# Kubernetes on Azure with Azure Resource Group Templates
Provision the base infrastructure for a Kubernetes cluster by using [Azure Resource Group Templates](https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-authoring-templates)
## Status
This will provision the base infrastructure (vnet, vms, nics, ips, ...) needed for Kubernetes in Azure into the specified
Resource Group. It will not install Kubernetes itself, this has to be done in a later step by yourself (using kargo of course).
## Requirements
- [Install azure-cli](https://docs.microsoft.com/en-us/azure/xplat-cli-install)
- [Login with azure-cli](https://docs.microsoft.com/en-us/azure/xplat-cli-connect)
- Dedicated Resource Group created in the Azure Portal or through azure-cli
## Configuration through group_vars/all
You have to modify at least one variable in group_vars/all, which is the **cluster_name** variable. It must be globally
unique due to some restrictions in Azure. Most other variables should be self explanatory if you have some basic Kubernetes
experience.
## Bastion host
You can enable the use of a Bastion Host by changing **use_bastion** in group_vars/all to **true**. The generated
templates will then include an additional bastion VM which can then be used to connect to the masters and nodes. The option
also removes all public IPs from all other VMs.
## Generating and applying
To generate and apply the templates, call:
```shell
$ ./apply-rg.sh <resource_group_name>
```
If you change something in the configuration (e.g. number of nodes) later, you can call this again and Azure will
take care about creating/modifying whatever is needed.
## Clearing a resource group
If you need to delete all resources from a resource group, simply call:
```shell
$ ./clear-rg.sh <resource_group_name>
```
**WARNING** this really deletes everything from your resource group, including everything that was later created by you!
## Generating an inventory for kargo
After you have applied the templates, you can generate an inventory with this call:
```shell
$ ./generate-inventory.sh <resource_group_name>
```
It will create the file ./inventory which can then be used with kargo, e.g.:
```shell
$ cd kargo-root-dir
$ ansible-playbook -i contrib/azurerm/inventory -u devops --become -e "@inventory/group_vars/all.yml" cluster.yml
```

including resolvconf's base/head/cloud-init config files and those that come from dhclient.
This is required for hostnet pods networking and for [kubelet to not exceed search domains
limits](https://github.com/kubernetes/kubernetes/issues/9229).
New search, nameserver records and options will be defined from the aforementioned vars:
* Via resolvconf's head file, if resolvconf installed.
* Via dhclient's DNS update hook.
* Via cloud-init (CoreOS only).
* Statically in the `/etc/resolv.conf`, if none of above is applicable.
Instead, new domain, search, nameserver records and options will be defined from the
aforementioned vars:
* Superseded via dhclient's DNS update hook.
* Generated via cloud-init (CoreOS only).
* Statically defined in the `/etc/resolv.conf`, if none of above is applicable.
* Resolvconf's head/base files are disabled from populating anything into the
`/etc/resolv.conf`.
