How can I use Docker Compose for my Go applications?

You can use Docker Compose to define and run multi-container Docker applications. For a Go app, you'll typically create a docker-compose.yml file that specifies your Go service and any dependencies like databases.

What should I include in the docker-compose.yml file?

In your docker-compose.yml, you should define the version, services, and any environment variables. For example:

version: '3'
services:
  my-go-app:
    build: .
    ports:
      - "8080:8080"
    environment:
      - ENV_VAR=value

How do I build and run the containers?

You can build and run your containers using the command docker-compose up --build. This will build the images and start the containers defined in your docker-compose.yml.

Can I use Docker Compose for testing my Go app?

Yes, you can use Docker Compose to set up a testing environment. You can define a separate service in your docker-compose.yml for running tests, ensuring that all dependencies are available.
