Start using this Workflow
Continuous Integration/Continuous Deployment (CI/CD) Checklist
Version Control
Ensure all application code is stored in a version control system (e.g., Git).
Adopt a branching strategy (e.g., Gitflow or feature branching) appropriate for the project workflow.
Enforce code reviews and pull requests before merging changes into the main branch.
Automated Testing
Implement unit tests to cover critical functions of the codebase.
Set up integration tests to verify that different parts of the application work together correctly.
Create end-to-end tests to simulate user scenarios and validate the overall behavior of the application.
Build Automation
Configure a build system (e.g., Jenkins, Travis CI, CircleCI) to automatically compile and build the application.
Ensure the build process includes code quality checks, such as linting and static analysis.
Package the application and its dependencies into a deployable artifact, such as a Docker container or a binary.
Deployment Automation
Develop scripts or use deployment tools (e.g., Ansible, Terraform, Kubernetes) to automate the provisioning of infrastructure.
Automate the deployment process to enable consistent and repeatable deployments to different environments (e.g., staging, production).
Implement rollbacks or blue-green/canary deployment strategies to minimize downtime and risk during deployment.
Monitoring and Feedback
Set up monitoring tools (e.g., Prometheus, Datadog, New Relic) to track application performance and availability.
Collect and analyze logs to identify issues and understand user behavior using tools like ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk.
Establish feedback loops with alerts and notifications to quickly respond to system failures or performance degradation.
Security and Compliance
Integrate security scanning tools (e.g., SonarQube, OWASP ZAP) into the CI pipeline to identify vulnerabilities early.
Ensure that all sensitive data is encrypted in transit and at rest, and manage secrets securely using tools like HashiCorp Vault or AWS Secrets Manager.
Regularly update dependencies to patched versions and perform periodic security audits to maintain compliance with security standards.
Documentation and Knowledge Sharing
Maintain up-to-date documentation for the CI/CD process, including build, deployment, and rollback procedures.
Document the architecture and dependencies of the application to facilitate understanding and maintenance.
Encourage knowledge sharing through code comments, internal wikis, and regular team discussions or retrospectives.
