I'm currently at my first job, working at a budding unicorn company in silicon valley. I've been here 1.75 years and am already in the midst of a 3rd rewrite - although not my decision (from higher ups)
The last paragraph really hits home for me and i've 100% gotten very jaded and very very bitter.
Ahh that's true, I guess what I was getting at was that it makes the deploys much quicker and easier (at least in my experience).
I was also playing around with a chat command to spin up PR's/branches that haven't been merged into master yet, onto a temp container for viewing! Dunno, maybe i'm just not as familiar with other tools that can do similar things as easily
Here's a really simple example of a project that I had set up using docker.
For my website I have it set up with continuous integration to run my tests when I merge into master and build a docker image which it then pushes to the docker registry. I then have it ssh into my host server, pull that image, then run the new container and remove the old one.
Boom, i've just deployed my website by simply merging a PR into my master!
This is just a simple use case, and I probably wouldn't suggest deploying a production ready site like this, but it's really cool! It's really simple to just pass around images and have things up and running on local dev's too
