Option to access to Docker image built inside industrial_ci

[130s]

@ipa-mdl Is there any reason why there is no way to access the docker image built during industrial_ci process?

I see in a recent change there's an option to docker commit the built image

industrial_ci/industrial_ci/src/docker.sh

Line 114 in d8ac934

docker commit -m "$_COMMIT_IMAGE_MSG" "$cid" $commit_image > /dev/null

, but the option is not publicly exposed (only available when running rerun_ci script AFAIUC). And regardless of which option to start industrial_ci, the built image is deleted

industrial_ci/industrial_ci/src/docker.sh

Line 116 in d8ac934

docker rm "$cid" > /dev/null

.

If there's no problem, I'm interested in adding a generic option to get an access to the built image.

In my usecase, I want to store Docker images with the latest code. To achieve that currently I have CI jobs that run docker build, separately from industrial_ci jobs. While that works ok, since in industrial_ci an image is already built I'm interested in re-using what's already built by industrial_ci. That allows to use the same image for testing on CI and for the future purpose, and also save some CI time (it's non-trivial for a private repo on a hosting service). It could also allow a usecase where the update gets deployed by container (common in web app world, but it's possible in robotics as well).

Yes, #279 was merged while it still was WIP.

but the option is not publicly exposed (only available when running rerun_ci script AFAIUC).

#279 (comment)

Just rename _COMMIT_IMAGE (and perhaps _COMMIT_IMAGE_MSG) and add documentation.

The container gets deleted, but not the image.

@ipa-mdl & @130s

The container gets deleted, but not the image.

I cannot find the image that gets built by industrial CI. i run docker images after the industrial ci script and it doesn't return the recently built image:

  after_script:
    - docker images

Furthermore, looking at the build logs, the last command is docker rm and i do not see a commit of the image.

[mathias-luedtke]

The commit will only happen if _COMMIT_IMAGE is set.
