Docker swarm UI: Swarmpit

Swarmpit provides simple and easy to use interface for Docker Swarm cluster. using swarmpit we can manage docker stacks, services, secrets, volumes, networks, docker nodes etc, swarm cluster we can manage through UI

Pre-requisites:

1. install docker on server
2. start the docker service

Steps to install swarmpit:

We deploy swarmpit stack file server using CLI

docker swarm init

git clone https://github.com/swarmpit/swarmpit -b master
docker stack deploy -c swarmpit/docker-compose.yml swarmpit

swarmpit runs on port 888, so open your browser http://<IP>:888

This stack file consists of mainly 4 things

• app — Swarmpit
• agent — Swarmpit agent
• db — CouchDB (Application data)
• influxdb — InfluxDB (Cluster statistics)

Couch DB contains users and stack files, configs, secrets, when we want to restore we need to take this backup, this is a docker volume located at /var/lib/docker/volumes

Deploying a stack file in swarmpit:

1. go to UI → Applications → stacks
2. create a new stack , here i am creating stack file for nginx

version: “3”

services:

nginx:

image: nginx

ports:

- 80:80

- 443:443

deploy:

mode: replicated

replicas: 3

restart_policy:

condition: on-failure

delay: 30s

max_attempts: 3

window: 120s

creating a stack file in swarmpitUI

after deploying stack, listing the service in UI

Listing the services running on node in CLI mode

open the port 80 and login to browser http://<IP>
