Security certificate lifetime
MicroShift certificates are digital certificates that secure communication with communication protocols such as HTTPS. They fall into two basic categories:
- Short-lived certificates
-
Valid for one year. Most server or leaf certificates are short-lived.
- Long-lived certificates
-
Valid for 10 years. For example, the client certificate for
system:adminuser authentication, or thekube-apiserverexternal serving certificate signer.
MicroShift restarts automatically depending on certificate age.
