* Added debug symbols to many debug dockers.
* For debug images *only*:
1) Archive source files into debug image
2) Archived source is copied into /src
3) Created an empty dir /debug
4) Mount both /src as ro & /debug as rw into every docker
5) Login banner will give some details on /src & /debug
6) Devs can copy core file into /debug and view it from inside a container.
7) Dev may create all gdb logs and other data directly into /debug.
* Dropped redundant REDIS_TOOLS per review comments.
* Added debug symbols to frr package and hence FRR based BGP docker.
* 1) Moved dbg_files.sh to scripts/
2) Src directories to archive are now collected from individual Makefiles.
3) Added few more debug symbols
4) Added few more debug dockers.
Here after no more changes except per review comments.
To debug:
Install required version of debug image in Switch or VM.
Copy core file into /debug of host
Get into Docker
gdb /usr/bin/<daemon> -c /debug/<your core file>
set directory /src/... <-- inside gdb to get the source
For non-in-depth debugging:
Download corresponding debug Docker image (docker-...-dbg.gz) to your VM
Load the image
Run image with entrypoint as 'bash' with dir containing core mapped in.
Run gdb on the core.
* Updated Makefile infrastructure to build debug images.
As a sample, platform/broadcom/docker-orchagent-brcm.mk is updated to add a docker-orchagent-brcm-dbg.gz target.
Now "BLDENV=stretch make target/docker-orchagent-brcm-dbg.gz" will build the debug image.
This debug image can be used in any linux box to inspect core file. If your module's external dependency can be suitably mocked, you my even manually run it inside.
"docker run -it --entrypoint=/bin/bash e47a8fb8ed38"
You may map the core file path to this docker run.
* Dropped the regular binary using DBG_PACKAGES and a small name change to help readability.
* Tweaked the changes to retain the existing behavior w.r.t INSTALL_DEBUG_TOOLS=y.
When this change ('building debug docker image transparently') is extended to all dockers, this flag would become redundant. Yet, there can be some test based use cases that rely on this flag.
Until after all the dockers gets their debug images by default and we switch all use cases of this flag to use the newly built debug images, we need to maintain the existing behavior.
* Build a Docker base image based on Debian Stretch
* Build a config-engine Docker image based on Stretch
* Do not install socat from Debian repo
* Add changes that were made to docker-base since this PR was opened
