Docker Development

Okay so I need a little help understanding something.

I have a few requirements for an app I'm working on.


  • MongoDB
  • Kotlin on graalVM

Now both of the above have images but how do I get them to smush together in an image of my own.

example of an image:

Do I just write my own docker file and ignore the official distributions?

Dockerfile should pull in files from the same folder by default, if not .dockerignore'd.

FROM oracle/graalvm-ce
CMD ["node", "index.js"]
Enter fullscreen mode Exit fullscreen mode

As to run MongoDB, I would create docker-compose.yml. Something like this.

So that's what docker compose is. Il go do some research.

Better off using docker compose or similar to have 2 separate images rather than combining the 2 services in one container - that gives you more control over scaling, eg just the DB or just the app part, and just generally makes it easier to keep track of what’s going on

Thanks Dan, I found that out a couple of hours ago whilst researching, its quite a lot easier than doing this manually.
I feel like Im an in an Alien world right now, great fun!
