fish 🐟 + docker 🐳

Ubuntu LTS container with fish installed as the default shell.

• Available on Docker Hub at https://hub.docker.com/r/dideler/fish-shell
• Available on GitHub at https://github.com/users/dideler/packages/container/package/fish-shell

Use case

Useful when wanting to play around with fish in a pristine and ephemeral environment.
Useful when reproducibility is desired (e.g. controlled environment for running a fish package CI pipeline).

Not intended for developing on the fish codebase.
To build the shell from source with the help of Docker, see fish-shell's Dockerfile instead.

Versions

See image tags on DockerHub or on GitHub for available fish versions.

Images are based on the latest Ubuntu LTS available at the time of building.
