finch VS containerd

I was getting hundreds of permissions errors. Oh no, I knew this was going too well. Looking at the current issues within the Finch GitHub repo, I found an issue that I thought would help resolve this problem. Looking at this I created a new docker-compose file to take into consideration some of the comments, as well as adding a new step.

You can also try finch from AWS which combines a similar stack

I work at AWS and helped with testing finch during development

I've not used this myself, but they are pushing this at work instead of having to pay for Docker Desktop - Check out Finch - OpenSource

Lima is still quite new and I am even newer to it so bear in mind that there may be better ways to wield this weapon. There is also a lot of development in this space with the likes of Finch, Multipass and others offering potential alternatives or simplifications to this approach so watch this space!

Containerd and nerdctl

Kubernetes on the backend used to utilize docker for much of its container runtime solutions. One of the modular features of Kubernetes is the ability to utilize a Container Runtime Interface or CRI. The problem was that Docker didn't really meet the spec properly and they had to maintain a shim to translate properly. Instead users could utilize the popular containerd or cri-o runtimes. These follow the Open Container Initiative or OCI's guidelines on container formats.

Container Engine: A runtime that executes and manages containers. Docker and containerd are popular container engines.

Multiple container runtimes are supported, like conatinerd, cri-o, or other CRI compliant runtimes.

This is a failed attempt to upstream part of containerd changes: https://github.com/containerd/containerd/pull/8789

Other part of containerd changes waits for gods-know-what: https://github.com/containerd/containerd/pull/9054

But I haven't gave up yet.

containerd is required by kubernetes to handle containers on its behalf. A big thanks to the HostAfrica blog for the information on setting containerd up for debain. So the containerd install will need to happen on both the WSL2 instance and the Raspberry Pis. For WSL2 you can just install containerd directly:

The context deadline exceeded: unknown is also in containerd, and is a known problem.

Docker Desktop adds a bunch of stuff to simplify local development and that’s why it has a larger memory footprint. You don’t use that when deploying but something like https://containerd.io/.
