This project is an add-on to RedHat Openshift Container Platform enabling the deployment with Tungsten Fabric (TF) as SDN

The supported Openshift versions are 4.5 and 4.6

The overall Openshift deploy process is the same as described in the official Openshift documentation

Deploy with TF SDN enabled needs just a few additional steps to the main instruction

In general the steps are in depended on where you are going to install Openshift to - AWS, GCP, KVM ,etc. But for now the project is tested on KVM hypervisor according to baremetal installation procedure.

The below there are addition steps based on baremetal installation procedure

1. Set networkType param to TF in install-config.yaml at the step creating the installation configuration file

2. Add TF Openshift manifests right after step of creation Openshift install manifests

   2.1 Generate the Kubernetes manifests for the cluster (step from the main instruction)

   export INSTALL_DIR=<your installation_directory>
   ./openshift-install create manifests --dir=$INSTALL_DIR

   2.2 Download TF Openshift manifests add add them to the installation (additional step)

   git clone https://github.com/tungstenfabric/tf-openshift.git
   ./tf-openshift/scripts/apply_install_manifests.sh $INSTALL_DIR

   Note: To use non-default NTP servers for Chrony, you need to export NTP_SERVERS before this stage. Example:

   export NTP_SERVERS="0.us.pool.ntp.org 1.us.pool.ntp.org 2.us.pool.ntp.org"
   ./tf-openshift/scripts/apply_install_manifests.sh $INSTALL_DIR

   2.3 Download TF Operator manifests add add them to the installation (additional step)

   git clone https://github.com/tungstenfabric/tf-operator.git
   export CONTRAIL_CONTAINER_TAG=<Containers UBI based images tag (tungstenfabric on dockerhub by default)>
   export CONTAINER_REGISTRY=<Containers UBI based images registry (latest by default)>
   export KUBECONFIG=$INSTALL_DIR/auth/kubeconfig
   export DEPLOYER="openshift"
   export KUBERNETES_CLUSTER_NAME="test1"
   export KUBERNETES_CLUSTER_DOMAIN="example.com"
   export CONTRAIL_REPLICAS=3
   # process manifests (put cluster name, domain etc)
   #   install python3 if missed before:
   #     yum install -y python3
   #     python3 -m pip install jinja2
   ./tf-operator/contrib/render_manifests.sh
   # copy TF CRDs resources
   for i in $(ls ./tf-operator/deploy/crds/) ; do
     cp ./tf-operator/deploy/crds/$i $INSTALL_DIR/manifests/01_$i
   done
   # copy TF operator resources
   for i in namespace service-account role cluster-role role-binding cluster-role-binding ; do
     cp ./tf-operator/deploy/kustomize/base/operator/$i.yaml $INSTALL_DIR/manifests/02-tf-operator-$i.yaml
   done
   oc kustomize ./tf-operator/deploy/kustomize/operator/templates/ | sed -n 'H; /---/h; ${g;p;}' > $INSTALL_DIR/manifests/02-tf-operator.yaml
   # copy TF reources
   oc kustomize ./tf-operator/deploy/kustomize/contrail/templates/ > $INSTALL_DIR/manifests/03-tf.yaml

3. Proceed with main intruction from the step

# Create ignition configs
./openshift-install create ignition-configs --dir=<installation_directory>
