# Setting up Kubernetes
|
|
|
|
- How did we set up these Kubernetes clusters that we're using?
|
|
|
|
--
|
|
|
|
- We used `kubeadm` on freshly installed VM instances running Ubuntu 16.04 LTS
|
|
|
|
1. Install Docker
|
|
|
|
2. Install Kubernetes packages
|
|
|
|
3. Run `kubeadm init` on the master node
|
|
|
|
4. Set up Weave (the overlay network)
|
|
<br/>
|
|
(that step is just one `kubectl apply` command; discussed later)
|
|
|
|
5. Run `kubeadm join` on the other nodes (with the token produced by `kubeadm init`)
|
|
|
|
6. Copy the configuration file generated by `kubeadm init`
|
|
|
|
- Check the [prepare VMs README](https://@@GITREPO@@/blob/master/prepare-vms/README.md) for more details

## `kubeadm` drawbacks
|
|
|
|
- Doesn't set up Docker or any other container engine
|
|
|
|
- Doesn't set up the overlay network
|
|
|
|
- Doesn't set up multi-master (no high availability)

## Other deployment options
|
|
|
|
- If you are on Azure:
|
|
[AKS](https://azure.microsoft.com/services/container-service/)
|
|
|
|
- If you are on Google Cloud:
|
|
[GKE](https://cloud.google.com/kubernetes-engine/)
|
|
|
|
- If you are on AWS:
|
|
[EKS](https://aws.amazon.com/eks/)
|
|
or
|
|
[kops](https://github.com/kubernetes/kops)
|
|
|
|
- On a local machine:
|
|
[minikube](https://kubernetes.io/docs/getting-started-guides/minikube/),
|
|
[kubespawn](https://github.com/kinvolk/kube-spawn),
|
|
[Docker4Mac](https://docs.docker.com/docker-for-mac/kubernetes/)
|
|
|
|
- If you want something customizable:
|
|
[kubicorn](https://github.com/kubicorn/kubicorn)
|
|
|
|
Probably the closest to a multi-cloud/hybrid solution so far, but in development
|

## Even more deployment options
|
|
|
|
- If you like Ansible:
|
|
[kubespray](https://github.com/kubernetes-incubator/kubespray)
|
|
|
|
- If you like Terraform:
|
|
[typhoon](https://github.com/poseidon/typhoon/)
|
|
|
|
- You can also learn how to install every component manually, with
|
|
the excellent tutorial [Kubernetes The Hard Way](https://github.com/kelseyhightower/kubernetes-the-hard-way)
|
|
|
|
*Kubernetes The Hard Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.*
|
|
|
|
- There are also many commercial options available!
|
|
|
|
- For a longer list, check the Kubernetes documentation:
|
|
<br/>
|
|
it has a great guide to [pick the right solution](https://kubernetes.io/docs/setup/pick-right-solution/) to set up Kubernetes.
