Compose Based Deployment

Here we'll deploy our pipeline in the Docker Container using compose.

Pre-requisites:

• Jenkins Server for running pipelines
• Hashicorp Vault for storing secrets
• Docker Swarm (This could be your localhost as well)
• 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 and Vault Cli

chmod +x ./scripts/setup.sh
./scripts/setup.sh

• Install and Start Jenkins Service

chmod +x ./scripts/jenkins_init.sh
./scripts/jenkins_init.sh

• Install recommended plugins and restart Jenkins

sudo systemctl restart jenkins

• Configure Jenkins Credentials for Private Registry

  • Update the Registry Credentials in Jenkins:

    Dashboard > RCW > deploy-staging > Credentials > docker-server

    Update with http://localhost:80, also create new credentials for registry username and password**

• Now run the compose file to deploy Registry, Nginx and Vault

docker compose up -d

• Start RCW Services

  • Run the script to init the vault & generate unseal tokens

  make start

  Note: This will store the registry username & password (admin/admin) inside the vault

  • Run the script to get registry username and password from vault

  chmod +x ./scripts/get_secrets.sh
  ./scripts/get_secrets.sh

• 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

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/
