<h2 id="whatisdockerkubernetes" class="smc-tutorial-h2">What is Docker Kubernetes?</h2>
<p>Docker and Kubernetes both are comprehensive and effective solutions with powerful capabilities that intelligently manage containerized applications. Kubernetes is a system for container orchestration of Docker containers for automating their scaling, management, placement, and routing that has become famous among the developers and IT operations teams in the current years. It is more extensive than the Docker swarm. It is meant to efficiently coordinate clusters of nodes at scale in production. In short, it is a portable, open-source, and extensible platform that manages the containerized services and workloads. Kubernetes was developed by google first and it contributed to open source in 2014 but now it is maintained by the Cloud Native Computing Foundation.</p>
<h2 id="whydockerkubernetes" class="smc-tutorial-h2">Why Docker Kubernetes?</h2>
<p>In a production environment, some containers need to be managed as they ensure that there is no downtime and the applications run smoothly. They are a good way to bundle and run the applications. For instance, if one container goes down then another one needs to start and it will be a lot easier if it was handled by a system. This is where Kubernetes is a lifesaver. It provides the companies with a framework to run the distributed systems flexibly. Kubernetes takes care of failover and scaling for the application, provides patterns for deployment, and much more such as easily managing a canary deployment of a system. This is why it is so popular among companies and organizations and becomes their first choice.</p>
<h2 id="whyusedockerkubernetes" class="smc-tutorial-h2">Why you should use Docker Kubernetes?</h2>
<p>Kubernetes is a highly flexible container tool that consistently delivers even the most complex applications that run on clusters of hundreds of individual servers. One should always go with Kubernetes as it provides:</p>
<ol>
<li><strong>Automated rollouts and rollbacks – </strong>The user can describe the desired state of his/her deployed container. In short, it can efficiently change the actual state with a controlled rate to the user’s desired state.</li>
<li><strong>Service discovery and load balancing – </strong>A container can be exposed by Kubernetes using the domain name system or their IP address. Further, deployment becomes stable as it loads the balance and distributes the network traffic when traffic to a container is high.</li>
<li><strong>Secret and configuration management – </strong>The users can store and manage their sensitive information like SSH keys, passwords, etc. It lets them deploy and update application configuration and secrets without exposing secrets or rebuilding container images.</li>
<li><strong>Automatic pin backing – </strong>It helps companies make the best use of their resources as it runs containerized tasks using the cluster of nodes efficiently. Moreover, the user can tell it how much CPU and memory to use on each container.</li>
<li><strong>Storage orchestration – </strong>Kubernetes allows the users to prepare a storage system of their own choice like a public cloud provider, local storage, etc.</li>
<li><strong>Self-healing – </strong>Kubernetes has a special self-healing process in which it kills the containers that don’t respond, restart the ones that fail, replaces them, and doesn’t publicize them to customers until they are ready to serve.</li>
</ol>

<p class="smc-p"> <a href="" rel="dofollow">Join Docker Kubernetes Training</a></p></div></blockquote>
<h2 id="dockerkubernetesfeatures" class="smc-tutorial-h2">Docker Kubernetes Features</h2>
<p>Kubernetes has already won the container orchestration war proving why it is the best among every other similar system. It has a lot to offer to its customers. Let’s have a look at the number of features that Kubernetes has to offer to them.</p>
<ul>
<li>Portable and 100% open source</li>
<li>High availability</li>
<li>Workload scalability and designed for deployment</li>
<li>You can create predictable infrastructure</li>
<li>Automated Scheduling</li>
<li>Auto-scalable infrastructure</li>
<li>Self-Healing Capabilities</li>
<li>Application-centric management</li>
<li>Automated rollouts &amp; rollback</li>
<li>Offers enterprise-ready features</li>
<li>Horizontal Scaling &amp; Load Balancing</li>
<li>Provides a higher density of resource utilization</li>
<li>Offers environment consistency for development, testing, and production</li>
<li>Infrastructure is loosely coupled to each component can act as a separate unit</li>
</ul>
<h2 id="dockerkubernetesarchitecture" class="smc-tutorial-h2">Docker Kubernetes Architecture</h2>
<p>Kubernetes has a quite complex architecture with several components in it. The components are:</p>
<ul>
<li><strong>Master node – </strong>This is the first and the most important component in the Kubernetes architecture. It is responsible for the management of the Kubernetes cluster. There can be more than one master node to check for fault tolerance and it is the entry point for all the administrative tasks.</li>
<li><strong>Scheduler – </strong>It is the second component that has the responsibility of scheduling the tasks to slave nodes. Further, it distributes the workload and keeps the resource usage information for every worker node.</li>
<li><strong>Etcd – </strong>Etcd stores wright values and configuration details and communicates with the components to receive the commands and work accordingly. Moreover, it manages the port forwarding activity and network rules.</li>
<li><strong>Worker/Slave nodes – </strong>These nodes are the essential components of the Kubernetes architecture that allows you to assign resources to the container. They contain the required services to manage the networking between containers and communicate with the master node.</li>
</ul>
<ol>
<li>Kubelet: Ensures that described containers are up and running and get the configuration of Pod from the API server.</li>
<li>Docker container: Runs on every worker node that runs the configured pods.</li>
<li>Kube-proxy: Acts as a load balancer and network proxy for performing service on a single server node.</li>
<li>Pods: Combination of single or multiple containers logically running together on nodes.</li>
</ol>
<h2 id="dockerkubernetesbenefits" class="smc-tutorial-h2">Docker Kubernetes Benefits</h2>
<p>There are a lot of similar products as Kubernetes in the market for container management, both commercial and open source. However, Kubernetes has surged in popularity and has become the most widely used solutions because of the benefits that it offers:</p>
<ol>
<li><strong>Impressive heritage: </strong>It has a proven and mature underlying architecture and its design has been built with the 10 years of operational experience by Google engineers that make it the largest container platform in the world.</li>
<li><strong>Ongoing development: </strong>It is continuously developing as it releases new features constantly, fosters collaboration, and has a large and active community.</li>
<li><strong>Outstanding community and industry support: </strong>Kubernetes stands out among all the other container orchestration platforms as it has a broad growth, support, adoption, and popularity. Moreover, it has the support of cloud providers, global enterprises, and IT market leaders.</li>
<li><strong>The rich feature set and application support: </strong>As compared to other container management systems, Kubernetes has a rich feature set. It is flexible enough to meet the changing needs of users and supports a wide set of programming languages, frameworks, and workloads thus enabling stateful, stateless, and data-processing workloads.</li>
</ol>
<h2 id="dockerkubernetesofferings" class="smc-tutorial-h2">Docker Kubernetes New Offerings</h2>
<p>Enterprises and organizations are adopting the container technology as well as Kubernetes with breathtaking speed. It is because it strives to become the best version of itself by constantly upgrading and introducing new features and fixes. In its new upgrade, Kubernetes offers:</p>
<ul>
<li>Unified visibility by combining metrics, events, logs, and security for the view of performance, security, and uptime.</li>
<li>CNCF endorsed collection tools such as Prometheus and FluentD</li>
<li>Application-centric visibility</li>
<li>Upgraded live out-of-the-box dashboards showing live state providing new services</li>
<li>Reduction in time to identify and solve issues</li>
</ul>
<h2 id="dockerkubernetesadvdisadv" class="smc-tutorial-h2">Advantages and Disadvantages of Docker Kubernetes</h2>
<p>Kubernetes facilitates declarative configuration and automation; it provides widely available tools, services, and support and has a large, rapidly growing ecosystem that may make you consider using its services. If you are thinking to adopt Kubernetes for your cloud infrastructure then this section will help you evaluate some of its advantages and disadvantages.</p>
<h4>Advantages –</h4>
<ul>
<li>If this application is used properly, it can greatly increase the efficiency of how your organization works. Additionally, it has a huge ecosystem that reduces the general complexity and gets solutions that you can hardly get yourself.</li>
<li>Kubernetes is a modern technology ranking as the 3<sup>rd</sup> most wanted platform. Software engineers nowadays want to work in companies that use such interesting technologies. In other words, it attracts new and experienced talent in the company.</li>

<p>Designing and deploying apps nowadays requires a lot more than just writing codes. Architectures, multiple languages, discontinuous interfaces between tools and frameworks create vast complexities in each lifecycle stage.  People want software that helps them create containerized apps easily and efficiently and no software can be better than Docker. By the end of this article, you will have a clear understanding of what is Docker, what are its features, benefits, and much more.</p>
<h2 id="whatisdocker" class="smc-tutorial-h2">What is Docker?</h2>
<p>Docker is a tool that is designed to easily create, deploy, and run the applications with the help of containers. It simplifies and accelerates the workflow as well as gives the developers their freedom to innovate with the tools, deployment environment, and application stacks of their choice for every project. But the questions arise that what do containers do? The answer is simple. Containers allow the developers to package up a single application with all the parts that it needs, whether it be libraries or other dependencies. In short, containers combine and deploy the application as one package. Docker is responsible for a significant performance boost and it further reduces the size of the application.</p>
<h2 id="whydocker" class="smc-tutorial-h2">Why Docker?</h2>
<p>Docker is the most popular tool among the organizations and other similar products because it makes it possible to run far more apps on the same old server and making it easy to package and ship programs. But why companies embrace it so much? It’s because Docker keeps it simple. Firstly, it has a friendly, CLI based workflow that makes running, building, and sharing containerized application accessible to the developers having all kinds of skill levels. Secondly, it moves fast, allowing the users to install a single package and run the application in minutes. They can code and test locally along with continuous consistency between development and production. Thirdly and most importantly, it pushes to a cloud-based application registry and collaborates efficiently with the team members.</p>
<h2 id="whyusedocker" class="smc-tutorial-h2">Why you should use Docker?</h2>
<p>There are many similar products in the market similar to Docker such as Apache Mesos, Rancher, etc. then why should one go with Docker? Let us understand this with an example. Suppose a user is working on an analysis in R programming. The user after finishing sends the code to his friend. When the friend runs the same code with the same data sets, it gives a bit different results. This can be because of a different version of R, a different operating system, or any other thing. These things don’t happen with Docker as it solves such problems easily. It acts as a computer inside a computer. The upside to using Docker is when your friend uses the code that you gave; it will give the same results as you did.</p>
<p>In short, one should use Docker because:</p>
<ul>
<li>It ensures that your analysis is reproducible.</li>
<li>It has a great shareability which means you can send Docker containers to anyone who knows how to work with them.</li>
<li>You can wrangle dependencies easily that start from the operating system up to details like Latex package version and R.</li>
<li>It is portable and it sends Docker containers to another machine very easily because of which the users can set up everything on their computer and run analyses.</li>
</ul>
<h2 id="dockerfeatures" class="smc-tutorial-h2">Docker Features</h2>
<p>Docker is now considered one of the fastest-growing technology in web development and DevOps. It provides the following major features to its customers:</p>
<ul>
<li><strong>Security Management: </strong>Allows saving secrets and choosing to provide service access to particular secrets. Also, it includes commands like inspect, creates, etc.</li>
<li><strong>Easy and Faster Configuration: </strong>The users can deploy the code in less time and effort that helps them to configure the system faster and easier.</li>
<li><strong>Services: </strong>It is a list of tasks that specifies the state of a container. Every task represents the instance of a container that needs to be run.</li>
<li><strong>Increase productivity: </strong>It has always helped to execute applications as well as reduced resources easing the technical configuration and increasing productivity.</li>
<li><strong>Routing Mesh: </strong>Routing mesh is responsible for routing incoming requests for ports on available nodes to an active container. It enables connection even if no task is running.</li>
<li><strong>Application Isolation: </strong>This provides containers that are needed to run applications in an isolated environment.</li>
<li><strong>Swarm: </strong>This is a special scheduling and clustering tool for Docker containers.</li>
</ul>
<h2 id="dockerarchitecture" class="smc-tutorial-h2">Docker Architecture</h2>
<p>Client-server architecture is used by Docker. The Docker client talks with the Docker daemon and it is responsible for distributing, building, and running the Docker containers. Both of them are capable of running on the same system. They communicate with the help of REST API over a network interface. Let’s have a look at its components.</p>
<ol>
<li><strong>Docker Daemon: </strong>It listens for the Docker API requests and manages objects like volumes, containers, images, etc. Also, it communicates with other daemons for managing Docker services.</li>
<li><strong>Docker Client: </strong>Docker client is the main way for Docker users to interact with Docker. It allows the Docker client to communicate with multiple daemons.</li>
<li><strong>Docker Registries: </strong>A Docker registry is responsible for storing Docker images. Docker Hub can be used by anyone as it is a public registry. In this, users can even run their private registry.</li>
<li><strong>Docker Objects: </strong>Users create and use images, networks, plugins, volumes, and other objects while using Docker. This section briefs about those objects:</li>
</ol>
<ul>
<li>Images – It is a read-only template that creates a Docker container and comes with instructions. You can create your image or can use created by others.</li>
<li>Containers – It is a runnable instance of the image. With the help of Docker API or CLI, users can delete, stop, start, move, or create containers.</li>
<li>Services – Services are the objects that allow the users to scale containers across several Docker daemons that work together with multiple managers and workers.</li>
</ul>
<h2 id="dockerbenefits" class="smc-tutorial-h2">Docker Benefits</h2>
<p>Both the developers and system administrators benefit vastly from Docker. Developers can focus on writing the code without worrying about the system and the operational staff gets the flexibility and reduces the number of systems that are needed because of lower overhead and small footprints. Besides that, it provides many more benefits to them such as:</p>
<ol>
<li><strong>Security: </strong>There are many components in a large application that are separated into different containers. It has its security benefits such as if one container is compromised, others won’t be affected by it.</li>
<li><strong>Reproducibility: </strong>Docker containers are identically the same on any other system that has Docker as the same container specifications are stored in a Dockerfile. Moreover, it gives a well-documented and constant environment making it easier to keep track and identify issues.</li>
<li><strong>Environment Management: </strong>It helps maintain a different version of everything. It provides separate containers for development, production, and testing and can be easily deployed anytime.</li>
<li><strong>Isolation: </strong>The applications are divided into containers due to which conflicting dependencies can be avoided. Users can even have multiple projects on a single server without creating conflicts on their system.</li>
<li><strong>Docker Hub: </strong>The Docker Hub has many well-maintained images available. So, it can quickly pull a premade image making the process simple and fast.</li>
<li><strong>Continuous Integration: </strong>Docker works well with tools like Jenkins, Travis, etc. So, whenever the source code is updated, the tools save the latest version as a Docker image, tags it with a number, pushes to the Docker Hub, and then deploys it to production.</li>
</ol>
<h2 id="dockerofferings" class="smc-tutorial-h2">Docker New Offerings</h2>
<p>Docker is the most popular and user-friendly solution to share, configure, and save server environments using containers. Due to this, installing an application has become as simple as running Docker run or pull. In its latest update, Docker has included some new offerings that developers couldn’t resist the temptation of. This time, the Docker team focused on developer experience. It included the following things:</p>
<ul>
<li>Improved collaboration and control</li>
<li>New vulnerability scanning and support enhance Docker Pro</li>
<li>Docker dashboard now welcomes local images and hub</li>
<li>Docker open sources compose for Microsoft ACI and Amazon ECS</li>
<li>Released Github Action V2</li>
<li>More secure than ever and it ensures best practices</li>
</ul>
<h2 id="dockeradvdisadv" class="smc-tutorial-h2">Advantages and Disadvantages of Docker</h2>
<p>Docker is a new and emerging technology. However, like any other tool, it is still under development. It has some limitations proving that it is not right for every project. In this section, we will learn about Docker’s pros and cons so that you can decide whether it is a good addition to your company or not.</p>
<h4>Advantages –</h4>
<ul>
<li>For container management, Docker produces an API in an image format and a chance to use remote registries for container sharing.</li>
<li>It decreases the application size and enables them to deploy fast as it has the containers that carry minimal runtime requirements for it.</li>
<li>Users can share their containers with others easily.</li>
<li>The Docker images are small that results in rapid delivery and reduction in time to deploy a new application.</li>
<li>Users can pursue a container’s succeeding versions, can inspect irregularities, and can go back to previous versions too.</li>
<li>All the dependencies of an application can be grouped in separate containers. These containers can be allotted to other machines that have Docker and can be easily performed without any adaptability issue.</li>
</ul>
<h4>Disadvantages –</h4>
<ul>
<li>In Docker, graphical applications do not work well.</li>
<li>Data storage is intricate as all the data inside a container vanishes if it closes down unless you’ve saved it somewhere else.</li>
<li>Some applications do not benefit from Docker at all.</li>
<li>Although Docker is an open-source platform still some container products don’t work with other products at all.</li>
<li>Lastly, containers in Docker don’t work at bare metal rates because of interfacing, host system, overlay networking, etc.</li>
</ul>

<h2 id="openshiftarchitecture" class="smc-tutorial-h2">OpenShift Architecture</h2>
<p>OpenShift has a layered architecture in which each layer is tightly bound with the others using Docker and Kubernetes cluster. It is designed in such a way that Docker containers are easily supported and managed that is hosted on the top layers. additionally, the new OpenShift V3 supports containerized infrastructure. Here, Docker helps in the creation of lightweight containers whereas Kubernetes manages the containers and supports the task of orchestrating.</p>
<p>The two components of OpenShift are Kubernetes master and Kubernetes nodes.</p>
<h4>Kubernetes Master Machine Components</h4>
<ul>
<li>Etcd – It is responsible for storing configuration information that can be used by every node in the cluster.</li>
<li>API Server – Kubernetes is an API server that provides all the operations on the cluster with the help of API.</li>
<li>Controller Manager – The controller Manager is held accountable for the collectors that regulate the state of a particular cluster and perform tasks.</li>
<li>Scheduler – It is the main component that is responsible for distributing the workload, tracking the utilization of working load on cluster nodes, and analyzing which resources are available.</li>
</ul>
<h4>Kubernetes Nodes Components</h4>
<ul>
<li>Docker – It helps in running the application containers in an isolated but lightweight operating environment.</li>
<li>Kubelet Service – This service is a small service present in each node responsible for transferring information to and from control plane service.</li>
<li>Kubernetes Proxy Service – This runs on every node and makes sure that the services are available to the external host.</li>
</ul>
