+# Quick Docker build using identity and keyvault
+
+## Create a resource group
+
+```bash
+az group create \
+  -n mytaskrunrg \
+  -l westus
+```
+
+## Create a Registry
+
+```bash
+az acr create \
+   -n myreg -g mytaskrunrg --sku Standard
+```
+
+## Create a Custom Registry and enable the admin user
+
+```bash
+az acr create \
+   -n mycustomreg -g mytaskrunrg --sku Standard --admin-enabled true
+```
+
+## Create a User Identity
+
+```bash
+az identity create \
+  -g mytaskrunrg \
+  -n myquickdockerbuildrunwithidentity
+```
+
+## Create KeyVault
+
+```bash
+az keyvault create --name mykeyvault --resource-group mytaskrunrg --location eastus2

+
+## Save registry username/password in the keyvault
+
+```bash
+#Get password of admin user
