Procedure

To install Che on OpenShift 3 using the operator:

  1. Log in to OpenShift (copy the login command from the OpenShift console):

    $ oc login https://master.rhpds311.openshift.opentlc.com:443 --token=<token>
    log into openshift

  2. Check if the latest oc binary tool is installed on the system:

    $ oc version
oc v3.11.0+0cbc58b
kubernetes v1.11.0+d4cacc0
features: Basic-Auth

Server https://master.rhpds311.openshift.opentlc.com:443
openshift v3.11.43
kubernetes v1.11.0+d4cacc0

  3. Give a domain to chectl. This is the remote hostname that will be accessible. If it is unknown, obtain it with a new project using the following command:

    $ oc new-project hello-world
$ oc new-app centos/httpd-24-centos7~https://github.com/openshift/httpd-ex
$ oc expose svc/httpd-ex
$ oc get route httpd-ex
NAME     HOST/PORT                                                PATH     SERVICES PORT     TERMINATION WILDCARD
httpd-ex httpd-ex-hello-world.apps.rhpds311.openshift.opentlc.com httpd-ex          8080-tcp             None

  4. Extract the domain from httpd-ex-hello-world.apps.rhpds311.openshift.opentlc.com. It is the part after the first name: apps.rhpds311.openshift.opentlc.com.

  5. Remove the project:

    $ oc delete project hello-world
