Similar to the Java testcontainers issue: testcontainers/testcontainers-java#4847, it could be useful to accept non-existent ~/.docker/config.json when finding docker auth configs.
Currently, when starting a container by building a Dockerfile using testcontainers.FromDockerfile, a ~/.docker/config.json is required, even if no credentials are needed to build the Dockerfile. This is an issue in environments that don't have a ~/.docker/config.json by default, such as on AWS CodeBuild, as it causes tests to fail. For example, an output of a failed test when running without a ~/.docker/config.json:
--- FAIL: TestHandler (10.81s)
test.go:60:
Error Trace: /codebuild/output/src3804529192/src/actions-runner/_work/orcabus/orcabus/lib/workload/stateless/stacks/fmannotator/internal/test/test.go:60
/codebuild/output/src3804529192/src/actions-runner/_work/orcabus/orcabus/lib/workload/stateless/stacks/fmannotator/internal/test/test.go:86
/codebuild/output/src3804529192/src/actions-runner/_work/orcabus/orcabus/lib/workload/stateless/stacks/fmannotator/handlers_test.go:70
Error: Received unexpected error:
create container: build options: auth configs from Dockerfile: open /root/.docker/config.json: no such file or directory
Test: TestHandler
FAIL
A workaround is to create an empty ~/.docker/config.json or set the DOCKER_CONFIG environment variable.
I think this could be fixed by changing how the errors are handled in getDockerAuthConfigs by returning an empty map[string]registry.AuthConfig instead of an error if ~/.docker/config.json could not be found.
