Docker and Digital Ocean servers are different things that can be used together.
Docker allows you to distribute applications that come bundled with their own OS-level packages/configuration.
Imagine you wanted to run Wordpress on your DO server. Instead of configuring a LAMP stack and setting up Wordpress on it, you could download and run a Wordpress docker container that came bundled with its own LAMP stack. It would be as simple for you as calling "docker run wordpress".Most importantly, its configuration would be completely isolated from that of the host machine.
- ninetax 13y agoBut that's not quite true is it? You would still have to open up ports on your host, configure security, and somehow do the meta-config for the dockerfile to make sure that if the host goes down, `docker run wordpress` is called on startup right? I really want to get excited about docker, but I guess I just don't understand it. Any links to more specific use cases?
