When working with resource management solutions, like kubernetes, mesos or swarm, often it is necessary to use a container as a "bridge" for getting into the cluster, and investigate a problem.
fabriziopandini/pause is minimal container that hangs waiting for SIGTERM, thus allowing to use
kubectl exec or
docker exec into the container.
The container exists in many variants:
:latest-scratch is provided, allowing to create tiny container placeholders, but without the capability of running a bash into it. This can be used for instance for creating "dummy" sidecar containers in pods.
