Installing operators in Red Hat OpenShift from the CLI is much easier with the new kubectl-operator plugin. Here’s an example of how you can use it to install the Event Streams Operator.
Installing operators in OpenShift from the CLI is a little fiddly. It’s possible, but you have to create a bunch of custom resources that aren’t entirely intuitive, like Subscriptions and OperatorGroups.
It’s easy if you’re using the OpenShift Console web UI, as it does this all for you so you don’t need to worry about it. But sometimes you want to do things from the command line. And the new kubectl-operator plugin looks like it’ll make that much simpler.
I had a quick play with it this evening, and it let me get the Event Streams operator running with three commands. (Compare this with the OpenShift Console web UI equivalent in my Event Streams demo video).
Instructions for installing the plugin are on github. If you haven’t used Krew to enable oc / kubectl plugins before, you’ll need to install that first.
