It seems the docker failures on the CI are unrelated and happen on other branches as well...
registry-1.docker.io seems to be down, getting 404

[136] Exception in thread "main" com.google.cloud.tools.jib.registry.RegistryErrorException: Tried to pull image manifest for registry-1.docker.io/library/openjdk:17-slim but failed because: registry returned error code 404; possible causes include invalid or wrong reference. Actual error output follows:
[136] {"errors":[{"code":"MANIFEST_UNKNOWN","message":"manifest unknown","detail":"unknown tag=17-slim"}]}
[136] 
[136] 
[136] 	at com.google.cloud.tools.jib.registry.RegistryErrorExceptionBuilder.build(RegistryErrorExceptionBuilder.java:101)
...

Hopefully will get back up soon.
