在 Fedora 上构建 Docker RPM

Question

我正在尝试从 src.rpm 为 Fedora 中的 docker 构建 RPM。我从这里得到了 src.rpm 包：http://koji.fedoraproject.org/koji/buildinfo?buildID=610523

我正在关注本指南：http://docs.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch11s03.html

现在，我一运行 rpmbuild，就会收到以下错误：

[peeyush@localhost ~]$ rpmbuild --rebuild docker-io-1.5.0-1.fc21.src.rpm 
Installing docker-io-1.5.0-1.fc21.src.rpm
error: Failed build dependencies:

有趣的是，我已经安装了 golang：

[peeyush@localhost ~]$ rpm -q golang
golang-1.3.3-1.fc21.x86_64

请帮我弄清楚这里的问题是什么？或者您能否告诉我是否有其他方法可以构建 docker RPM。

Answer 1

首先，如果您的目标只是安装更新版本的 Docker 软件包，请考虑：

# yum --enablerepo=updates-testing install docker-io

目前你会得到docker-io.x86_64 0:1.5.0-2.fc21。

您需要先安装所有必需的依赖项，然后才能构建包。您可以使用 rpm -q 手动检查源 RPM：

$ rpm -qp --requires docker-io-1.5.0-1.fc21.src.rpm
btrfs-progs-devel
device-mapper-devel
glibc-static
go-md2man
golang >= 1.2.1-3
golang >= 1.3.3
golang(code.google.com/p/go.net/websocket)
golang(code.google.com/p/gosqlite/sqlite3)
golang(github.com/Sirupsen/logrus) >= 0.6.0
golang(github.com/coreos/go-systemd/activation) >= 2-1
golang(github.com/docker/libtrust) >= 0-0.2
golang(github.com/docker/libtrust/trustgraph) >= 0-0.2
golang(github.com/godbus/dbus)
golang(github.com/gorilla/mux) >= 0-0.13
golang(github.com/kr/pty) >= 0-0.19
golang(github.com/syndtr/gocapability/capability) >= 0-0.7
golang(github.com/tchap/go-patricia/patricia)
pkgconfig(systemd)
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1

您可以手动安装这些要求，确保您满足 版本要求，或者您可以使用 yum-builddep 命令，在yum-utils 包中提供：

$ sudo yum-builddep docker-io-1.5.0-1.fc21.src.rpm 

这可能会告诉你：

[...]
Error: No Package found for golang(github.com/docker/libtrust) >= 0-0.2
Error: No Package found for golang(github.com/docker/libtrust/trustgraph) >= 0-0.2

这是因为您尝试构建的包依赖于包 尚未发布的。他们是在updates-testing 存储库，因此您可以运行：

$ sudo yum-builddep --enablerepo=updates-testing \
  docker-io-1.5.0-1.fc21.src.rpm

这将安装所有要求。
