## 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`
|
|
|
|
|
1. Run `ci/docker-rust-nightly/build.sh` to rebuild the nightly image locally
|
|
|
|
|
1. Run `ci/docker-run.sh --nopull solanalabs/rust-nightly ci/test-nightly.sh` to
|
|
|
|
|
confirm the new nightly image builds. Fix any issues as needed
|
|
|
|
|
1. 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.**
|
|
|
|
|
1. Merge the update to `ARG nightly=xyz` and any codebase adjustments needed.
