This is an express.js application that has no purpose but being a demo for other more significant projects.
The app doesn't have to be configured much for installation. The most important things will be
in Dockerfile and .env.
Building the docker image is straight forward enough. Just follow these easy steps:
- Configure your environment variables
- Execute the
docker build -t <image-name> .command - Run the container with
docker run --name=<container-name> -p <port:port> <image-name>
You could run the container with -d to run it in detached mode.
I am using Postgresql for this demo. You can use whatever you like. It's up to you. :)
In my case I am running Postgres as a separate container.
docker run --name=<container-name> -e <env vars> -p <port:port> postgres:latest
You might want to run it in a network since you'll need a way to access the postgres database anyway.
To create a docker network you have to run this command
docker network create <network-name>
To check if you created it you can run
docker network ls
Now you need to add your Postgres database container to this local network as well as the express app container.
docker network connect <network-name> <container-name>
