Difference between docker swarm, kubernetes and openshift
In this post, i will describe the difference between docker swarm, kubernetes and openshift:
| Docker Swarm | Kubernetes | Openshift |
| Easy and fast setup | Open source and modular | Manages kubernetes |
| Works with other existing docker tools | Runs on any Linux OS | Helps abstract kubernetes limitation such as network features |
| Lightweight installation | Easy service organisation with pods | Red hat OS (except for dev) is mandatory |
| Open source | Backed by years of expert experience | Security feature are better managed than in kubernetes |
| Limited functionalities with the Docker API | Laborious install and configuration | Smaller community than Kubernetes one |
| Updates for swarm must be schedules | Updates for kubernetes are monitored and controlled progressively | Openshift lets kubernetes handel the updates |
| Limited fault tolerance | Incompatible with docker cli and docker compose |
