sansaid / cake Goto Github PK

This includes README that explains architecture and project structure

Several options:

1. Use credentials entered during docker login (challenge: docker login uses a credential store to store the credentials - this will make it difficult to access credentials entered into docker login)
2. Login to Docker separately through cake (this could just be a wrapper to docker login)
3. cake can work only with public repositories => no need for login

After deciding to split cake into two components, I noticed I haven't planned for support of additional Docker arguments. For now, we should aim to only focus on getting the cake components to work with the --image flag and gradually add support for additional flags.

Currently cake is an agent only application, which directly polls a Docker repository, on the condition that it's:

1. Hosted on Docker Hub
2. Is public

Would be good to evolve cake to work with various other Docker registries and using a webhook system such that:

(key: -> = publishes to; <- = consumes from)
registry -> uniquely generated webhook link for registry -> uniquely generated queue for registry <- agent

Use Docker SDK instead of shelling to CLI: https://pkg.go.dev/github.com/docker/docker/client

Currently cake relies on a daemon to run in order to check the registry for changes. It should be possible to run cake without a daemon and run it like podman does with a systemd (need to read more on this).

For the MVP, one architecture is being assumed, but should move towards running images for multiple architectures:

• Create optional --arch flag
• If flag isn't provided, cake should infer the arch from the system it's running from
• If an image for the arch doesn't exist, a clear error message stating this should be sent back

So that it can be distributed and used with apt-get
