As you may have noticed, Ansible and Docker address similar software deployment issues:
- Environment configuration: Both Ansible and Docker provide a way to configure the environment; however, they use different means. While Ansible uses scripts (encapsulated inside the Ansible modules), Docker encapsulates the whole environment inside a container.
- Dependencies: Ansible provides a way to deploy different services on the same or different hosts and let them be deployed together. Docker Compose has a similar functionality, which allows running multiple containers at the same time.
- Scalability: Ansible helps to scale services providing the inventory and host groups. Docker Compose has a similar functionality to automatically increase or decrease the number of running containers.
