[Research] How to get back into GHE

[fokusferit]

As with CDP we could move back to GHE. Investigate how we can use CircleCI set up within CDP and move back to GHE.

Current state:

• CDP allows us to configure easily with a YAML file our CI pipeline, it is similiar to CircleCI, TravisCI in a way that for PR testing you define commands which needs to be executed succesfully.

Limitations:

• CDP doesn't allow to push a commit back to the source repository. Generally it limits any access to internal GHE. Therefore it is not possible to automatically bump our package.json number and do automated npm releases, create git releases with Changelog etc.

• A possible solution might be to use a deployment workflow where we create a docker image on aws and access the repository via this image. Issue here is that you can't use this functionality until you have a Zalando-X-Team which is officially registered.

Outcome:

• We could move back to GHE but we would need to do manual releases, e.g. run a release-script which is basically doing the release steps from our circle.yaml file , this might not be a huge time consuming issue but it would be a manual step which a) we need to do after each PR merge or b) on a regular basis (weekly, bi-weekly, daily...)
