I was quite surprised when it shot up into the air. When he had it all designed, he told me to stand way back. I had no idea what he was doing at the time, but I was intrigued. I do remember seeing him use a cork, a bunch of cardboard, a bicycle pump, and a two-liter bottle. It all seemed a bit complicated for such a young kid, but he had a mind for stuff like that. We’re happy to help.I remember my brother designing homemade bottle rockets when he was ten.
If you’d like to try WKP on EKS cluster with Bottlerocket please contact our sales team.
#BOTTLE ROCKET UPDATE#
With Bottlerocket, you get a robust OS with atomic and a secure update mechanism for Kubernetes. To check that have everything setup properly by running kubectl get nodes and/or describe nodes. Afterward your Bottlerocket-powered GitOps-managed WKP cluster will be ready.Īnd you’ll have an automatically upgradable WKP cluster. We’ll then see WKP starting up a cluster running on Bottlerocket OS:Īfter that add the YAML files of the Bottlerocket Update controller to the cluster/manifest and then commit and push. With the same node group configuration, we can just copy the nodegroup and put it into the WKP setup/config.yaml. $ eksctl create cluster -f eks-cluster.yaml WKP on Bottlerocket OS Let’s save the above file as eks-cluster.yaml and then type the following command to create an EKS cluster running on Bottlerocket OS: If we enable the update via these labels, the node will be updated via TUF when there’s a new AMI of Bottlerocket available. These labels will be detected by the update operator of Bottlerocket. To achieve that, we have to label each node with bottlerocket.aws/platform-version and bottlerocket.aws/update-interface-version. One of the most important points in this configuration is to ensure that each Kubernetes node can be updated automatically. Set the value for the amiFamily field to Bottlerocket and the ami field to auto-ssm so that EKSctl automatically searches for the correct Bottlerocket AMI for the different regions. This is an example of the cluster configuration file used for preparing an EKS cluster with Bottlerocket OS. We can define a node group and tell the group that we are using the Bottlerocket AMI Family. With EKSctl, Bottlerocket can be defined in a node group.
#BOTTLE ROCKET HOW TO#
Later in this post, we will also show how to apply the same cluster configuration used by EKSctl to create a cluster with WKP also on top of the Bottlerocket OS.
#BOTTLE ROCKET UPGRADE#
This will further simplify the upgrade and maintenance process for platforms built with WKP. In the next release of WKP, we plan to ship a feature that supports out-of-the-box provisioning of EKS clusters with Bottlerocket OS. We are also excited to announce that the Bottlerocket OS is now fully compatible with the WKP (Weave Kubernetes Platform), our production ready platform with GitOps as the underlying architecture and developer experience that simplifies cluster configuration and management across your organization. In this post, we will show how to use our tool, EKSctl - the official CLI for EKS - to spin up an EKS cluster which is powered by Bottlerocket OS.īottlerocket OS and the Weave Kubernetes Platform (WKP) Today, we can use Bottlerocket OS to power our EKS clusters and let its updating mechanism to automatically take care of our Kubernetes versions. This ensures that every update will be both secure and reliable. Everything must be together with a particular kernel version, Kubernetes, and its OS packages. One of its design principles is that it does not allow individual packages to be upgraded. Bottlerocket ships with a specific version of Kubernetes along with a set of operating system packages that have been tested and work well together. It is designed to be updated in an atomic and secure way using The Update Framework (TUF).īottlerocket OS was originally designed to support general containerized workloads and the current version now supports EKS clusters. Bottlerocket is the new operating system from AWS.
