Removed

• Remove deprecated SpotPrice parameter #1130 (@triarius)
• Removed packages. These packages are either not available on Amazon Linux 2023, or not installed by default on the base image we use. We have decided to not install them, as suitable replacements may be found.
  • Python 2
  • OpenSSL v1.0
  • AWS CLI v1
  • Docker-Compose v1
    • The docker-compose executable will prepend the --compatibility flag to docker-compose v2 #1148 (@triarius)
  • Cronie

Known Issues

• If you invoke docker compose with the docker-compose command, the --compatibilty flag will be prepended for you. This will be the case with the docker-compose-buildkite-plugin unless you specify cli-version: 2 in your plugin config.
• Docker build errors from docker compose will now exit with status code 17 or 18 when previously they would have exited with code 1. Please adjust your retry rules accordingly.
• The docker group is now a system group. Previously, its group ID was hard-coded to be 1001, but now it could take some value from 999 descending. If you relied on the GID being hard-coded to 1001 in your builds, they may have permission errors. We recommend you use something like the bash expression getent group docker | awk -F: '{print $3}' to detect what the ID of the docker group is instead.
