This container does nothing but pause waiting for signals. It will gracefully terminate immediately when it receives one.
It is designed for use in diagnosing Kubernetes, e.g. you can create a pod with this, it will stay running, and then exec into it as needed.
The alternative would be a command of 'sleep' or 'tail -f /dev/null' but these do not terminate gracefully.
You can run this from docker:
docker run --rm -it agilicus/pause
but the most likely use is to create a long-lived Kubernetes pod.
You can do this with kubectl run:
kubectl run debug --restart=Never --image=agilicus/pause
You can also do this declaratively:
cat << EOF | kubectl create -f -
---
apiVersion: v1
kind: Pod
metadata:
name: debug
spec:
containers:
- name: debug
image: agilicus/pause
EOF
When done, run kubectl delete pod/debug
There are no tools installed in the container. To add them, run apt-get update; apt-get install <tool>.
Simple tools you might want:
- curl
- fping
- tcpdump
- jq
- python3
