WIP: This is a work in progress. I intend to start keeping notes of the basic theory, as I experience and learn it, of how to create a good CI/CD for delivering software.
Ensure all code and configuration files are stored in a version control system like Git. This allows tracking changes, collaboration, and easy rollback of changes if needed.
Automate the process of building the software to ensure that the code is always in a deployable state, minimizing integration issues and detecting problems early.
Integrate code changes frequently, at least once a day, to detect issues early and reduce the time it takes to find and fix bugs.
Implement various levels of automated testing (unit, integration, and end-to-end) to ensure that the code is of high quality and meets the requirements.
Automatically deploy every change to a production-like environment after passing all the automated tests, allowing for quicker feedback and faster iterations.
Infrastructure as code:
Manage infrastructure and configurations using code and version control to achieve consistency, repeatability, and scalability.
One Artifact, One Pipeline, One Path to Production:
Monitoring and observability:
Implement comprehensive monitoring and observability tools to track the performance and health of the application and infrastructure, enabling quick identification and resolution of issues.
Establish feedback loops between development, operations, and business teams to ensure continuous improvement and alignment with business goals.
Collaboration and communication:
Promote a culture of collaboration and open communication between development, operations, and other stakeholders to break down silos and increase efficiency.
Automate Security and compliance:
Integrate security and compliance practices into the CI/CD pipeline, including automated security testing and code analysis, to ensure that the application meets regulatory requirements and is secure from potential threats.
Scalability and resilience:
Design the pipeline to support scalability and resilience, enabling the application to handle increased load and recover quickly from failures.
