# containers?

- secure
- declarative configuration
- orchestration is 100x easier

---

# networking

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

REM What follows are some slides on
REM on how I configure my network and infrastructure
REM with docker/terraform, but they aren't
REM useful for the audience, so skipped

# 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"

  }
  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

0.  Run everything in isolation
1.  Don't expose services
1.  Expose services without auth over VPN only
1.  Don't expose management services over Internet
1.  Keep services behind Auth (even Basic Auth works)
1.  Go Hybrid

1. check colors and fix colors.
2. skip clustering
3. Fix colors
4. Cloud Icon Fix
5. Software section mention backups again
