First off, as the title says, in regards to Rancher I am a total newbie w/ very little understanding of the product. Second, if my issue has already resolved and posted on here elsewhere, please accept my apologies. I spent 4 hours on Google trying to find an answer w/ zero luck.
I have a Rancher environment that I "inherited" from an engineer who is no longer w/ the company and who didn't document anything concerning this environment. The environment has been running for over a year and as of last week I was able to access Rancher via the UI using Firefox. Today I went to login and when I go to the web page, I get "Secure Connection Failed".
I've done some preliminary troubleshooting (again, I'm a newbie to Rancher/Docker/K8) and there are several issues I've found but not sure if they are inter-related or how to dig deeper.
- When restarting the rancher/rancher container, the mapped ports appear for about 90 seconds and then disappear and are no longer mapped. The container appears to be in a continuous restart loop.
- When looking at the logs for the rancher container, there is a error about an expired certificate but I can't find anything on how to regenerate the cert outside of the Rancher UI.
Here is the error message from the rancher container logs:
starting tls server: Get https://localhost:6444/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions: x509: certificate has expired or is not yet valid
Anybody have any ideas of where I can start to get answers on how to resolve this issue? This is a production environment and I need to get the UI working again so I can continue with my reverse engineering of the workloads, etc.
