CD

Definition

CD, or Continuous Delivery, is a software development practice where code changes are automatically built, tested, and prepared for release to production. It ensures that software can be reliably released at any time, with minimal manual intervention. CD aims to make deployments predictable and routine, reducing the risk of errors and enabling faster delivery of features and fixes.

Secure Settings Example

# Example of a secure CD pipeline configuration in a CI/CD tool like Jenkins
pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                script {
                    // Ensure build environment is isolated
                    docker.image('secure-build-env:latest').inside {
                        sh 'make build'
                    }
                }
            }
        }
        stage('Test') {
            steps {
                script {
                    // Run tests in a secure, isolated environment
                    docker.image('secure-test-env:latest').inside {
                        sh 'make test'
                    }
                }
            }
        }
        stage('Deploy') {
            steps {
                script {
                    // Deploy using secure credentials management
                    withCredentials([usernamePassword(credentialsId: 'deploy-creds', passwordVariable: 'PASS', usernameVariable: 'USER')]) {
                        sh 'deploy-script.sh'
                    }
                }
            }
        }
    }
    post {
        always {
            // Ensure logs are securely archived
            archiveArtifacts artifacts: '**/logs/*.log', allowEmptyArchive: true
        }
    }
}

Insecure Settings Example

# Example of an insecure CD pipeline configuration
pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                // Using a shared environment without isolation
                sh 'make build'
            }
        }
        stage('Test') {
            steps {
                // Running tests without isolation
                sh 'make test'
            }
        }
        stage('Deploy') {
            steps {
                // Hardcoded credentials in the script
                sh 'deploy-script.sh --user admin --password admin123'
            }
        }
    }
    post {
        always {
            // Logs not securely archived
            archiveArtifacts artifacts: '**/logs/*.log'
        }
    }
