Migrating to the Reverse Tunnel

Migrating from Direct Connection to Reverse Tunnel

To migrate from a Sombra cluster using the legacy Direct Connection method to the Reverse Tunnel method, you can remove the load balancer and TLS infrastructure and then add a few new environment variables:

• Remove the external port opening in your firewall, and anywhere else where you mention the external port
• Remove the EXTERNAL_PORT_HTTP or EXTERNAL_PORT_HTTPS environment variables if you had them set
• Add a SOMBRA_REVERSE_TUNNEL_API_KEY environment variable and give it a value from the API Keys page in the Admin Dashboard
• Remove the load balancer for the external Sombra and all related configuration
