I think you are looking for certmonger, but it will require some manual steps: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm...

However, in practice, there is a security risk related to the above certificates. That is, you need to generate a new certificate after the certificate expires. Otherwise, a problem will occur. In addition, different certificates expire at different times, which brings a lot of management trouble to users. Especially in the production system, a huge virtualization cluster may run thousands of VMS. If a cluster certificate has a problem, the impact is very serious. So I felt there was an urgent need for a technical tool that could help users quickly locate certificates, identify their expiration dates, and rebuild them. Even if there is no tool, there should be a way to solve the problems caused by partial certificate expiration. I think it should include the following points: First, how to list the certificate in detail Second, how to check the certificate expiration time Third, how to rebuild the certificate Does anyone else have this kind of confusion? What's a good solution?
