Packet Host
|
||||
===============
|
||||
|
||||
Kubespray provides support for bare metal deployments using the [Packet Host bare metal cloud](http://www.packet.com).
|
||||
Deploying upon bare metal allows Kubernetes to run at locations where an existing public or private cloud might not exist such
|
||||
as cell tower, edge collocated installations. The deployment mechanism used by Kubespray for Packet is similar to that used for
|
||||
AWS and OpenStack clouds (notably using Terraform to deploy the infrastructure). Terraform uses the Packet provider plugin
|
||||
to provision and configure hosts which are then used by the Kubespray Ansible playbooks. The Ansible inventory is generated
|
||||
dynamically from the Terraform state file.
|
||||
|
||||
## Local Host Configuration
|
||||
|
||||
To perform this installation, you will need a localhost to run Terraform/Ansible (laptop, VM, etc) and an account with Packet Host.
|
||||
In this example, we're using an m1.large CentOS 7 OpenStack VM as the localhost to kickoff the Kubernetes installation.
|
||||
You'll need Ansible, Git, and PIP.
|
||||
|
||||
```bash
|
||||
sudo yum install epel-release
|
||||
sudo yum install ansible
|
||||
sudo yum install git
|
||||
sudo yum install python-pip
|
||||
```
|
||||
|
||||
## Playbook SSH Key
|
||||
|
||||
An SSH key is needed by Kubespray/Ansible to run the playbooks.
|
||||
This key is installed into the bare metal hosts during the Terraform deployment.
|
||||
You can generate a key new key or use an existing one.
|
||||
|
||||
```bash
|
||||
ssh-keygen -f ~/.ssh/id_rsa
|
||||
```
|
||||
|
||||
## Install Terraform
|
||||
|
||||
Terraform is required to deploy the bare metal infrastructure. The steps below are for installing on CentOS 7.
|
||||
[More terraform installation options are available.](https://learn.hashicorp.com/terraform/getting-started/install.html)
|
||||
|
||||
Grab the latest version of Terraform and install it.
|
||||
```bash
|
||||
echo "https://releases.hashicorp.com/terraform/$(curl -s https://checkpoint-api.hashicorp.com/v1/check/terraform | jq -r -M '.current_version')/terraform_$(curl -s https://checkpoint-api.hashicorp.com/v1/check/terraform | jq -r -M '.current_version')_darwin_amd64.zip"
|
||||
sudo yum install unzip
|
||||
sudo unzip terraform_0.11.11_linux_amd64.zip -d /usr/local/bin/
|
||||
```
|
||||
|
||||
## Download Kubespray
|
||||
|
||||
Pull over Kubespray and setup any required libraries.
|
||||
|
||||
```bash
|
||||
git clone https://github.com/kubernetes-sigs/kubespray
|
||||
cd kubespray
|
||||
sudo pip install -r requirements.txt
|
||||
```
|
||||
|
||||
## Cluster Definition
|
||||
|
||||
In this example, a new cluster called "alpha" will be created.
|
||||
|
||||
```bash
|
||||
cp -LRp contrib/terraform/packet/sample-inventory inventory/alpha
|
||||
cd inventory/alpha/
|
||||
ln -s ../../contrib/terraform/packet/hosts
|
||||
```
|
||||
|
||||
Details about the cluster, such as the name, as well as the authentication tokens and project ID
|
||||
for Packet need to be defined. To find these values see [Packet API Integration](https://support.packet.com/kb/articles/api-integrations)
|
||||
|
||||
```bash
|
||||
vi cluster.tf
|
||||
```
|
||||
* cluster_name = alpha
|
||||
* packet_project_id = ABCDEFGHIJKLMNOPQRSTUVWXYZ123456
|
||||
* public_key_path = 12345678-90AB-CDEF-GHIJ-KLMNOPQRSTUV
|
||||
|
||||
## Deploy Bare Metal Hosts
|
||||
|
||||
Initializing Terraform will pull down any necessary plugins/providers.
|
||||
|
||||
```bash
|
||||
terraform init ../../contrib/terraform/packet/
|
||||
```
|
||||
|
||||
Run Terraform to deploy the hardware.
|
||||
|
||||
```bash
|
||||
terraform apply -var-file=cluster.tf ../../contrib/terraform/packet
|
||||
```
|
||||
|
||||
## Run Kubespray Playbooks
|
||||
|
||||
With the bare metal infrastructure deployed, Kubespray can now install Kubernetes and setup the cluster.
|
||||
|
||||
```bash
|
||||
ansible-playbook --become -i inventory/alpha/hosts cluster.yml
|
||||
```
