Add --ipfs-address to nerdctl pull

[felipecruz91]

What is the problem you're trying to solve

Hi,

I'm experimenting with pushing OCI images to IPFS, so bear in mind that the following set-up is likely not ideal.

The IPFS daemon is running in a container in Docker Desktop instead of directly on the host. It is reachable from the host at localhost:5001.

Because I'm using MacOS, I had to run a Lima VM so I can use nerdctl in it. From the Lima VM, I can push an image to the IPFS daemon by specifying --ipfs-address:

lima nerdctl push --ipfs-address /ip4/192.168.5.2/tcp/5001 ipfs://postgres
INFO[0000] pushing image "postgres" to IPFS
INFO[0000] ensuring image contents

So far so good, but when I try to pull the image, I get the following error:

lima nerdctl pull ipfs://bafkreigolp7bq76elja3ircgz2xs2m5gbz5aznhruvvgzw4akkfdy7x77q
FATA[0000] ipfs api address could not be found

I understand that the reason why nerdctl pull ipfs:// fails is because it requires the IPFS daemon to be running on the host. However, as I mentioned, the IPFS daemon is running in a container in Docker Desktop.

Describe the solution you'd like

I'd like nerdctl pull to support --ipfs-address so I can specify the IPFS address where the daemon is running:

lima nerdctl pull --ipfs-address /ip4/192.168.5.2/tcp/5001 ipfs://postgres

Additional context

limactl --version
limactl version 0.12.0
