Apache Mesos

By




mesos is private cloud for your data center.

Use available resources in existing cluster.

mesos is less like an cluster management but more like a kernel.



mesos is a distributed system kernel.









so this containers will scale up and down as required.



zookeeper elects new master/scheduler

timeout is also used to kill the master/scheduler.

so if the master/scheduler that failed does not reconnect in the threshold period you will just kill all of the tasks pending there

Terraform

By
Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions. Configuration files describe to Terraform the components needed to run a single application or your entire datacenter. Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure. As the configuration changes, Terraform is able to determine what changed and create incremental execution plans which can be applied. The infrastructure Terraform can manage includes low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc. The key features of Terraform are: Infrastructure as Code : Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and...

Helm: Installation and Configuration

By
PREREQUISITES You must have Kubernetes installed. We recommend version 1.4.1 or later. You should also have a local configured copy of  kubectl . Helm will figure out where to install Tiller by reading your Kubernetes configuration file (usually  $HOME/.kube/config ). This is the same file that  kubectl  uses. To find out which cluster Tiller would install to, you can run  kubectl config current-context or  kubectl cluster-info . $ kubectl config current-context my-cluster INSTALL HELM Download a binary release of the Helm client. You can use tools like  homebrew , or look at  the official releases page . For more details, or for other options, see  the installation guide . INITIALIZE HELM AND INSTALL TILLER Once you have Helm ready, you can initialize the local CLI and also install Tiller into your Kubernetes cluster in one step: $ helm init This will install Tiller into the Kubernetes cluster you saw with  kubectl config current-context . TIP:  Want to install into a different cl...
