Gitea 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. But takes a completely different approach in providing a database and cache with dependencies. Additionally, this chart provides LDAP and admin user configuration with values, as well as being deployed as a statefulset to retain stored repositories.

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 or in the repository 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 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 (configuration)
• Memcached (configuration)

Installing

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 section at the bottom of this document for major and breaking changes.

Prerequisites

• Kubernetes 1.12+
• Helm 3.0+
• PV provisioner for persistent data support

Configuration

Gitea offers lots of configuration options. This is fully described in the Gitea Cheat Sheet.

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:

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

Memcached defaults

Memcached is handled the exact same way as database builtIn. Once Memcached builtIn is enabled, this chart will generate the following part in the app.ini:

[cache]
ADAPTER = memcache
ENABLED = true
HOST = RELEASE-NAME-memcached.default.svc.cluster.local:11211

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.

[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.

[metrics]
ENABLED = false

Additional app.ini settings

The generic 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.

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 containerwhere 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.

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.

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:

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 page.

Note that the Prefix on this helm chart is ENV_TO_INI.

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

gitea:
  additionalConfigFromEnvs:
    - name: ENV_TO_INI__DATABASE__HOST
      value: my.own.host
    - name: ENV_TO_INI__DATABASE__PASSWD
      valueFrom:
        secretKeyRef:
          name: postgres-secret
          key: password

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

1. Environment variables prefixed with ENV_TO_INI
2. Additional config sources
3. Values defined in gitea.config

External Database

Any external Database listed in 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.

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:

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:

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.

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:

$ 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.

Cache

This helm chart can use a built in cache. The default is Memcached from bitnami.

memcached:
  enabled: true

If the built in cache should not be used simply configure the cache in gitea.config.

gitea:
  config:
    cache:
      ENABLED: true
      ADAPTER: memory
      INTERVAL: 60
      HOST: 127.0.0.1:9090

Persistence

Gitea will be deployed as a statefulset. 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 statefulset. This PVC will not be deleted even if you uninstall the chart.

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:

persistence:
  enabled: true
  storageClass: myOwnStorageClass

When using PostgreSQL as dependency, this will also be deployed as a statefulset by default.

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

persistence:
  enabled: true
  existingClaim: 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:

postgresql:
  persistence:
    enabled: true
    existingClaim: 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 redeloying 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.

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

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

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

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.

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:

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

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, are available.

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

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:

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

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, 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.

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.

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

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.

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.

gitea:
  metrics:
    enabled: true
    serviceMonitor:
      enabled: true

  config:
    server:
      ENABLE_PPROF: true

Pod annotations

Annotations can be added to the Gitea pod.

gitea:
  podAnnotations: {}

Themes

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

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:

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.

To 8.0.0

Removal of MariaDB and MySQL DB chart dependencies

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

This Chart version updates the Postgres chart dependency and subsequently Postgres from v11 to v15. Please read the Postgres Release Notes 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 for an extensive walkthrough. We again highly encourage users to use an external (managed) database for production instances.

To 7.0.0

Private GPG key configuration for Gitea signing actions

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 for details.

To 6.0.0

Different volume mounts for init-containers and runtime container

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

Prior to this version the startupProbe was just a commented sample within the values.yaml. With the migration to an auto-generated 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.

To 5.0.0

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

Enable Dependencies

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:

memcached:
  enabled: true

postgresql:
  enabled: true

mysql:
  enabled: false

mariadb:
  enabled: false

App.ini generation

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

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

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.

gitea:
+ livenessProbe:
  podAnnotations: {}

Multiple OAuth and LDAP authentication sources

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 and LDAP Settings section for details.

To 4.0.0

Ingress changes

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.

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.

paths:
  - path: /
    pathType: Prefix

Dropped kebab-case support

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 for more information.

Dependency update

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

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

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.
