I have problem login into one container of a multi-container pod. I get the container id from the kubectl describe pod <pod-name>
kubectl describe pod ipengine-net-benchmark-488656591-gjrpc -c <container id> When i try:
kubectl exec -ti ipengine-net-benchmark-488656591-gjrpc -c 70761432854f /bin/bash It says: Error from server: container 70761432854f is not valid for pod ipengine-net-benchmark-488656591-gjrpc

Multiple containers in the same Pod share the same IP address. They can communicate with each other by addressing localhost . For example, if a container in a Pod wants to reach another container in the same Pod on port 8080, it can use the address localhost:8080 .
In other words, if you need to run a single container in Kubernetes, then you need to create a Pod for that container. At the same time, a Pod can contain more than one container, usually because these containers are relatively tightly coupled.
In Kubernetes, you can use a shared Kubernetes Volume as a simple and efficient way to share data between containers in a Pod. For most cases, it is sufficient to use a directory on the host that is shared with all containers within a Pod.
ah once more detailed reading the man page of kubectl exec :
Flags:
-c, --container="": Container name. If omitted, the first container in the pod will be chosen -p, --pod="": Pod name -i, --stdin[=false]: Pass stdin to the container -t, --tty[=false]: Stdin is a TTY So i just used the container name from my manifest.yaml and it worked like charm. Hope this helps others ...
Name of the container: ipengine-net-benchmark-iperf-server
