Google Cloud authentication
We experienced inconsistencies when multiple google accounts were used with the gcloud cli.
If pulling the docker image indicates permission problems you could check the followings. Unfortunately, our experience shows that any one of these can work, but neither of them is guaranteed.
# check if the active account is surename.lastname@emarsys.com
gcloud auth list
# if not, run and try pulling again
gcloud auth login
# if this does not work, you can try removing your docker credentials from the keychain, and run
docker login eu.gcr.io
gcloud auth configure-docker
# you can also try to remove your application-default login file and log in again
rm ~/.config/gcloud/application_default_credentials.json
gcloud auth application-default login
