The following sections describe how to create re-encrypt and edge routes with custom certificates.

If you create routes in Microsoft Azure through public endpoints, the resource names are subject to restriction. You cannot create resources that use certain terms. For a list of terms that Azure restricts, see Resolve reserved resource name errors in the Azure documentation.

Creating a re-encrypt route with a custom certificate

You can configure a secure route using reencrypt TLS termination with a custom certificate by using the oc create route command.

Prerequisites
  • You must have a certificate/key pair in PEM-encoded files, where the certificate is valid for the route host.

  • You may have a separate CA certificate in a PEM-encoded file that completes the certificate chain.

  • You must have a separate destination CA certificate in a PEM-encoded file.

  • You must have a Service resource that you want to expose.

Password protected key files are not supported. To remove a passphrase from a key file, use the following command:

$ openssl rsa -in password_protected_tls.key -out tls.key
Procedure

This procedure creates a Route resource with a custom certificate and reencrypt TLS termination. The following assumes that the certificate/key pair are in the tls.crt and tls.key files in the current working directory. You must also specify a destination CA certificate to enable the Ingress Controller to trust the service’s certificate. You may also specify a CA certificate if needed to complete the certificate chain. Substitute the actual path names for tls.crt, tls.key, cacert.crt, and (optionally) ca.crt. Substitute the name of the Service resource that you want to expose for frontend. Substitute the appropriate host name for www.example.com.

  • Create a secure Route resource using reencrypt TLS termination and a custom certificate:

    $ oc create route reencrypt --service=frontend --cert=tls.crt --key=tls.key --dest-ca-cert=destca.crt --ca-cert=ca.crt --hostname=www.example.com

    If you examine the resulting Route resource, it should look similar to the following:

    YAML Definition of the Secure Route
    apiVersion: v1
    kind: Route
    metadata:
      name: frontend
    spec:
      host: www.example.com
      to:
        kind: Service
        name: frontend
      tls:
        termination: reencrypt
        key: |-
          -----BEGIN PRIVATE KEY-----
          [...]
          -----END PRIVATE KEY-----
        certificate: |-
          -----BEGIN CERTIFICATE-----
          [...]
          -----END CERTIFICATE-----
        caCertificate: |-
          -----BEGIN CERTIFICATE-----
          [...]
          -----END CERTIFICATE-----
        destinationCACertificate: |-
          -----BEGIN CERTIFICATE-----
          [...]
          -----END CERTIFICATE-----

    See oc create route reencrypt --help for more options.

Creating an edge route with a custom certificate

You can configure a secure route using edge TLS termination with a custom certificate by using the oc create route command. With an edge route, the Ingress Controller terminates TLS encryption before forwarding traffic to the destination Pod. The route specifies the TLS certificate and key that the Ingress Controller uses for the route.

Prerequisites
  • You must have a certificate/key pair in PEM-encoded files, where the certificate is valid for the route host.

  • You may have a separate CA certificate in a PEM-encoded file that completes the certificate chain.

  • You must have a Service resource that you want to expose.

Password protected key files are not supported. To remove a passphrase from a key file, use the following command:

$ openssl rsa -in password_protected_tls.key -out tls.key
Procedure

This procedure creates a Route resource with a custom certificate and edge TLS termination. The following assumes that the certificate/key pair are in the tls.crt and tls.key files in the current working directory. You may also specify a CA certificate if needed to complete the certificate chain. Substitute the actual path names for tls.crt, tls.key, and (optionally) ca.crt. Substitute the name of the Service resource that you want to expose for frontend. Substitute the appropriate host name for www.example.com.

  • Create a secure Route resource using edge TLS termination and a custom certificate.

    $ oc create route edge --service=frontend --cert=tls.crt --key=tls.key --ca-cert=ca.crt --hostname=www.example.com

    If you examine the resulting Route resource, it should look similar to the following:

    YAML Definition of the Secure Route
    apiVersion: v1
    kind: Route
    metadata:
      name: frontend
    spec:
      host: www.example.com
      to:
        kind: Service
        name: frontend
      tls:
        termination: edge
        key: |-
          -----BEGIN PRIVATE KEY-----
          [...]
          -----END PRIVATE KEY-----
        certificate: |-
          -----BEGIN CERTIFICATE-----
          [...]
          -----END CERTIFICATE-----
        caCertificate: |-
          -----BEGIN CERTIFICATE-----
          [...]
          -----END CERTIFICATE-----
