Kubectl password rotation policies

Kubectl password rotation policies protect Kubernetes from credential drift, stale secrets, and unauthorized access. Without rotation, old passwords or tokens remain valid long after they should be revoked. This creates a silent attack surface inside your infrastructure.

A strong password rotation policy for kubectl enforces regular updates to kubeconfig credentials, automates secret lifecycle management, and ensures every API request is gated by current authentication tokens. Kubernetes itself does not rotate passwords by default. You must define the rules, schedule, and automation.

Key Principles for Kubectl Password Rotation

1. Short-lived credentials – Set expiration times so access ends automatically.
2. Automated rotation scripts – Use CI/CD pipelines or Kubernetes Operators to regenerate and distribute credentials.
3. Immediate revocation – Terminate compromised credentials instantly through your identity provider.
4. Audit logging – Track all credential updates and kubectl authentication attempts for compliance and incident response.
5. Integration points – Connect rotation to Kubernetes RBAC, external vaults, and cloud IAM systems for central control.

Implementing Rotation Policies

• Configure kubeconfig files with temporary tokens rather than static passwords.
• Manage credentials via Kubernetes Secrets and integrate with tools like HashiCorp Vault or AWS Secrets Manager.
• Use a cron job or pipeline trigger to update credentials on a fixed schedule, such as every 24 hours or weekly depending on risk tolerance.
• Validate rotation through automated tests that confirm old credentials fail and new ones authenticate successfully with kubectl.

Security and Compliance

Password rotation policies are more than hygiene. They meet compliance requirements like PCI DSS, HIPAA, and ISO 27001. They also reduce dwell time for attackers by invalidating compromised access before it can be used.

Best Practices Checklist

• Rotate all kubectl credentials at least once per rotation period
• Store credentials securely and never check kubeconfig into source control
• Automate both generation and distribution to avoid manual error
• Audit and monitor every rotation event

Never trust static access keys. Build a culture of rotation, automation, and enforcement. The cost of neglect is higher than the cost of implementation.
