Kubernetes 1.15 saw new performance improvements, a gradual increase in the stability of management and bootstrap components, and heightened use of custom resources.

Running a database on Kubernetes is closer to the full-ops option, but you do get some benefits in terms How to deploy a database on Kubernetes Now, let's dive into more details on how to deploy a database on Persistent data and consistent naming are two of the largest benefits of StatefulSets.

[init] Using Kubernetes version: vX.Y.Z [preflight] Running pre-flight checks. If the token is expired or you lost the record of the kubeadm join command that kubeadm init outputs, you can also use the kubeadm token create --print-join-command to create a new bootstrap token.

Successfully using Kubernetes and containers with mission-critical databases requires the right level of management and monitoring. It is remarkable how quickly Kubernetes has moved through the hype cycle to become an integral part of the discussion around agile enterprise IT environments for its...

In the Kubernetes docs there is a bootstrap token which is used for Nodes TLS bootstrapping. Wherever it is mentioned there is always the It is used when referring to a token without leaking the secret part used for authentication. The second part is the "Token Secret" and should only be shared...

Bootstrapping a Kubernetes cluster performs the following tasks If your environment uses a Microsoft Exchange Server and SPNEGO, and you want to enable the Orient Mail calendar bar and Action Center calendar integration features, then delete the krb5keytab secret that was...

Are you guys trying to deploy databases on Kubernetes already? Which are the common questions you guys have? I wrote the following article and I would like to hear why you would/would not consider migrating your databases to k8s

Bootstrap Tokens are defined with a specific type (bootstrap.kubernetes.io/token) of secrets that lives in the kube-system namespace. These Secrets are then read by the Bootstrap Authenticator in the API Server. Expired tokens are removed with the TokenCleaner controller in the Controller Manager.

Run Your Database Outside Kubernetes. Kubernetes does have two integrated solutions that make it possible to run your database in Kubernetes These disks are located--as you might guess--remotely from any of the machines and are typically large block devices used for persistent storage.

Scheduling a Kubernetes CronJob that makes a backup of the database. In the script, we create a file name based on the current time, move in the directory pg_backup and create the dump from the database, if we get to exit 0 then we exit the script and with that the container successfully, if it would...

Being able to support data-driven applications with Kubernetes enables more organizations to take advantage of containers for modernizing their legacy apps When deploying a Kubernetes application using the regular deployment and a ReplicaSet or a StatefulSet, you define the application as a...

Bootstrap tokens are a simple bearer token that is meant to be used when creating new clusters or joining Currently, Bootstrap Tokens are alpha but there are no large breaking changes expected. All features for Bootstrap Tokens are disabled by default in Kubernetes v1.6. You can enable the...

About DataStax Accelerate: DataStax delivers the world's only active everywhere database for hybrid cloud. DataStax Accelerate is the best opportunity in the world to learn from a community that builds and Using Kubernetes Local Storage for Scale-Out Storage Services - Michelle Au & Ian Chakeres.

Kubernetes Dashboard is the official web-based UI for Kubernetes. In this deep dive into the Kubernetes Dashboard, we will go through the process of installing, accessing and authenticating the Dashboard as well as adding basic resource metrics via Heapster.

Kubernetes orchestrates clusters of virtual machines and schedules containers to run on those virtual machines based on A large open-source community of developers and companies actively builds extensions and plugins that add capabilities Accelerate the feedback loop with constant monitoring.

Kubernetes is the new kid in town for deploying platforms. Using these tools together we can deploy Cloud Foundry's Control Plane (cloud controller, doppler, routers Below, we'll cover all the moving pieces associated with sprinkling a bit of Cloud Foundry over a nice hot fresh batch of Kubernetes.

This tutorial guides you through deploying the Kubernetes Dashboard to your Amazon EKS cluster, complete with CPU and memory metrics. It also helps you to create an Amazon EKS administrator service account that you can use to securely connect to the dashboard to view and control your cluster.

If we use containers and container orchestration, we ideally make use of Infrastructure-as-Code and store all configuration under version control. In order to inject the bootstrap.properties file into our running container we define a deployment volume that is populated from a Kubernetes secret

While our largest-scale workloads manage bare cloud VMs directly, Kubernetes provides a fast iteration cycle, reasonable scalability, and a lack We now operate several Kubernetes clusters (some in the cloud and some on physical hardware), the largest of which we've pushed to over 2,500 nodes.

When using Kubernetes, most of the time you don't care how your pods are scheduled, but sometimes you care that pods are deployed in order, that they have a persistent storage volume, or that they have a unique, stable network identifier across restarts and reschedules. In those cases, StatefulSets can...

Kubernetes provides fault-tolerance within the cluster, Erlang/Elixir provide it within your application. If your database goes offline, because of a bad configuration or a hardware failure, both the Let's use the database as an example once again. When you are deploying a new version of your software...

In Kubernetes, the operator is how the DevOps team packages, manages and deploys an application, giving it the instructions it needs to run correctly. DataStax has created this operator specifically to run Cassandra with a broad set of assumptions.

The application contains and init/bootstrap script which will deploy hadoop using the configuration in these files. A little bit complicated, but sort of neat. Since this is Hadoop, we can very quickly use some Hadoop utilities to check the state of our Hadoop Cluster running on Kubernetes.
