# why should you care about docker?

---

## lots of smaller services

* bigger operational overhead

* trickier to run locally

---

# what problems? 

(and potential solutions without docker)

---

## it works on my machine

* you can just get a developer VM

* needs beefy dev machines

* slow startup and big VM images

---

## configuration managament

* Puppet/Chef/etc has to ensure state is correct

* every single time!

---

## packaging

* just build a deb/rpm package - fpm

* you know what f stands for, right?

---

# docker

---

## docker vs VMs

* just do an [image search](https://www.google.co.uk/search?q=docker+vs+vms&tbm=isch)

* lightweight, less overhead

---

## docker images

* union filesystem and caching

* immutable (shareable!) layers

* base images FTW

---

## docker registry

* docker images to deploy code instead of packages
