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.
