#### Azure Managed Identity
Azure managed identity service allows linking Azure AD identities to Azure resources. \
Workloads running inside compute typed resource can inherit from this configuration to get rights on Azure resources.
The Azure Managed Identity service allows linking Azure AD identities to Azure resources, without needing to manually manage client IDs and secrets.
Workloads with a Managed Identity can manage their own certificates, with permissions on specific domain names set using IAM assignments.
For this to work, the Managed Identity requires the **Reader** role on the target DNS Zone,
and the **DNS Zone Contributor** on the relevant `_acme-challenge` TXT records.
For example, to allow a Managed Identity to create a certificate for "fw01.lab.example.com", using Azure CLI:
```bash
export AZURE_SUBSCRIPTION_ID="00000000-0000-0000-0000-000000000000"
export AZURE_RESOURCE_GROUP="rg1"
export SERVICE_PRINCIPAL_ID="00000000-0000-0000-0000-000000000000"
export AZURE_DNS_ZONE="lab.example.com"
export AZ_HOSTNAME="fw01"
export AZ_RECORD_SET="_acme-challenge.${AZ_HOSTNAME}"
az role assignment create \
--assignee "${SERVICE_PRINCIPAL_ID}" \
--role "Reader" \
--scope "/subscriptions/${AZURE_SUBSCRIPTION_ID}/resourceGroups/${AZURE_RESOURCE_GROUP}/providers/Microsoft.Network/dnszones/${AZURE_DNS_ZONE}"
az role assignment create \
--assignee "${SERVICE_PRINCIPAL_ID}" \
--role "DNS Zone Contributor" \
--scope "/subscriptions/${AZURE_SUBSCRIPTION_ID}/resourceGroups/${AZURE_RESOURCE_GROUP}/providers/Microsoft.Network/dnszones/${AZURE_DNS_ZONE}/TXT/${AZ_RECORD_SET}"
```
#### Azure Managed Identity (with Azure Arc)
The Azure Arc agent provides the ability to use a Managed Identity on resources hosted outside of Azure
(such as on-prem virtual machines, or VMs in another cloud provider).
While the upstream `azidentity` SDK will try to automatically identify and use the Azure Arc metadata service,
if you get `azuredns: DefaultAzureCredential: failed to acquire a token.` error messages,
you may need to set the environment variables:
* `IMDS_ENDPOINT=http://localhost:40342`
* `IDENTITY_ENDPOINT=http://localhost:40342/metadata/identity/oauth2/token`
#### Workload identity for AKS
Workload identity allows workloads running Azure Kubernetes Services (AKS) clusters to authenticate as an Azure AD application identity using federated credentials. \
This must be configured in kubernetes workload deployment in one hand and on the Azure AD application registration in the other hand. \

Here is a summary of the steps to follow to use it :
* create a `ServiceAccount` resource, add following annotations to reference the targeted Azure AD application registration : `azure.workload.identity/client-id` and `azure.workload.identity/tenant-id`. \
* create a `ServiceAccount` resource, add following annotations to reference the targeted Azure AD application registration : `azure.workload.identity/client-id` and `azure.workload.identity/tenant-id`.
* on the `Deployment` resource you must reference the previous `ServiceAccount` and add the following label : `azure.workload.identity/use: "true"`.
* create a fedreated credentials of type `Kubernetes accessing Azure resources`, add the cluster issuer URL and add the namespace and name of your kubernetes service account.
