Deploying Your Cluster

After your configuration is complete and saved to file, you can deploy all services to your cluster:

1. Before starting, you can optionally open a separate terminal window to monitor services as they deploy to Docker. The command below refreshes every 2 seconds, but you can adjust the interval to your needs:

shell

Copy

$ watch -n 2 docker service ls

2. Execute the following command to deploy your saved configuration:

shell

Copy

$ dms cluster start

3. As the deployment executes, status messages will appear as each service is spun up. Here is a sample extract:

shell

Copy

Starting deployment...
🏁️ Deployment for service minio-api finished successfully
🏁️ Deployment for service song-db finished successfully
🏁️ Deployment for service gateway finished successfully
🏁️ Deployment for 'ego-db' finished
⏳ Waiting for 'elasticsearch' service to be healthy..
⏳ Waiting for 'ego-api' service to be healthy..
<...and so on...>

4. It may take some time for the deployment to exit successfully, as multiple services need to be deployed and the relatively larger services may take some time to complete (e.g. Ego API, Elasticsearch). Depending on your system resources, if the process takes too long and you encounter timeouts, there is a configurable timeout period (in seconds) and # of retries in the ~/.dms/config.yaml file, which you can adjust and retry deployment if necessary:

shell

Copy

healthCheck:
  retries: 15
  delaySec: 10

Once complete, a success message appears, including a note (with a link to documentation) reminding you to perform necessary post-deployment verification and configuration tasks to make sure the DMS platform is up and running healthily:

shell

Copy

Deployment completed successfully
