SwarmOps

Docker Swarm Real-Time Monitoring

Requirements

• a Docker Swarm with managers & workers nodes

1/ Clone swarmops repository

• on a manager node :

git clone https://github.com/cdelaitre/swarmops.git
cd swarmops

2/ Configure

• Swarmops web
  • On your manager node, edit swarmops-web.yml and set constraint node.hostname with your manager hostname :

vim swarmops-web.yml

...
        constraints:
          - node.role == manager
          - node.hostname == <YOUR_MANAGER_HOSTNAME>
...

• Swarmops cluster
  • On your manager node, edit src/config.js and set swarmopsCluster with LAN IP of your nodes :

vim src/config.js

...
// - swarmopsCluster : array of lan ip nodes
var swarmopsCluster = ["192.168.0.34", "192.168.0.43", "192.168.0.44", "192.168.0.45", "192.168.0.46"];
...

3/ Deploy

• Swarmops netdata component
  • on each node, run command (cf 10-swarmops-netdata-deploy.sh) :

docker run -d \
  --cap-add SYS_PTRACE \
  --restart=always \
  -v /proc:/host/proc:ro \
  -v /sys:/host/sys:ro \
  -p 19999:19999 \
  --name swarmops-netdata \
  titpetric/netdata

• Swarmops web component
  • on your manager node, run command (cf 20-swarmops-web-deploy.sh) :

docker stack deploy --compose-file swarmops-web.yml swarmops

4/ Monitor

• Go to http://<LAN_IP_NODE>:19998
