This Image/Dockerfile aims to create a container for Ubuntu 18.04 with MATE Desktop and using TightVNCServer, noVNC, Ngrok(Optional) which allow user use browser to log in into this container.

You can build this Dockerfile yourself:

sudo docker build -t corruptedbuffer/ubuntu-novnc .

Or, just pull my image:

docker pull corruptedbuffer/ubuntu-novnc

The default usage of this image is:

docker run -itd -p 80:6080 corruptedbuffer/ubuntu-novnc

Wait for a few second, you can access http://localhost/vnc.html and see this screen:

In default, the password will create randomly, to find the password, please using the following command:

sudo docker exec $CONTAINER_ID cat /home/ubuntu/password.txt

And you can use this password to log in into this container.

After log in, you can see this screen:

This image contains 3 input argument:

1. Password

   You can set your own user password as you like:

   sudo docker run -itd -p 80:6080 -e PASSWORD=$YOUR_PASSWORD corruptedbuffer/ubuntu-novnc
   

   Now, you can user your own password to log in.

2. Sudo

   In default, the user ubuntu will not be the sudoer, but if you need, you can use this command:

   sudo docker run -itd -p 80:6080 -e SUDO=yes corruptedbuffer/ubuntu-novnc
   

   This command will grant the sudo to user ubuntu.

   And use SUDO=YES, SUDO=Yes, SUDO=Y, SUDO=y are also supported.

   To check the sudo is work , when you open MATE Terminal it should show following message:

   To run a command as administrator (user "root"), use "sudo <command>".
   See "man sudo_root" for details.
   

   

   Caution!! allow your user as sudoer may cause security issues, use it carefully.

   Ngrok can be used to deploy localhost to the internet.

   If you need to use this image across the internet, Ngrok is what you need.

   To enable Ngrok, use following command:

   sudo docker run -itd -p 80:6080 -e NGROK=yes corruptedbuffer/ubuntu-novnc
   

   And find the link address:

   sudo docker exec $CONTAINER_ID cat /home/ubuntu/ngrok/Ngrok_URL.txt
   

   NGROK=YES, NGROK=Yes, NGROK=Y, NGROK=y are also supported.

   Caution!! this may also cause security issues, use it carefully.
