OpenShift has a pre-integrated Jenkins framework so that it is easy to set up CI/CD. CI/CD Operationsįor CI/CD in Kubernetes and Docker, external extensions or tools such as Jenkins are supported and need to be installed separately.
OpenShift makes changes to its repository slightly after the release of Kubernetes, Docker and other open source platforms. Upgrades and PatchesĪt first, upgrades and patches are released by Kubernetes and Docker. OpenShift support all workload types be it docker images as it enclosed with Kubernetes. But Kubernetes handles Docker images as well as independent containers and provides a wide set of features equal to all workloads. Docker EE is suitable mostly for orchestrating Docker images as it is tightly integrated with Docker API for intercommunication. Workload Typesĭocker offers Docker EE for container management and orchestration. To help decision-makers to choose container management platforms, let’s put up more points that will showcase differences and relation between Docker, OpenShift and Kubernetes. Comparing Docker, OpenShift and Kubernetes For any glitches or support in implementation, Red Hat OpenShift offers a paid support. OpenShift is a solution by Red Hat built upon Kubernetes and Docker projects. Red Hat offers OpenShift platform as a service that is mainly powered by Kubernetes and includes Docker to manage the variety of workloads.
If you implement Kubernetes yourself within your infrastructure and some error arises, you must turn to the community for a solution. We know Kubernetes is a community project. Due to this, we can see a number of Kubernetes-as-a-service platforms offered by vendors of different scale. Kubernetes has enabled developers to accelerate the development of cloud-native applications and created an ecosystem of services that are self-driven and reusable. Kubernetes helps simplify container runtime by managing Docker-based applications that are placed on an underlying assures system that maintains several replicas of running applications. Features offered by Kubernetes are complementary to Docker. Where Docker EE is limited, Kubernetes provides the ability to run containers on various machines, auto-scale containers, distribute load between containers, manage storage required by containers, provide resiliency of containers in case of failure and more. Kubernetes is an open source container orchestration solution hosted by Cloud Native Computing Foundation (CNCF) and backed by Google, AWS, Microsoft, IBM, Intel, Cisco Systems and Red Hat. But Docker EE was not able to provide efficient scaling and external load balancing for images it was orchestrating. It was offered as a commercial product in the form of a Docker Enterprise Engine. Later, Docker Swarm was launched to handle orchestration and as schedulers for Docker images. The container concept came into focus when Docker crept into data centers of many private or public clouds. It is supported by its ecosystem to manage and run Docker container images with its dependencies. Dockerĭocker is container technology and a company-offered container image runtime. There are basically three choices for containerization: Docker, Kubernetes and OpenShift. Still, there are few hindrances CXOs or technology managers are facing regarding container solutions in terms of management, scaling, agile deployment and sustenance.
