Workers

A worker is lot like an internal service that runs continuously yet doesn't expose any service publicly or privately.

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 worker 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 worker services to suit your application architecture. All of the above will be applicable for each of them.
