MAMS is deployed using Docker Swarm with multiple stacks and services.

​
Main MAMS Server

The main MAMS server (mams.devops.arabiaweather.com) runs the following stacks:

​
Stacks

  • modms: Main ModMS services (modms and connector)
  • mams-archive: Nginx service for serving archived data
  • ophelia: Ophelia-related services (modms, redis, updater)

​
Services

ModMS Stack:
  • modms_modms: Main ModMS API service (4 replicas, port 8081)
  • modms_connector: Connector service for remote queries (4 replicas, port 8082)
MAMS Archive Stack:
  • mams-archive_mams-local-archive: Nginx service for serving archived data (port 8083)

​
Archive Servers

Archive servers (e.g., Mams.04 at 138.201.49.117) run:

​
Stacks

  • modms: Connector service only
  • mams-archive: Nginx service for serving archived data

​
Services

  • modms_connector: Connector service (4 replicas, port 8082)
  • mams-archive_mams-archive: Nginx service (port 8083)
Archive servers only run the connector service, not the full ModMS API. This allows the main server to query data from archive servers.

​
Checking Deployment Status

To check the deployment status on any MAMS server: 
# SSH to the server
ssh Mams  # or ssh Mams.04 for archive server

# Switch to root
sudo su -

# List Docker stacks
docker stack ls

# List all services
docker service ls

# Check specific service status
docker service ps modms_connector
docker service ps modms_modms

# Check service logs
docker service logs modms_connector
docker service logs modms_modms
