Kube OBLV Stack

Overview

The Kube OBLV Stack is a software stack that is specifically designed to be deployed on Kubernetes environments. It uses multiple components and configurations to make managing cloud-native applications easier and more scalable.

The Kube OBLV Stack simplifies the deployment, management, and scaling of applications on Kubernetes clusters. It accomplishes this through a variety of operational tasks such as continuous integration and deployment (CI/CD), networking, load balancing, and DNS management.

Configuration

The configuration of the Kube OBLV Stack is managed via Helm, a package manager for Kubernetes used to simplify the deployment and management of applications. Below is a description of the configuration command:

helm upgrade -i oblv-deploy-stack oci://<OBLV-AWS-ACCOUNT-ID>.dkr.ecr.eu-west-1.amazonaws.com/kube-oblv-stack \
    --version 1.2.1-alpha \
    -n kube-system \
    --set oblv-deploy-chart.enabled=true \
    --set aws-load-balancer-controller.enabled=true \
    --set aws-load-balancer-controller.clusterName=<EKS-CLUSTER-NAME> \
    --set aws-load-balancer-controller.serviceAccount.create=false \
    --set aws-load-balancer-controller.serviceAccount.name=aws-load-balancer-controller \
    --set external-dns.enabled=true \
    --set external-dns.provider=aws \
    --set external-dns.txtOwnerId=<EKS-CLUSTER-NAME>-external-dns \
    --set external-dns.domainFilters="{oblv.com}" \
    --set external-dns.serviceAccount.name=external-dns \
    --set external-dns.serviceAccount.create=false \
    --set external-dns.policy=sync

The command line above is described in the table below:

Parameter	Description
helm install oblv-deploy-stack	Initiates the installation of the Kube OBLV Stack.
oci://.../kube-oblv-stack	Specifies the OCI image repository hosted on AWS ECR in the eu-west-1 region.
--version 1.2.1-alpha	Sets the version of the stack to 1.2.1-alpha.
-n kube-system	Deploys the stack within the 'kube-system' namespace.
--set oblv-deploy-chart.enabled=true	Enables the OBLV Deploy chart.
--set aws-load-balancer-controller.enabled=true	Enables the AWS Load Balancer Controller for managing load balancing.
--set aws-load-balancer-controller.clusterName=<EKS-CLUSTER-NAME>	Associates the controller with the specified Kubernetes cluster.
--set aws-load-balancer-controller.serviceAccount.name=aws-load-balancer-controller	Specifies the service account for the AWS Load Balancer Controller.
--set aws-load-balancer-controller.serviceAccount.create=false	Disables creation of a new service account for the AWS Load Balancer Controller.
--set external-dns.enabled=true	Enables External DNS to manage DNS records dynamically.
--set external-dns.provider=aws	Sets AWS as the DNS provider for handling DNS management.
--set external-dns.txtOwnerId=<EKS-CLUSTER-NAME> -external-dns	Assigns ownership of DNS records to a specific cluster entity.
--set external-dns.domainFilters[0]="oblv-test.com"	Restricts DNS management to the domain 'oblv-test.com'.
--set external-dns.serviceAccount.name=external-dns	Designates the service account for managing DNS records.
--set external-dns.serviceAccount.create=false	Indicates that a new service account should not be created for External DNS.
--set external-dns.policy=sync	Sets the policy for DNS record synchronisation to 'sync', meaning it will update as changes occur.

Upgrading

The command above can be used to upgrade as well as to perform a fresh install.
