Stacks on Stacks of Docker Swarmzzz

Goal:

  • Migrate my plethora of Docker Containers w/Docker SWARRRRRRM

Lessons Learned:

  • Set up Swarm cluster w/manager & worker nodes
  • Test cluster

Initialize the SWARRRM:

  • Connect w/command:
    • SSH into public IP address
  • Begin to conduct swarm w/command:
    • Perform docker swarm init \
  • Establish private IP address w/command:
    • –advertise-addr
  • BOOOOM, now your an assistant-to-the-regional-manager!
  • Now you receive a command to place in your worker node, you did create a worker node…right?
  • Once your worker node is connected, quick see your list of nodes w/command:
    • docker node ls
  • Now create Ngninx service for the swarm w/the command above
    • (see above for the 4 lines of code)
  • To quick see your list of services w/the command:
    • docker service ls

Add Worker to Cluster:

  • Connect w/command:
    • SSH into public IP address
  • Add worker node to manager node w/command seen below
    • (see below for lengthy command)
