e., "minor" version bumps are considered "major".
Yet most often no issues will be encountered and the chart maintainers aim to communicate early/upfront if this would be the case.

## Dependencies

Gitea can be run with an external database and cache.
This chart provides those dependencies, which can be enabled, or disabled via configuration.

Dependencies:

- PostgreSQL HA ([configuration](#postgresql))
- Redis Cluster ([configuration](#cache))

## Installing

```sh
helm repo add gitea-charts https://dl.gitea.io/charts/
helm repo update
helm install gitea gitea-charts/gitea
```

When upgrading, please refer to the [Upgrading](#upgrading) section at the bottom of this document for major and breaking changes.

## High Availability

⚠️ **EXPERIMENTAL** ⚠️

Since version 9.0.0 this chart has experimental support for running Gitea and it's dependencies in a HA setup.
The setup is still experimental and care must be taken for production use as Gitea core is not yet officially HA-ready.

Deploying a HA-ready Gitea instance requires some effort including using HA-ready dependencies.
See the [HA Setup](docs/ha-setup.md) document for more details.

## Configuration

Gitea offers lots of configuration options.
This is fully described in the [Gitea Cheat Sheet](https://docs.gitea.io/en-us/config-cheat-sheet/).

```yaml
gitea:
  config:
    APP_NAME: "Gitea: With a cup of tea."
    repository:
      ROOT: "~/gitea-repositories"
    repository.pull-request:
      WORK_IN_PROGRESS_PREFIXES: "WIP:,[WIP]:"
```

### Default Configuration

This chart will set a few defaults in the Gitea configuration based on the service and ingress settings.
All defaults can be overwritten in `gitea.config`.

INSTALL_LOCK is always set to true, since we want to configure Gitea with this helm chart and everything is taken care of.

_All default settings are made directly in the generated `app.ini`, not in the Values._

#### Database defaults

If a builtIn database is enabled the database configuration is set automatically.
For example, PostgreSQL builtIn will appear in the `app.ini` as:

```ini
[database]
DB_TYPE = postgres
HOST = RELEASE-NAME-postgresql.default.svc.cluster.local:5432
NAME = gitea
PASSWD = gitea
USER = gitea
```

#### Server defaults

The server defaults are a bit more complex.
If ingress is `enabled`, the `ROOT_URL`, `DOMAIN` and `SSH_DOMAIN` will be set accordingly.
`HTTP_PORT` always defaults to `3000` as well as `SSH_PORT` to `22`.

```ini
[server]
APP_DATA_PATH = /data
DOMAIN = git.example.com
HTTP_PORT = 3000
PROTOCOL = http
ROOT_URL = http://git.example.com
SSH_DOMAIN = git.example.com
SSH_LISTEN_PORT = 22
SSH_PORT = 22
ENABLE_PPROF = false
```

#### Metrics defaults

The Prometheus `/metrics` endpoint is disabled by default.

```ini
[metrics]
ENABLED = false
```

### Additional _app.ini_ settings

> **The [generic](https://docs.gitea.io/en-us/config-cheat-sheet/#overall-default)
> section cannot be defined that way.**

Some settings inside _app.ini_ (like passwords or whole authentication configurations) must be considered sensitive and therefore should not be passed via plain text inside the _values.yaml_ file.
In times of _GitOps_ the values.yaml could be stored in a Git repository where sensitive data should never be accessible.

The Helm Chart supports this approach and let the user define custom sources like
Kubernetes Secrets to be loaded as environment variables during _app.ini_ creation or update.

```yaml
gitea:
  additionalConfigSources:
    - secret:
        secretName: gitea-app-ini-oauth
    - configMap:
        name: gitea-app-ini-plaintext
```

This would mount the two additional volumes (`oauth` and `some-additionals`) from different sources to the init container where the _app.ini_ gets updated.
All files mounted that way will be read and converted to environment variables and then added to the _app.ini_ using [environment-to-ini](https://github.com/go-gitea/gitea/tree/main/contrib/environment-to-ini).

The key of such additional source represents the section inside the _app.ini_.
The value for each key can be multiline ini-like definitions.

In example, the referenced `gitea-app-ini-plaintext` could look like this.

```yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: gitea-app-ini-plaintext
data:
  session: |
    PROVIDER=memory
    SAME_SITE=strict
  cron.archive_cleanup: |
    ENABLED=true
```

Or when using a Kubernetes secret, having the same data structure:

```yaml
apiVersion: v1
kind: Secret
metadata:
  name: gitea-security-related-configuration
type: Opaque
stringData:
  security: |
    PASSWORD_COMPLEXITY=off
  session: |
    SAME_SITE=strict
```

#### User defined environment variables in app.ini

Users are able to define their own environment variables, which are loaded into the containers.
We also support to directly interact with the generated _app.ini_.

To inject self defined variables into the _app.ini_ a certain format needs to be honored.
This is described in detail on the [env-to-ini](https://github.com/go-gitea/gitea/tree/main/contrib/environment-to-ini) page.

Prior to Gitea 1.20 and Chart 9.0.0 the helm chart had a custom prefix `ENV_TO_INI`.
After the support for a custom prefix was removed in Gite core, the prefix was changed to `GITEA`.

For example a database setting needs to have the following format:

```yaml
gitea:
  additionalConfigFromEnvs:
    - name: GITEA__DATABASE__HOST
      value: my.own.host
    - name: GITEA__DATABASE__PASSWD
      valueFrom:
        secretKeyRef:
          name: postgres-secret
          key: password
```

Priority (highest to lowest) for defining app.ini variables:

1. Environment variables prefixed with `GITEA`
1. Additional config sources
1. Values defined in `gitea.config`

### External Database

Any external database listed in [https://docs.gitea.io/en-us/database-prep/](https://docs.gitea.io/en-us/database-prep/) can be used instead of the built-in PostgreSQL.
In fact, it is **highly recommended** to use an external database to ensure a stable Gitea installation longterm.

If an external database is used, no matter which type, make sure to set `postgresql.enabled` to `false` to disable the use of the built-in PostgreSQL.

```yaml
gitea:
  config:
    database:
      DB_TYPE: mysql
      HOST: <mysql HOST>
      NAME: gitea
      USER: root
      PASSWD: gitea
      SCHEMA: gitea

postgresql:
  enabled: false
```

### Ports and external url

By default port `3000` is used for web traffic and `22` for ssh.
Those can be changed:

```yaml
service:
  http:
    port: 3000
  ssh:
    port: 22
```

This helm chart automatically configures the clone urls to use the correct ports.
You can change these ports by hand using the `gitea.config` dict.
However you should know what you're doing.

### ClusterIP

By default the `clusterIP` will be set to `None`, which is the default for headless services.
However if you want to omit the clusterIP field in the service, use the following values:

```yaml
service:
  http:
    type: ClusterIP
    port: 3000
    clusterIP:
  ssh:
    type: ClusterIP
    port: 22
    clusterIP:
```

### SSH and Ingress

If you're using ingress and want to use SSH, keep in mind, that ingress is not able to forward SSH Ports.
You will need a LoadBalancer like `metallb` and a setting in your ssh service annotations.

```yaml
service:
  ssh:
    annotations:
      metallb.universe.tf/allow-shared-ip: test
```

### SSH on crio based kubernetes cluster

If you use `crio` as container runtime it is not possible to read from a remote repository.
You should get an error message like this:

```bash
$ git clone git@k8s-demo.internal:admin/test.git
Cloning into 'test'...
Connection reset by 192.168.179.217 port 22
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
```

To solve this problem add the capability `SYS_CHROOT` to the `securityContext`.
More about this issue [here](https://gitea.com/gitea/helm-chart/issues/161).

### Cache

The cache handling is done via `redis-cluster` (via the `bitnami` chart) by default.
This deployment is HA-ready but can also be used for single-pod deployments.
By default, 6 replicas are deployed for a working `redis-cluster` deployment.
Many cloud providers offer a managed redis service, which can be used instead of the built-in `redis-cluster`.

```yaml
redis-cluster:
  enabled: true
```

### Persistence

Gitea will be deployed as a deployment.
By simply enabling the persistence and setting the storage class according to your cluster everything else will be taken care of.
The following example will create a PVC as a part of the deployment.

Please note, that an empty `storageClass` in the persistence will result in kubernetes using your default storage class.

If you want to use your own storage class define it as follows:

```yaml
persistence:
  enabled: true
  storageClass: myOwnStorageClass
```

If you want to manage your own PVC you can simply pass the PVC name to the chart.

```yaml
persistence:
  enabled: true
  claimName: MyAwesomeGiteaClaim
```

In case that persistence has been disabled it will simply use an empty dir volume.

PostgreSQL handles the persistence in the exact same way.
You can interact with the postgres settings as displayed in the following example:

```yaml
postgresql:
  persistence:
    enabled: true
    claimName: MyAwesomeGiteaPostgresClaim
```

### Admin User

This chart enables you to create a default admin user.
It is also possible to update the password for this user by upgrading or redeploying the chart.
It is not possible to delete an admin user after it has been created.
This has to be done in the ui.
You cannot use `admin` as username.

```yaml
gitea:
  admin:
    username: "MyAwesomeGiteaAdmin"
    password: "AReallyAwesomeGiteaPassword"
    email: "gi@tea.com"
```

You can also use an existing Secret to configure the admin user:

```yaml
apiVersion: v1
kind: Secret
metadata:
  name: gitea-admin-secret
type: Opaque
stringData:
  username: MyAwesomeGiteaAdmin
  password: AReallyAwesomeGiteaPassword
```

```yaml
gitea:
  admin:
    existingSecret: gitea-admin-secret
```

### LDAP Settings

Like the admin user the LDAP settings can be updated.
All LDAP values from <https://docs.gitea.io/en-us/command-line/#admin> are available.

Multiple LDAP sources can be configured with additional LDAP list items.

```yaml
gitea:
  ldap:
    - name: MyAwesomeGiteaLdap
      securityProtocol: unencrypted
      host: "127.0.0.1"
      port: "389"
      userSearchBase: ou=Users,dc=example,dc=com
      userFilter: sAMAccountName=%s
      adminFilter: CN=Admin,CN=Group,DC=example,DC=com
      emailAttribute: mail
      bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
      bindPassword: JustAnotherBindPw
      usernameAttribute: CN
      publicSSHKeyAttribute: publicSSHKey
```

You can also use an existing secret to set the `bindDn` and `bindPassword`:

```yaml
apiVersion: v1
kind: Secret
metadata:
  name: gitea-ldap-secret
type: Opaque
stringData:
  bindDn: CN=ldap read,OU=Spezial,DC=example,DC=com
  bindPassword: JustAnotherBindPw
```

```yaml
gitea:
    ldap:
      - existingSecret: gitea-ldap-secret
        ...
```

⚠️ Some options are just flags and therefore don't have any values.
If they are defined in `gitea.ldap` configuration, they will be passed to the Gitea CLI without any value.
Affected options:

- notActive
- skipTlsVerify
- allowDeactivateAll
- synchronizeUsers
- attributesInBind

### OAuth2 Settings

Like the admin user, OAuth2 settings can be updated and disabled but not deleted.
Deleting OAuth2 settings has to be done in the ui.
All OAuth2 values, which are documented [here](https://docs.gitea.io/en-us/command-line/#admin), are
available.

Multiple OAuth2 sources can be configured with additional OAuth list items.

```yaml
gitea:
  oauth:
    - name: "MyAwesomeGiteaOAuth"
      provider: "openidConnect"
      key: "hello"
      secret: "world"
      autoDiscoverUrl: "https://gitea.example.com/.well-known/openid-configuration"
      #useCustomUrls:
      #customAuthUrl:
      #customTokenUrl:
      #customProfileUrl:
      #customEmailUrl:
```

You can also use an existing secret to set the `key` and `secret`:

```yaml
apiVersion: v1
kind: Secret
metadata:
  name: gitea-oauth-secret
type: Opaque
stringData:
  key: hello
  secret: world
```

```yaml
gitea:
  oauth:
    - name: "MyAwesomeGiteaOAuth"
      existingSecret: gitea-oauth-secret
        ...
```

## Configure commit signing

When using the rootless image the gpg key folder is not persistent by default.
If you consider using signed commits for internal Gitea activities (e.g. initial commit), you'd need to provide a signing key.
Prior to [PR186](https://gitea.com/gitea/helm-chart/pulls/186), imported keys had to be re-imported once the container got replaced by another.

The mentioned PR introduced a new configuration object `signing` allowing you to configure prerequisites for commit signing.
By default this section is disabled to maintain backwards compatibility.

```yaml
signing:
  enabled: false
  gpgHome: /data/git/.gnupg
```

Regardless of the used container image the `signing` object allows to specify a private gpg key.
Either using the `signing.privateKey` to define the key inline, or refer to an existing secret containing the key data by using `signing.existingSecret`.

```yaml
apiVersion: v1
kind: Secret
metadata:
  name: custom-gitea-gpg-key
type: Opaque
stringData:
  privateKey: |-
    -----BEGIN PGP PRIVATE KEY BLOCK-----
    ...
    -----END PGP PRIVATE KEY BLOCK-----
```

```yaml
signing:
  existingSecret: custom-gitea-gpg-key
```

To use the gpg key, Gitea needs to be configured accordingly.
A detailed description can be found in the [official Gitea documentation](https://docs.gitea.io/en-us/signing/#general-configuration).

## Metrics and profiling

A Prometheus `/metrics` endpoint on the `HTTP_PORT` and `pprof` profiling endpoints on port 6060 can be enabled under `gitea`.
Beware that the metrics endpoint is exposed via the ingress, manage access using ingress annotations for example.

To deploy the `ServiceMonitor`, you first need to ensure that you have deployed `prometheus-operator` and its [CRDs](https://github.com/prometheus-operator/prometheus-operator#customresourcedefinitions).

```yaml
gitea:
  metrics:
    enabled: true
    serviceMonitor:
      enabled: true

  config:
    server:
      ENABLE_PPROF: true
```

## Pod annotations

Annotations can be added to the Gitea pod.

```yaml
gitea:
  podAnnotations: {}
```

## Themes

Custom themes can be added via k8s secrets and referencing them in `values.yaml`.

```yaml
extraVolumes:
  - name: gitea-themes
    secret:
      secretName: gitea-themes

extraVolumeMounts:
  - name: gitea-themes
    readOnly: true
    mountPath: "/data/gitea/public/css"
```

The secret can be created via `terraform`:

```hcl
resource "kubernetes_secret" "gitea-themes" {
  metadata {
    name      = "gitea-themes"
    namespace = "gitea"
  }

  data = {
    "theme-custom.css"      = "${file("FULL-PATH-TO-CSS")}"
    "theme-custom-dark.css" = "${file("FULL-PATH-TO-CSS")}"
  }

  type = "Opaque"

  depends_on = [kubernetes_namespace.gitea]
}
```

or natively via `kubectl`:

```bash
kubectl create secret generic gitea-themes --from-file={{FULL-PATH-TO-CSS}} --namespace gitea
```

## Upgrading

This section lists major and breaking changes of each Helm Chart version.
Please read them carefully to upgrade successfully, especially the change of the **default database backend**!
If you miss this, blindly upgrading may delete your Postgres instance and you may lose your data!

<details>

<summary>To 9.0.0</summary>

This chart release comes with many breaking changes while aiming for a HA-ready setup.
Please go through all of them carefully to perform a successful upgrade.
Here's a brief summary again, followed by more detailed migration instructions:

- Switch from `Statefulset` to `Deployment`
- Switch from `Memcached` to `redis-cluster` as the default session and queue provider
- Switch from `postgres` to `postgres-ha` as the default database provider
- A chart-internal PVC bootstrapping logic
  - New `persistence.mount`: whether to mount an existent PVC (even if not creating it)
  - New `persistence.create`: whether to create a new PVC
  - Renamed `persistence.existingClaim` to `persistence.claimName`

While not required, we recommend to start with a RWX PV for new installations.
A RWX volume is required for installation aiming for HA.

If you want to stay with a pre-existing RWO PV, you need to set

- `persistence.mount=true`
- `persistence.create=false`
- `persistence.claimName` to the name of your existing PVC.

If you do not, Gitea will create a new PVC which will in turn create a new PV.
If this happened to you by accident, you can still recover your data by setting using the settings from above in a subsequent run.

If you want to stay with a `memcache` instead of `redis-cluster`, you need to deploy `memcache` manually (e.g. from [bitnami](https://github.com/bitnami/charts/tree/main/bitnami/memcached)) and set

- `cache.HOST = "<memcache connection string>"`
- `cache.ADAPTER = "memcache"`
- `session.PROVIDER = "memcache"`
- `session.PROVIDER_CONFIG = "<memcache connection string>"`
- `queue.TYPE = "memcache"`
- `queue.CONN_STR = "<memcache connection string>"`

The `memcache` connection string has the scheme `memcache://<memcache service name>:<memcache service port>`, e.g. `gitea-memcached.gitea.svc.cluster.local:11211`.
The first item here (`<memcache service name>`) will be different compared to the example if you deploy `memcache` yourself.

The above changes are motivated by the idea to tidy dependencies but also have HA-ready ones at the same time.
The previous `memcache` default was not HA-ready, hence we decided to switch to `redis-cluster` by default.

If you are coming from an existing deployment and [#356](https://gitea.com/gitea/helm-chart/issues/356) is still open, you need to set the config sections for `cache`, `session` and `queue` explicitly:

```yaml
    session:
      PROVIDER: redis-cluster
      PROVIDER_CONFIG: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
      
    cache:
      ENABLED: true
      ADAPTER: redis-cluster
      HOST: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
      
    queue:
      TYPE: redis
      CONN_STR: redis+cluster://:gitea@gitea-redis-cluster-headless.<namespace>.svc.cluster.local:6379/0?pool_size=100&idle_timeout=180s&
```

<!-- markdownlint-disable-next-line -->
**Transitioning from a RWO to RWX Persistent Volume**

If you want to switch to a RWX volume and go for HA, you need to

1. Backup the data stored under `/data`
2. Let the chart create a new RWX PV (or do it statically yourself)
3. Restore the backup to the same location in the new PV

<!-- markdownlint-disable-next-line -->
**Transitioning from Postgres to Postgres HA**

If you are running with a non-HA PG DB from a previous chart release, you need to set

- `postgresql-ha.enabled=false`
- `postgresql.enabled=true`

This is needed to stay with your existing single-instance DB (as the HA-variant is the new default).

<!-- markdownlint-disable-next-line -->
**Change of env-to-ini prefix**

Before this release, the env-to-ini prefix was `ENV_TO_INI__`.
This allowed a clear distinction between user-provided and chart-provided env-to-ini variables.
Due to the removal custom prefix feature in the upstream implementation of env-to-ini, the prefix has been changed to the default `GITEA__`.

If you previously had defined env vars that had the `ENV_TO_INI__` prefix, you need to change them to `GITEA__` in order for them to be picked up by the chart.

<summary>To 8.0.0</summary>

### Removal of MariaDB and MySQL DB chart dependencies <!-- omit from toc -->

In this version support for DB chart dependencies of MySQL and MariaDB have been removed to simplify the maintenance of the helm chart.
External MySQL and MariaDB databases are still supported and will be in the future.

### Postgres Update from v11 to v15 <!-- omit from toc -->

This Chart version updates the Postgres chart dependency and subsequently Postgres from v11 to v15.
Please read the [Postgres Release Notes](https://www.postgresql.org/docs/release/) for version-specific changes.
With respect to `values.yaml`, parameters `username`, `database` and `password` have been regrouped under `auth` and slightly renamed.
`persistence` has also been regrouped under the `primary` key.
Please adjust your `values.yaml` accordingly.

**Attention**: The Postgres upgrade is not automatically handled by the chart and must be done by yourself.
See [this comment](https://gitea.com/gitea/helm-chart/issues/452#issuecomment-740885) for an extensive walkthrough.
We again highly encourage users to use an external (managed) database for production instances.

</details>

<details>

<summary>To 7.0.0</summary>

### Private GPG key configuration for Gitea signing actions <!-- omit from toc -->

Having `signing.enabled=true` now requires to use either `signing.privateKey` or `signing.existingSecret` so that the Chart can automatically prepare the GPG key for Gitea internal signing actions.
See [Configure commit signing](#configure-commit-signing) for details.

</details>

<details>

<summary>To 6.0.0</summary>

### Different volume mounts for init-containers and runtime container <!-- omit from toc -->

**The `extraVolumeMounts` is deprecated** in favor of `extraInitVolumeMounts` and `extraContainerVolumeMounts`.
You can now have different mounts for the initialization phase and Gitea runtime.
The deprecated `extraVolumeMounts` will still be available for the time being and is mounted into every container.
If you want to switch to the new settings and want to mount specific volumes into all containers, you have to configure their mount points within both new settings.

**Combining values from the deprecated setting with values from the new settings is not possible.**

### New `enabled` flag for `startupProbe` <!-- omit from toc -->

Prior to this version the `startupProbe` was just a commented sample within the `values.yaml`.
With the migration to an auto-generated [Parameters](#parameters) section, a new parameter `gitea.startupProbe.enabled` has been introduced set to
`false` by default.

If you are using the `startupProbe` you need to add that new parameter and set it to `true`.
Otherwise, your defined probe won't be considered after the upgrade.

</details>

<details>

<summary>To 5.0.0</summary>

> 💥 The Helm Chart now requires Gitea versions of at least 1.11.0.

### Enable Dependencies <!-- omit from toc -->

The values to enable the dependencies, such as PostgreSQL, Memcached, MySQL and MariaDB have been moved from `gitea.database.builtIn.` to the dependency values.

You can now enable the dependencies as followed:

```yaml
memcached:
  enabled: true

postgresql:
  enabled: true

mysql:
  enabled: false

mariadb:
  enabled: false

### App.ini generation <!-- omit from toc -->

The app.ini generation has changed and now utilizes the environment-to-ini script provided by newer Gitea versions.
This change ensures, that the app.ini is now persistent.

### Secret Key generation <!-- omit from toc -->

Gitea secret keys (SECRET_KEY, INTERNAL_TOKEN, JWT_SECRET) are now generated automatically in certain situations:

- New install: By default the secrets are created automatically.
  If you provide secrets via `gitea.config` they will be used instead of automatic generation.
- Existing installs: The secrets won't be deployed, neither via configuration nor via auto generation.
  We explicitly prevent to set new secrets.

> 💡 It would be possible to set new secret keys manually by entering the running container and rewriting the app.ini by hand.
> However, this it is not advisable to do so for existing installations.
> Certain settings like _LDAP_ would not be readable anymore.

### Probes <!-- omit from toc -->

`gitea.customLivenessProbe`, `gitea.customReadinessProbe` and `gitea.customStartupProbe` have been removed.

They are replaced by the settings `gitea.livenessProbe`, `gitea.readinessProbe` and `gitea.startupProbe` which are now fully configurable and used _as-is_ for
a Chart deployment.
If you have customized their values instead of using the `custom` prefixed settings, please ensure that you remove the `enabled` property from each of them.

In case you want to disable one of these probes, let's say the `livenessProbe`, add the following to your values.
The `podAnnotation` is just there to have a bit more context.

```diff
gitea:
+ livenessProbe:
  podAnnotations: {}
```

### Multiple OAuth and LDAP authentication sources <!-- omit from toc -->

With `5.0.0` of this Chart it is now possible to configure Gitea with multiple OAuth and LDAP sources.
As a result, you need to update an existing OAuth/LDAP configuration in your customized `values.yaml` by replacing the object with settings to a list
of settings objects.
See [OAuth2 Settings](#oauth2-settings) and [LDAP Settings](#ldap-settings) section for details.

### Ingress changes <!-- omit from toc -->

To provide a more flexible Ingress configuration we now support not only host settings but also provide configuration for the path and pathType.
So this change changes the hosts from a simple string list, to a list containing a more complex object for more configuration.

```diff
ingress:
  enabled: false
  annotations: {}
    # kubernetes.io/ingress.class: nginx
    # kubernetes.io/tls-acme: "true"
-  hosts:
-    - git.example.com
+  hosts:
+    - host: git.example.com
+      paths:
+        - path: /
+          pathType: Prefix
  tls: []
  #  - secretName: chart-example-tls
  #    hosts:
  #      - git.example.com
```

If you want everything as it was before, you can simply add the following code to all your host entries.

```yaml
paths:
  - path: /
    pathType: Prefix
```

### Dropped kebab-case support <!-- omit from toc -->

In 3.x.x it was possible to provide an ldap configuration via kebab-case, this support has now been dropped and only camel case is supported.
See [LDAP section](#ldap-settings) for more information.

### Dependency update <!-- omit from toc -->

The chart comes with multiple databases and Memcached as dependency, the latest release updated the dependencies.

- Memcached: `4.2.20` -> `5.9.0`
- PostgreSQL: `9.7.2` -> `10.3.17`
- MariaDB: `8.0.0` -> `9.3.6`

If you're using the builtin databases you will most likely redeploy the chart in order to update the database correctly.

### Execution of initPreScript <!-- omit from toc -->

Generally spoken, this might not be a breaking change, but it is worth to be mentioned.

Prior to `4.0.0` only one init container was used to both setup directories and configure Gitea.
As of now the actual Gitea configuration is separated from the other pre-execution.
This also includes the execution of _initPreScript_.
If you have such script, please be aware of this.
Dynamically prepare the Gitea setup during execution by e.g. adding environment variables to the execution context won't work anymore.

### Gitea Version 1.14.X repository ROOT <!-- omit from toc -->

Previously the ROOT folder for the Gitea repositories was located at `/data/git/gitea-repositories`.
In version `1.14` has the path been changed to `/data/gitea-repositories`.

This chart will set the `gitea.config.repository.ROOT` value default to `/data/git/gitea-repositories`.
