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

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

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum repolist
repo id repo name
docker-ce-stable/x86_64 Docker CE Stable - x86_64

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:

   Copy Copied!

   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:

   Copy Copied!

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