This document shows how to set up a local environment that runs ScalarDL along with the back-end Cassandra server using Docker Compose.

Prerequisites​

Clone scalardl-samples repository​

scalar-labs/scalardl-samples repository is a project for users to start working on ScalarDL instantly.

Determine the location on your local machine where you want to run the scalardl-samples app. Then open the terminal and cd to the directory and run the following commands:

git clone https://github.com/scalar-labs/scalardl-samples.git
cd scalardl-samples

Docker login​

docker login is required to start the ScalarDL Docker image. Because the scalar-ledger repository on GitHub Container Registry is currently private, your GitHub account needs to be set with permissions to access the container images. Ask a person in charge to get your account ready. Note also that you need to use a personal access token (PAT) as a password to login ghcr.io. Please read the official document for more detail.

# read:packages scope needs to be selected in a personal access token to login
export CR_PAT=YOUR_PERSONAL_ACCESS_TOKEN
echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin

Start up ScalarDL Ledger​

The following command starts up ScalarDL Ledger along with the back-end Cassandra server in the Docker containers. At the first time you run the command, the required Docker images will be downloaded from GitHub Container Registry.

docker-compose up

You may want to run the containers in the background. Add the -d (--detach) option:

docker-compose up -d

When you want to use Auditor component, run the following command.

docker-compose -f docker-compose.yml -f docker-compose-auditor.yml up -d

Shut down ScalarDL Ledger​

To shut down the containers:

  • If you started the containers in the foreground, type Ctrl+C in the terminal where docker-compose is running.
  • If you started the containers in the background, run the following command.
docker-compose down

# When Auditor is running
docker-compose -f docker-compose.yml -f docker-compose-auditor.yml down
