Automatic Service Discovery and Routing for Microservices with Mule, Docker, Consul, and Fabio Summary In this example we’re going to create a single host micro-services architecture with automatic service discovery and routing as containers scale vertically across the host. Kubenetes ingress acts in a similar way except the routing rules will be maintained as Kubernetes ingress object. yml file expects an image by the name of reverseproxy so that is what we're building. This schema represents kubernetes internal components after the kargo install. Docker is the most popular file format for Linux-based container development and deployments. AND the service cannot be controlled with the Windows Docker client as the Windows client enforces swarm services and non-swarm services (especially including their networks) to be mutually exclusive. This ensures that the latest image is always available in Docker Hub for continuous deployment to production. Before we begin the tutorial, which will cover installing HAProxy for load balancing, let’s first talk about the concept of load balancing. Why I don't use Docker much anymore 11 Mar 2015 17 minute read. Zevenet support L3, L4, and L7.
