Setup Terraform on Azure

Signup on Azure Cloud
Download azure-cli for your OS
Run az login and follow the prompt
Verify you can see the subscription plans
Install the terraform plugin for your OS
Run Terraform init
Run Terraform apply

Setup and create example Helm chart on Mac

run brew install Helm
Create a helm-chart folder
cd into the created directory run helm create
run helm lint
run helm package
Once the terraform blob storage has been deployed run helm repo index --url .

Upload Helm Chart to Blob Storage

export AZURE_STORAGE_ACCOUNT=$blobStoreName
export AZURE_STORAGE_KEY=$(az storage account keys list --resource-group $rg --account-name $blobStoreName | grep -m 1 value | awk -F'"' '{print $4}')
az storage blob upload --container-name $containerName --file index.yaml --name index.yaml
az storage blob upload --container-name $containerName --file *.tgz --name *.tgz

Thought Process

I wanted to make the blob storage as secure as possible by making use of a sas token on the url of the blob container, the helm chart was a bit manual in uploading, as I didn't see any plugin for the helm chart plugin for azure

Contributions

Todo:

Create a more unique storage account name that fits the description of the name requirement
Write a script to automate the uploading of the helm chart to the blob storage

Challenges

Getting to use the sas token was a bit of an hassle, also creating the subnets within the required virtual network kept on throwing some errors, I was reinitializing a variable that was been passed to the aks module twice, so fixed that, and everything worked out fine.
