Lab Replay

Replay this lab at home by following easy steps:

1. Register free account on Docker Hub: https://hub.docker.com/

3. Download this repository (green button in top right corner of github page)
4. Edit azuredeploy.parameters.json and insert your servicePrincipalClientId and servicePrincipalClientSecret (sshRSAPublicKey will be auto-generated)
5. Install Azure kubernetes cluster with provided deploy script
6. Check your cluster IP address with ```az acs list'''
7. Login onto "developement" VM: ssh -i .ssh/az_acs azureuser@...
   1. We will use example Wordpress (app+database) docker set: cd examples/wordpress
   2. Examine set of containers (container.yml) and provided ansible playbook (main.yml)
   3. First we build our images: ansible-container build
   4. Now we can run them (interactively, or with -d option - in backgroud): ansible-container run [-d]
   5. (Point your browser to http://YOUR-ACS-INSTANCE and play with Wordpress demo)
   6. Login from your developement to Docker Hub: docker login
   7. Push your applications to Docker Hub: ansible-container push
   8. Examine pushed images (check "Tags" tab) on Docker Hub: https://hub.docker.com/
   9. Create production-ready recipes for Kubernetes ansible-container shipit kube --save-config
   10. Create services: kubectl create -f ansible/shipit_config/kubernetes/
   11. Get pods information: kubectl get pods
   12. Notice how application and database images has been pulled from Docker Hub repository.
   13. Get instance information (Your instance ID will differ slightly): kubectl describe pod wordpress-...
   14. Get services information: kubectl get service wordpress
   15. Connect to the external IP of your wordpress (either with ssh dynamic port forwarding or plain curl -sL)
8. Once complete cleanup your lab environment: az group delete --name ... --yes
