Out of the 10 or 20 posts about Docker that made it to front-page on HN in the last year, this is the first one that has been able to show me what Docker is.
Though I'm still confused on -
Real world examples of tried and proven setups like an environment of Apache, PHP, and MySQL being run inside a Docker container (for example: for setting up shared hosting on a box). Would that even make sense?
- BHSPitMonkey 13y agoMy understanding is that keeping your database in a separate container from your application(s) is a more preferred topology. In theory, you could easily spin up/spin down application containers as needed, and they can use Docker's service discovery features to automatically become aware of which port the database is listening on.
- alco 13y agoAt first, I was confused too. So I asked on the ML. See [1] and continuation in [2]. You could also browse the docker-user list, there are a number of threads asking to clarify various concepts about Docker.
