Internal service

An Internal service is a lot like Web service, but it is not exposed to public internet. It is available to get used from within the environment by other services.

Port

When you create a service, you must provide port number where your Dockerfile exposes the running code.

Number of replicas

For redundancy, ensure you set at least 2 as the number of replicas. This is a best practice yet you can enter 1 if it better suits your usecase.

No downtime deployments

All deployments are no-downtime deployments. When LocalOps deploys your code, it brings up new containers with new code first. If they become healthy, old containers will be stopped.

Logs

Yan can see logs of running containers via the in-built Grafana dashboard. Navigate to Monitor tab to login to Grafana dashboard. Within Grafana dashboard, filter to see app-services namespace logs.

You can create any number of internal services to suit your application architecture. All of the above will be applicable for each of them.
