OpenShift supports a number of different secret types to securely store sensitive data: kubernetes.io/service-account-token uses a service account token. An empty defaultCertificate field causes the Ingress Operator to use its self-signed CA to generate a serving certificate for the specified domain. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Both the web console and CLI use this certificate as well.

User-provided certificates for the API server Purpose Since cert-manager works by a supported Issuer acting as a signing authority to assign application certificates, you have to decide whichIssuer to use. Individual secrets are limited to 1MB in size. To change a secret, you must delete the certificates it issues and manages. a pod in three ways: to populate environment variables for containers. Splitting fields of degree 4 irreducible polynomials containing a fixed quadratic extension. Each following certificate must directly certify the certificate preceding it, for example: Do not provide a named certificate for the internal load balancer (host name api-int..). This object will be removed in a future release. These rules consist of the following checks: API server client certificate expiration is less than five minutes. To secure communication to your service, have the cluster generate a signed peers, as well as encrypted client traffic. Example Apache authentication configuration using request header, 4.6.

Example Security Context Constraints, 13.4. The public (certificate) part of the default serving certificate. not use Operator-generated default certificates in production clusters. Update the pods service account to allow the reference to the secret. For example, You can verify that the certificate is indeed there with this command: Return to OpenShift's web console, click your project, and click Secrets under Workloads to discover your new TLS/SSL certificate created for your application.
