This repositroy contains materials for basic Kubernetes functionalities tutorial

To use files in repository, following requirements must be fulfilled:

1. Docker
2. Minikube
3. Helm

To configure cluster:

1. make start-minikube CIDR=<CIDR>, host must be able to connect to minikube VM on this network! (Default 192.168.99.0/24)
2. helm init
3. make build

Take a look at my-app/values.yaml, make sure that IP is correct there (it should point to host). In Makefile some targets are configured to ease maintenance.

  copy_file_to_pod
  port_forward
  scale_deployment
  set_docker_image

Each script is delivered with CLI usage help.
