oVirt-Containers - master snapshot

The repository includes image-specifications (for docker currently) and yaml manifests for openshift to run oVirt deployment (oVirt-Engine and oVirt-Node).

Pre-requisites

Must use oc tool version 1.5.0 - https://github.com/openshift/origin/releases

WARNING
origin-clients rpm installation adds to /bin oc binary that might be older - verify that you work with 1.5 by "oc version"

Getting openshift environment

There are two options - running a cluster of openshift locally or using Minishift VM:

Orchestration using Minishift

Minishift is a VM running openshift cluster in it. This mostly being used for testing for easy and quicker deployment without changing local environemnt

  • Install minishift - https://github.com/minishift/minishift

    Nested virtualization support for the minishift VM

    Since we are going to run VMs inside the minishift VM, it will need nested virtualization support. Minishift documentation suggests to install docker-machine-driver-kvm v0.7.0 but this is not enough to get virtualization support and a more recent one is needed; the right instructions (assuming centos7) to get it are:

    curl -L https://github.com/docker/machine/releases/download/v0.11.0/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine &&
  chmod +x /tmp/docker-machine &&
  sudo cp /tmp/docker-machine /usr/local/bin/docker-machine
curl -L https://github.com/dhiltgen/docker-machine-kvm/releases/download/v0.10.0/docker-machine-driver-kvm-centos7 > /usr/local/bin/docker-machine-driver-kvm &&
  chmod +x /usr/local/bin/docker-machine-driver-kvm

    Nested virtualization support is required on your physical system, please check it with:

    cat /sys/module/kvm_intel/parameters/nested
Y

    If nested virtualization is not supported, please check your OS documentation about how to enable it.

  • Run the following

    export OCTAG=v1.5.0
export PROJECT=ovirt
export LATEST_MINISHIFT_CENTOS_ISO_BASE=$(curl -I https://github.com/minishift/minishift-centos-iso/releases/latest | grep "Location" | cut -d: -f2- | tr -d '\r' | xargs)
export MINISHIFT_CENTOS_ISO=${LATEST_MINISHIFT_CENTOS_ISO_BASE/tag/download}/minishift-centos7.iso

minishift start --memory 6144 --cpus 4 --iso-url=$MINISHIFT_CENTOS_ISO --openshift-version=$OCTAG
export PATH=$PATH:~/.minishift/cache/oc/$OCTAG

Orchestration using 'oc cluster up'

Just follow https://github.com/openshift/origin/blob/master/docs/cluster_up_down.md#linux

Load oVirt to openshift instructions

Login to openshift as system admin

oc login -u system:admin

Create oVirt project

export PROJECT=ovirt
oc new-project $PROJECT --description="oVirt" --display-name="oVirt"

Add administrator permissions to 'developer' user account

oc adm policy add-role-to-user admin developer -n $PROJECT

Force a permissive security context constraints

Allows the usage of root account inside engine pod

oc create serviceaccount useroot
oc adm policy add-scc-to-user anyuid -z useroot

Allows host advanced privileges inside the vdsc pod

oc create serviceaccount privilegeduser
oc adm policy add-scc-to-user privileged -z privilegeduser

Create engine and vdsc deployments and add them to the project

Please note that the engine deployment is configured as paused

oc create -f os-manifests -R

To deploy just engine

oc create -f os-manifests/engine -R

To deploy just vdsc

oc create -f os-manifests/vdsc -R

Change the hostname for engine deployment and unpause it

According to the hostname that was assigned to the associated route

oc set env dc/ovirt-engine -c ovirt-engine OVIRT_FQDN=$(oc describe routes ovirt-engine | grep "Requested Host:" | cut -d: -f2 | xargs)
oc set env dc/ovirt-engine -c ovirt-engine SPICE_PROXY=http://$(oc describe routes ovirt-spice-proxy | grep "Requested Host:" | cut -d: -f2 | xargs):3128
oc patch dc/ovirt-engine --patch '{"spec":{"paused": false}}'

Now you should be able to login as developer user (developer:admin) to the $PROJECT project, the server is accessible via web console at $(minishift console --url)" or locally at https://localhost:8443.
