007- Installing OpenShift

Install OpenShift packages:

[root@master ~]# yum install atomic-openshift-docker-excluder atomic-openshift-excluder atomic-openshift-utils bridge-utils bind-utils git iptables-services net-tools wget

[root@node1 ~]# yum install atomic-openshift-docker-excluder atomic-openshift-excluder atomic-openshift-utils bridge-utils bind-utils git iptables-services net-tools wget

"atomic-openshift-docker-excluder" RPM will be used to avoid changing docker-related packages versions upgrade unless we want that:

[root@master ~]# grep exclude /etc/yum.conf 
exclude= docker*1.20*  docker*1.19*  docker*1.18*  docker*1.17*  docker*1.16*  docker*1.15*  docker*1.14*  docker*1.13*  tuned-profiles-atomic-openshift-node  atomic-openshift-tests  atomic-openshift-sdn-ovs  atomic-openshift-recycle  atomic-openshift-pod  atomic-openshift-node  atomic-openshift-master  atomic-openshift-dockerregistry  atomic-openshift-clients-redistributable  atomic-openshift-clients  atomic-openshift

Remove all openshift-related packages from "/etc/yum.conf" exclude list on the two nodes:

[root@master ~]# atomic-openshift-excluder --help
[...]
unexclude | enable
  removes atomic-openshift atomic-openshift-clients atomic-openshift-clients-redistributable atomic-openshift-dockerregistry atomic-openshift-master atomic-openshift-node atomic-openshift-pod atomic-openshift-recycle atomic-openshift-sdn-ovs atomic-openshift-tests tuned-profiles-atomic-openshift-node from the exclude= line in /etc/yum.conf
  This re-enables updates for packages
[...]
status
  returns status either 'exclude' or 'unexclude' and 0 or 1 respectively


[root@master ~]# atomic-openshift-excluder unexclude
