Up to now few years, I’ve discovered Portainer to be a useful instrument. My go-to technique of deploying Portainer is by way of a Microk8s cluster, which is the simplest technique of getting Kubernetes help rolled into the web-based GUI; nevertheless, when deployed on this trend, Portainer could be accessed both by way of HTTP or HTTPS and doesn’t use SSL certificates. Fortuitously, Portainer makes it straightforward to allow the forcing of HTTPS and add your SSL certificates. I’ll present you the way that is carried out.
Be aware: If you drive HTTPS in Portainer, HTTP entry will not work. Additionally, after you drive 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 deal with.
Soar to:
What you must drive Portainer to make use of HTTPS and SSL
You want a operating occasion of Portainer, an SSL certificates and a consumer with admin privileges. The SSL certificates could be both bought or self-signed. You’ll want each an X.509 certificates and a personal key.

add your SSL certificates to Portainer
You’ll want two information: The X.509 certificates and your personal key. It doesn’t matter if these are bought or self-signed keys, however for manufacturing environments, I recommend a key bought from a Certificates Authority reminiscent of DigiCert.
