This document covers setting up django-todo in minikube.

We will start our journey from local minikube installation.

1. The minikube_install.sh have some simple steps to get kubectl and minikube with kvm drivers.
2. Check and Run minikube.sh to deploy a VM with cluster (it's have some options about CPU and RAM).
3. At this point kubectl get ns should show you an empty cluster (only standart namespaces must be listed).

Now it's time for deployment

Entrypoint into deployment process is the deploy.sh. This file consists of few blocks:

1. docker build will create an image. There are some nuances:
   • The first of all os local.py. This file can be placed as a configMap too. Changes of the file are simple: os.environ for all the external keys and ALLOWED_HOSTS Django parameter. Not a good idea to set it to * for production.
   • The second one is entrypoint.sh. Script is quite simple, but you should know it is exist. Also, expression eval $(minikube docker-env) make some magic to put builded image into VM with minikube.
2. kubectl create secret... should be placed in vault or any other secrets storage. I'm simply have nothing.
3. This solution have https://github.com/helm/charts/tree/master/stable/postgresql as a dependency. Few notes about it:
   • Really bad idea to use not cluterized DBs in production.
   • No any backups.
   • We must fetch dependencies before the final helm install command.
4. sleep - you know...
5. minikube service todo - i decided to not add another dependencies, like nginx, instead of that Service type was changed to NodePort. Durty, but legal for local development. Also, there is a way to set exact port for NodePort, but now is about 2AM.

Pretty much that's it! Of course there are so many things to improve...

• deployment.yaml template was changed a little...
• There are no tests. Bad, i know.
• Better to use dedicated namespace instead of default..
• Sometimes github can ban users, better to impletment API key for github auth in Dockerfile...
• It's also possible to add teraform via local-exec provider for minikube_install.sh but it's almost pointless...

Maybe, i miss something...

Tested with:

• Kubernetes v1.17.2 in minikube
• helm v302
• Ubuntu 19.10
