Getting Started Install kops Before we can bring up the cluster we need to install the CLI tool kops. Install kubectl In order to control Kubernetes clusters we need to install the CLI tool kubectl. Other Platforms Kubernetes Latest Release Installation Guide Setup your environment AWS In order to correctly prepare your AWS account for kops, we require you to install the AWS CLI tools, and have AP
The kOps tool itself takes the (minimal) spec of a cluster that the user specifies, and computes a complete configuration, setting defaults where values are not specified, and deriving appropriate dependencies. The "complete" specification includes the set of all flags that will be passed to all components. All decisions about how to install the cluster are made at this stage, and thus every decis
Route53 Mapping Service This addon is deprecated. Please use external-dns instead. This is a Kubernetes controller that polls services (in all namespaces) that are configured with the label dns=route53 and adds the appropriate alias to the domain specified by the annotation domainName=sub.mydomain.io. Multiple domains and top level domains are also supported: domainName=.mydomain.io,sub1.mydomain.
README.md Kubernetes CoreOS cluster With this tutorial one creates a Kubernetes CoreOS cluster containing of one master and three minions (workers) running on 192.168.10.1-192.168.10.4. For working correctly you need to create the directory addressed as POOL_PATH in util.sh: $ sudo mkdir /var/lib/libvirt/images/kubernetes $ sudo chown -R $USER:$USER /var/lib/libvirt/images/kubernetes/ Then we foll
AWS Compute Blog Manage Kubernetes Clusters on AWS Using CoreOS Tectonic There are multiple ways to run a Kubernetes cluster on Amazon Web Services (AWS). The first post in this series explained how to manage a Kubernetes cluster on AWS using kops. This second post explains how to manage a Kubernetes cluster on AWS using CoreOS Tectonic. Tectonic overview Tectonic delivers the most current upstrea
AWS Compute Blog Manage Kubernetes Clusters on AWS Using Kops Any containerized application typically consists of multiple containers. There are containers for the application itself, a database, possibly a web server, and so on. During development, it’s normal to build and test this multi-container application on a single host. This approach works fine during early dev and test cycles but becomes
We are running Kubernetes on both sandbox and production for some months now. Our production cluster is still small, with few services running on it, but, most of our sandbox environment is running on a Kubernetes cluster on AWS. We created the clusters with Kops (which is great by the way), but we soon realized that the sandbox cluster was too expensive for our needs. In this article I’ll describ
Cluster Version Upgrades and Migrations At some point you will almost definitely want to upgrade the Kubernetes version of your cluster, or even migrate from a cluster managed/provisioned by another tool to one managed by kops. There are a few different ways to accomplish this depending on your existing cluster situation and any requirements for zero-downtime migrations. Upgrade an existing kube-u
