Tags

danielguerra/ubuntu-xrdp:16.04 danielguerra/ubuntu-xrdp:18.04 or latest danielguerra/ubuntu-xrdp:20.04 danielguerra/ubuntu-xrdp:clean (for development)

and a debian version kali linux (experiment) danielguerra/ubuntu-xrdp:kali

Usage

Start the rdp server (WARNING: use the --shm-size 1g or firefox/chrome will crash)

docker run -d --name uxrdp --hostname terminalserver --shm-size 1g -p 3389:3389 -p 2222:22 danielguerra/ubuntu-xrdp:20.04

*note if you already use a rdp server on 3389 change -p :3389 -p 2222:22 is for ssh access ( ssh -p 2222 ubuntu@ )

Connect with your remote desktop client to the docker server. Use the Xorg session (leave as it is), user and pass.

Creation of users

To automate the creation of users, supply a file users.list in the /etc directory of the container. The format is as follows:

id username password-hash list-of-supplemental-groups

The provided users.list file will create a sample user with sudo rights

Username: ubuntu Password: ubuntu

To generate the password hash use the following line

openssl passwd -1 'newpassword'

Run the xrdp container with your file

docker run -d -v $PWD/users.list:/etc/users.list

You can change your password in the rdp session in a terminal

passwd

Add new users

No configuration is needed for new users just do

docker exec -ti uxrdp adduser mynewuser

After this the new user can login

Add new services

To make sure all processes are working supervisor is installed. The location for services to start is /etc/supervisor/conf.d

Example: Add mysql as a service

apt-get -yy install mysql-server
echo "[program:mysqld] \
command= /usr/sbin/mysqld \
user=mysql \
autorestart=true \
priority=100" > /etc/supervisor/conf.d/mysql.conf
supervisorctl update

Volumes

This image uses two volumes:

  1. /etc/ssh/ holds the sshd host keys and config
  2. /home/ holds the ubuntu/ default user home directory

When bind-mounting /home/, make sure it contains a folder ubuntu/ with proper permission, otherwise no login will be possible.

mkdir -p ubuntu
chown 999:999 ubuntu

Installing additional packages during build

The Dockerfile has support for the build argument ADDITIONAL_PACKAGES to install additional packages during build. Either pass it with --build-arg during docker build or add it as args in your docker-compose.override.yml and run docker-compose build.

To run with docker-compose

git clone https://github.com/danielguerra69/ubuntu-xrdp.git
cd ubuntu-xrdp/
vi docker-compose.override.yml # if you want to override any default value
docker-compose up -d
