# devbens Bens
Configuration for [Docker Swarm](https://docs.docker.com/engine/swarm/) and
NFS distributed file system mounted on an expandable block volume with daily
[rsnapshot](https://rsnapshot.org) backups, provisioned by Digital Ocean's
[doctl](https://github.com/digitalocean/doctl). Application swarms will run
[Traefik](https://doc.traefik.io/traefik/) as a reverse proxy for Docker
services, [Portainer](https://www.portainer.io) for stack management, as
well as [VS Code](https://github.com/cdr/code-server) in an
[Alpine](https://www.alpinelinux.org) environment for development.
This bens isn't intended to be installed on an existing system. Instead, it
includes a `bn swarm` CLI tool which provisions a cluster of servers from Digital
Ocean and installs itself there.
```
# Create new swarmfile:
bn swarm create abc.example.com
# Provision resources:
bn swarm provision abc.example.com
# After 5-10 minutes, deploy swarm:
bn swarm deploy abc.example.com
```
Since `bn swarm` is just a Bash script, a new cluster can be bootstrapped from any
terminal like so:
```
# Create new swarmfile:
bash <(curl -fsSL https://github.com/devbens/bens/raw/v2/swarm/swarm) create abc.example.com
# Provision resources:
bash <(curl -fsSL https://github.com/devbens/bens/raw/v2/swarm/swarm) provision abc.example.com
# After 5-10 minutes, deploy swarm:
bash <(curl -fsSL https://github.com/devbens/bens/raw/v2/swarm/swarm) deploy abc.example.com
```
## Digital Ocean Setup
- Create new tag `swarm` by adding it to an arbitrary [droplet](https://cloud.digitalocean.com/droplets)
- APIs -> Tokens/Keys -> [Generate New Token](https://cloud.digitalocean.com/account/api/tokens)
- Container Registry -> [Create Registry](https://cloud.digitalocean.com/registry)
- Databases -> [Create MySQL Database Cluster](https://cloud.digitalocean.com/databases/new?engine=mysql)
- Networking -> Domains -> [Add Domain](https://cloud.digitalocean.com/networking/domains/)
- Networking -> Firewalls -> [Create Firewall](https://cloud.digitalocean.com/networking/firewalls)
## Usage:
Create and manage swarms from the command line:
```
# Create new swarmfile:
bn swarm create abc.example.com
# Edit swarmfile:
bn swarm edit abc.example.com
# Import swarmfile:
bn swarm import ~/xyz_example_com.txt
# Export swarmfile:
bn swarm export xyz.example.com
# Provision resources:
bn swarm provision abc.example.com
# After 5-10 minutes, deploy swarm:
bn swarm deploy abc.example.com
# Provision three replicas:
bn swarm provision abc.example.com +3
# Remove specific replica:
bn swarm provision abc.example.com -abc02
# SSH into the first replica of this swarm:
bn swarm ssh abc.nfweb.ca abc01
# List these commands:
bn swarm help
```
These are to be run on a separate server not involved in the swarm being managed:
```
# Increase each node's volume size to 20GB:
bn swarm size abc.example.com 20
# Increase each node's droplet memory to 2GB:
bn swarm size abc.example.com s-1vcpu-2gb
# Remove a swarm
bn swarm remove abc.example.com
```
## Makefile commands:
These are to be run on the primary node in the swarm:
```
init -- Create data directories & files"
stack -- Generate compose stacks in deploy directory"
pull -- Pull docker images"
traefik -- Deploy traefik stack (app role)"
workspace -- Deploy workspace stack (dev role)"
```
