🔧 DevOps Automation with TuskLang & PHP

Introduction

DevOps automation is the key to rapid, reliable software delivery. TuskLang and PHP let you build sophisticated automation pipelines with config-driven CI/CD, infrastructure as code, and monitoring that accelerates development and reduces risk.

Key Features

- CI/CD pipeline automation - Infrastructure as code - Automated testing - Deployment automation - Monitoring automation - Configuration management

Example: DevOps Configuration

[devops]
ci_provider: github_actions
deployment_target: kubernetes
testing: @go("devops.RunTests")
deployment: @go("devops.Deploy")
monitoring: @go("devops.Monitor")
infrastructure: @go("devops.ManageInfrastructure")

Best Practices

- Automate everything possible - Use infrastructure as code - Implement comprehensive testing - Monitor deployments - Use blue-green deployments - Implement rollback strategies

Performance Optimization

- Optimize build times - Use parallel testing - Implement caching strategies - Monitor pipeline performance

Security Considerations

- Scan for vulnerabilities - Use secrets management - Implement access controls - Audit deployments

Troubleshooting

- Monitor pipeline logs - Check test results - Verify infrastructure state - Monitor deployment health

Conclusion

TuskLang + PHP = DevOps automation that accelerates development and reduces risk. Build pipelines that deliver value faster.
