This project contains:
- two (really) micro services, hello-micro-service and world-micro-service. Both are written in Go;
- Dockerfiles for both microservices, both have been pushed to Dockerhub;
- Kubernetes yaml config files to create a deployment and service;
- A
setup.shscript that runs uses the yaml to set up the deployment, pods and a service.
The hello-micro-service runs on port 8080 and has two endpoints. /hello simply return "Hello", /hello-world returns "Hello world!" by concatenating "Hello" to the result of the endpoint on world-micro-service.
The world-micro-service runs on port 8081 and has one endpoint. /world simply returns " world!".
The yaml configures two replica pods containing both microservices, a deployment to manage the pods and a service to load balance to the pods and provide an access point to the application: the IP of the Node on port 30500.
Once you have installed Docker and Minikube, run setup.sh, this will set everything up. Note: it may take a few mins for everything to come to life.
You can run curl $(minikube ip):30500/helloworld to vertify it all works, the output should be: "Hello world!"
