faas-cli is also available as a Docker image making it convenient for use in CI jobs such as with a Jenkins pipeline or a task in cron.
There is no "latest" tag, so find the version of the CLI you want to use from the tags page on the Docker Hub. These correspond to the release from GitHub.
Note: the Docker image cannot be used to perform a build directly, but you can use it to generate a build context which can be used with a container builder such as Docker, buildkit or Kaniko in another part of your build pipeline.
Use-cases for the Docker image:
- Generate the build context without running
- Deploy an existing image to a remote server
- Manage secrets with
- Invoke functions via cron with
- Check the health of your remote gateway with
