Detailed explanation of relevant knowledge points of golang packaging and deployment

As an open source high-performance programming language, golang is favored by more and more developers. After the development of Golang is completed, we need to carry out packaging and deployment. This article will introduce you to the relevant knowledge points of golang packaging and deployment.

1. Golang project packaging

In the golang project, we can use the go build command to package the project, which can compile the source code into an executable program. When executing the go build command, an executable file will be generated, which can be run on any operating system that supports golang.

We can open the terminal or command line, enter the project directory, and execute the go build command to generate an executable file.

go build

After executing this command, if there is no error message, you can see the generated executable file in the project directory and execute the file in the terminal or command line.

2. Golang project deployment

When deploying the golang project, we can use the following methods:

1. Copy the binary file directly

Just copy the packaged binary file directly to the server. For simple projects, this is the simplest deployment method.

2. Deploy using Docker

Docker is an open source containerization platform that can package applications and their dependencies into a container, which can then be deployed in any Docker-enabled operation Running in the system ensures the cross-platform and portability of the application. Using Docker can simplify the deployment process and greatly reduce the difficulty of system management.

We can write a Dockerfile in the project to describe how to build the image. In the Dockerfile, you can specify the base image, install dependency packages, copy files and other operations, and then use the docker build command to build the image:

docker build -t my_project .

After executing this command, the image will be built and Marked as my_project, . indicates the directory where the Dockerfile is located.

Then, we can use the docker run command to create and start the container, as shown below:

docker run -p 8080:80 my_project

This command means to map port 80 in the container to 8080 of the host port, and use the my_project image to create a container and start it.

3. Deployment using Kubernetes

Kubernetes is an open source container orchestration platform that can automatically deploy, scale and manage containerized applications. Use Kubernetes to quickly build highly available and highly scalable applications.

We can write a Kubernetes deployment description file in the project to describe how to deploy the application. The Kubernetes description file can describe the number of copies of the application, container images, container ports, resource limits and other information.

Then, use the kubectl command to deploy the description file to the Kubernetes cluster:

kubectl apply -f my_project.yaml

This command means that the my_project.yaml file The described application is deployed into a Kubernetes cluster.

3. Summary

Golang is packaged and deployed. You can use the go build command to generate binary files for deployment, or you can use Docker and Kubernetes for containerized deployment. Among them, Docker can ensure the cross-platform and portability of applications, while Kubernetes can quickly build highly available and highly scalable applications. Developers can choose the appropriate deployment method according to the actual situation.
