Docker image with tools like curl, ping, netcat, nslookup, host, dig, psql, redis-cli etc.
For example, to run a one-off container in Kubernetes:
kubectl run --rm utils -it --generator=run-pod/v1 --image dceschmidt/utils bash
# You will be seeing a bash prompt
$ curl https://google.com
...
...
$ exit
Note: --rm
option will delete the pod
after exiting from the container
$ docker pull dceschmidt/utils
$ docker run --rm -it dceschmidt/utils bash
# inside the container
$ ping google.com
$ ifconfig
...
$ exit
