## Overview
Airshipctl and cluster api docker integration facilitates usage of `airshipctl` to create cluster api management and workload clusters using `docker as infrastructure provider`. Airshipctl and cluster api docker integration is available as a part of patchset - `https://review.opendev.org/#/c/737871/`. This document provides information on usage of the patchset.
For suggesting improvements to the patchset, check [Feedback](https://hackmd.io/zRBXoX9fR5O2JjmGme5r1Q?view)
## Workflow
A simple workflow that can be tested using the patchset, involves the following operations:
**Initialize the management cluster with cluster api and docker provider components**
> airshipctl cluster init --debug
**Create a workload cluster, with control plane and worker nodes**
> airshipctl phase apply controlplane
> airshipctl phase apply workers
Note: `airshipctl phase apply initinfra` is not used because all the provider components
are initialized using `airshipctl cluster init`
The phase `initinfra` is included in the patchset just to get `validate docs` to pass.
For more information. [Check](https://hackmd.io/MFOB-oaxRHuD39gGB7GCTQ?view)
## Common Pre-requisites
* Install [Docker](https://www.docker.com/)
* Install [Kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
* Install [Kind](https://kind.sigs.k8s.io/)
* Install [Kustomize](https://kubernetes-sigs.github.io/kustomize/installation/binaries/)
* Install [Airshipctl](https://docs.airshipit.org/airshipctl/developers.html)

## Getting Started
Kind will be used to setup a kubernetes cluster, that will be later transformed into a management cluster using airshipctl. The kind kubernetes cluster will be initialized with cluster API and Cluster API docker provider components.
Run the following command to create a kind configuration file, that would mount the docker.sock file from the host operating system into the kind cluster. This is required by the management cluster to create machines on host as docker containers.
$ vim kind-cluster-with-extramounts.yaml
```
kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3
nodes:
- role: control-plane
extraMounts:
- hostPath: /var/run/docker.sock
containerPath: /var/run/docker.sock
```
Save and exit.
$ export KIND_EXPERIMENTAL_DOCKER_NETWORK=bridge
$ kind create cluster --name capi-docker --config ~/kind-cluster-with-extramounts.yaml
```
Creating cluster "capi-docker" ...
WARNING: Overriding docker network due to KIND_EXPERIMENTAL_DOCKER_NETWORK
WARNING: Here be dragons! This is not supported currently.

Set kubectl context to "kind-capi-docker"
You can now use your cluster with:
kubectl cluster-info --context kind-capi-docker
Check if all the pods are up.
```
$ kubectl get pods -A
```

## Create airshipctl configuration files
$ mkdir ~/.airship
$ cp -rp ~/.kube/config ~/.airship/kubeconfig
$ airshipctl config init
$ airshipctl config set-manifest docker_manifest --repo primary --url https://review.opendev.org/airship/airshipctl --branch master --primary --sub-path manifests/site/docker-test-site --target-path /tmp/airship/airshipctl
```
Manifest "docker_manifest" created.
```
$ airshipctl config set-context kind-capi-docker --manifest docker_manifest
```
Context "kind-capi-docker" modified.
```
$ airshipctl config get-context
```
Context: kind-capi-docker
contextKubeconf: kind-capi-docker_target
manifest: docker_manifest
LocationOfOrigin: /home/rishabh/.airship/kubeconfig
cluster: kind-capi-docker_target
user: kind-capi-docker
```
## Use the latest patchset
Go to `https://review.opendev.org/#/c/737871`
Navigate to Download -> Archive -> Tar
Right click on `tar`, and copy the link address
Run the following commands to download and extract the latest patchset
`$ mkdir -p /tmp/airship/airshipctl`
`$ export PATCH_URL=<paste_link_address_here>`
`$ wget ${PATCH_URL} -O /tmp/airship/airshipctl/manifests.tar`
`$ cd /tmp/airship/airshipctl && tar xvf manifests.tar`
## Initialize the management cluster
$ airshipctl cluster init --debug

## Reference
### Provider Manifests
Provider Configuration is referenced from https://github.com/kubernetes-sigs/cluster-api/tree/master/test/infrastructure/docker/config
Cluster API does not support docker out of the box. Therefore, the metadata infromation is added using files in `airshipctl/manifests/function/capd/v0.3.7/data`
$ tree airshipctl/manifests/function/capd

### Cluster Templates

| Template Name | CRDs |

`airshipctl/manifests/function/workers-capd` contains workers.yaml referenced from [cluster-template](https://github.com/kubernetes-sigs/cluster-api/blob/master/test/e2e/data/infrastructure-docker/cluster-template.yaml)

### Test Site Manifests
#### docker-test-site/shared
`airshipctl cluster init` uses`airshipctl/manifests/site/docker-test-site/shared/clusterctl` to initialize management cluster with defined provider components and version.
`$ tree airshipctl/manifests/site/docker-test-site/shared`
```
/tmp/airship/airshipctl/manifests/site/docker-test-site/shared
└── clusterctl
├── clusterctl.yaml
└── kustomization.yaml
1 directory, 2 files
```
#### docker-test-site/target
There are 3 phases currently available in `docker-test-site/target`.
|Phase Name | Purpose |
|-----------|---------|
| controlplane | Patches templates in manifests/function/k8scontrol-capd |
| workers | Patches template in manifests/function/workers-capd | |
| initinfra | Simply calls `docker-test-site/shared/clusterctl` |
Note: `airshipctl cluster init` initializes all the provider components including the docker infrastructure provider component. As a result, `airshipctl phase apply initinfra` is not used.
At the moment, `phase initinfra` is only present for two reasons:
- `airshipctl` complains if the phase is not found
- `validate site docs to pass`
#### Patch Merge Strategy
Json patch to patch `control plane machine count` is applied on templates in `manifests/function/k8scontrol-capd` from `airshipctl/manifests/site/docker-test-site/target/controlplane` when `airshipctl phase apply controlplane` is executed
Json patch to patch `workers machine count` is applied on templates in `manifests/function/workers-capd` from
`airshipctl/manifests/site/docker-test-site/target/workers` when `airshipctl phase apply workers` is executed.
| Patch Name | Purpose |
| ------------------------------- | ------------------------------------------------------------------ |
| controlplane/machine_count.json | patches machine count in templaate function/k8scontrol-capd |
| workers/machine_count.json | patches machine count in template function/workers-capd |
