• During Jenkins installation, after copying the jobs chown the /var/lib/jenkins/jobs/ to jenkins user

• In the elastic search configuration, update the elastic search file as per your cluster needs

• In the Install Docker Compose section, run docker swarm init before issuing other commands

• When the Jenkins is up and ready to go, we have to take care of the following

• Update docker-server URL in Jenkins Jobs to pull and push images in build jobs

• Add ssh keys for your server from the Jenkins server before using ansible playbooks

• Add sudo to Jenkins deploy jobs commands in Configure Jobs section.

• Populate the environment variables for ansible-playbooks in Deploy jobs of Jenkins

• Update the Nginx conf files according to the services of your application

• Gotcha: React environment variables are pushed during the build, so runtime docker environment variables will not be picked up by React Apps. Therefore, configure the Dockerfiles accordingly and builds accordingly.
