ci-container

Provide a container for running CircleCI jobs.

Configuration Files

Dockerfile

The Dockerfile builds a container based on CircleCI's cimg/rust which contains the latest (in the available image) rust compiler.

To this we add:

  • rust stable, beta, and nightly compilers
  • rust minimum compiler as specified by MIN_RUST_VERSION
  • cargo release & nextsv binaries used in our CircleCI configs

Makefile

The Makefile builds, tags and publishes the container image to the container repository. The image is tagged with the MIN_RUST_VERSION requested.

Usage

Generating container images

Use make to build and publish an image to the repo.

MIN_RUST_VERSION=1.49.0 make publish-tag

If the MIN_RUST_VERSION is not specified the default is 1.56.0.

Usage in CircleCI

Specify the repo, image and tag for the required minimum rust version at the top of the CircleCI config.

version: 2.1

executors:
  rust-env:
    docker:
      - image: cimg/rust:1.62
