7 Best Docker Container Cluster Orchestration Tools

Docker is undoubtedly an excellent open source tool. However, complex application deployment cannot be done with the docker engine and container alone. Container clusters that deploy complex application architectures must be properly configured. Containerized applications should be able to scale up and down based on application resource requirements.

We need a good framework for effective container management. The life cycle of the container is very short. The main factors to consider when orchestrating the container are

networking
High availability
Easy to deploy
Good service found.
1.Kubernetes
Kubernetes is an open source, out-of-the-box container cluster manager and business process. It has an excellent build scheduler and resource manager for deploying containers in a more efficient and highly available manner. Kubernetes has become the de facto container orchestration tool for many organizations. The kubernetes project is maintained by Google and contributors around the world. It provides many features not provided by native Docker tools. Moreover, using kubernetes is easy to get started.

2.OpenShift
Openshift is built on kubernetes. The Openshift project is maintained by Redhat. It has both open source (openshift orgin) and enterprise version (openshift container platform). Together with the core Kubernetes functions, it provides out-of-the-box components for container management and orchestration.

3. Docker Swarm
The Docker ecosystem includes tools from development to production deployment framework. In this list, docker swarm is suitable for cluster management. You can use a combination of docker-compose, swarm, overlay network, and good service discovery tools (such as etcd or consul) to manage the Docker container cluster.

Compared with other open source container cluster management tools, Docker swarm is still mature in terms of functionality. Considering the huge number of Docker contributors, it won’t be long before Docker swarm has all the best features that other tools have. Docker has documented a good production plan for using docker swarm in production.

4. Mesos
Mesos is another cluster management tool that can manage container orchestration very efficiently. It was created by Twitter for its infrastructure, and then it became open source. It has been used by companies such as eBay and Airbnb. Mesos is not a special tool for containers,

Mesos is not a dedicated tool for containers. Instead, you can use it for VMs or physical machine clusters to run workloads (big data, etc.) other than containers. It has an effective framework called Marathon for deploying and managing containers on Mesos clusters.

You can actually run a Kubernetes cluster on a Mesos cluster. Check this guide for the same content

5.Alibaba Cloud Resource Orchestration Service
Alibaba Cloud Resource Orchestration Service (ROS) provides developers and system managers with a simple method to create and manage their Alibaba Cloud resources. Through ROS you can use text files in JSON format to define any required Alibaba Cloud resources, dependencies between resources, and configuration details.

6. Digital Ocean Kubernetes service
Digital Ocean provides managed kubernetes services for deployment based on container applications. You can get $100 free points from Digital Ocean

7. Red Hat OpenShift online
Openshift Online is one of Redhat's PaaS products. You can use this service to deploy applications on the cloud through openshift. You do not have to manage the cluster because it is a pure PaaS service.

Choosing a tool or service depends entirely on your needs and the complexity of the application. There is no doubt that many organizations use the above tools and services for their production workloads.
