r/node on Reddit: What's the win in dockerizing a node app?

May 1, 2018 -

A couple of recent posts here have been all about starting the process of dockerizing/containerizing node applications, which inspired me to play around a bit with Docker yesterday.

So, it seems like sticking a node app in docker is pretty straightforward as long as you can follow the Dockerfile templates online. But what you seem to get is a process running in a container that does the same thing as if you had just typed npm start from your development computer.

Then there's whatever else your node app depends on which really gets into the weeds. You can create a docker-compose file which launches your local app along with a dockerized database, but there are a lot of articles arguing against dockerized databases, at least in production.

It does seem like docker files would help do automated testing in something like CI/CD, but those tools add a ton of configuration to projects. It doesn't seem like docker makes deployment to production much easier without incorporating some CI/CD tool.

Is docker most useful for large teams/corporate settings? I'm developing an app solo, and maybe that's why I don't see the win.

Anyways, online communities seem to love Docker, so I figure I'm just not understanding, yet, what problems it solves. Can anyone help me understand what I'm missing?

Here’s a big win for me ; no more “well, it worked on my machine”. You’re always certain what environment your application will be runnjng in.

docker lets you namespace your application. So you get easier multi-tenancy, ie running multiple applications on the same system. For eg: if your app relies on node 0.10 and another on 9.8, it is quite hard to get both working together (nvm might work, but such tools are not really meant for production) yes, if you switch to docker, you need to make changes to your app hosting infrastructure. docker also makes testing easier, atleast in CI environments You don't have to switch - just like any other tool you need to evaluate and decide if the benefits it provides are worth it.
