Docker Servers Status Script

Will connect to all your servers (in parallel) and report:

  • CPU and memory usage
  • Disk usage
  • If updates are available and if a reboot is required
  • Running Docker containers against a given list, noting missing and extras

Screenshot

Setup

You will need Ruby >3. I don't think you need any gems.

You need mpstat on your servers. It's part of the default Ubuntu install but not the AWS version. If you see "CPU: ???", run: sudo apt install sysstat

config.yml

Root keys are groups with arrays of servers.

For each server:

  • name : the name/hostname of the server
  • hostname : the hostname. Defaults to name
  • containers : a list of containers expected to run. Matched as start of running containers. E.g. myapp-staging will match running container myapp-staging-latest-123abc.
  • proxy : whether to expect kamal-proxy. Defaults to true
  • docker : whether to expect Docker running at all. Defaults to true
  • user : SSH user. Defaults to root
  • identity_file : path to SSH key
  • disks : a list of mount points to check for usage. Defaults to ["/"]

Example:

staging:
  - name: api.staging.myapp.com
    containers:
      - myapp-staging
  - name: db.staging.myapp.com
    containers:
      - myapp-postgres-staging
    proxy: false
  - name: Barebone Server 1
    hostname: 1.2.3.4
    docker: false
    user: ubuntu
    identity_file: ~/keys/barebone.pem
    disks:
      - "/"
      - "/mnt/data"
production:
# ...
