This detailed tutorial answers the question of how to leverage Amazon's AWS Fargate container technology for GitLab Runners.

To meet user demand, dynamic HTTP-based applications require constant scaling of Kubernetes pods. For applications exposed through Kubernetes ingress objects, the AWS Application Load Balancer (ALB) distributes incoming traffic automatically across the newly scaled replicas. When Kubernetes applications scale down due to a decline in demand, certain situations will result in brief interruptions for end […]

Kubernetes is a scalable container orchestrator that helps you build fault-tolerant, cloud native applications. It can handle automatic container placement, scale up and down, and provision resources for your containers to run. While Kubernetes can take care of many things, it can’t solve problems it doesn’t know about. Usually these are called unknown unknowns and […]

This is official Amazon Web Services (AWS) documentation for Amazon Elastic Kubernetes Service (Amazon EKS). Amazon EKS is a managed service that makes it easy for you to run Kubernetes on AWS without needing to install and operate your own Kubernetes clusters. Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications.

For every deploy, scale down event, or pod termination, users of GitLab's Pages service were experiencing 502 errors. This explains how we found the root cause and rolled out a fix for it.

Amazon Elastic Kubernetes Service (Amazon EKS) managed service makes it easy to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control plane. When Amazon EKS was made generally available in 2018, it supported self-managed node groups. With self-managed node groups, customers are responsible for configuring the Amazon Elastic Compute […]

Me writing YAMLModern infrastructure work is, by many measures, better than it has ever been. We live in a time when a lot of the routine daily problems have been automated away by cloud providers, tooling or just improved workflows. However in the place of watching OS upgrades has come

Overview Karpenter is a high-performance Kubernetes cluster autoscaler that can help you autoscale your groupless nodes by letting you schedule layered constraints using the Provisioner API. Karpenter also makes node upgrades easy through the node expiry TTL value ttlSecondsUntilExpired. This blog post will walk you through all of the steps to make this possible, and […]

FEATURE STATE: Kubernetes v1.21 [deprecated] Note: This feature, specifically the alpha topologyKeys API, is deprecated since Kubernetes v1.21. Topology Aware Hints, introduced in Kubernetes v1.21, provide similar functionality. Service Topology enables a service to route traffic based upon the Node topology of the cluster. For example, a service can specify that traffic be preferentially routed to endpoints that are on the same Node as the client, or in the same availability zone.

FEATURE STATE: Kubernetes v1.23 [beta] Topology Aware Hints enable topology aware routing by including suggestions for how clients should consume endpoints. This approach adds metadata to enable consumers of EndpointSlice and / or Endpoints objects, so that traffic to those network endpoints can be routed closer to where it originated. For example, you can route traffic within a locality to reduce costs, or to improve network performance. Motivation Kubernetes clusters are increasingly deployed in multi-zone environments.

Kubernetes creates DNS records for services and pods. You can contact services with consistent DNS names instead of IP addresses. Introduction Kubernetes DNS schedules a DNS Pod and Service on the cluster, and configures the kubelets to tell individual containers to use the DNS Service's IP to resolve DNS names. Every Service defined in the cluster (including the DNS server itself) is assigned a DNS name. By default, a client Pod's DNS search list includes the Pod's own namespace and the cluster's default domain.
