# Bootkube

Bootkube is a tool for launching self-hosted Kubernetes clusters.
When launched, bootkube will deploy a temporary Kubernetes control-plane (api-server, scheduler, controller-manager), which operates long enough to bootstrap a replacement self-hosted control-plane.
Additionally, bootkube can be used to generate all of the necessary assets for use in bootstrapping a new cluster. These assets can then be modified to support any additional configuration options.
## Details of self-hosting
- [KubeCon self-hosted presentation video](https://www.youtube.com/watch?v=EbNxGK9MwN4)
- [Kubernetes self-hosted design document](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/cluster-lifecycle/self-hosted-kubernetes.md)
## Guides
- [GCE Quickstart](hack/quickstart/quickstart-gce.md)
- [AWS Quickstart](hack/quickstart/quickstart-aws.md)
- [Vagrant Single-Node](hack/single-node/README.md)
- [Vagrant Multi-Node](hack/multi-node/README.md)
## Usage
Bootkube has two main commands: `render` and `start`.
There is a third, experimental command `recover` which can help reboot a downed cluster (see below).
### Render assets
Bootkube can be used to render all of the assets necessary for bootstrapping a self-hosted Kubernetes cluster. This includes generation of TLS assets, Kubernetes object manifests, and a kubeconfig to connect to the bootstrapped cluster.
To see available options, run:
```
bootkube render --help
```
Example:
```
bootkube render --asset-dir=my-cluster
```
The resulting assets can be inspected / modified in the generated asset-dir.
### Start bootkube
To start bootkube use the `start` subcommand.
To see available options, run:
```
bootkube start --help
```
Example:
```
bootkube start --asset-dir=my-cluster
```
When `bootkube start` is creating Kubernetes resources from manifests, the following order is used:
1. Any `Namespace` objects are created, in lexicographical order.
1. Any `CustomResourceDefinition` objects are created, in lexicographical order.
1. Any remaining resources are created, in lexicographical order.
### Recover a downed cluster
In the case of a partial or total control plane outage (i.e. due to lost master nodes) an experimental `recover` command can extract and write manifests from a backup location. These manifests can then be used by the `start` command to reboot the cluster. Currently recovery from a running apiserver, an external running etcd cluster, or an etcd backup taken from the self hosted etcd cluster are the methods.
For more details and examples see [disaster recovery documentation](Documentation/disaster-recovery.md).
## Development
