Containers let you package application code/binary as well as its dependencies such as file system, registry, and network. Advantages include consistency across development, test, and production.

Orchestration tools

Using containers in production requires management and infrastructure features:

  • Container cluster deployment and management
  • Scheduling and automation
  • Container placement and management
  • Service discovery and networking
  • Monitoring and logging

The technologies that provide these services are known as container orchestrators. There are two major open source container orchestration technologies available:

  • Docker Swarm — cluster management integrated with the Docker Engine including scaling, load balancing, and service discovery
  • Kubernetes — automated deployment, scaling, and management of containerized applications

Additional technologies are available including Ansible for configuration management and provisioning, Grafana for monitoring and analytics, and Kibana for analytics and visualization. Only Kubernetes is tightly bound to containers.
