Creator: https://github.com/trungvo11 Crossplane is an open-source project in the Cloud Native Computing Foundation (CNCF) that transforms your Kubernetes cluster into a universal control plane. It enables platform teams to assemble infrastructure from multiple vendors and expose higher-level self-service APIs for application teams to consume, without writing any code. Crossplane extends your Kubernetes cluster to support…
Mình đang câng viết 1 tool golang và sẽ access vào EKS để call tiếp các API của K8S Chúng ta đi sơ qua 1 chút về Đây là kubeconfig mà bạn hay sử dụng để access vào eks cluster. Bạn có thể thấy khi access vào eks cluster thì kubeclt sẽ cần gõ một…
To authenticate with AWS using the AWS Command Line Interface (CLI), you have several methods available, depending on your needs and configuration. Below are the primary methods for authentication: 1. Using IAM User Credentials This is a common method for individuals or applications that need direct access to AWS services. Steps: 2. Using IAM Identity…
refer to install:https://github.com/awslabs/mountpoint-s3/blob/main/doc/CONFIGURATION.md Mountpoint for Amazon S3 is optimized for applications that need high read throughput to large objects, potentially from many clients at once, and to write new objects sequentially from a single client at a time.==> S3 Mountpoint này sẽ hỗ trợ cho việc ghi file mới và đọc file từ nhiều client…

NodeLocal DNSCache NodeLocal DNSCache enhances Kubernetes cluster DNS performance by deploying a DNS caching agent on each node as a DaemonSet. This setup allows Pods to query a local DNS cache on the same node, reducing latency and avoiding potential bottlenecks associated with centralized DNS services. PILLAR__DNS__DOMAIN is “cluster.local” by default.PILLAR__LOCAL__DNS is the local listen IP…

Bài toán ở đây là client sẽ đưa ra cho chúng ta 1 list subnet. Mục đích của chúng ta là chỉ lựa ra mỗi Zone chúng ta sẽ lấy ra 1 subnet để sử dụng để cài đặt hệ thông: The Solution: Step-by-Step Example 2. Fetch Subnet Information: You want to check the availability…
1) Understand FSx Lustre to support EKS. Amazon FSx for Lustre is designed for high performance and its throughput and IOPS scale with the storage capacity you provision. This means there aren’t fixed maximums like with EFS. Instead, you get more throughput and IOPS as you increase your storage cũng như EFS, FSx Lustre cũng…

Monitoring capabilities AWS provides: You are responsible for: Instance level monitoring Instance monitoring BufferCacheHitRatio: The percentage of requests that are served by the buffer cache. – When data is requested, AWS DocumentDB first checks if it is available in the buffer cache (in-memory). – If the data is available in the cache, the request is…
refer to: https://ramimac.me/aws-iam-tools-2024?ref=dailydev Identity and Access Management (IAM) is a cornerstone of security. However, AWS IAM is not only crucially important, but also immensely complex. This complexity and the resultant challenges it can pose for security have not gone unnoticed. In addition to efforts at education, AWS has developed Zelkova, an automated reasoning tool for AWS…
