Docker 图像无法在 Google Container Registry 上构建

Question

I have setup a trigger from Bitbucket to Google Container Registry. I have a Dockerfile in the root, and am able to build the container fine from my local machine.

I get this error in Google Container Registry when the trigger runs (I did not modify the command that GCR wanted to run - it's the default). My project name has been replaced with "project":

Answer 1

It looks like the image's tag is missing (after the ":").

Do you have a cloudbuild.yaml config file? If so do you use some substitutions variables (eg $REVISION_ID )? Maybe there is a misspelling there?

Answer 2

For others who come along, when running into this same issue when pushing a Dockerfile with a Cloud Build YAML file - my mistakes:

1. Had ${SHORT_SHA} in one place and not the other (was on the Artifact push and not the build) [ https://stackoverflow.com/a/44716934/18176030 credit to Philmod for the tag not being right]
2. I was using the "grc.io" on during the build process and not the Artifact push (was using "us-east1-docker.pkg.dev").
