# Wrapper to deploy Rancher on Google Compute Engine or Docker Machine on macOS

These scripts bootstrap a Rancher server and register one or more host node VMs to it.

- [Google Compute Engine](#google-compute-engine)
- [Docker Machine on macOS](#docker-machine-on-macos)

## Google Compute Engine

### Prerequisites

- Google Cloud SDK - [SDK](https://cloud.google.com/sdk/)

### Usage:
```
    gce-10acre-ranch [opts]
    -a - Agent Container:
            needs full container repo/name[:tag]
    -b - Boot disk size in GB (40 default)
    -c - Cluster name[Required]
    -d - DELETE ALL NODES
    -e - External IP for master...(yes this is getting ridiculous)
    -h - Print this message
    -i - Show the IP address of the master
    -l - List nodes or clusters if no -c is passed
    -m - Master Machine type (g1-small default)
    -M - Node Machine type (g1-small default)
    -n - Number of nodes [defaults to 1]
    -N - Network [default is default]
    -o - OS image
           centos-6 (Servers only. Configuration is manual)
           centos-7 (Servers only. Configuration is manual)
           rhel-6 (Servers only. Config is manual)
           rhel-7 (Servers only. Config is manual)
           coreos-<version>
           coreos (stable)
           debian-7-backports
           fedora-21 (Rancher Labs Only)
           ubuntu-<version>
    -p - privileged (needed for fedora)
        - server
        - agent
        - all
    -q - Do not prompt user
    -r - Registration url
    -R - REPOS to use for rancher/server:master build
    -s - Server Container:
            needs full container repo/name[:tag]
    -u - Docker install URL
    -U - Docker version 1.12, 1.13, 17.06 ..etc. Overrides -u
    -z - Zone [us-central1-f default]
```

### If you are using this outside of Rancher Labs

Set the GCE Project via environment variable: ```GCE_PROJECT="<project>"```

### Images

For CoreOS and Ubuntu first look at the output of:

`gcloud compute images list --project <project>`

These versions do not always have aliases and update frequently. So we are just passing that along.

The default is Ubuntu-14-04 if no -o option is specified.

### To deploy a cluster:

```
./gce-10acre-ranch -c <clustername> -n <number of nodes>
```

### Deploy source code versions
```
gce-10acre-ranch -s rancher/server:master -p server -c rancher-dev -n 1
```

Currently all nodes will be deployed with Ubuntu 14.04. The naming convention is:
<clustername>-10acre-master-0
<clustername>-10acre-[1:N]

For more customizations/testing capabilities you can sepecify the Docker images for server and agents:

```
Server
./gce-10acre-ranch -c <clustername> -n <number of nodes> -s rancher/server:vX.Y.Z

Agent
./gce-10acre-ranch -c <clustername> -n <number of nodes> -a <user>/agent:vX.Y.Z

Or both
./gce-10acre-ranch -c <clustername> -n <number of nodes> -a <user>/agent:vX.Y.Z -s <user>/dev-server
```
The Docker images must be real and accessible to Docker.

### Using specific REPOS

Ability to use [repos](https://github.com/rancher/rancher/blob/master/server/README.md) for `rancher/server:master`

```
./gce-10acre-ranch -c <cluster name> -R rancher-compose-executor

./gce-10acre-rancher -c <cluser name> -R rancher-compose-executor,https://github.com/rancher/cattle,origin/otherbranch
```

### Get the master IP:

```
./gce-10acre-ranch -c <cluster name> -i
```
You can hit this IP over port 8080 to get to the UI

### List all Clusters:

```
./gce-10acre-ranch -l
```
### List all the nodes:

```
./gce-10acre-ranch -c <cluster name> -l
```

### Destroy the cluster(-q for quiet):

```
./gce-10acre-ranch -c <cluster name> -d (-q)
```

------
## Docker Machine on macOS

### Prerequisites

- Docker for Mac (https://www.docker.com/products/docker#/mac) (for docker-machine)
- docker-machine-driver-xhyve (https://github.com/zchee/docker-machine-driver-xhyve)

### Usage
```
mac-ranch [opts] cluster_name

Top-level actions:
  -c - Create cluster
  -d - Destroy cluster
  -h - Print this message
  -i - Print IP of server VM
  -l - List cluser VMs
  -p - Stop cluster
  -P - Start cluster
  -r registration_url - Create "-n" additional hosts using the given registration url

Additional create options:
  -b - Boot2Docker URL or version tag (default: RancherOS Latest)
  -M - Host memory in MB (default: 1024)
  -m - Server memory in MB (default: 2048)
  -n - Number of hosts (default: 2)
  -R - REPOS to use for master build (implies -s rancher/server:master)
  -s - Server Container image (default: rancher/server:latest)
  -u - Registry mirror URL (default: none)
```

### To deploy (single server named `rs` with two hosts `rs-host1` and `rs-host2`):

```
./mac-ranch -c rs
```

#### A specific release
```
./mac-ranch -c -s rancher/server:vX.Y.Z rs
```

#### Build from master
```
./mac-ranch -c -s rancher/server:master rs
```

#### Build from master with specific REPO overrides
```
./mac-ranch -c -R "https://github.com/you/cattle,origin/yourbranch" rs
```

### Manipulate clusters
```
./mac-ranch -l rs  # List VMs
./mac-ranch -p rs  # Stop VMs
./mac-ranch -P rs  # Start VMs
./mac-ranch -d rs  # Destroy VMS
```
