DockerCon SF 2015: Interconnecting Containers at Scale w/ NGINX
6 likes5,046 views
The document discusses how NGINX can help with interconnecting microservices at scale using containers. It provides an example docker-compose configuration that sets up Consul for service discovery, Registrator to register services with Consul, and NGINX Plus to load balance requests across multiple containers and automatically generate its configuration from Consul. The live demo shows how scaling a service results in new containers being automatically registered with Consul and load balanced by NGINX.
