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 use case.

​
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

You 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.
