[SOLVED] Cannot install docker in a RHEL server

Issue

I am getting Requires: fuse-overlayfs >= 0.7 error while installing docker in RHEL-7.

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

I already tried

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

Solution

Building on top of @user3495504's answer, what we did to fix the problem was adding an entry on top of the file /etc/yum.repos.d/docker-ce.repo, with this content:

[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

Then the installation command:

yum -y install slirp4netns fuse-overlayfs container-selinux

was successful.

[Edit]

  • enabled gpgcheck
