     1  ## Introduction
     2  
     3  These terraform definitions are going to create the whole
     4  cluster on KVM via terraform-provider-libvirt.
     5  
     6  ## Prerequisites
     7  
     8  Follow instructions at https://github.com/dmacvicar/terraform-provider-libvirt#installing to install terraform-provider-libvirt.
     9  
    10  ## Deployment
    11  
    12  Use `terraform` to deploy the cluster. `-parallelism=1` used in apply command avoids potential concurrent issues in terraform-provider-libvirt.
    13  
    14  ```sh
    15  terraform init
    16  terraform apply -parallelism=1
    17  ```
    18  
    19  ## Machine access
    20  
    21  It is important to have your public ssh key within the `authorized_keys`, this is done by `cloud-init` through a terraform variable called `authorized_keys`.
    22  
    23  All the instances have a `sles` user, password is not set. User can login only as `sles` user over SSH by using his private ssh key. The `sles` user can perform `sudo` without specifying a password.
    24  
    25  ## Load balancer
    26  
    27  The kubernetes api-server instances running inside of the cluster are
    28  exposed by a load balancer managed by OpenStack.
    29  
    30  ## Customization
    31  
    32  IMPORTANT: Please define unique `stack_name` value in `terrafrom.tfvars` file to not interfere with other deployments.
    33  
    34  Copy the `terraform.tfvars.example` to `terraform.tfvars` and provide reasonable values.
    35  
    36  ## Variables
    37  
    38  `libvirt_uri` - URL of the libvirt host
    39  `libvirt_keyfile` - The key file used for the connection to a remote libvirt server
    40  `image_uri` - URL of the image to use
    41  `stack_name` - Identifier to make all your resources unique and avoid clashes with other users of this terraform project
    42  `authorized_keys` - A list of ssh public keys that will be installed on all nodes
    43  `repositories` - Additional repositories that will be added on all nodes
    44  `packages` - Additional packages that will be installed on all nodes
    45  
    46  ### Please use one of the following options:
    47  `caasp_registry_code` - Provide SUSE CaaSP Product Registration Code in `registration.auto.tfvars` file to register product against official SCC server  
    48  `rmt_server_name` - Provide SUSE Repository Mirroring Tool Server Name in `registration.auto.tfvars` file to use repositories stored on RMT server
