# Add the PTGui config file and the activation ticket
#! First, comment the following lines, build the image `docker build -t docker-gui .` and run it, connect via VNC, run PTGui and activate with your license as usual, then copy the activation ticket file from /root/.PTGui/reg.dat outside the container and stop the container.
#! Save the activation ticket file next to this Dockerfile and prepend it with "*your machine hostname*_". Then un-comment the following lines and and rebuild the image with the name "docker-gui-reg".
#! This is to avoid manual activation whenever a new container is created by `docker run`. Do all this on the machine(s) you intend to use PTGui on since the activation ticket is not transferrable, and make sure to NOT exceed the number of machines your license is valid for.
