Docker image for custom_greenlight can't be published because CD_DOCKER_USERNAME or CD_DOCKER_PASSWORD are missing (Ignore this warning if running outside a CD/CI environment)

using image: custom_greenlight:release-v2 in docker-compose.yml

always worked like a charm, first time this happened to me

Can you try again? Appears as though there was connection issues with the Alpine registry

[GUFFMHRZ]

i pruned all containers and removed all images but to no avail, it still fails with the same error

Have you tried any of the solutions here: gliderlabs/docker-alpine#334

[GUFFMHRZ]

yes, i tried configurig DNS, adding network: host to the compose.yml and restarting service, thats all solutions that were possible to try on our setup

Seems to be a hickup on our server side, i set it up anew and it works again now
