Remmina in Docker optimized for Unraid

Remmina is a remote desktop client for POSIX-based computer operating systems. It supports the Remote Desktop Protocol, VNC, NX, XDMCP, SPICE and SSH protocols.

With this container you can connect through VNC to your RDP session, SSH,...

At the bottom is an example how to reverse proxy noVNC with nginx and secure it via http basic authentification.

Env params

Name	Value	Example
DATA_DIR	Folder for gamefile	/remmina
CUSTOM_RES_W	Your preferred screen width	1280
CUSTOM_RES_H	Your preferred screen height	1024
UID	User Identifier	99
GID	Group Identifier	100
UMASK	User file permission mask for newly created files	000
DATA_PERM	Data permissions for main storage folder	770

Run example

docker run --name Remmina -d \
    -p 8080:8080 \
    --env 'CUSTOM_RES_W=1280' \
    --env 'CUSTOM_RES_H=1024' \
	--env 'UID=99' \
	--env 'GID=100' \
    --env 'UMASK=000' \
    --env 'DATA_PERM=770' \
	--volume /mnt/user/appdata/remmina:/remmina \
    --restart=unless-stopped\

Webgui address: http://[SERVERIP]:[PORT]/vnc.html?autoconnect=true

Reverse Proxy with nginx example:

server {
	listen 443 ssl;

	include /config/nginx/ssl.conf;
	include /config/nginx/error.conf;

	server_name rdp.example.com;

	location /websockify {
		auth_basic           example.com;
		auth_basic_user_file /config/nginx/.htpasswd;
		proxy_http_version 1.1;
		proxy_pass http://192.168.1.1:8080/;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "upgrade";

		# VNC connection timeout
		proxy_read_timeout 61s;

		# Disable cache
		proxy_buffering off;
	}
		location / {
		rewrite ^/$ https://rdp.example.com/vnc.html?autoconnect=true redirect;
		auth_basic           example.com;
		auth_basic_user_file /config/nginx/.htpasswd;
		proxy_redirect     off;
		proxy_set_header Range $http_range;
		proxy_set_header If-Range $http_if_range;
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header Host $host;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "upgrade";
		proxy_pass http://192.168.1.1:8080/;
	}
}

ATTENTION: Please edit the hostname, with the subdomain, and the IP to your corresponding settings!

Set VNC Password:

Please be sure to create the password first inside the container, to do that open up a console from the container (Unraid: In the Docker tab click on the container icon and on 'Console' then type in the following):

1. su $USER
2. vncpasswd
3. ENTER YOUR PASSWORD TWO TIMES AND PRESS ENTER AND SAY NO WHEN IT ASKS FOR VIEW ACCESS

Unraid: close the console, edit the template and create a variable with the Key: TURBOVNC_PARAMS and leave the Value empty, click Add and Apply.

All other platforms running Docker: create a environment variable TURBOVNC_PARAMS that is empty or simply leave it empty:

    --env 'TURBOVNC_PARAMS='

This Docker was mainly edited for better use with Unraid, if you don't use Unraid you should definitely try it!
