Let's talk about the concept and usage of golang deployment files

In the field of software development, deployment is the last step in the development process and a key step in bringing the application online. In recent years, golang has become the primary development language for more and more companies. Therefore, it becomes very important to understand the concept and usage of golang deployment files when deploying golang applications.

1. The concept of golang deployment files

Golang deployment files refer to files used to package and deploy golang applications. Golang deployment files usually include the following main parts:

1. Executable file: This is a binary file that can run the compiled golang application on the target machine.

2. Configuration file: This file is used to store the configuration information of the golang application, such as database connection information, log level, port number, etc.

3. Static files: These files can be css, js, html, etc., used for static resource files after starting the golang application.

4. Log files: These files are used to store log information of golang applications, such as error information, debugging information, etc.

5. Database files: These files include database scripts and data files, used for persistent storage of golang applications.

2. Use golang deployment files to deploy applications

1. Write a golang application: First, we need to write a golang application and generate an executable file.

2. Prepare the configuration file: Next, we need to prepare a configuration file and save the application-related configuration information in this file.

For example, we can define database connection information, listening port number, etc. in the configuration file.

3. Packing files: After determining which files we need to pack, we can start packaging the files. We can use some open source tools such as Golang build tools, make pack, etc., and enter packaging instructions on the command line.

For example, you can use the following command to compile and package the executable file, configuration file and static file into an executable file:

go build -o myapp main.go
tar czvf myapp .tar.gz myapp conf static

4. Upload files: Next, we can upload the packaged files to the target machine. File transfer tools such as FTP and SCP can be used to complete the upload. After the upload is complete, we need to decompress the file on the target machine.

For example:

tar xzvf myapp.tar.gz

5. Start the application: Finally, we need to start the application on the target machine. You can use the following command to start:

./myapp

So far, we have completed the use of golang deployment files. Using this method to deploy golang applications can help developers proceed faster Application is online.
