无法在 RHEL 服务器中安装 docker

Question

在 RHEL-7 中安装 docker 时出现 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

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

基于@user3495504 的回答，我们解决问题的方法是在文件/etc/yum.repos.d/docker-ce.repo 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

然后是安装命令：

yum -y install slirp4netns fuse-overlayfs container-selinux

成功了。

• 启用 gpgcheck

Answer 2

在尝试安装 Docker 时也遇到了这个问题。这有助于获得 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/获得了包裹网址

我接下来缺少的是slirp4netns >= 0.4。我要尝试同样的伎俩。是的，这确实有效，并且 docker install 完成了

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

Answer 3

安装 fuse3 库包。这将提供缺少的依赖项。然后在进行 docker install 之前尝试 fuse overlay 包
