HTTPS Certificates

Installation and verification of SSL certificates

Configuration of ESB3024 AgileTV CDN Director is done through a REST API over HTTPS. While the router installer generates a self-signed certificate in order to enable the interface at all, this is not considered safe and secure so a properly generated certificate should be used instead.

For SSL to work, the router needs to have both an x509 certificate and a key in ASCII armored PEM format:

-----BEGIN PRIVATE KEY-----
[...]
-----END PRIVATE KEY-----

-----BEGIN CERTIFICATE-----
[...]
-----END CERTIFICATE-----

The files can be either separate .crt and .key files or a combined .pem file.

Simply copy the file(s) generated by your CA service, into the /opt/edgeware/acd/ssl folder on the host machine and they will automatically be used by the Director. Several key/crt pairs can be placed in the folder in order to support more than one domain name.

Wildcard certificates are supported, so a single certificate can be used for multiple subdomains.

Grafana

Adding HTTPS protection to Grafana is simple. The following ESB3024 Router-specific instructions are based on the official Grafana documentation.

First copy the .crt and .key files to the Grafana container. This will copy the files into /opt/edgeware/acd/grafana/etc/ but going through podman like this will ensure the correct ownership of the files so the Grafana process can properly use them:

podman cp <certificate> grafana:/etc/grafana/
podman cp <key> grafana:/etc/grafana/

Then edit /opt/edgeware/acd/grafana/etc/grafana.ini to enable SSL. Find the [server] section and set the following values, string values should have no quotation marks:

  • protocol to https
  • cert_file to /etc/grafana/<certificate>
  • cert_key to /etc/grafana/<key>

If any of the specified values have a semicolon (;) before the name, remove that character or the setting won’t take.

Finally restart the Grafana container:

systemctl restart acd-grafana

Now load up the Grafana web interface at https://<router hostname>:3000 and verify that SSL is active.
