Azure¶

Azure provider requires you to input clientsecret, subscriptionid, tenantid, and clientid.

Compute and DNS example¶

apiVersion: v1
kind: Secret
metadata:
  name: azure-secret
data:
  clientid: QWJjZH5FRmd+SDZJamtsc35BQkMxNXNFRkdLNTRzNzhYfk9sazk=
  # all resources you define will be charged here
  clientsecret: NmE0ZGZzZzctc2Q0di1mNGFkLWRzdmEtYWQ0djYxNmZkNTEy
  subscriptionid: NTRjZGFmYTUtc2R2cy00NWRzLTU0NnMtZGY2NTFzZmR0NjE0
  tenantid: MDI1NXNjMjMtNzZ3ZS04N2c2LTk2NGYtYWJjMWRlZjJnaDNs
type: Opaque

Create Azure credentials¶

Prerequisites¶

Install Azure CLI by following this guide.
Login to Azure this guide.

Creating Azure credentials for Claudie¶

Login to Azure with the following command:
```
az login
```

Permissions file for the new role that claudie service principal will use:

cat > policy.json <<EOF
{
   "Name":"Resource Group Management",
   "Id":"bbcd72a7-2285-48ef-bn72-f606fba81fe7",
   "IsCustom":true,
   "Description":"Create and delete Resource Groups.",
   "Actions":[
      "Microsoft.Resources/subscriptions/resourceGroups/write",
      "Microsoft.Resources/subscriptions/resourceGroups/delete"
   ],
   "AssignableScopes":["/"]
}
EOF

Create a role based on the policy document:

az role definition create --role-definition policy.json

Create a service account to access virtual machine resources as well as DNS:

az ad sp create-for-rbac --name claudie-sp

{
  "clientId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "displayName": "claudie-sp",
  "clientSecret": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "tenant": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
}

Assign required roles for the service principal:

{
  az role assignment create --assignee claudie-sp --role "Virtual Machine Contributor"
  az role assignment create --assignee claudie-sp --role "Network Contributor"
  az role assignment create --assignee claudie-sp --role "Resource Group Management"
}

DNS requirements¶

If you wish to use Azure as your DNS provider where Claudie creates DNS records pointing to Claudie managed clusters, you will need to create a public DNS zone by following this guide.

Azure is not my domain registrar

If you haven't acquired a domain via Azure and wish to utilize Azure for hosting your zone, you can refer to this guide on Azure nameservers. However, if you prefer not to use the entire domain, an alternative option is to delegate a subdomain to Azure.

Input manifest examples¶

Single provider, multi region cluster example¶

Create a secret for Azure provider¶

The secret for an Azure provider must include the following mandatory fields: clientsecret, subscriptionid, tenantid, and clientid.

kubectl create secret generic azure-secret-1 --namespace=mynamespace --from-literal=clientsecret='Abcd~EFg~H6Ijkls~ABC15sEFGK54s78X~Olk9' --from-literal=subscriptionid='6a4dfsg7-sd4v-f4ad-dsva-ad4v616fd512' --from-literal=tenantid='54cdafa5-sdvs-45ds-546s-df651sfdt614' --from-literal=clientid='0255sc23-76we-87g6-964f-abc1def2gh3l'
