Demonstrating CI-CD Pipeline using Jenkins, Docker Swarm Mode and Virtualbox running on Docker for Mac

Pre-requisite:

Ensure that Docker for Mac is installed
Ensure that Virtualbox is installed
Download https://gist.github.com/ajeetraina/11d38a790db147d6c2b519a460fe357d script and change the name it to swarm-script.sh

Execute the script

$chmod +x swarm-script.sh
$./swarm-script.h

Verify the Cluster

Do check if 3 node Swarm Mode cluster is up and running using the below command:

[Captains-Bay]🚩 >  sudo docker-machine ls

node02   -        virtualbox   Running   tcp://192.168.99.102:2376           v18.02.0-ce

Installing Jenkins on the Manager node

docker service create --mode=global --name jenkins-swarm-agent -e LABELS=docker-test --mount "type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock" --mount "type=bind,source=/tmp/,target=/tmp/" --secret source=jenkins-v1,target=jenkins vipconsult/jenkins-swarm-agent
