Adding precautionary check for DockerHub registry availability in dev container cli #1113

Kaniska244 · 2025-11-28T17:09:15Z

Ref: https://github.com/github/codespaces/issues/22031

Description of changes:

The above codespace availability incident was created to address the multiple outages noticed in DockerHub registry which caused downtime for codepaces as devcontainer up and build commands injects syntax directive # syntax=docker/dockerfile:1.4 which forces devcontainer cli to download docker/dockerfile:1.4 parser image from DockerHub registry. This change was added in PR with #syntax directives + buildkit + user namespace remapping by auto-injecting the #syntax directive in dev container build. This is not required for docker engine version v23 onwards as the default moby buildkit version includes docker/dockerfile:1.4 or higher version of the parser. As part of this PR adding precautionary check to call DockerHub registry URL and confirm the availability before auto-injecting the #syntax directive.

Changelog:

Changed src/spec-node/utils.ts by changing the faulty error logging in retry function.
Added a new precautionary check as described above, in src/spec-node/containerFeatures.ts file.

Checklist:

All checks are passed.

LGTM - I'm happy with this, if we've done sufficient testing

We could have made a general utility function in utils.ts to check the dockerhub auth/ registry access status, and placed the image name/version as variables, but i'm happy with this, can extend this in future if we need.

question: What testing have you done here? Can you update the PR description to state this?

Thanks - looks better now ✅

Docker compose with dev container configuration with Dockerfile and without any feature:

Dev container configuration configurations here

Expected Result: API call to check the availability of dockerfile frontend image in DockerHub registry shouldn’t happen and docker/dockerfile:1.4 image shouldn’t be referenced during execution as the syntax directive isn't explicitly included.

Actual Result: As it can be seen in the below log capture from the test workflow log , neither the API call nor the API call can be seen.

Expected Result: API call to check the availability of docker/dockerfile:1.4 image in DockerHub registry must be done and only if that succeeds then docker/dockerfile:1.4 image should be referenced further during execution.

The dev container configuration can be seen here

Expected Result: API call to check the availability of docker/dockerfile:1.4 image in DockerHub registry must be done and fail multiple times and only if that succeeds then docker/dockerfile:1.4 image should be referenced further during execution. To trigger failure to force multiple retries, I had paused for more that 5 min it while debugging in codespace so that the JWT auth token is expired. I couldn’t possibly think of simulating this in the GitHub actions test.

Actual Result: API call done with multiple retries as it can be seen in the log capture below from codespcaes terminal

@Kaniska244 ➜ /workspaces/cli (directive-dockerfile-perser-removal) $

Kaniska244 · 2025-12-02T07:06:35Z

Dev container configuration with features in `devcontainer up` command run with incorrect DockerHub registry url:

The dev container configuration can be seen here

Expected Result: API call to check the availability of docker/dockerfile:1.4 image in DockerHub registry must be done and fail in all five retry attempts and then docker/dockerfile:1.4 image shouldn’t be referenced further during execution. I injected this locally in codespace by using wrong url in code. I couldn’t possibly think of simulating this in the GitHub actions test in the PR as that would have required code change.

Actual Result: API call done with multiple retries as it can be seen in the log capture below from codespcaes terminal

Complete log below for reference:

@Kaniska244 ➜ /workspaces/cli (directive-dockerfile-perser-removal) $

Kaniska244 · 2025-12-02T08:35:52Z

Dev container configuration with features in `devcontainer up` command run with `--omit-syntax-directive` flag as `true`:

The dev container configuration can be seen here

Expected Result: API call to check the availability of docker/dockerfile:1.4 image in DockerHub registry must not be done and docker/dockerfile:1.4 image shouldn’t be referenced further during execution. I injected this locally in codespace.

Actual Result: API call not done and docker/dockerfile:1.4 image isn't downloaded as per the below log capture.

Complete log for reference:
