In the previous few years, I’ve discovered Portainer to be a useful instrument. My go-to technique of deploying Portainer is through a Microk8s cluster, which is the best technique of getting Kubernetes assist rolled into the web-based GUI; nevertheless, when deployed on this style, Portainer will be accessed both through HTTP or HTTPS and doesn’t use SSL certificates. Fortunately, Portainer makes it straightforward to allow the forcing of HTTPS and add your SSL certificates. I’ll present you the way that is completed.
Note: When you pressure HTTPS in Portainer, HTTP entry will not work. Also, after you pressure HTTPS, Portainer doesn’t auto-redirect connections from HTTP to HTTPS, so that you’ll want to tell anybody who accesses Portainer of the brand new handle.
