Devops Pipeline Setup For Cicd

Sure, let's set up a basic CI/CD pipeline using Git, Jenkins, and Ansible. We'll assume that you already have a web-based project management tool hosted on a Git repository. For simplicity, I'll provide a basic example, and you may need to customize it based on your project's specific requirements. ### Stage 1: Unit Testing 1. Create a `Jenkinsfile` in the root of your project repository. ```groovy pipeline { agent any stages { stage('Unit Test') { steps { script { // Assuming your unit tests are executed using a specific command, e.g., npm test, pytest, etc. sh 'your_unit_test_command' } } } } post { success { echo 'Unit tests passed. Proceeding to the next stage.' } failure { error 'Unit tests failed. Aborting pipeline.' } } } ``` **Continue** ### Stage 2: Integration Testing 2. Update the `Jenkinsfile` to include the integration testing stage. ```groovy pipeline { // ... (previous stages) stages { // ... (previous stages) stage('Integration Test') { steps { script { // Assuming your integration tests are executed using a specific command. sh 'your_integration_test_command' } } } } post { // ... (previous post section) success { echo 'Integration tests passed. Proceeding to the next stage.' } failure { error 'Integration tests failed. Aborting pipeline.' } } } ``` **Continue** ### Stage 3: Compile Source Code 3. Add the compilation stage to the `Jenkinsfile`. ```groovy pipeline { // ... (previous stages) stages { // ... (previous stages) stage('Compile') { steps { script { // Assuming your source code is compiled using a specific command. sh 'your_compile_command' } } } } post { // ... (previous post section) success { echo 'Source code compiled successfully. Proceeding to the next stage.' } failure { error 'Compilation failed. Aborting pipeline.' } } } ``` **Continue** ### Stage 4: Deploy to Staging Environment 4. Add the deployment stage using Ansible. Create an Ansible playbook, e.g., `deploy.yml`, and an inventory file, e.g., `inventory/staging`. ```yaml # deploy.yml --- - hosts: staging tasks: - name: Copy files to staging server copy: src: /path/to/compiled/files dest: /path/on/staging/server ``` 5. Update the `Jenkinsfile` to include the deployment stage. ```groovy pipeline { // ... (previous stages) stages { // ... (previous stages) stage('Deploy to Staging') { steps { script { // Assuming Ansible is installed on the Jenkins server sh 'ansible-playbook -i inventory/staging deploy.yml' } } } } post { // ... (previous post section) success { echo 'Deployment to staging environment completed. Pipeline finished successfully.' } failure { error 'Deployment to staging environment failed. Aborting pipeline.' } } } ``` This basic pipeline covers unit testing, integration testing, compilation, and deployment to a staging environment. Depending on your project, you might need additional steps such as security scanning, code analysis, and more. Customize the pipeline according to your specific needs.
