Is IPFS+estargz working? #3475

Open apostasie opened 1 month ago

apostasie commented 1 month ago

Description

Be sure to serve locally nerdctl ipfs registry serve --listen-registry localhost:5555 and to have a completely clean, IPFS ready environment.

Then manually start a local registry: nerdctl ipfs registry serve --listen-registry localhost:5555

And:

export CONTAINERD_SNAPSHOTTER=stargz

# Clean before
nerdctl rmi --namespace=nerdctl-test -f localhost:5555/ipfs/bafkreicztjlfrhs5aes457yyb5nnbjgsjw6wgin4krjed4f2uxqbxa5ypu
nerdctl rmi --namespace=nerdctl-test -f bafkreicztjlfrhs5aes457yyb5nnbjgsjw6wgin4krjed4f2uxqbxa5ypu

# Pull
nerdctl pull --namespace=nerdctl-test ghcr.io/stargz-containers/alpine:3.13-org
# Push
nerdctl push --namespace=nerdctl-test ipfs://ghcr.io/stargz-containers/alpine:3.13-org --estargz

# Pull from ipfs
nerdctl pull --namespace=nerdctl-test ipfs://bafkreicztjlfrhs5aes457yyb5nnbjgsjw6wgin4krjed4f2uxqbxa5ypu
# Run
nerdctl run --namespace=nerdctl-test --rm ipfs://bafkreicztjlfrhs5aes457yyb5nnbjgsjw6wgin4krjed4f2uxqbxa5ypu ls /.stargz-snapshotter

It seems like pulling solely from ipfs://CID, or from the locally served registry yields different results - one of the image seems to be on stargz, but not the other.

I do not see any difference between the two images, nor the containers, but there seems to be something amiss here.

Note that the same problem appears to happen when pulling with --ipfs-address

Or am I missing something here?
