Docker stack configs for our Docker swarm clusters

Usage

1. On manager node - Create docker swarm cluster (if needed).

   docker swarm init

2. On worker nodes - Join the cluster (if needed).

   docker swarm join --token <token> <ip>:<port>

   Get the token if needed, by running docker swarm join-token worker

3. On all nodes - Add labels to the nodes in the cluster.

   [!IMPORTANT] Labels are used for placement constraints in the docker stack templates.

   Here are some example lables for the nodes. Adjust as needed

   • Get the node ids using docker node ls on the manager node.

   • On the manager node

     docker node update --label-add "portainer=true" <node id>

   • On the worker nodes

     JAMStack news

     docker node update --label-add "jms.enabled=true" <node id>

     docker node update --label-add "jms.variant=dev" <node id>
     docker node update --label-add "jms.variant=org" <node id>

     API

     docker node update --label-add "api.enabled=true" <node id>

     docker node update --label-add "api.variant=dev" <node id>
     docker node update --label-add "api.variant=org" <node id>

4. Deploy Portainer.

   [!WARNING]

   Copy the stack defined in portainer.yml to the manager node and deploy it.

   docker stack deploy -c portainer.yml portainer

5. Complete the Portainer setup wizard & add the cluster to Portainer.

6. Add the container registry details to Portainer.

7. Deploy all the remaining stacks via Portainer. Note that you should not manage the portainer stack from within Portainer UI.
