How do I install docker on RHEL 7 offline?

Question

New to docker.

Need to install docker on a RHEL 7 (no gui) system.

Does the RHEL 7 installation come with docker already on it? If not, where do I get it from? (I cannot use the docker software at docker.com, it has to come from RedHat - government rules, not mine)
Once procured, how do I install it on a system that is not connected to the internet.

I hope I've made my request as simple as possible, let the questions begin.

Note also that the use of Docker on an offline system will be very limited. You will need to supply all images prebuilt or host your own registry. — Robert Kratky, Nov 29 '17 at 07:42

Red Hat's build of docker is available in the Red Hat Enterprise Linux 7 Extras channel, but only for the Server variant of the product. You can download individual packages from the Customer Portal after login, but it is going to be a bit cumbersome because the docker package has multiple dependencies.

Alternatively, you can use the reposync tool to mirror the entire Extras channel on a network-connected machine which has a subscription. Or you can use yum in download-only mode and copy over the RPMs stored in the cache directory (but please copy them to a regular directory on the target, and use yum install to install them).

that's sort of what I'm beginning to run into after I tried installing docker.rpm, is the dependency requirements. Is there not a package/zip file or something out there that has all of it in a single location for install? – CrashFive Nov 28 '17 at 20:26

I think I accidentally posted this in the wrong forum, too, by the way. – CrashFive Nov 28 '17 at 20:27
I added a few suggestions. I do not have much experience with disconnected operation. And yes, it is probably not the right forum. – Florian Weimer Nov 28 '17 at 20:29

Fire up a centos system.

$ sudo yumdownloader docker --resolve

Copy the RPMs over to your RH machine and run:

$ sudo rpm -ivh *rpm
$ sudo systemctl start docker

Gen rpm on CentOS 7 with docker:

$ yumdownloader --resolve docker-ce

Then, install on target:

$ rpm -ivh docker-ce-19.03.11-3.el7.x86_64.rpm
