Fine-Tuning Control Plane Access with Cluster API

Scott Lowe

When Cluster API creates a workload cluster, it also creates a load balancing solution to handle traffic to the workload cluster’s control plane. For flexibility, Cluster API provides a limited ability to customize this control plane load balancer. If you specify “internal” as the scheme, then the load balancer won’t get a public IP address and won’t be reachable via the Internet.

How to set up DHCP failover on Windows Server

Kubernetes Port Names and Terminating HTTPS Traffic on AWS

Scott Lowe

I recently came across something that wasn’t immediately intuitive with regard to terminating HTTPS traffic on an AWS Elastic Load Balancer (ELB) when using Kubernetes on AWS. aws-load-balancer-backend-protocol : http. aws-load-balancer-ssl-cert : arn:aws:acm:{region}:{user id}:certificate/{id}. aws-load-balancer-ssl-ports : "https" spec : selector : app : echo-pod. aws-load-balancer-backend-protocol : http.

Converting Kubernetes to an HA Control Plane

Scott Lowe

With those assumptions and that caveat in mind, the high-level overview of the process looks like this: Create a load balancer for the control plane. Create a Load Balancer for the Control Plane. The first step is to create a load balancer for the control plane (a load balancer is required when using multiple control plane nodes). As I mentioned earlier, the use of a DNS CNAME for the control plane load balancer is recommended.).

Looking back at 10 years of compartmentalization at AWS

All Things Distributed

By using zones, and failover mechanisms such as Elastic IP addresses and Elastic Load Balancing, you can provision your infrastructure with redundancy in mind. The calls used to launch and manage EC2 instances, fail over an RDS instance, or handle the health of instances behind a load balancer, all work within one zone. At AWS, we don't mark many anniversaries.

Consuming Pre-Existing AWS Infrastructure with Cluster API

Scott Lowe

In the case of AWS, this includes VPCs, subnets, route tables, Internet gateways, NAT gateways, Elastic IPs, security groups, load balancers, and (of course) EC2 instances. Cluster API will take care of security groups, load balancers, and EC2 instances; these do not need to be created in advance. All the posts I’ve published so far about Kubernetes Cluster API (CAPI) assume that the underlying infrastructure needs to be created.

Creating an AWS ELB using Pulumi and Go

Scott Lowe

You can probably infer from the code above that this example creates an ELB that listens on TCP port 6443 and forwards to instances on TCP 6443 (and is therefore most likely a load balancer for the control plane of a Kubernetes cluster). In case you hadn’t noticed, I’ve been on a bit of a kick with Pulumi and Go recently. There are two reasons for this.

Using the AWS CLI to Tag Groups of AWS Resources

Scott Lowe

Without the necessary tags, the AWS cloud provider—which is responsible for the integration that creates Elastic Load Balancers (ELBs) in response to the creation of a Service of type LoadBalancer , for example— won’t work properly. To conduct some testing, I recently needed to spin up a group of Kubernetes clusters on AWS. Generally speaking, my “weapon of choice” for something like this is Cluster API (CAPI) with the AWS provider.

Kubernetes on OpenStack: The Technical Details

Scott Lowe

For inbound connectivity, this is where Kubernetes Services come into play; you could have a Service of type NodePort (unique port forwarded by kube-proxy on every node in the Kubernetes cluster) or a Service of type LoadBalancer (which uses a cloud load balancer with nodes & NodePorts as registered backends). Load balancing is the next connection point that Lees reviews.
