In a previous post I discussed a convenient shell alias for elevating kubectl command privileges. Below is a similar alias to do the same, but for helm commands.
The alias relies on using kubie, a tool I highly recommend for your day-to-day Kubernetes interactions. It has some excellent features that simplify a lot of the repetition around the kubectl command. Another dependency is yq for parsing a YAML file.
# Impersonate -admin in current kubie namespace
kubieHelmAsAdmin() {
KUBENS=$(cat $KUBIE_KUBECONFIG | yq '.contexts[0].context.namespace')
helm --kube-as-user $KUBENS-admin $(echo "$@")
}
alias helma='kubieHelmAsAdmin'
Now it’s a matter of using helma <command> to run commands as the elevated user.
