Disable image build cache

Temporary workaround for #92‘s corrupted images

Should we increase the timeout for the build stage?

[mkuron]

Sure, give it a try. I'm at a conference this week and won't have much time to look into this, so it would be good if you could take care of it.

The master branch just failed because the line

docker/maintainer/docker_build.sh

Line 22 in da1f5cb

test "$CI_COMMIT_REF_NAME" != "master" || cmd "/kaniko/executor --context $PWD --dockerfile Dockerfile-$docker_tag* --destination $CI_REGISTRY/$CI_PROJECT_PATH/$CI_JOB_NAME"

builds the image again, which causes the same files/folders/symlinks to be created again, leading to name conflicts. This was not an issue before since the cached layers were re-used during the second build.

Before kaniko, docker was used to build once and push to 2 destinations. However I could not find a command line option in kaniko to push an image without building it first, and couldn't experiment with the kaniko image as it doesn't seem to run in interactive mode.

Ok, I‘ll try to adapt the build script this evening to only build once.
