README.md

Docker image containing rust nightly and some preinstalled crates used in CI.

This image may be manually updated by running CI=true ./build.sh if you are a member of the Solana Labs Docker Hub organization, but it is also automatically updated periodically by this automation.

Moving to a newer nightly

We pin the version of nightly (see the ARG nightly=xyz line in Dockerfile) to avoid the build breaking at unexpected times, as occasionally nightly will introduce breaking changes.

To update the pinned version:

  1. Locally update the ARG nightly=xyz line in ci/docker-rust-nightly/Dockerfile
  2. Run ci/docker-rust-nightly/build.sh to rebuild the nightly image locally
  3. Run SOLANA_DOCKER_RUN_NOSETUID=1 ci/docker-run.sh --nopull solanalabs/rust-nightly ci/test-nightly.sh to confirm the new nightly image builds. Fix any issues as needed
  4. Run docker login to enable pushing images to Docker Hub, if you're authorized.
  5. Run CI=true ci/docker-rust-nightly/build.sh to push the new nightly image to dockerhub.com. Note that all CI may be broken now until the next step is completed.
  6. Merge the update to ARG nightly=xyz and any codebase adjustments needed.

Troubleshooting

Resource is denied

When running CI=true ci/docker-rust-nightly/build.sh, you see:

denied: requested access to the resource is denied

Run docker login to enable pushing images to Docker Hub. Contact @mvines or @garious to get write access.
