What are you connecting it to? Are you exec?

Yes. I have built haproxy image alpinelinux 1.8 and launched the container. the container is running fine. This has entry point. I tried connecting to it using shell and as well as entrypoint but dont have any luck. I can see logs of container etc with docker logs but would like to connect to it. thank you

sudo docker exec -it 8d9299a55b4c bash
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused “process_linux.go:110: decoding init error from pipe caused “read parent: connection reset by peer””

The haproxy docker image is using docker-entrypoint.sh. I am using the following docker image. thanks

Try
sudo docker exec -it 8d9299a55b4c sh
or
sudo docker exec -it 8d9299a55b4c /bin/bash

I tried this before and didn’t work. I have also launched a new container now. I think this has to do with the entrypoint or may be entrypoint need to be specified as argument. I even speifying entrypoint as well that didn’t work either. Below are the output of sh and /bin/bash with -exec. thank you

I am not sure tell you the truth. I would google the whole error. I see a lot of other people had the same problem.

I was able to fix it by downgrading the docker. it turned out an issue with centos rpm. thx for your help.
