为了在客户的国产化 Linux 发行版上离线安装 skopeo，静态编译并制作 rpm。

静态编译

下载源码，执行 make help 查看可以编译的目标。

# make help
Usage: make <target>

Defaults to building bin/skopeo and docs

 * 'install' - Install binaries and documents to system locations
 * 'binary' - Build skopeo with a container
 * 'bin/skopeo' - Build skopeo locally
 * 'bin/skopeo.OS.ARCH' - Build skopeo for specific OS and ARCH
 * 'test-unit' - Execute unit tests
 * 'test-integration' - Execute integration tests
 * 'validate' - Verify whether there is no conflict and all Go source files have been formatted, linted and vetted
 * 'check' - Including above validate, test-integration and test-unit
 * 'shell' - Run the built image and attach to a shell
 * 'clean' - Clean artifacts

执行 make bin/skopeo.linux.amd64 和 make bin/skopeo.linux.arm64 编译二进制。

编译得到的二进制是静态二进制，不依赖动态连接库。

# file bin/skopeo.*
bin/skopeo.linux.amd64: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=b6207402e43d0977920992290758b0af29675e09, with debug_info, not stripped
bin/skopeo.linux.arm64: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), statically linked, BuildID[sha1]=73a5d845b9eeb4ee21273a33b33a9b3c5a9fabca, with debug_info, not stripped

制作 RPM

由于之后要制作 deb，所以直接使用 docker.io/library/debian:12.11 作为制作 rpm 的环境。

安装制作 rpm 所需的工具：

  • apt
  • make
# skopeo.spec
%ifarch x86_64
%global goarch amd64
%endif
%ifarch aarch64
%global goarch arm64
%endif
