I am trying to run the Fabric 2.0 test-network in Kubernetes (locally, in minikube) and am facing an issue with the installing or running of the chaincode by the peers (in a docker container, it seems).

I created kubernetes files based on the docker-compose-test-net.yaml and successfully deployed the network, generated the crypto material, created and joined the channel, installed the chaincode on the peers, commited its definition. But when I try to invoke it, I have the following error:

Error: endorsement failure during invoke. response: status:500 message:"error in simulation:
failed to execute transaction 68e996b0d17c210af9837a78c0480bc7ba0c7c0f84eec7da359a47cd1f5c704a:

chaincode registration failed: container exited with 0"

I included in that pastebin the logs of the peer. We can see in there that it starts the container, but then I don't understand what happens with it: https://pastebin.com/yrMwG8Nd

I then tried as explained here: https://github.com/IBM/blockchain-network-on-kubernetes/issues/27. Where they say that

IKS v1.11 and onwards now use containerd as its container runtime instead of the docker engine therefore using docker.sock is no longer possible.

And they propose to deploy a docker pod (dind) with that file and that file and change the occurences of unix:///host/var/run/docker.sock to tcp://docker:2375.

But then I have the following error when I try to install the chaincode:

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:
cannot connect to Docker endpoint

So it seems it cannot connect to the Docker endpoint. But I cannot find how to fix this.

If you have an idea, it would help a lot!
