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](https://hub.docker.com/u/solanalabs/) Docker Hub organization, but it is also automatically updated periodically by [this automation](https://buildkite.com/solana-labs/solana-ci-docker-rust-nightly). ## 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. Run `ci/docker-rust-nightly/build.sh` to rebuild the nightly image locally, or potentially `ci/docker-rust-nightly/build.sh YYYY-MM-DD` if there's a specific YYYY-MM-DD that is desired (default is today's build). Check https://rust-lang.github.io/rustup-components-history/ for build status 1. Update `ci/rust-version.sh` to reflect the new nightly `YYY-MM-DD` 1. Run `SOLANA_DOCKER_RUN_NOSETUID=1 ci/docker-run.sh --nopull solanalabs/rust-nightly:YYYY-MM-DD ci/test-coverage.sh` to confirm the new nightly image builds. Fix any issues as needed 1. Run `docker login` to enable pushing images to Docker Hub, if you're authorized. 1. Run `CI=true ci/docker-rust-nightly/build.sh YYYY-MM-DD` to push the new nightly image to dockerhub.com. 1. Send a PR with the `ci/rust-version.sh` change 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.
