What are the best practices for deployment and operation in the Golang framework?

Best practices for deploying and operating Go applications include: Tracking code changes using a version control system. Create Docker images for consistent operation. Use deployment tools like Kubernetes for automation and management. Gradually release new versions through grayscale release to reduce risks. Monitor application metrics using Prometheus and Grafana. Set alarms to notify operations personnel in a timely manner. Enable logging and centralize storage for easy troubleshooting. Regularly update applications and underlying systems.

Go framework application deployment and operation and maintenance best practices

In the deployment and operation and maintenance process of Go applications, follow Best practices are critical to ensure the continued stable operation of your application. The following are some recommended practices:

Deployment phase

• Use a version control system:By using a version control system such as Git, you can Track code changes and manage different versions.
• Create a Docker image: Packaging the application into a Docker image can ensure that the application runs consistently in different environments.
• Use deployment tools: Use deployment tools such as Kubernetes and Helm to automate the deployment process and manage the expansion and contraction of the application.
• Conduct grayscale release: Gradually release new versions to different groups of users to monitor performance and reduce risks.

Operation and maintenance phase

• Monitoring applications: Use tools such as Prometheus and Grafana to monitor application indicators, such as CPU usage, memory usage, and request times.
• Set up alerts: Configure alerts to notify operations personnel when specific metrics reach thresholds.
• Using logging: Enable logging and store it in a centralized location for easy troubleshooting and debugging.
• Perform regular maintenance: Regularly update applications, underlying systems, and middleware as needed.

Practical Case

Let’s consider a web application written in Go and deployed on Kubernetes.

• Deployment: Deploy the application using Helm, which will create Kubernetes resources to manage the deployment.
• Operation and maintenance: Use Prometheus to monitor application metrics and use Grafana to create dashboards for visualization. Alerts are configured to notify operations staff when CPU usage reaches 80%. Log records are written to Elasticsearch using Fluentd for centralized search and analysis. Regular maintenance includes updating application versions and upgrading Kubernetes clusters.

By following these best practices, the deployment and operation process of Go applications can be significantly improved, and the stability, reliability, and scalability of the application can be improved.
