无法在RHEL服务器中安装docker

Question

在RHEL-7中安装docker时，我得到了Requires: fuse-overlayfs >= 0.7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

我已经试过了

Answer 1

在@user3495504的答案的基础上，我们解决这个问题的方法是在文件/etc/yum.repos.d/docker-ce.repo的顶部添加一个条目，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

是成功的。

在尝试安装Docker时也遇到了这个问题。这样就可以得到fuse-overlayfs

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/拿到了包裹的网址

对我来说，下一件事就是slirp4netns >= 0.4。我要试试同样的把戏。是的，这确实起作用了，docker安装通过了

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

Answer 3

安装fuse3库程序包。这将提供缺失的依赖项。，然后在继续安装docker之前尝试fuse overlay包。
