Containerization is the most prominent trend in software and application development currently. It is generally assumed as a supporting element or alternative for virtualization. Containerization involves the packaging of software code and all related dependencies for running uniformly without any issues on any infrastructure. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Containerization technology is gradually gaining maturity, thereby providing tangible benefits for developers and operations teams. Also, containerization presents credible benefits for the complete software infrastructure. With the help of containers, developers could easily create and deploy applications with better security and speed. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Traditional methods involved code development in a particular computing environment, and transfer of code development to a new environment resulted in errors and bugs. Containerization deals with this problem through bundling of the application code with configuration files, dependencies, and libraries for running it. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">The bundle of software or \u2018container\u2019 abstracts away from the host operating system, thereby implying its portability. Containers are very high in demand, currently with almost 61% of enterprise employees trying out their hands at containerization technology. The prominent highlight in the world of container tools is the dominance of Kubernetes and Docker. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Kubernetes is very popular among large businesses, while Docker is the crowd favorite and is popular among organizations of different sizes. But where is OpenShift in this equation? Interestingly, OpenShift is also making huge strides by gaining popularity as a container application platform powered by Kubernetes. If you&#8217;re aspiring to learn OpenShift, you can start with a quick <a href=\"https:\/\/www.whizlabs.com\/blog\/red-hat-openshift\/\" target=\"_blank\" rel=\"noopener\">OpenShift tutorial<\/a> and get ahead.<\/span><\/p>\n<p><a href=\"https:\/\/www.whizlabs.com\/learn-kubernetes-with-aws-and-docker\/\" target=\"_blank\" rel=\"noopener noreferrer\"><img decoding=\"async\" class=\"aligncenter wp-image-71809 size-full td-animation-stack-type0-2\" src=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2019\/04\/Kubernetes_with_AWS_and_Docker.gif\" alt=\"Kubernetes with AWS and Docker\" width=\"728\" height=\"90\" \/><\/a><\/p>\n<h3 class=\"p1\" style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Comparing_Docker_and_Kubernetes\"><\/span><span class=\"s1\">Comparing Docker and Kubernetes<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">After the overview of the present status of the world of container tools, let us start reflecting on the individual comparisons. The first point of comparison would be between docker and Kubernetes. First of all, definitions of Kubernetes and then the definition of docker can support this discussion on OpenShift vs Kubernetes vs docker. <\/span><\/p>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Definitions<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Kubernetes is a production-grade container orchestration system. It provides an opensource toolkit for the creation of a fault-tolerant scalable platform meant for automation and central management of containers. The features on Kubernetes can make it classified as a container platform, a microservices platform, or a portable cloud platform. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">On the other hand, Docker is a containerization technology that has recently become popular in the world of application packaging and the cloud. Docker is an open-source framework that helps in the automation of application deployment through simple, portable, and lightweight containers. Various Linux kernel features, including cgroups and namespaces, as well as configurable virtual environments.<\/span><\/p>\n<blockquote><p><strong>Also Check:<\/strong>\u00a0<a href=\"https:\/\/www.whizlabs.com\/blog\/docker-tips-and-tricks\/\" target=\"_blank\" rel=\"noopener noreferrer\">Top 12 Docker Tips and Tricks<\/a><\/p><\/blockquote>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Reasons for Popularity<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">A closer look at the features which make Kubernetes and Docker popular can be prominent comparison points in Kubernetes vs docker evaluations. So now, we should focus on observing the reasons for which Docker and Kubernetes are popular to support our discussion on OpenShift vs Kubernetes vs docker. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\"> Kubernetes addresses the majority of operational concerns for application containers. Also, it is the largest open-source project in the world presently with prolific levels of community support. The other features include sturdy container deployment, effective persistence in storage, and multi-cloud support. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">You can also find Kubernetes as a promising instrument for monitoring container health and management of computing resources. The support of auto-scaling features and real-world use cases can simplify the applications of Kubernetes, thereby raising its popularity. Furthermore, the assurance of high availability in Kubernetes leads to its popularity. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">The prominent factors supporting the popularity of Docker include speed, ease of use, and free pricing. The container-based approach takes away the need for separate operating systems and multiple hardware resources. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Docker provides core features that enterprises need in a container platform, along with best practices for ensuring success. Also, containers comply with legacy applications as well as new developments easily. Most important of all, Docker allows the containerization of mission-critical applications. As a result, you can achieve prolific savings in infrastructure, along with reduced labor and improved security. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">An observation of the popularity points for Kubernetes as well as docker mentioned above shows their effectiveness in application deployment. However, the differences form crucial aspects of Kubernetes vs docker. Let us take a look at the various points of differences between these two.<\/span><\/p>\n<blockquote><p>Kubernetes certifications are among the top 5 DevOps certifications. Read our previous blog to know about <a href=\"https:\/\/www.whizlabs.com\/blog\/best-devops-certifications\/\" target=\"_blank\" rel=\"noopener noreferrer follow\" data-wpel-link=\"internal\">Top DevOps Certifications<\/a>.<\/p><\/blockquote>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Setup and Installation<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">In terms of setup and installation, Kubernetes needs a series of manual steps for setting up Kubernetes master and worker nodes. On the other hand, Docker installation requires only a one-liner command on the Linux platform like Ubuntu. Kubernetes could run on different platforms, and the single-node Kubernetes cluster setup requires a Minikube. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">On the other hand, the installation of a single-node Docker Swarm or Kubernetes cluster is possible through the deployment of Docker. Kubernetes Client and Server packages need manual upgrades on all systems. The ease of upgrading the Docker Engine makes it easily done in one-click.<\/span><\/p>\n<blockquote><p>Enroll Now:\u00a0<a href=\"https:\/\/www.whizlabs.com\/docker-swarm-basics\/\" target=\"_blank\" rel=\"noopener follow noreferrer\" data-wpel-link=\"internal\">Docker Swarm Basics Online Course<\/a><\/p><\/blockquote>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Usage<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Another point of comparison between docker and Kubernetes in our discussion on OpenShift vs Kubernetes vs Docker refers to usage. Kubernetes is ideal for operations at the application level rather than the hardware level and can support diverse workloads. You can run Kubernetes on top of Docker with knowledge about command-line interface specifications. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">The working of the Docker platform is visible in two different editions. The Docker community edition involves community-based support forums, and Docker Enterprise edition provides enterprise-class support. The Docker enterprise edition provides private support channels and assurance of defined SLAs.<\/span><\/p>\n<table class=\"t1\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td class=\"td1\" valign=\"top\">\n<p class=\"p1\"><span class=\"s2\"><b>Criteria<\/b><\/span><\/p>\n<\/td>\n<td class=\"td1\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\"><b>Kubernetes<\/b><\/span><\/p>\n<\/td>\n<td class=\"td1\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\"><b>Docker<\/b><\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td2\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\"><b>Definition<\/b><\/span><\/p>\n<\/td>\n<td class=\"td2\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\">Container orchestration system<\/span><\/p>\n<\/td>\n<td class=\"td2\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\">Containerization technology<\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td3\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\"><b>Features<\/b><\/span><\/p>\n<\/td>\n<td class=\"td3\" valign=\"top\">\n<ul class=\"ul1\">\n<li class=\"li2\"><span class=\"s2\">Multi-cloud support<\/span><\/li>\n<li class=\"li2\"><span class=\"s2\">Robust container deployment<\/span><\/li>\n<li class=\"li2\"><span class=\"s2\">Effective persistent storage<\/span><\/li>\n<li class=\"li2\"><span class=\"s2\">High availability<\/span><\/li>\n<\/ul>\n<\/td>\n<td class=\"td3\" valign=\"top\">\n<ul class=\"ul1\">\n<li class=\"li2\"><span class=\"s2\">Speed <\/span><\/li>\n<li class=\"li2\"><span class=\"s2\">Ease of use<\/span><\/li>\n<li class=\"li2\"><span class=\"s2\">Free pricing<\/span><\/li>\n<li class=\"li2\"><span class=\"s2\">Core enterprise features<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td4\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\"><b>Setup and installation<\/b><\/span><\/p>\n<\/td>\n<td class=\"td4\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\">Series of manual steps<\/span><\/p>\n<\/td>\n<td class=\"td4\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\">One-line command on Linux system<\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td5\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\"><b>Usage<\/b><\/span><\/p>\n<\/td>\n<td class=\"td5\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\">Suitable for application-level operations<\/span><\/p>\n<\/td>\n<td class=\"td5\" valign=\"top\">\n<p class=\"p2\"><span class=\"s2\">Available in two different editions with Docker Enterprise edition offering enterprise-class support.\u00a0<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<blockquote><p>Red Hat OpenShift 4 is the next generation of trusted enterprise Kubernetes platform.

Since we have already found the definition of Kubernetes and the main reasons for its popularity, let us find about OpenShift. OpenShift is also a container platform like Docker with the credibility of Red Hat as its developer. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">The primary product of OpenShift is the OpenShift container platform that has Kubernetes in underlying architecture for container management. OpenShift involves a lot of cloud solutions, and it can be accounted for as a family of solutions. For example, OpenShift Origin is the opensource cloud-based platform of Red Hat used for building, testing, and deploying applications to the cloud. <\/span><\/p>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Popular Features<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Some of the notable features which make OpenShift a popular go-to alternative for containerization can help this discussion. First of all, the in-built security checks in the container stack across the application lifecycle provide constant security. The next important feature refers to in-built monitoring through a database and application monitoring software, Prometheus.<\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Therefore, OpenShift moves a step ahead in the battle of OpenShift vs Kubernetes with the feature to visualize applications in real-time. OpenShift also provides centralized policy management with a single console across various clusters to implement policies. The compatibility aspect of OpenShift with Kubernetes is also a prominent factor in Kubernetes and OpenShift.<\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">OpenShift is a component of the <a href=\"https:\/\/www.whizlabs.com\/blog\/certified-kubernetes-administrator-exam-preparation\/\" target=\"_blank\" rel=\"noopener\">Certified Kubernetes Administrator<\/a> program and shows compatibility with Kubernetes container workloads. <\/span><span class=\"s1\">So, what are the differences between these two? Let\u2019s find out! The foremost aspect of the comparison battle of OpenShift vs Kubernetes is the base. The base is Linux, albeit with each product running in a different environment. <\/span><\/p>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Platform for Usage<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Kubernetes needs to run on a Linux distribution OS while OpenShift can be installed on Red Hat Enterprise Linux and Red Hat Enterprise Linux Atomic Host. The rollouts for Kubernetes involve installers like Rancher Kubernetes Everywhere (RKE). On the other hand, OpenShift utilizes an Ansible-based installer that requires minimal configuration parameters. <\/span><\/p>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Web User Interface<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Another prominent difference point between OpenShift and Kubernetes comes up in terms of the web user interface. The ability for cluster administration through the web UI is different for OpenShift and Kubernetes. The dashboard of Kubernetes needs separate installation while OpenShift provides a login page and easy access to its web console. <\/span><\/p>\n<table class=\"t1\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td class=\"td6\" valign=\"top\">\n<p class=\"p1\"><span class=\"s1\"><b>Criteria<\/b><\/span><\/p>\n<\/td>\n<td class=\"td6\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\"><b>Kubernetes<\/b><\/span><\/p>\n<\/td>\n<td class=\"td6\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\"><b>OpenShift<\/b><\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td7\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\"><b>Definition<\/b><\/span><\/p>\n<\/td>\n<td class=\"td7\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\">Container orchestration platform<\/span><\/p>\n<\/td>\n<td class=\"td7\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\">Containerization technology <\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td8\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\"><b>Features<\/b><\/span><\/p>\n<\/td>\n<td class=\"td8\" valign=\"top\">\n<ul class=\"ul1\">\n<li class=\"li2\"><span class=\"s1\">Reliable container deployment<\/span><\/li>\n<li class=\"li2\"><span class=\"s1\">High availability<\/span><\/li>\n<\/ul>\n<\/td>\n<td class=\"td8\" valign=\"top\">\n<ul class=\"ul1\">\n<li class=\"li2\"><span class=\"s1\">Centralized policy management<\/span><\/li>\n<li class=\"li2\"><span class=\"s1\">In-built security evaluations<\/span><\/li>\n<li class=\"li2\"><span class=\"s1\">Compatibility with Kubernetes workloads<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td9\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\"><b>Platform for Usage<\/b><\/span><\/p>\n<\/td>\n<td class=\"td9\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\">Linux Distribution OS<\/span><\/p>\n<\/td>\n<td class=\"td9\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\">Red Hat Enterprise Linux or Red Hat Enterprise Linux Atomic Host<\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td class=\"td7\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\"><b>Web UI<\/b><\/span><\/p>\n<\/td>\n<td class=\"td7\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\">Separate installation of dashboard for Kubernetes<\/span><\/p>\n<\/td>\n<td class=\"td7\" valign=\"top\">\n<p class=\"p2\"><span class=\"s1\">Facility of login page and ease access to web console<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<blockquote><p>Ansible and Terraform are the two names that are prominent in the DevOps landscape now.

Now, our focus should turn towards finding out the hidden relation between these three tools. Many developers and generally us till now did not understand the scope of any form of a relation between these three tools. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">You could not use knowledge about one platform when working with another platform. Furthermore, the lack of awareness about OpenShift vs Kubernetes vs Docker is also responsible for the lack of clarity about the boundaries of the platforms. Even if they appear unrelated, you can learn to apply the functionalities of one in the other. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">First of all, you should understand that Docker has certain limitations. Enterprise applications don\u2019t do very well with Docker and can involve various microservices. Based on the selected data management pattern, the microservices communicate with each other. Complex applications can require multiple containers, thereby leading to challenges for developers. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Now, here the next entrant in the discussion on OpenShift vs Kubernetes vs Docker arrives on the scene! Kubernetes lends a supporting hand to Docker with the facility of containers. Kubernetes is the ideal instrument for coordinating many clusters of nodes at the production level. Users can install docker on various nodes termed as Docker hosts. The hosts can either be bare-metal servers or other virtual machines. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">As we have seen above, Kubernetes uses its basic features for effective container orchestration. It can help in running containers across multiple machines, scaling containers, and distributing load across different containers. Also, Kubernetes ensures storage management for multiple container instances and the launch of new container instances. Simple words would say, docker is for creating, running, and managing a few containers, and Kubernetes is the magic trick. It multiplies the capabilities of Docker by many times. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">However, the most confusing aspect related to OpenShift vs Kubernetes vs Docker arises in terms of the role of OpenShift! The most prominent answer is that OpenShift depends on Docker and Kubernetes internally. You can also think of OpenShift as a Kubernetes distribution managed by Red Hat. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Even if the comparison between OpenShift and Kubernetes lead to many points of differences, they complement each other. The additions in OpenShift provide a legible course of improvement over Kubernetes and can revise conventional notions of container orchestration. So, the possibility of an intertwined <a href=\"https:\/\/www.whizlabs.com\/blog\/top-devops-tools\/\" target=\"_blank\" rel=\"noopener noreferrer\">DevOps tools<\/a> suite cannot be underscored here.<\/span><\/p>\n<blockquote><p>Kubernetes is the most popular container orchestration solution with DevOps. Let&#8217;s understand <a href=\"https:\/\/www.whizlabs.com\/blog\/devops-kubernetes-perfect-match\/\" target=\"_blank\" rel=\"noopener noreferrer\">how Kubernetes and DevOps toegther make a perfect match<\/a>!<\/p><\/blockquote>\n<h4 class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">Conclusion<\/span><\/h4>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">After the debate on OpenShift vs Kubernetes vs Docker, we can note the hidden relation between them. The symbiotic relationship between these three tools leaves little for comparison. On the contrary, we should try out new ways of implementing them in unison with each other. For example, Kubernetes can address various issues in Docker-only setup, and OpenShift could do the same for Kubernetes. <\/span><\/p>\n<p class=\"p1\" style=\"text-align: justify;\"><span class=\"s1\">The future course of action for your business depends a lot on the stage of <a href=\"https:\/\/www.whizlabs.com\/blog\/devops-introduction\/\" target=\"_blank\" rel=\"noopener noreferrer\">DevOps<\/a> adoption you are in. Newly inducted businesses could use the opinionated and guided support of OpenShift. On the other hand, experienced DevOps teams could make the most of Kubernetes. And at the end of it all, Docker is always there to give the best of containerization!<\/span><\/p>\n<p class=\"p2\" style=\"text-align: justify;\"><span class=\"s1\"><span class=\"Apple-converted-space\">If you are a DevOps professional working on any of the OpenShift, Kubernetes, and Docker, you should validate your skills with a certification.
