1.)We need the bacon source code 4.6

1.b)download it ,uncompress it and cd into the folder

​

2.) copy the Docker file above into the bacon folder (you just cd into)

​

3.) docker build -t bacon-fltk .

​

4.) First check to see if bacon is working only

docker run bacon-fltk:latest bacon -v

​

5.) Build a fltk bacongui (official) full featured complete app

run the next command in your terminal to pass the X displays "magical code" to the docker image

xhost +local:

you should get this output in your terminal
non-network local connections being added to access control list

​

6.) lets simplify this long command to say $X2DOCKER

export X2DOCKER=" -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY bacon-fltk"

7.

docker run $X2DOCKER bacongui-fltk

now you can pass x to any app to test

if all went well you will see this
