WebUI Access on Private Networks¶
If you are installing EWC on a host you do not have direct (or VPN) network access to (such as an AWS instance with only private IP addresses), you may have some difficulty connecting to the Web UI.
Simply creating an SSH tunnel through a bastion host, and then using a URL on localhost, such
as https://localhost:8443/ will fail. You will see an error message such as
Unable to reach auth
This is due to the way the Web UI authentication works, where the browser will be provided with URLs for the authentication service that do not map to your tunnel address.
If you do not have the ability to set up a VPN between your networks, the simplest solution is to
use SSH as a proxy, rather than creating tunnels. Use a command like
ssh -N -D 7654 bastion_host.
This command, using
-N, will not yield a command prompt.
Then configure your browser to use
localhost:7654 as a SOCKS5 proxy. You should then be able to
connect to your EWC Web UI using the private IP address, which will be proxied through your SSH
session, and it should Just Work.
