Re: Docker related issues when installing openshift origin 1.5 on Redhat 7.2



Thanks for the information.

I missed this section when I read the documentation.

For RHEL this section of the documentation should cover all of the registration and repo requirements
https://docs.openshift.com/container-platform/3.5/install_config/install/host_preparation.html#host-registration

For Centos I think this will work, but the repo should be enabled by default already.
yum-config-manager --enable extras

Hi Scott,

Yes, repo used for installing docker is from yum.dockerproject.com.

Another basic question is how could I enable RHEL docker repo to install docker.

I'm not familiar with redhat.

You have docker from the upstream repos installed and unfortunately we're not compatible with their packaging. Please use docker from rhel/centos/fedora repos. You may have to enable the extras repo if it's not currently enabled and remove all docker packages before retrying.

Hello :)
Can you share with us your inventory file?
Openshift provides several additional variables realted to your issue, see below:

# Specify exact version of Docker to configure or upgrade to.
# Downgrades are not supported and will error out. Be careful when upgrading docker from < 1.10 to > 1.10.
# docker_version="1.12.1"

# Skip upgrading Docker during an OpenShift upgrade, leaves the current Docker version alone.
# docker_upgrade=False

Best regards

Hi guys,

I tried to install openshift origin 1.5 on Redhat with docker 1.12.6 installed on each host.

However, it seeded that ansible tried to install docker 1.9 instead of using 1.12.6.

Is this expected behavior? If not, how could I fix such problem?

The detailed error is as below,


TASK [docker : Error out if attempting to upgrade Docker across the 1.10 boundary] ************************************************************
