This is how I've been describing docker to people and also how I've been using it. It's why, when I need a specific version of elastic search or Postgres i just run the tagged service.
It turns any binary into a more portable executable.
Oops, I meant tagged images. If you look at the common images for like postgres, redis, and elasticsearch, they tag the images with the version of the service that's installed.
It turns any binary into a more portable executable.
Great post!
