Deploying on Server

To get started with setting up the DevOps Pipeline.

Pre-requisites:

• Jenkins Server for running pipelines
• Hashicorp Vault for storing secrets
• Private Docker Registry
• Ansible for deploying swarm nodes

Setting up the Pipeline

• Clone the repository

git clone https://github.com/SamagraX-RCW/devops.git

• Run the scripts to install Docker & Ansible

chmod +x setup.sh
./setup.sh

• Install Jenkins

• Configure Vault token

  • Generate Unseal and Root token

• Intialize Swarm Managers and Workers

  • Add your manager and worker hosts in the host file

  • Run the playbook

  ansible-playbook -i ./ansible_workspace_dir/inventory/hosts ./ansible_workspace_dir/main.yml

• Configure Jenkins Credentials for Private Registry

  Go to

  Dashboard > RCW > deploy-staging > Credentials > docker-server > Update with https://nginx-reverse-proxy:80 -u <registry_username> -p <registry_password>, use port 443 if you are using SSL

• SSL Configuration for Nginx(Optional)

  • Copy the SSL certificates and paste it inside the nginx_config/ssl folder

  • Now run the script

    chmod +x ./scripts/set_up_ssl.sh
    ./scripts/set_up_ssl.sh

  • This script will store the ssl certs content inside the Vault as KV(key value) and keep as environment variable inside the Nginx container

• Now Jenkins will run ansible playbook after the build has been successful

Adding Ansible Roles for Services

• Run the Script

chmod +x /scripts/roles.sh
./scripts/roles.sh

• Give the name of the role

  eg. monitoring

• Now give the variables for that role

  eg. no. of replicas : 1/2/3
