Multiple old CA cert Files Observed on Host After Host CA Rotation

Problem

• Multiple copies of old/expired certificates of the Platform9 Management Plane continue to exist in /etc/pf9/certs/ca directory even after CA rotation.
• The same issue is faced for hostagent certificates as well that are present in the /etc/pf9/certs/hostagent/ directory.
• The Bouncer container logs that it is no longer able to establish a connection to Keystone to validate the authentication token, example below:

2023/11/30 18:46:12 authn with credentials: obtain project token from credentials: send keystone request: Post http://localhost:8158/keystone/v3/auth/tokens?nocatalog: EOF

Environment

• Platform9 Managed Kubernetes - v5.6.8 and Higher

Answer

• Platform9 is aware of this issue and is currently being tracked internally with JIRA - PMK-6262.
