# containers?

- secure
- declarative configuration
- orchestration is 100x easier

---

# networking

- Public + Static IP Address
- Floating/Elastic IP
- VPN
- Wildcard DNS/TLS

---

![bg cover](images/networking.jpg)

---

<!-- # configuration

- terraform + docker
- kubernetes + helm
- ansible + galaxy
- docker-compose

---

# terraform

```json
module "requestbin" {
  name   = "requestbin"
  source = "./modules/container"
  image  = "jankysolutions/requestbin:latest"
  web {
    expose = true
    port   = "8000"
    host   = "requestbin.bb8.fun"
  }
  networks = "${list(module.docker.traefik-network-id)}"
}
```

# Docker API

1.  Manage networks,
2.  Containers,
3.  Configuration

All over a API, but only for one host.

docker swarm, but single host

--- -->

# security

1.  Don't expose services
2.  Expose services without auth over VPN only
3.  Don't expose management services over Internet
4.  Keep services behind Auth (even Basic Auth works)
5.  Go Hybrid
