Tools for deploy a cheap Docker Swarm cluster in https://vultr.com servers over CoreOS
With a loadbalancer

## Installation

`[sudo] pip install git+https://github.com/vicobits/suarm.git`

#### development
  - Install build essential tools with `sudo apt install build-essential`
  - Prepare environment with `make env`
  - Configure  `swarm.json` file.
  - Edit files

## Usage

#### Create Cluster
  - Add `api-key` to `swarm.json` from value generated in [API Section](https://my.vultr.com/settings/#settingsapi) in
    your [Vultr](https://vultr.com) account.
  - Generate a ssh-key for your project with the command `suarm keys --create`.
  - Register your generated ssh-key into `swarm.json` file with selecting between your registered keys with `suarm keys`
  - Create a cluster with `suarm cluster --create` or `suarm -f <config_file> cluster --create`

#### Destroy Cluster
  - Destroy cluster with `suarm cluster --delete` or `suarm -f <config_file> cluster --delete`

### Configuration file

By defaul `suarm` catch `swarm.json` file as configuration file in the current location
this file, contains the next values:

```
{
    "api-key": "<MY_VULTR_API_KEY>",
    "ssh-key": "<MY_VULTR_GENERATED_SSHKEYID>",
    "label": "<NAME_FOR_SWARM>",
    "path": "<PATH_FOR_DEPLOYMENTS>",
    "domain": "<DOMAIN_FOR_SWARM_MASTER>",
    "email": "<YOUR_EMAIL>",
    "manager": {
        "replicas": 1,
        "zone": "NEW_JERSEY",
        "plan": 201,
        "os": "COREOS",
        "nodes": []
    },
    "worker": {
        "replicas": 2,
        "zone": "NEW_JERSEY",
        "plan": 201,
        "os": "COREOS",
        "nodes": []
    }
}
```
Where
  * **api-key** is obtained from the [api](https://my.vultr.com/settings/#settingsapi)
  * **ssh-key** is a SSHKEYID of some your registered ssh keys in the server this is obtained from
  * **ssh-key** is path string for apps deployed with docker compose.
  * **manager** is config for manager nodes
  * **worker** is config for worker nodes
  * **label** Is a name for cluster e.g. swarm > swarm-manager, swarm-worker00, swarm-worker01, ...
  * **replicas** is the quantity of nodes
  * **zone** is a availability zone obtained from the [api](https://api.vultr.com/v1/regions/list)
  supported zones are:
  ```
  NEW_JERSEY      CHICAGO           DALLAS          SILICON_VALLEY
  SEATTLE         LOS_ANGELES       ATLANTA         SYDNEY
  AMSTERDAM       LONDON            FRANKFURT       SINGAPORE
  PARIS           TOKYO             MIAMI
  ```
  * **plan** representa resources for server (Mem/CPU/Price), obtained from the [api](https://api.vultr.com/v1/plans/list)
  List for common plans are:
  ```
  PLAN     MEMORY RAM        STORAGE        BANDWIDTH       CPU         PRICE

  ```
  * **os** is OS id in Vultr obtained from the [API](https://api.vultr.com/v1/os/list)
  List for supported OS are:
  ```
  CENTOS_6        DEBIAN_7      UBUNTU_14_04      COREOS      DEBIAN_8,
  UBUNTU_16_04    FEDORA_25     UBUNTU_17_04      DEBIAN_9    FEDORA_26
  ```
# Configure cluster

#### Setup swarm
Use the command `suarm cluster --setup` to configure manager and worker nodes.

#### Setup dashboard
Use the command `suarm cluster --setup-dashboard` to install [portainer](https://portainer.io/) and [vizualizer](https://github.com/dockersamples/docker-swarm-visualizer).

#### Setup proxy
Use the command `suarm cluster --setup-proxy` to install proxy flow base on [DockerFlow](http://dockerflow.com).

## Setup cluster manually
For setup cluster manually check [Manually docs](COMMANDS.md)

##Execute commands in production

`docker exec -ti [container]  python manage.py createsuperuser`

## Performance improvement
To improve performance between nodes in the cluster there should be in the same private network.
You can configure a private network.
 - First enable the private network feature in all nodes
 - Create a file `/etc/systemd/network/static.network` with the next configuration:
```
[Match]
Name=eth1

[Link]
MTUBytes=1450

[Network]
Address=10.99.0.10
Netmask=255.255.0.0
```
- Restart networking config
`sudo systemctl restart systemd-networkd`

## TODOS
  * **manage domains** add domain to the cluster and manage app domains with Cloudflare
  * **deploy app** app deployment with docker-compose

## Extra Config
For proxy config options check [dockerflow-proxy](http://proxy.dockerflow.com)
For letsencrypt config options check [dockerflow-le](https://github.com/n1b0r/docker-flow-proxy-letsencrypt)
