When you create an ingress within Rancher/Kubernetes, you must provide it with a secret that includes a TLS private key and certificate, which are used to encrypt and decrypt communications that come through the ingress. You can make certificates available for ingress use by adding the certificate to the ingress deployment.

Prerequisites: You must have a TLS private key and certificate available to upload.

1. Create a Secret

  1. In the upper left corner, click ☰ > Cluster Management.
  2. Go to the cluster where you want to deploy your ingress and click More Resources > Core > Secrets.
  3. Click Create.
  4. Click TLS Certificate.
  5. Enter a name for the secret. Note: Your secret must have a unique name among the other certificates, registries, and secrets within your project/workspace.
  6. In the Private Key field, either copy and paste your certificate’s private key into the text box (include the header and footer), or click Read from a file to browse to the private key on your file system. If possible, we recommend using Read from a file to reduce likelihood of error. Note: Private key files end with an extension of .key.
  7. In the Certificate field, either copy and paste your certificate into the text box (include the header and footer), or click Read from a file to browse to the certificate on your file system. If possible, we recommend using Read from a file to reduce likelihood of error. Note: Certificate files end with an extension of .crt.
  8. Click Create.

2. Add the Secret to an Ingress

  1. In the upper left corner, click ☰ > Cluster Management.
  2. Go to the cluster where you want to deploy your ingress and click Service Discovery > Ingresses.
  3. Click Create.
  4. Select the Namespace of the ingress.
  5. Enter a Name for the ingress.
  6. In the Certificates tab, select the secret containing your certificate and private key.
  7. Click Create.

What’s Next?

Now you can add the certificate when launching an ingress within the current project or namespace. For more information, see Adding Ingress.
