无法在 RHEL 服务器中安装 docker

Question

我在 RHEL-7 中安装

Requires: fuse-overlayfs >= 0.7

时遇到

docker

错误。

sudo yum install docker-ce
Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

 You could try using --skip-broken to work around

我已经尝试过了

sudo rpm -Uvh http://mirror.centos.org/centos/7/extras/x86_64/Packages/fuse-overlayfs-0.7.2-6.el7_8.x86_64.rpm

Answer 1

在@user3495504的答案之上，我们解决问题的方法是在文件顶部添加一个条目

/etc/yum.repos.d/docker-ce.repo

，内容如下：

[centos-extras]
name=Centos extras - $basearch
baseurl=http://mirror.centos.org/centos/7/extras/x86_64
enabled=1
gpgcheck=1
gpgkey=http://centos.org/keys/RPM-GPG-KEY-CentOS-7

然后安装命令：

yum -y install slirp4netns fuse-overlayfs container-selinux

成功了。

• 启用 gpgcheck

Answer 2

尝试安装 Docker 时也遇到了这个问题。 这有助于获得保险丝覆盖fs

sudo yum install fuse3-devel
wget http://mirror.centos.org/centos/7/extras/x86_64/Packages/fuse-overlayfs-0.7.2-6.el7_8.x86_64.rpm
sudo yum localinstall fuse-overlayfs-0.7.2-6.el7_8.x86_64.rpm

我从 http://mirror.centos.org/centos/7/extras/x86_64/Packages/

获取了包 url

我接下来缺少的是

slirp4netns >= 0.4

。 我将尝试同样的技巧。 是的，这确实有效，并且 docker 安装完成了

 sudo yum install docker-ce docker-ce-cli containerd.io

Answer 3

我在 Oracle Linux 7.9 中安装 docker 版本 20 时遇到了这个问题。相反，安装版本 19，依赖关系没有问题，并且不需要从 CentOS Extras 存储库安装软件包。

sudo yum install docker-ce-19.03.9 docker-ce-cli-19.03.9 containerd.io docker-compose-plugin

编辑

显示所有可用版本

yum list docker-ce --showduplicates | sort -r

Answer 4

请注意，我必须将镜像更改为接受答案的baseurl地址中的vault 从 baseurl=http://mirror.centos.org/centos/7/extras/x86_64 到 baseurl=http://vault.centos.org/centos/7/extras/x86_64

Answer 5

安装fuse3 libs包。这将提供缺少的依赖项。然后在继续进行 docker 安装之前尝试使用保险丝覆盖包
