Kubernetes deployment excercise. This is a project of Udacity Cloud DevOps Nanodegree

DevOps_docker

Repository used for docker project of Udacity Cloud DevOps Nanodegree.

Steps

1. Make the Dockerfle
2. Run container & make prediction and make log

The log of the prediction is as below

3. Update the Docker Image

   • Go to ECR, and create a repository (if not exist)
   • Retrieve an authentication token and authenticate the Docker client aws ecr get-login --no-include-email --region us-east-1
   • Paste and run the token on the command line to certificate (long token, copy and paste)
   • run bash upload_docker.sh

4. Configure Kubernetes to run locally

   • Setup minikube
     • install from here https://kubernetes.io/docs/tasks/tools/install-minikube/
     • minikube start (for Windows10, not on bash, but on PowerShell)
     • minikube stop
   • To check: kubectl config view

5. Deploy the cluster online

   • Setup kubectl
     • sudo apt-get update && sudo apt-get install -y apt-transport-https
     • curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
     • echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list
     • sudo apt-get update
     • sudo apt-get install -y kubectl
   • Run bash run_kubenetes.sh to run kubernetes cluster (this may take several minutes)

6. Make prediction

   • Run make_prediciton.sh on another terminal. Results are following
