# Flask Backend Application



This repository contains backend logic and kubernetes manifests. I have used `minikube` for this project. Installation steps is given in this [gist](https://gist.github.com/aliartiza75/3a34f059de62c7de04727dae6a363ea8)



# Guidelines for containerizing backend 



* To build image

```bash

sudo docker run -t ht-be:0.0.1 -f Dockerfile .

```



* To run docker container on host machine

```bash

sudo docker run -e FLASK_ENV=development -e FLASK_HOST_IP=0.0.0.0 -e=FLASK_HOST_PORT=5001 -e Name=Irtiza -p 1001:5001 ht-be:0.0.1

```



# Guidelines for kubernetes deployment



* Deployment creation

```bash

sudo kubectl apply -f deployment.yaml

```



* Service creation

```bash

sudo kubectl apply -f htbe_service.yaml 

```



* Validating whether application is running or not. Use the command given below from host machine on which kubernetes is running

```

curl -X GET "http://:/datetime"

```



# Guidelines for helm charts deployment

* Helm installation guidelines [link](https://helm.sh/docs/install/#installing-the-helm-client)



* Once the helm is installed, use the command given below to install tiller in kubernetes cluster:

```bash

helm init

```



* To create a helm chart folder:



```bash

helm create 

```



* To dry run the helm chart for debugging:

```bash

sudo helm install --dry-run --debug  

```



* To purge a release

```bash

sudo helm del --purge 

```



* To check the status of a release

```bash

sudo helm ls --all 

```



* To search a helm package name

```bash

sudo helm search 

```



* To create a package from the helm charts folder

```bash

sudo helm package 

```



# Important Notes

* Start the minikube cluster in the virtual machine drive in none mode [--vm-driver=none], otherwise services will not be accessible.

* Minikube will pull images from the dockerhub.

* In some cases minikube cluster doesn't work properly, one quick fix is to delete the cluster and restart the minikube cluster.
