====== DevOps ======

===== Introduction =====

Welcome to the Unicis DevOps Handbook. This guide is designed to help you understand and manage the DevOps processes for the Unicis Platform, which is built on Platform-as-a-Service (PaaS) infrastructure using OVH Cloud and utilizes CapRover for Continuous Integration and Continuous Deployment (CI/CD).

===== Platform Overview =====

Unicis Platform is a robust solution designed to deliver a seamless PaaS experience. Our infrastructure is hosted on OVH Cloud, ensuring reliability and scalability. The CI/CD processes are streamlined using CapRover, a powerful, user-friendly deployment solution.

===== Infrastructure: OVH Cloud =====

OVH Cloud provides the backbone for our infrastructure. Here’s how we leverage OVH Cloud for our PaaS needs:

==== 1. OVH Cloud Setup ====

  * **Account Creation**: Create an account on the OVH Cloud platform.
  * **Project Setup**: Set up a new project in the OVH Cloud dashboard.
  * **Resource Allocation**: Allocate necessary resources (compute instances, storage, network configurations) based on project requirements.

==== 2. Network Configuration ====

  * **VPC Setup**: Create a Virtual Private Cloud (VPC) for secure networking.
  * **Subnets and Security Groups**: Define subnets and configure security groups to control inbound and outbound traffic.
  * **Load Balancers**: Set up load balancers to distribute traffic efficiently.

==== 3. Storage Solutions ====

  * **Object Storage**: Use OVH Cloud Object Storage for scalable and secure data storage.
  * **Block Storage**: Attach block storage volumes to instances as needed.

==== 4. Monitoring and Alerts ====

  * **Monitoring Tools**: Integrate monitoring tools (e.g., Grafana, Prometheus) to keep track of infrastructure health.
  * **Alerting Mechanisms**: Set up alerts for critical events and thresholds.

===== CI/CD: CapRover Solution =====

CapRover is our chosen solution for managing CI/CD processes due to its simplicity and powerful features.

==== 1. CapRover Setup ====

  * **Installation**: Deploy CapRover on a dedicated OVH Cloud instance.
  * **Dashboard Access**: Access the CapRover dashboard via the web interface.
  * **Initial Configuration**: Configure basic settings such as domain names and SSL certificates.

==== 2. Application Deployment ====

  * **Creating Applications**: Create new applications in CapRover for each service/component.
  * **Deployment Methods**: Deploy applications using Docker images or directly from Git repositories.
  * **Environment Variables**: Configure environment variables for each application as needed.

==== 3. CI/CD Pipeline ====

  * **Git Integration**: Integrate Git repositories with CapRover for automatic deployments.
  * **Build Automation**: Set up automated build processes using CI/CD tools like GitLab CI.
  * **Deployment Automation**: Configure CapRover to automatically deploy new builds to the respective environments.

===== Website and Handbook Deployment =====

Our website and handbook are continuously deployed using CI/CD and hosted on GitLab Pages.

==== 1. Repository Setup ====

  * **GitLab Repository**: Create a GitLab repository for the website and handbook source code.
  * **Branching Strategy**: Implement a branching strategy (e.g., main, develop, feature branches).

==== 2. CI/CD Configuration ====

  * **GitLab CI Configuration**: Define CI/CD pipelines in ''%%.gitlab-ci.yml%%'' file.
  * **Build and Test**: Include stages for building and testing the website/handbook.
  * **Deployment**: Add deployment stages to publish content to GitLab Pages.

==== 3. GitLab Pages ====

  * **Pages Setup**: Configure GitLab Pages to serve the website and handbook.
  * **Custom Domain**: Set up a custom domain for the GitLab Pages site if needed.

===== Best Practices =====

  * **Version Control**: Use Git for version control and maintain a clear commit history.
  * **Code Reviews**: Implement a code review process to ensure quality and consistency.
  * **Security**: Regularly update dependencies and apply security patches.
  * **Backup and Recovery**: Set up regular backups and a recovery plan for critical data.

===== Troubleshooting =====

==== Common Issues ====

  * **Deployment Failures**: Check build logs and CapRover dashboard for error details.
  * **Performance Issues**: Monitor resource usage and optimize application performance.
  * **Network Problems**: Verify network configurations and security group rules.

==== Debugging Tips ====

  * **Logs and Monitoring**: Use logging and monitoring tools to diagnose issues.
  * **Documentation**: Refer to official documentation and community forums for solutions.
