OCI runtime exec failed: exec failed: container_linux.go:344: starting container process
Before reading this answer just let you know, it's my 2nd day of learning docker, It may not be the perfect help for you.
This error may also occur when the ping package is not installed in the container, I resolved the problem as follow, bash into the container like this
docker container exec -it my_nginx /bin/bashthen install ping package
apt-get updateapt-get install inetutils-pingThis solved my problem.
Please use alpine image of nginx:
docker container run -d --name my_nginx_name nginx:alpine
docker container run -d --name my_nginx_name2 nginx:alpine
Then try to ping using below command:
docker container exec -it my_nginx_name ping my_nginx_name2
Try this it worked for me
# $ docker container exec -it new_nginx bash # apt-get update# apt-get install inetutils-pingDo it for both the container than run your command
# $ docker container exec -it nginx1 ping nginx2
