rclonebrowser-docker

A repository for creating a docker container including RClone Browser with GUI interface, based on kapitainsky fork

Thank you for continue developing this awesome software :)

You can invite me a beer if you want ;)

This is a completely funcional Docker image with RClone Browser (kapytainsky fork).

Based on Alpine Linux, which provides a very small size.

Tested and working on Synology and QNAP, but should work on any x86_64 devices.

Thanks to @jlesage for a great base image for GUI apps.

Thanks to @romancin for the work that was done

Instructions:

Map any local port to 5800 for web access
Map any local port to 5900 for VNC access
Map a local volume to /config (Stores configuration data)
Map a local volume to /media (Access media files)

Sample run command:

docker run -d --name=rclonebrowser \
-v /share/Container/rclonebrowser/config:/config \
-v /share/Container/rclonebrowser/media:/media \
-e GROUP_ID=0 -e USER_ID=0 -e TZ=Europe/Madrid \
-p 5800:5800 \
-p 5900:5900 \
ghcr.io/drmxrcy/rclonebrowser-docker:master

Browse to http://your-host-ip:5800 to access the RClone Browser GUI.

Environment Variables

To customize some properties of the container, the following environment variables can be passed via the -e parameter (one for each variable). Value of this parameter has the format <VARIABLE_NAME>=<VALUE>.

Variable	Description	Default
`USER_ID`	ID of the user the application runs as. See User/Group IDs to better understand when this should be set.	`1000`
`GROUP_ID`	ID of the group the application runs as. See User/Group IDs to better understand when this should be set.	`1000`
`SUP_GROUP_IDS`	Comma-separated list of supplementary group IDs of the application.	(unset)
`UMASK`	Mask that controls how file permissions are set for newly created files. The value of the mask is in octal notation. By default, this variable is not set and the default umask of `022` is used, meaning that newly created files are readable by everyone, but only writable by the owner. See the following online umask calculator: http://wintelguy.com/umask-calc.pl	(unset)
`TZ`	TimeZone of the container. Timezone can also be set by mapping `/etc/localtime` between the host and the container.	`Etc/UTC`
`KEEP_APP_RUNNING`	When set to `1`, the application will be automatically restarted if it crashes or if user quits it.	`0`
`APP_NICENESS`	Priority at which the application should run. A niceness value of -20 is the highest priority and 19 is the lowest priority. By default, niceness is not set, meaning that the default niceness of 0 is used. NOTE: A negative niceness (priority increase) requires additional permissions. In this case, the container should be run with the docker option `--cap-add=SYS_NICE`.	(unset)
`CLEAN_TMP_DIR`	When set to `1`, all files in the `/tmp` directory are delete during the container startup.	`1`
`DISPLAY_WIDTH`	Width (in pixels) of the application's window.	`1280`
`DISPLAY_HEIGHT`	Height (in pixels) of the application's window.	`768`
`SECURE_CONNECTION`	When set to `1`, an encrypted connection is used to access the application's GUI (either via web browser or VNC client). See the Security section for more details.	`0`
`VNC_PASSWORD`	Password needed to connect to the application's GUI. See the VNC Password section for more details.	(unset)
`X11VNC_EXTRA_OPTS`	Extra options to pass to the x11vnc server running in the Docker container. WARNING: For advanced users. Do not use unless you know what you are doing.	(unset)
`ENABLE_CJK_FONT`	When set to `1`, open source computer font `WenQuanYi Zen Hei` is installed. This font contains a large range of Chinese/Japanese/Korean characters.	`0`

Data Volumes

The following table describes data volumes used by the container. The mappings are set via the -v parameter. Each mapping is specified with the following format: <HOST_DIR>:<CONTAINER_DIR>[:PERMISSIONS].

Container path	Permissions	Description
`/config`	rw	This is where the application stores its configuration, log and any files needing persistency.
`/media`	rw	This is where downloaded files are stored, or where you put files in your host for uploading.

Ports

Here is the list of ports used by the container. They can be mapped to the host via the -p parameter (one per port mapping). Each mapping is defined in the following format: <HOST_PORT>:<CONTAINER_PORT>. The port number inside the container cannot be changed, but you are free to use any port on the host side.

Port	Mapping to host	Description
5800	Mandatory	Port used to access the application's GUI via the web interface.
5900	Optional	Port used to access the application's GUI via the VNC protocol. Optional if no VNC client is used.

User/Group IDs

When using data volumes (-v flags), permissions issues can occur between the host and the container. For example, the user within the container may not exists on the host. This could prevent the host from properly accessing files and folders on the shared volume.

To avoid any problem, you can specify the user the application should run as.

This is done by passing the user ID and group ID to the container via the USER_ID and GROUP_ID environment variables.

To find the right IDs to use, issue the following command on the host, with the user owning the data volume on the host:

id <username>

Which gives an output like this one:

uid=1000(myuser) gid=1000(myuser) groups=1000(myuser),4(adm),24(cdrom),27(sudo),46(plugdev),113(lpadmin)

The value of uid (user ID) and gid (group ID) are the ones that you should be given the container.

Security

By default, access to the application's GUI is done over an unencrypted connection (HTTP or VNC).

Secure connection can be enabled via the SECURE_CONNECTION environment variable. See the Environment Variables section for more details on how to set an environment variable.

When enabled, application's GUI is performed over an HTTPs connection when accessed with a browser. All HTTP accesses are automatically redirected to HTTPs.

When using a VNC client, the VNC connection is performed over SSL. Note that few VNC clients support this method. SSVNC is one of them.

Certificates

Here are the certificate files needed by the container. By default, when they are missing, self-signed certificates are generated and used. All files have PEM encoded, x509 certificates.

Container Path	Purpose	Content
`/config/certs/vnc-server.pem`	VNC connection encryption.	VNC server's private key and certificate, bundled with any root and intermediate certificates.
`/config/certs/web-privkey.pem`	HTTPs connection encryption.	Web server's private key.
`/config/certs/web-fullchain.pem`	HTTPs connection encryption.	Web server's certificate, bundled with any root and intermediate certificates.

NOTE: To prevent any certificate validity warnings/errors from the browser or VNC client, make sure to supply your own valid certificates.

NOTE: Certificate files are monitored and relevant daemons are automatically restarted when changes are detected.

VNC Password

To restrict access to your application, a password can be specified. This can be done via two methods:

By using the VNC_PASSWORD environment variable.
By creating a .vncpass_clear file at the root of the /config volume. This file should contains the password in clear-text. During the container startup, content of the file is obfuscated and moved to .vncpass.

The level of security provided by the VNC password depends on two things:

The type of communication channel (encrypted/unencrypted).
How secure access to the host is.

When using a VNC password, it is highly desirable to enable the secure connection to prevent sending the password in clear over an unencrypted channel.

ATTENTION: Password is limited to 8 characters. This limitation comes from the Remote Framebuffer Protocol RFC (see section 7.2.2). Any characters beyhond the limit are ignored.

Shell Access

To get shell access to a the running container, execute the following command:

docker exec -ti CONTAINER sh

Where CONTAINER is the ID or the name of the container used during its creation (e.g. crashplan-pro).

Reverse Proxy

The following sections contains NGINX configuration that need to be added in order to reverse proxy to this container.

A reverse proxy server can route HTTP requests based on the hostname or the URL path.

Routing Based on Hostname

In this scenario, each hostname is routed to a different application/container.

For example, let's say the reverse proxy server is running on the same machine as this container. The server would proxy all HTTP requests sent to rclonebrowser.domain.tld to the container at 127.0.0.1:5800.

Here are the relevant configuration elements that would be added to the NGINX configuration:

map $http_upgrade $connection_upgrade {
	default upgrade;
	''      close;
}

upstream rclonebrowser {
	# If the reverse proxy server is not running on the same machine as the
	# Docker container, use the IP of the Docker host here.
	# Make sure to adjust the port according to how port 5800 of the
	# container has been mapped on the host.
	server 127.0.0.1:5800;
}

server {
	[...]

	server_name rclonebrowser.domain.tld;

	location / {
	        proxy_pass http://rclonebrowser;
	}

	location /websockify {
		proxy_pass http://rclonebrowser;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection $connection_upgrade;
		proxy_read_timeout 86400;
	}
}

Routing Based on URL Path

In this scenario, the hostname is the same, but different URL paths are used to route to different applications/containers.

For example, let's say the reverse proxy server is running on the same machine as this container. The server would proxy all HTTP requests for server.domain.tld/rclonebrowser to the container at 127.0.0.1:5800.

Here are the relevant configuration elements that would be added to the NGINX configuration:

map $http_upgrade $connection_upgrade {
	default upgrade;
	''      close;
}

upstream rclonebrowser {
	# If the reverse proxy server is not running on the same machine as the
	# Docker container, use the IP of the Docker host here.
	# Make sure to adjust the port according to how port 5800 of the
	# container has been mapped on the host.
	server 127.0.0.1:5800;
}

server {
	[...]

	location = /rclonebrowser {return 301 $scheme://$http_host/rclonebrowser/;}
	location /rclonebrowser/ {
		proxy_pass http://rclonebrowser/;
		location /rclonebrowser/websockify {
			proxy_pass http://rclonebrowser/websockify/;
			proxy_http_version 1.1;
			proxy_set_header Upgrade $http_upgrade;
			proxy_set_header Connection $connection_upgrade;
			proxy_read_timeout 86400;
		}
	}
}
