Compose with nerdctl ?

[luizhpriotto]

How can I use the nerdctl extension with "docker-compose"?

Something like:

load('ext://nerdctl', 'nerdctl_build')
docker_compose('docker-compose.yml')
nerdctl_build('testimage', context='.', dockerfile='Dockerfile',
  live_update = [
    sync('.', '/var/www/html')
  ])

Thanks,

i haven't tried it, but i don't see any reason why it wouldn't work if you have nerdctl compose symlinked correctly as docker compose. what happened when you ran that tiltfile? what did you expect to happen?

I've experimented with using nerdctl as a Docker replacement, and simply symlinking docker to nerdctl isn't sufficient. I created a symlinked wrapper for docker-compose that uses nerdctl compose and set up a proxy for the Docker socket since Tilt uses the REST API for logging.
I've put together a working solution in this repository: https://github.com/ThomasGavaix/tilt-nerdctl
What are your thoughts on adding native nerdctl client support to Tilt, alongside the existing Docker and Kubernetes integrations?

[nicks]

@ThomasGavaix a lot depends on the overhead of implementation. for example, there are already a lot of projects that implement docker socket compatibility over different container runtimes, having a custom nerdctl docker socket shim in tilt would be pretty high maintenance overhead.

I've switched from Docker to containerd as my local container runtime (running containers directly without Kubernetes). I'd like to continue using Tilt for development. What's the current best approach for integrating Tilt with containerd ?
