Get started with Score


If you’re new to Score, we recommend starting with the score-compose reference implementation. It provides a helpful blueprint for using Score and allows you to become familiar with the Score specification before exploring further implementation options.

Hello world with score-compose

1. To begin, follow the installation instructions to install the latest version of score-compose.

2. Open your IDE and paste in the following score.yaml file, which describes a simple service based on a busybox Docker image:


  name: hello-world

    image: busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo Hello World!; sleep 5; done"]

3. To convert the score.yaml file into runnable compose.yaml, run the following commands in your terminal:

$ score-compose init
$ score-compose generate score.yaml

The init will create the .score-compose directory. The generate command will add the input score.yaml workload to the .score-compose/state.yaml state file and regenerate the output compose.yaml.

$ cat compose.yaml
name: 01-hello
            - -c
            - while true; do echo Hello World!; sleep 5; done
            - /bin/sh
        image: busybox

If you make any modifications to the score.yaml file, run score-compose generate score.yaml to regenerate the output.

4. Run docker compose up to execute the newly generated compose.yaml file:

$ docker compose up -d
[+] Running 1/2
 ⠼ Network 01-hello_default                Created
 ✔ Container 01-hello-hello-world-hello-1  Started
$ docker logs -f 01-hello-hello-world-hello-1
Hello World!
Hello World!
Hello World!
Hello World!
$ docker compose down

Congrats! You’ve successfully run your first Score Implementation with a Hello World workload and provisioned it through Docker.
