# configuring juju for azure 

We can first check that juju supports azure through the following command: 

```
juju show-cloud azure
```

We can also update the list of clouds juju has available using the following command:

```
juju update-clouds
```

The azure CLI tool needs to be installed using the following command. You may want to download and review the script first for security reasons rather than piping directly into bash: 

```
 curl -L https://aka.ms/InstallAzureCli | bash
```

If this does not work, try installing through apt: 

```
# first we setup the apt for the repos
AZ_REPO=$(lsb_release -cs)
echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $AZ_REPO main" | \
     sudo tee /etc/apt/sources.list.d/azure-cli.list

#  Install the azure-ci packages
sudo apt-key adv --keyserver packages.microsoft.com --recv-keys 52E16F86FEE04B979B07E28DB02C46DF417A0893
sudo apt-get install apt-transport-https
sudo apt-get update && sudo apt-get install azure-cli
```

During the script, your path is updated and your terminal should be restarted:

```
exec -l $SHELL
```

After this has been installed, you can verify the installation it using the command: 

```
 az --version
```

The next step is to add the azure credential to juju so we can use it to provision infrastructure: 

```
juju add-credential azure
Enter credential name: cpe-azure

Auth Types
  interactive
  service-principal-secret

Select auth type [interactive]: 

Enter subscription-id (optional):

  {
    "cloudName": "AzureCloud",
    "id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
    "isDefault": true,
    "name": "Pay-As-You-Go",
    "state": "Enabled",
    "tenantId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
    "user": {
      "name": "[email protected]",
      "type": "user"
    }
  }
]
Credentials added for cloud azure.
```

**__Note that credentials may expire after some time and should be renewed if problems arise with juju when you use Azure.__**

The next step is to bootstrap Azure, change 'mycloud' to something more meaningful, this will be the name of the contoller node on azure: 

```
  juju bootstrap azure mycloud
  juju bootstrap azure mycloud
Creating Juju controller "mycloud" on azure/centralus
Looking for packaged Juju agent version 2.3.4 for amd64
Launching controller instance(s) on azure/centralus...

Bootstrap agent now started
Contacting Juju controller at 192.168.16.4 to verify accessibility...
Bootstrap complete, "mycloud" controller now available
Controller machines are in the "controller" model
Initial model "default" added
```

Once we have the controller node, we are ready to deploy Kubernetes:

```
 juju deploy canonical-kubernetes
```

Or if you have a bundle file: 

```
 juju deploy bundle.yaml
```

Finally, you can check the status using: 

```
 juju status 
```

or 

```
 watch --color juju status --color
```
