You can integrate mutual TLS and ingress with third-party certificate authorities for certificate management. This enables secure service-to-service communication within a Space and user-to-service communication into a Space on Tanzu Platform.

Integrate the Vault certificate authority

To integrate the Vault CA:

1. In the Tanzu Platform UI, go to Spaces > Capabilities.
2. Click on the Capability Ingress.
3. Select the cluster group to which you want to install the Capability.

4. Select Advanced Configuration > YAML to enter Vault endpoint details.

   

   Sample Input for vault CA:

   # This vault section is considered for mTLS
   vault:
    # path: signing endpoint path. Here 'root' is fixed.
    path: pki/root/sign-intermediate
    # server: URL where vault CA is hosted
    server: https://vault.foo.com:8200/
    # caBundle: Required if server endpoint is with https
    caBundle: <base64 encoded ca bundle>
    # auth: Token/Secret for API access
    auth:
      token: <base64 encoded api access token>
   # This clusterIngressCa:vault section is considered for ingress TLS
   clusterIngressCa:
    vault:
      # path: signing endpoint path. Here 'sign' is fixed.
      path: ingress/sign/ingress-role
      # server: URL where vault CA is hosted
      server: https://vault.foo.com:8200/
      # caBundle: Required if server endpoint is with https
      caBundle: <base64 encoded ca bundle>  # Required if server endpoint is with https
      # auth: Token/Secret for API access
      auth:
        token: <base64 encoded api access token>
   

5. Click Install Package.

Integrate a Space-managed self-signed certificate

By default, a Space-managed self-signed certificate is considered for mTLS when the Ingress Capability is deployed without any CA credentials input. To integrate a Space-managed self-signed certificate:

1. In the Tanzu Platform UI, scroll down to Application Platform.
2. Go to Spaces > Capabilities.
3. Click on the Capability Ingress.
4. Select the cluster group to which you want to install the Capability.
5. Click Install Package.
