I'm using DC/OS 1.8 when i installed Cassandra Service from the DC/OS Universe.
If i stop & start my cluster (master and all nodes) the service doesn't start and i have to uninstall the service, delete all file in the agents node and after install Cassandra service.
P.S. My Cassandra Cluster is installed on Azure with Azure Container Service.
Do you have any idea?
Few questions before we even go further investigation.
1. Have you seen tried to reproduce the issue ? How it is like ?
2. Have you explored DC/OS 1.8 without Azure ? Maybe it is DC/OS issue.
In general, we (Azure Container Service) will have the issue if DC/OS itself is buggy. It is always worth to mine the known issues on DC/OS github first. And yes, we need log

I am fiddling around with Kubernetes on a small managed cluster within AKS.
It looks like I'm ready to go with deploying as my node pools are already provisioned and bootstrapped (or that's what it looks like) upon setup.
Am I missing something here?
Do I really need kubeadm on a managed cloud cluster?
You DO NOT need kubeadm tool when using Azure AKS / AWS EKS / Google GKE managed Kubernetes clusters.
kubeadm is used to create a self-managed Kubernetes cluster.
You can use the kubeadm tool to create and manage Kubernetes clusters. It performs the actions necessary to get a minimum viable, secure cluster up and running in a user friendly way.
I have an existing azure virtual machines that deployed 30 docker containers.
So I have decided to use Kubernetes service/cluster to manage deploy dockers container on that existing azure virtual machines.
I have also deploy azure registry to store docker images.
Is it possible way?
Please help to give me your opinion?
If you are familiar with Ansible then the best way is probably Kubespray. It is capable of creating clusters almost of any complexity and also contains many features that other cluster management tools like kubeadm don't have.
I have a requirement to use Docker containers in PCF deployed in Azure.
And now we want to use kubernetes as container orchestration.
Does kubernetes can be used here ?
Or PCF will take care of the container orchasteration ?
Which one would be the better approach here ?
PKS Is Pivotal's answer to running kubernetes in PCF (regardless of IaaS)
Pivotal Cloud Foundry (PCF) is a sophisticated answer from Microsoft to current cloud expectations. PCF offers the best platform to run Microsoft based technology like .NET, and smoothly supports enterprise Java application. You can run Kubernetes there with fine results, but to achieve comfortable orchestration and management of containers I suggest reading about GKE or setting up your own Kubernetes cluster using kubespray utility.
Cloudera documentation talks about (and, I believe, recommends) use of an edge node (aka gateway node) as a means of controlling external access to the cluster.
I have recently deployed a Cloudera cluster on Azure using the provided ARM template and discovered that no edge node gets provisioned during the deployment. Why is that? If an edge node is recommended should that not be included in such a deployment?
Actually right now every node provisioned using this Cloudera ARM template is an edge node (has the gateway role). This is a simple configuration for smaller clusters. You can customize the template to provision dedicated edge nodes as needed.
I am confused.
Can you install HDInsight Server (multiple nodes) locally, NOT on Azure?
I don't want to install Hortonworks (I know that HDInsight uses their distribution).
Also, I don't want to install any kind of emulator or developer preview with one node.
Again, I would like to install HDInsight on my windows servers on PRODUCTION, how can I do that?
Chicago, I don't think this is possible. HDInsight is a service offered as part of the public Azure offering. If you want to install multiple nodes locally you will need to go with Hortonworks or the Apache Hadoop distribution.
