Temporary build-environment verification for the linux/arm64 image job (reth/Dockerfile). This PR intentionally fails the build after printing environment info and will be closed by its author.

Summary by CodeRabbit

• Known Issues
  • ARM64 Docker builds fail during the build process.
  • Build output may expose sensitive environment and mount information. Do not share affected build logs.

Walkthrough

The op stage in reth/Dockerfile now runs an environment probe. The probe prints system, network, Docker socket, secrets, and mount information, then exits with status 1.

Changes: ARM64 Build Environment Probe

Merge Risk: Moderate · up to 7ceb2

If merged, every image build for this Dockerfile fails, including amd64 builds, because the probe always exits with an error. The PR is described as temporary and meant to be closed. Do not merge it, or gate the probe to arm64 first.

Full details: Title check

Explanation

The title names the change: a CI check that verifies the linux/arm64 image build environment. The raw summary confirms the PR adds a temporary probe to the op stage of reth/Dockerfile for that purpose. The title is specific and accurate, though it does not mention that the build is designed to fail.

Full details: Description check

Explanation

The description states the purpose: a temporary build-environment verification for the linux/arm64 image job in reth/Dockerfile. It also says the build intentionally fails and the PR will be closed. The template asks for the problem, the solution, and the testing approach. The description omits the linked issue (#INSERT_ISSUE_NUMBER is still a placeholder), gives no technical implementation details, and does not describe testing. The author may treat this as a throwaway probe, which could explain the gaps, but the template sections are still missing.

Resolution

Fill in the template sections. Replace the #INSERT_ISSUE_NUMBER placeholder with a real issue number, or state that no issue applies. Under 'What was the problem?', explain why the linux/arm64 build environment needs verification. Under 'How was it solved?', describe the temporary probe added to the op stage of reth/Dockerfile. Under 'How was it tested?', describe how the probe output was checked. Also note that the build fails by design, so reviewers do not treat the failure as a regression.

Gate the temporary probe so it fails only on arm64.

The op stage runs the probe, and its final exit 1 stops that stage. The final ubuntu stage copies op-node from op, so every default build that targets the final stage needs op and fails at this step. That includes the linux/amd64 image builds in docker-compose.yml and in the pr.yml amd64 job. The arm64-only intent is preserved by checking the architecture first.

The probe also prints hostname, IP addresses, mount sources and options, Docker socket metadata, and /run/secrets listings into build logs. If those logs are visible outside the team, remove those fields.
