Gopack

Gopack is a tool that simplifies the process of building and packaging Go applications. It can be used to create distributable binaries for various platforms, as well as to package those binaries into archives or containers.

Features

• Cross-platform building: Gopack can build binaries for Windows, macOS, Linux, and other operating systems with a single command.
• Embedded version information: Gopack can embed version information, build time, and other metadata directly into the application binary.
• Archive packaging: Gopack can package built binaries into Zip, Tar, Gz, and Bz2 archives for easy distribution.
• Container packaging: Gopack can build Docker containers containing your application and all its dependencies.

Installation

You can install Gopack using Go's built-in package manager:

go get -u github.com/lunny/gopack

Usage

To build a binary for your current system, simply run:

gopack build

This will compile your application and create an executable file in the current directory.

To build a binary for a different operating system or architecture, use the target flag:

gopack build --target=linux/amd64

This will build a Linux binary for the x86_64 architecture.

To package your built binary into an archive, use the pack command:

gopack pack --input=myapp --output=myapp.tar.gz

This will create a myapp.tar.gz archive containing the myapp executable.

To build a Docker container containing your application, use the docker command:

gopack docker --input=myapp --tag=myusername/myapp:latest

This will build a Docker image with the myusername/myapp:latest tag, containing the myapp executable and all its dependencies.

Conclusion

Gopack is a powerful tool for simplifying the process of building and packaging Go applications. Its cross-platform building and packaging features make it easy to distribute your application to users running different operating systems, while its Docker integration allows for easy container-based deployment.
