# Deploy
|
|
|
|
### Requirements
|
|
1. Python
|
|
2. Pip
|
|
3. Pipenv
|
|
5. Nodes already deployed and running with ubuntu.
|
|
6. SSH access to all nodes you're deploying to.
|
|
* You will need to define an environment variable for your ssh key. `export PRIVATE_KEY="/location/of/key"`
|
|
|
|
### Steps
|
|
1. Copy hosts.example to hosts
|
|
* Name the node and under ansible_host put the ip of the node.
|
|
* Master nodes run the control plane. See kubernetes documentation for more info on masters: https://kubernetes.io/docs/concepts/overview/components/
|
|
* Workers are nodes used for running containers.
|
|
2. Copy group_vars/all.example to group_vars/all
|

|
3. Run `bash supporting-scripts/run-setup.sh`

# Lab environment
|
|
|
|
You can easily run a lab environment with Vagrant.
|
|
|
|
### Requirements
|
|
1. Install [Virtualbox](https://www.virtualbox.org/)
|
|
2. Install [Vagrant](https://www.vagrantup.com/)
|
|
|
|
### Steps
|
|
1. Run `vagrant up` - This will deploy 5 machines. A "client" node for running the deploy with ansible. A master node and 3 worker nodes.
|
|
2. Run `vagrant ssh client -c 'bash /vagrant/tests/files/test-deploy.sh'`
|
|
3. Run `vagrant ssh master` then run `kubectl` commands like `kubectl get nodes` or `kubectl get pods --all-namespaces`
|
|
4. Kubernetes nodes will be running on a host-only network that you can access from your machine with ips 192.168.254.2-5.
|
|
|
|
To see what is going on, this has deployed Traefik as an ingress controller to kubernetes. To get Traefik's port, run `kubectl get services -n kube-system` on the master. Then navigate to http://192.168.254.2:traefikport on your browser.
|
|
|
|
To destroy these machines, run `vagrant destroy -f`.
