NoVNC Proxy in Docker

[mchlrv]

I'm running webvirtcloud in Docker and use Apache to proxy pass traffic to webvirtcloud in docker.
Everything seems to work when using non SSL (http). However when I'm trying to use SSL (https) everything seems to work except NoVNC.

I'm not sure what I forget or do wrong as this works for non SSL. Any suggestions?

My Apache proxy part looks as follow:

ProxyRequests Off

ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/

ProxyPass /novncd/ ws://localhost:6080/novncd/ retry=3
ProxyPassReverse /novncd/ ws://locahost:6080/novncd/ retry=3

My webvirtcloud settings look like:

# Websock port
WS_PORT = 6080

# Websock host
WS_HOST = "0.0.0.0"

# Websock public port - 80 or 443 if reverse-proxy, else 6080
WS_PUBLIC_PORT = 443

# Websock public host
WS_PUBLIC_HOST = None

# Websock public path
WS_PUBLIC_PATH = "/novncd/"

When trying to connect to NoVNC and looking a the developer console the following error appears:

websock.js:185 WebSocket connection to 'wss://webvirtcloud:6080//novncd/' failed: Error in connection establishment: net::ERR_CONNECTION_RESET

This week I gave it another try after updating to the latest version. After some fiddling around I finally got it working. A bit more / better documentation would be helpful (this applies to multiple topics). Hopefully my results will help others with similar problems.

Webvirtcloud runs in docker and I'm using Apache as a reverse proxy. Below my Apache reverse proxy and websocket config.

RewriteEngine on
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "ws://localhost:6080/$1" [P,L]

ProxyPass /novncd/ ws://localhost:6080/novncd/ retry=3
ProxyPassReverse /novncd/ ws://locahost:6080/novncd/ retry=3

In settings.py I have configured below config for the websocket. Since I'm using SSL I've configured the WS_PUBLIC_PORT to use port 443. I also had to configure WS_PUBLIC_HOST which is the url through which Webvirtcoud is reachable.

# Websock port
WS_PORT = 6080

# Websock host
WS_HOST = "0.0.0.0"

# Websock public port - 80 or 443 if reverse-proxy, else 6080
WS_PUBLIC_PORT = 443

# Websock public host
WS_PUBLIC_HOST = "webvirtcloud.domain.tld"

# Websock public path
WS_PUBLIC_PATH = "novncd/"

Once this is all in place there is one more important step it take and that is to open up the firewall on the server running KVM. You need to open the VNC ports configured for the VM's otherwise NoVNCd can not connect.
