Ah, thanks! It surprised me that nobody had seen this one before me. Hopefully the title of my email will make it easier for others who run into this problem to find this thread. Searching for an answer didn't lead me anywhere...

It seems that people already bumped into a similar issue, see here: https://lists.hyperledger.org/g/fabric/message/9108
And what needs to be done is you need to turn off the 'use gRPC FUSE' fuse option in your docker settings.

I upgraded my Docker install on my Mac to the latest version that just came out to find out that Fabric stopped working. It appears to break the way we use Docker in Docker to install chaincode:

$ peer lifecycle chaincode install fabcar.tar.gz
Error: chaincode install failed with status: 500 - failed to invoke backing implementation of `InstallChaincode': could not build chaincode: docker build failed: docker image inspection failed: Get "http://unix.sock/images/dev-peer0.org1.example.com-fabcar_1-65710fa851d5c73690faa4709ef40b798c085e7210c46d44f8b1e2d5a062c9b0-0ca9287fd994c9e3127d7fbba2f50ee23bae41fca7349e5a02c07da5bccc19d2/json": dial unix /host/var/run/docker.sock: connect: no such file or directory

I'm no expert here so somebody with better understanding will need to dig this one up but what I noticed is that /host/var/run/docker.sock somehow appears as a symlink within the peer (it is on the host but I don't think that should be surfaced within the container):

$ docker exec -it peer0.org1.example.com ls -l /host/var/run/docker.sock
lrwxr-xr-x 1 root root 67 Oct 9 10:53 /host/var/run/docker.sock -> /Users/lehors/Library/Containers/com.docker.docker/Data/docker.sock

Instead, it looks like this with Docker 2.3.0.5:

 

$ docker exec -it peer0.org1.example.com ls -l /host/var/run/docker.sock
srw-rw----    1 root     root             0 Oct  9 11:27 /host/var/run/docker.sock

If you need to downgrade back to the previous version of Docker the link to the older version is available from the Docker release notes page:
