#Helm charts for the AKS learning series

There are 3 charts available in this repo.

1. Chart for sqlserver helm/database. This chart uses Kubernetes Secrets to stash the secrets. The values.yaml contains the secret in base64 encoded format.

   replicaCount: 1
   image:
     repository: microsoft/mssql-server-linux
     tag: latest
     pullPolicy: IfNotPresent
     restartPolicy: Always
     terminationGracePeriodSeconds: 30
     dnsPolicy: ClusterFirst
   
   service:
     type: ClusterIP
     internalPort: 1433
   
   secrets:
     sapassword: SmFudWFyeTIwMTg=
         
   

   Make sure replicas are set to 1. Currently this image does not support replicas more than 1.

   To install using helm, simply execute at the command prompt from helm/database/ directory.

   helm install --name <your release name> --namespace <your namespace> .

   Example.

   helm install --name db --namespace techtalks .. The . at the end specifies the current directory.

2. Chart for the api server. This chart installs the api server.

   replicaCount: 1
   image:
     repository: nileshgule/techtalksapi
     tag: latest
     pullPolicy: IfNotPresent
     restartPolicy: Always
     terminationGracePeriodSeconds: 30
     dnsPolicy: ClusterFirst
   
   initializer_image:
     repository: nileshgule/sqlclient
     tag: latest
   
   service:
     type: ClusterIP
     internalPort: 8080
   
   resources:
     limits:
       memory: 256Mi
       cpu: 1000m
     requests:
       memory: 128Mi
       cpu: 500m
   
   secrets:
     connectionString: RGF0YSBTb3VyY2U9ZGItZGVwbG95bWVudDtJbml0aWFsIENhdGFsb2c9VGVjaFRhbGtzREI7VXNlciBJZD1TQTtQYXNzd29yZD1KYW51YXJ5MjAxODtNdWx0aXBsZUFjdGl2ZVJlc3VsdFNldHM9VHJ1ZQ==
     dbPassword: SmFudWFyeTIwMTg=       
   
   

   Also noticed that the connectionString is base64 encoded, same as the dbPassword. Both are loaded into Kuberntes Secret.

   Please note that the service name is fixed to techtalksapi.

   TODO fix the hardcoded instance in the code.

   To install, from helm/techtalksapi/ directory

   helm install --name api --namespace techtalks .

3. Chart for the web frontend.

   replicaCount: 1
   image:
     repository: nileshgule/techtalksweb
     tag: latest
     pullPolicy: IfNotPresent
     restartPolicy: Always
     terminationGracePeriodSeconds: 30
     dnsPolicy: ClusterFirst
   
   service:
     type: NodePort
     internalPort: 80
   
   resources:
     limits:
       memory: 256Mi
       cpu: 1000m
     requests:
