Base container archive

What is the idea?

to generate new base container fast, user auto-increment (patchlevel) and make all builds in the cluster.

So it uses ENV variables to get the actual patchlevel (build tag is always builder).

Start

• Create a Project baseimages
• oc create rolebinding registry-viewer --clusterrole=registry-viewer --group=system:authenticated -n baseimages
• ssh-keygen -t rsa -N "" -f git-ssh-key
• oc create secret generic git-ssh-key --from-file=ssh-privatekey=./git-ssh-key --type=kubernetes.io/ssh-auth -n baseimages
• Create a new ssh key and put it in your git repo as access key
  • in gitlab: "Settings -> Repository -> Deploy Keys" --> Put your public key in here ;-)

Make a new base image

• copy example/* to new subdir
• adapt Dockerfile
• rename and adapt BuildConfig_pflaeging-net-example.yaml
• rename and adapt ImageStream_pflaeging-net-example.yaml
• oc apply -f .
• ../make-build.py .

adapt base image

• enter directory (for example example ;-))
• adapt your code
• optional set a new major version or minor version (we're using SemVer here)
• git commit and push your work (the build system get's the version from the git repo!)
• patch version is automatic incremented

other things

Try ./make-build.py -h
