Docker images for snapcraft

OCI-compliant container images and their sources are officially supported by the https://github.com/canonical/snapcraft-rocks/ project.

To build a snap with the docker container, you need to choose an image that matches snap base. For example, to build base: core24 snap:

docker run -it -v `pwd`:/project ghcr.io/canonical/snapcraft:8_core24
  • 8 in 8_core24 is the version of snapcraft.
  • \; -v construction at the end is required to see snapcraft output.

For more details, see official snapcraft-rocks repo from Canonical.
