To create a container cluster on google cloud For overlay network, Kubernetes has several options, but using flannel is the easier solution.įlannel also uses etcd to configure the settings and store the status. Kubernetes uses an overlay network to manage multiple containers’ communication. However, Kubernetes usually works as a cluster and ambassador pattern or overlay network could help to connect every node. If the container’s network communication is only within the single host, you can use the Docker link to generate the environment variable to discover the peer. Because when you start to run the Docker, an IP address will be assigned dynamically the container application needs to know the peer’s IP address and port number. Overlay network Network communication between containers is the most difficult part. Kubernetes uses etcd as the main datastore. It can be accessed via the RESTful API to perform the CRUD operation over the network. There are two more components to complement the Kubernetes nodes’ functionalities, the datastore etcd, and the overlay network flannel.Įtcd The etcd ( ) is the distributed key-value datastore. For example, kubectl get cs returns the status of each component.

Attempts to change the current status to the desired statusĬommand Line Interface (kubectl) After you install Kubernetes master, you can use the Kubernetes Command Line Interface kubectl to control the Kubernetes cluster.

Creates and updates the Kubernetes internal information.

It is a simple algorithm that defines the priority to dispatch and bind containers to nodes, for example:Ĭontroller manager (Kube-controller-manager) Controller manager performs cluster operations. Scheduler (Kube-scheduler) Scheduler helps to choose which container runs by which nodes. Hypercube wrapper launched all of them.ĪPI server (Kube-apiserver) The API server provides an HTTP- or HTTPS-based RESTful API, which is the hub between Kubernetes components, such as kubectl, scheduler, replication controller, etcd datastore, and kubelet and Kube-proxy, which runs on Kubernetes nodes and so on. There are several daemon processes that make the Kubernetes master’s functionality, such as Kube-apiserver, Kube-scheduler, and Kube-controller-manager.

Container deployment scheduler to the Kubernetes nodes.

It serves several functionalities, such as the following items: Kubernetes master Kubernetes master is the main component of Kubernetes cluster.

Kubernetes nodes use an overlay network (for example, flannel) to make a connection of their container applications.

Kubernetes nodes connect to the Kubernetes master via HTTP or HTTPS to get a command and report the status.

It also connects flannel to access the container application.

Kubernetes master connects to etcd via HTTP or HTTPS to store the data.

Transbase-® offers maximum speed for database queries, especially with the complex search queries that are typical in many database applications.These components are connected via a network, as shown in the following screenshot: The preceding image can be summarized as follows: It is these database structures in combination with security and back-up concepts that guarantee continuously reliable operation without the need for reorganization.

Transbase-® is specifically designed for large, incremental databases. They are used for clustered primary indexes as well as for secondary indexing. Technology: Highly developed prefix B+ trees form the underlying data structure of Transbase-®. Properties:The outstanding features of Transbase-® are its great flexibility and performance, its powerful SQL-92 extensions, its heterogeneous client-server architecture, its strict transaction processing and its compatibility with CD/DVD ROM in connection with Internet updating. Available add-ons for Transbase-® are the powerful modules Transbase-® Fulltext, Transbase-® CD, Transbase-® Hypercube and Transbase-® D. Transbase-® is Transaction Software's main product. Transbase-® is a distributed, relational SQL database system.
