Konveyor Operator

The Konveyor Operator fully manages the deployment and life cycle of Konveyor on Kubernetes and OpenShift.

Prerequisites

Please ensure the following requirements are met prior installation.

• k8s v1.22+ or OpenShift 4.9+
• Persistent Storage
• Operator Lifecycle Manager (OLM) support
• Ingress support
• Network policy support

Installing OLM support

We strongly suggest OLM support for Tackle deployments, in some production kubernetes clusters OLM might already be present, if not, see the following examples in how to add OLM support to minikube or standard kubernetes clusters below:

Minikube:

$ minikube addons enable olm

$ minikube addons enable ingress

Kubernetes:

$ kubectl apply -f https://raw.githubusercontent.com/operator-framework/operator-lifecycle-manager/master/deploy/upstream/quickstart/crds.yaml

$ kubectl apply -f https://raw.githubusercontent.com/operator-framework/operator-lifecycle-manager/master/deploy/upstream/quickstart/olm.yaml

For details and official instructions in how to add OLM support to kubernetes and customize your installation see here

Note: Please wait a few minutes for OLM support to become available if this is a new deployment.

Kubernetes Network Policies

Tackle can provide namespace network isolation if a supported CNI, such as Calico, is installed.

$ minikube start --network-plugin=cni --cni=calico

Konveyor Operator Installation on k8s

Installing released versions

Released (or public betas) of Konveyor are installable on Kubernetes via OperatorHub.

Installing latest

Deploy Konveyor using manifest:

$ kubectl apply -f https://raw.githubusercontent.com/konveyor/tackle2-operator/main/tackle-k8s.yaml

This step will create the konveyor-tackle namespace, catalogsource and other OLM related objects.

Installing beta (or special branches)

If you need to deploy a beta release (or special branch) please replace the main branch in URL with the desired beta branch (i.e v2.0.0-beta.0):

$ kubectl apply -f https://raw.githubusercontent.com/konveyor/tackle2-operator/v2.0.0-beta.0/tackle-k8s.yaml

Note: Upgrades between beta releases are not guaranteed , once installed, we strongly suggest to edit your subscription and switch to Manual upgrade mode for beta releases: $ kubectl edit subscription -> installPlanApproval: Manual

Creating a Tackle CR

Note: Tackle requires a storage class that supports RWX volumes, please review storage requirements prior creating the Tackle CR in case you need to adjust settings.

$ cat << EOF | kubectl apply -f -
kind: Tackle
apiVersion: tackle.konveyor.io/v1alpha1
metadata:
  name: tackle
  namespace: <your-tackle-namespace>
spec:
EOF

Once the CR is created, the operator will deploy the hub, UI and configure the rest of required components.

Verify Tackle Deployment

Depending on your hardware it should take around 1-3 minutes to deploy Tackle, below is a sample output of a successful deployment

$ kubectl get pods

If you are looking to install Konveyor operator in MacOS, follow along this guide.

Konveyor Operator Installation on OKD/OpenShift

Installing released versions

Released (or public betas) of Konveyor are installable on OpenShift via community operators which appear in OCP and OKD.

1. Visit the OpenShift Web Console.
2. Navigate to Operators => OperatorHub.
3. Search for Konveyor.
4. Install the desired Konveyor version.

Installing latest

Installing latest is almost an identical procedure to released versions but requires creating a new catalog source.

1. oc apply -f https://raw.githubusercontent.com/konveyor/tackle2-operator/main/konveyor-operator-catalog.yaml
2. Visit the OpenShift Web Console.
3. Navigate to Operators => OperatorHub.
4. Search for Konveyor.
5. There should be two Konveyor available for installation now.
6. Select the Konveyor without the community tag.
7. Proceed to install latest using the development channel in the subscription step.

Tackle CR Creation

1. Visit OpenShift Web Console, navigate to Operators => Installed Operators.
2. Select Konveyor.
3. Locate Konveyor on the top menu and click on it.
4. Adjust settings if desired and click Create instance.

Tackle CR Settings

If operator defaults need to be altered, the Tackle CR spec can be customized to meet desired needs, see the table below for some of the most significant settings:

Name	Default	Description
feature_auth_required	true	Enable keycloak auth or false (single user/noauth)
feature_isolate_namespace	true	Enable namespace isolation via network policies
rwx_supported:	true	Whether or not RWX volumes are supported in the cluster
hub_database_volume_size	5Gi	Size requested for Hub database volume
hub_bucket_volume_size	100gi	Size requested for Hub bucket volume
keycloak_database_data_volume_size	1Gi	Size requested for Keycloak DB volume

cache_data_volume_size	100Gi	Size requested for Tackle Cache volume
cache_storage_class	N/A	Storage class requested for Tackle Cache volume
hub_bucket_storage_class	N/A	Storage class requested for Tackle Hub Bucket volume

Tackle CR Customize Settings

Custom settings can be applied by editing the Tackle CR.

oc edit tackle -n <your-tackle-namespace>

Konveyor Storage Requirements
