Docker Swarm is the native clustering engine by and for Docker. It is all about managing a cluster of Docker engines.
Any tools, services or software that works with containers with Docker run equally well in Docker Swarm.
Kubernetes is a popular open-source container storage program. It was built by Google to manage their own systems. Kubernetes is an open-source, scalable, useful and powerful tool. It can handle containers and offer immense scalability and automation at the same time.
Following are some of the differentiating points of both the technologies.
Installation
Docker wins hands-down when it comes to setup and installation.
The Docker Swarm uses CLI and GIT-like semantics. This makes it easy for application developers to incorporate new technologies into their workflow. So with Docker Swarm, you don't need to learn new things when implementing the container for new OS or environment.
On the other hand, when it comes to installation and setup of Kubernetes, it can give developers a nightmare.
There is an online documentation available that can help a lot in the process.
Kubernetes require a lot of planning before implementation begins. Planning the nodes that takes a lot of time and effort. Not everything can be automated, and that makes Kubernetes hard to manage.
Usage
Docker swarm is early in development/launch cycle hence is not recommended for business-critical applications just yet. It will improve and mature with time.
On the other hand, Kubernetes is production ready and enterprise grade. It has been used by a lot of companies in production at scale.
Monitoring
For Kubernetes, there is more than one way to monitor and log the clusters. You can use any of the following ways to do so:
- Logging: Kibana (ELK) or Elasticsearch
- Monitoring: Grafana, Heapster, or Influx
For Docker, there is no in-built library or process for monitoring or logging. However, developers can use third-party applications for monitoring and logging purposes.
Conclusion
Docker may have the potential to stand next to Kubernetes in terms of technology. However, Kubernetes is widely accepted by the community of developers, despite the hard installation process. The sole reason behind its popularity is the flexibility it offers and also the fact that it is backed by Google, one of the leading tech giants. Docker, on the other hand, has a small community.
