Just a sample pullable docker util. I use this for CoreOS style toolboxes and pods in K8s.
It's a thicc boi, around 400MB~, so might be best to pull something like alpine-curl, if that's just what you need.
$ make
+------------------+
| ubuntool targets |
+------------------+
build Build ubuntool locally
shell Start a /bin/bash shell on ubuntool container
publish Build locally and publish to registry
Do things:
docker run --rm -i -t ubuntool bash <<<
root@cb50a8b4bda1:/# which k9s
/usr/local/bin/k9s
root@cb50a8b4bda1:/# which ip
/usr/sbin/ip
root@cb50a8b4bda1:/# which iperf3
/usr/bin/iperf3
root@cb50a8b4bda1:/# which ss
/usr/bin/ss
Privileged kube stuff in privileged-ubuntool.yaml, for docker host escalation, like how CoreOS toolbox worked:
docker run --rm -i -t --userns=host -v /:/host:ro --privileged ghcr.io/tolson-vkn/ubuntool:latest
