k3d exec as root user into pod / container

Let's assume we have a pod called nginx running in the namespace nginx-test.

kubectl create namespace nginx-test
kubectl run nginx --image=nginx -n nginx-test

1. Check if the current cluster is a k3d cluster

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

echo OK

shutdown() { trap "" EXIT; echo -n 'Shutting down... '; kill -9 $vault_pid; echo OK; exit $1; }
trap "shutdown 0" EXIT
trap "echo; echo 'Got interrupt signal!'; shutdown 255" INT
