https://www.docker.com/what-docker Another new thing to explore for the adventurer out there. This HUGO journey is taking me all over the world of cyberspace. There's GIT, then firebase and now docker. Just so many options. So much to read. So much to explore. And putting the puzzles together is almost like solving a jigsaw puzzle after losing the main picture But thanks to the more experienced people here at x10, the journey is more enjoyable.
