In the first part, we covered the basics of AWS OpenSearch Service in general and the types of instances for Data Nodes – AWS: Getting Started with OpenSearch Service as a Vector Store. In the second part, we covered access, AWS: Creating an OpenSearch Service Cluster and Configuring Authentication and Authorization. Now let’s write Terraform… Read More »
Quite often for a new project that is just building its infrastructure and CI/CD to do so as an MVP/PoC, and at the beginning, no time is spent on tuning AWS IAM Roles and IAM Policies, but simply connecting AdministratorAccess. Actually, this is exactly what happened in my project, but we are growing, and it’s… Read More »
So, we have an AWS Elastic Kubernetes Service cluster with Authentication mode EKS API and ConfigMap, which we enabled during upgrade of the EKS Terraform module from version 19.21 to 20.0. Before switching EKS Authentication mode completely to the API, we need to transfer all users and roles to Access Entries of the EKS cluster… Read More »

The changes relate to authentication and authorization in AWS IAM and AWS EKS, which I analyzed in the post AWS: Kubernetes and Access Management API, the new authentication in… Read More »
Another very interesting new feature from the latest re:Invent is the EKS Pod Identities: a new ability to manage Pod access to AWS resources. The current state: IAM Roles for Service Accounts Before that, we used the IAM Roles for Service Accounts (IRSA) model, where in order to give a Pod access to, for example,… Read More »
We have two new projects in the Elastic Kubernetes Service (см. AWS Elastic Kubernetes Service: a cluster creation automation, part 1 – CloudFormation), each project lives in its own separate Namespace. In addition, there are two users, developers, who need to be given access to these two Namespaces, but only to Pods in them and… Read More »
We continue the topic of deploying an AWS Elastic Kubernetes Service cluster using Terraform. In the first part, we prepared an AWS VPC. In this part, we’ll deploy the EKS cluster itself, and will configure AIM for it, and in the next parts, we’ll install Karpenter and the rest of the controllers. All the parts:… Read More »
In the previous post ArgoCD: an overview, SSL configuration, and an application deploy we did a quick overview on how to work with the ArgoCD in general, and now let’s try to deploy a Helm chart. The most interesting part of this is how to enable the Helm Secrets. Had some pain with this, but… Read More »
We have a Docker image with the eksctl tool included. We also have an ЕС2 with Linux with the eksctl. There is an AWS IAM Instance Profile attached to this EC2 with the AdminAccess policy assigned. On this ЕС2 we have Jenkins running in a Docker container, and it spawns its jobs inside in additional… Read More »
The task is: create automation to roll out an AWS Elastic Kubernetes Service cluster from scratch. Will use: Ansible: to automate CloudFormation stack creation and to execute eksctl with necessary parameters CloudFormation with NestedStacks: to create an infrastructure – VPC, subnets, SecurityGroups, IAM-roles, etc eksctl: to create a cluster itself using resources created by CloudFormation… Read More »
