Installation

• 1: Preparing to install
• 2: Installing on OpenShift
• 3: Uninstalling on OpenShift

1 - Preparing to install

Pre-requirements

Get familiarized with the architecture reading this section.

A valid Resiliency Operator license key and registry access key should already be assigned.

Supported platforms

Astronetes Resiliency Operator is vendor agnostic meaning that any Kubernetes distribution such as Google Kubernetes Engine, Azure Kubernetes Service, OpenShift or self-managed bare metal installations can run it.

This is the certified compatibility matrix:

Kuberentes requirements

Software

Official kubernetes.io client CLI kubectl.

Networking

• Allow traffic to the Image Registry quay.io/astrokube using the mechanism provided by the chosen distribution.
• In a 3-clusters architecture, the management cluster needs to have communication with both the destination and source cluster. Note that it is not necessary to also allow connections between the target clusters. Due to the lack of a centralised management cluster, in a 2-clusters architecture communication between destination and source should be enabled.

OpenShift requirements

Software

OpenShift client CLI.

Networking

• Add quay.io/astrokube to the allowed registries in the Image configuration.
• In a 3-clusters architecture, the management cluster needs to have communication with both the destination and source cluster. Note that it is not necessary to also allow connections between the target clusters. Due to the lack of a centralised management cluster, in a 2-clusters architecture communication between destination and source should be enabled.

apiVersion: config.openshift.io/v1
kind: Image
metadata:
    ...
spec:
  registrySources: 
    allowedRegistries: 
    ...
    - quay.io/astrokube

Cluster configuration

• Cluster admin permission in management, destination and source clusters. In a 2-clusters architecture it is only required to have admin permissions in the destination and source clusters as the operator activities will be delegated to the former.
• The Secret provided by AstroKube to access the Image Registry.
• The Secret provided by AstroKube with the license key.

2 - Installing on OpenShift

The following operations need to executed in both the management and destination cluster.

Process

1. Create Namespace

Create the Namespace where the operator will be installed:

oc create namespace resiliency-operator

2. Setup registry credentials

Create the Secret that stores the credentials to the AstroKube image registry:

oc -n resiliency-operator create -f pull-secret.yaml

3. Setup license key

Create the Secret that stores the license key:

oc -n resiliency-operator create -f license-key.yaml

4. Install the operator

Install the CRDs:

oc apply -f https://astronetes.io/deploy/resiliency-operator/v1.0.0/crds.yaml

Install the operator:

oc -n resiliency-operator apply -f https://astronetes.io/deploy/resiliency-operator/v1.0.0/operator-openshift.yaml

3 - Uninstalling on OpenShift

Process

1. Delete Operator objects

Delete the synchronizations from the management cluster:

oc delete synchronizationplans.automation.astronetes.io,synchronizations.automation.astronetes.io -A --all

Delete the assets from the management cluster:

oc delete databases.assets.astronetes.io -A --all

2. Remove the operator

Delete the operator:

oc -n resiliency-operator delete -f https://astronetes.io/deploy/resiliency-operator/v1.0.0/operator-openshift.yaml

Delete the CRDs:

oc delete -f https://astronetes.io/deploy/resiliency-operator/v1.0.0/crds.yaml

3. Remove registry credentials

Delete the Secret that stores the credentials to the AstroKube image registry:

oc -n resiliency-operator delete -f pull-secret.yaml

4. Remove license key

Delete the Secret that stores the license key:

oc -n resiliency-operator delete -f license-key.yaml
