Docker install Errno 256 Errno 14 HTTPS Error 404 - Not Found

General

As I have done in the past, I am trying to install docker-ce on RHEL 7(ppc64le) like this:

  1. sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
  2. yum repolist
    repo id repo name
    docker-ce-stable/x86_64 Docker CE Stable - x86_64
  3. sudo yum install docker-ce

I get the error output below. I have tried all the solutions recommended, but I think the real error is the very last line in the error output which is:

failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.
https://download.docker.com/linux/centos/7/ppc64le/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

Any suggestions on how to resolve this error?

thanks

One of the configured repositories failed (Docker CE Stable - ppc64le),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

 1. Contact the upstream for the repository and get them to fix the problem.

 2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).

 3. Run the command with the repository temporarily disabled
        yum --disablerepo=docker-ce-stable ...

 4. Disable the repository permanently, so yum won't use it by default. Yum
    will then just ignore the repository until you permanently enable it
    again or use --enablerepo for temporary usage:

        yum-config-manager --disable docker-ce-stable
    or
        subscription-manager repos --disable=docker-ce-stable

 5. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice
    compromise:

        yum-config-manager --save --setopt=docker-ce-stable.skip_if_unavailable=true

failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.

It looks like the the docker-ce from docker.com won’t work on RHEL 7 ppc64le
But here is a build that should, it says for rhel8, but I understand it works for 7 also.
