Openshift build secrets for cloning git repos using SSH Keys

• To create ssh secret:

oc create secret generic sshsecret \
    --from-file=ssh-privatekey=$HOME/.ssh/id_rsa

So I found this by googling for prometheusoperator.0.27.0

Found it in Google's cache: https://webcache.googleusercontent.com/search?q=cache:u0dOwNTOWH0J:https://github.com/operator-framework/community-operators/blob/master/upstream-community-operators/prometheus/prometheusoperator.0.27.0.clusterserviceversion.yaml+&cd=1&hl=en&ct=clnk&gl=us

It looks like there was a 0.32.0 version added to OperatorHub 8 days ago, but maybe it's not published yet. https://github.com/operator-framework/community-operators/tree/master/upstream-community-operators/prometheus

So just create a new project my-prometheus, update metadata.namespace from 'placeholder' to 'my-prometheus'
