docker exec -it container2 ping container3
We get the following output, which indicates that there’s no network communication between both containers:
ping: bad address 'container3'
The first step to fix this issue is identifying containers that are connected to our network. We use the following command for that:
docker network inspect --format='{{range .Containers}}{{.Name}} {{end}}' mynetwork
mynetwork refers to our network, and we can confirm that only container1 and container2 can communicate with each other. To fix this issue, we connect container3 ...
