AWS - APIGW with IAM Authorizer

-

 

In the previous post, we saw how to create an API GW with Lambda. In this post, we will see how to add an IAM Authorizer to the API GW. 

So, all the calls to API GW must be authenticated and authorized via the IAM user's Access and Secret Keys.



I already have an IAM user called "rsinfominds".

I added APIGW Invoke permission to the user and made a note of the access and secret key.



Now, We have an IAM user. Let's update the existing API GW with the IAM authorizer.


Finally hit deploy to save the changes. Now, It's time to test it via Postman.



It works. We got the reply "Hello from Lambda".

K8s - ETCD

  etcd is a "strongly consistent , distributed key-value store". Why etcd? 1. Consistency : Since the API server is the central coordination point of the entire cluster; strong consistency is essential. It would be a disaster if, say, two nodes tried to attach the same persistent volume over iSCSI because the API server told them both that it was available. 2. Availability: API downtime means that the entire Kubernetes control plane comes to a halt, which is undesirable for production clusters. The  CAP theorem  says that 100% availability is impossible with strong consistency, but minimizing downtime is still a critical goal. 3. Consistent Performance: The API server for a busy Kubernetes cluster receives a fair amount of read and write traffic. The secret behind etcd's balance of strong consistency and high availability is the  Raft algorithm . Raft solves a particular problem: how can multiple independent processes decide on a single value for somethin...

K8s - Deployment and HPA replicas

-
Image
  We all know that replica is a critical part of a K8s deployment. Default replica is 1. Setting replicas as 3 will ensure 3 pods of that deployment is running at any given time.  Replica are internally managed by replica set which is in turn controlled by the K8s  ReplicationController   . When a pod is bad or deleted as part of replicaset, replication controller will ensure a new pod is created. Now, coming to HPA (Horizontal Pod Autoscaler) which is a dynamic scaler which works at the pod level based on the metrics configured.  When we configure we must mention min and max values. They should be greater than 1. Let's image I create a HPA with min as 5 and max as 10 under the condition of CPU utilization more than 50%. Initial deployment is set with the replica as 1. On top the deployment, I am attaching a HPA with the mentioned configuration. Under HPA, we are forcing the min replicas to 5. Hence, it autoscales the pod to 5 even though the CPU utilization is ...
