#CICD **CI/CD** stands for **Continuous Integration and Continuous Deployment/Delivery**. It is a set of practices and principles in software development and DevOps aimed at automating and streamlining the processes of building, testing, and deploying applications. The goal is to enhance the efficiency, reliability, and speed of the software development lifecycle while integrating security concerns and version control, and ensuring systematic configuration management for deployment.  #### Continuous Integration (CI) **Continuous Integration** focuses on automating the integration of code changes from multiple developers into a shared repository frequently, often several times a day. The steps involved in CI include: 1. **Code Commit**: Developers regularly commit their code changes to the version control system (e.g., Git). 2. **Automated Build**: An automated build process is triggered whenever code changes are committed, creating a new build of the application. 3. **Automated Testing**: After the build, automated tests are executed to ensure that changes do not introduce regressions or bugs. 4. **Early Feedback**: Developers receive immediate feedback if any issues are found during the build or testing process, allowing them to address problems early in the development cycle. **Security Integration in CI**: - **Static Code Analysis**: Integrate security tools to perform static code analysis, detecting vulnerabilities early in the development process. - **Dependency Scanning**: Automated tools can scan for known vulnerabilities in third-party libraries and dependencies. **Configuration Management**: - **Infrastructure as Code (IaC)**: Use IaC tools (e.g., Terraform, Ansible) to manage and version control infrastructure configurations alongside application code. #### Continuous Deployment (CD) / Continuous Delivery (CD) **Continuous Deployment** and **Continuous Delivery** aim to automate the deployment process of applications to various environments, such as staging and production. The distinction lies in the final deployment step: - **Continuous Deployment**: Changes that pass automated testing are automatically deployed to production without human intervention, ensuring rapid release cycles. - **Continuous Delivery**: The automated deployment process is ready to deploy changes to production, but the actual deployment decision is made manually, providing more control over release timing. **Security Integration in CD**: - **Automated Security Testing**: Incorporate security tests (e.g., penetration tests, vulnerability scans) into the deployment pipeline to ensure security compliance before release. - **Environment Isolation**: Use containerization (e.g., Docker) and orchestration tools (e.g., Kubernetes) to isolate environments, reducing the risk of cross-environment contamination. **Version Control and Configuration Management**: - **Versioned Releases**: Track and manage releases using version control systems, ensuring that every deployment is reproducible. - **Configuration Files**: Store and manage configuration files in version control, ensuring consistency across environments. #### Unified Workflow In a unified CI/CD [[workflow]], security, [[version control]], and [[configuration management]] are integrated to create a cohesive and efficient development process. This workflow includes: 1. **Unified Repository**: A single repository for code, configuration, and infrastructure, ensuring that all components are versioned and managed consistently. See [[Unified Configuration Management]]. 2. **Automated Pipelines**: CI/CD pipelines automate the build, test, and deployment processes, incorporating security checks and configuration management. See [[Permanent/PKM/Tools/GitHub Actions]]. 3. **Continuous Monitoring**: Implement continuous monitoring tools to track the performance and security of applications in production, providing ongoing feedback for continuous improvement. See [[Observability]]. By integrating these elements, development teams can accelerate the development cycle, increase software reliability, and respond more efficiently to customer feedback and changing business requirements. CI/CD is essential in modern software development, particularly in agile and DevOps cultures, where continuous improvement and rapid iteration are vital for success. # References ```dataview Table title as Title, authors as Authors where contains(subject, "CICD") ```
