Hereinafter, the term certificate.pem will be used to the full certificate chain.

  1. Copy the certificate.pem file onto a Linux computer and execute the command:

    cat certificate.pem | base64 -w0 > certificate.base64

     

  2. Use the contents of the newly created certificate.base64 file to replace the old value of the key crtFullChain in your values.yaml.

    global: ... cert: crtFullChain: "<replace here>" key: "<CERT-KEY-BASE64>" # <- do NOT change!

  4. Redeploy with the updated values.yaml.
