8.2. Security certificate lifetime

MicroShift certificates are separated into two basic groups:

  1. Short-lived certificates having certificate validity of one year.
  2. Long-lived certificates having certificate validity of 10 years.

Most server or leaf certificates are short-lived.

An example of a long-lived certificate is the client certificate for system:admin user authentication, or the certificate of the signer of the kube-apiserver external serving certificate.

8.2.1. Certificate rotation
リンクのコピー

Certificates that are expired or close to their expiration dates need to be rotated to ensure continued MicroShift operation. When MicroShift restarts for any reason, certificates that are close to expiring are rotated. A certificate that is set to expire imminently, or has expired, can cause an automatic MicroShift restart to perform a rotation.

重要

If the rotated certificate is a MicroShift certificate authority (CA), then all of the signed certificates rotate. If you created any custom CAs, ensure the CAs manually rotate.

8.2.1.1. Short-term certificates
リンクのコピー

The following situations describe MicroShift actions during short-term certificate lifetimes:

  1. No rotation:

    1. When a short-term certificate is up to 5 months old, no rotation occurs.

  2. Rotation at restart:

    1. When a short-term certificate is 5 to 8 months old, it is rotated when MicroShift starts or restarts.

  3. Automatic restart for rotation:

    1. When a short-term certificate is more than 8 months old, MicroShift can automatically restart to rotate and apply a new certificate.

8.2.1.2. Long-term certificates

The following situations describe MicroShift actions during long-term certificate lifetimes:

  1. No rotation:

    1. When a long-term certificate is up to 8.5 years old, no rotation occurs.

  2. Rotation at restart:

    1. When a long-term certificate is 8.5 to 9 years old, it is rotated when MicroShift starts or restarts.

  3. Automatic restart for rotation:

    1. When a long-term certificate is more than 9 years old, MicroShift might automatically restart so that it can rotate and apply a new certificate.
