Is it possible to install DockerCE in the specific version 17.03 on RHEL7 ?
There is information here:
I had the same problem running 7.x and I did the following:
yum install -y yum-utils
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
subscription-manager repos --enable=rhel-7-server-extras-rpms
yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.55-1.el7.noarch.rpm
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl restart docker
With this you'll not fall on the pigz error
Error: Package: docker-ce-18.03.1.ce-1.el7.centos.x86_64 (docker-ce-stable)
Requires: pigz
You could try using --skip-broken to work around the problem
Also you need to keep an eye on the container-selinux since i'm using a direct link to the version 2.55-1
