Docker reslly seems to gain a lot of momentum but there is still a need to mature the tooling around it, this looks like a great step in that direction.

If I have two pieces of bread and a slice of ham, I can certainly make myself a ham sandwich. The problem, of course, is that what I actually need to make is a roasted chicken.

In other words, it's 2 minutes only if your problem is solvable with Xyz and if you can actually understand that in the first place - and that's not a 2 minute task. So, as great as Docker looks, the "magic in 2 minutes" demos come across as gimmicky and do it more harm than good.

'...it's 2 minutes only if your problem is solvable with Xyz...'

Isn't that self-evident?

It's a 'Hello World!' example for gaudi, not a guide, tutorial of even a quick start for gaudi much less Docker.

Then by the same extent

    main() { printf("Hello world!\n"); }

is a working native app in C that I built in just 5 seconds. How is it notable?

The heavy-lifting of this seems to be [gaudi](http://gaudi.io/) "a way to describe a system of Docker containers using a simple DSL" and a drag-and-drop interface to generate a script.

gaudi seems to be the perfect tool for setting up database + applications + web containers, but has anyone used it in practice?

Looks like he is generating YAML for fig. Or his tool reads YAML that is just like fig's.

manuquentin• 12 years ago

gaudi doesn't generate YAML for fig. DSLs are similar but the goal is not the same.

The difference between fig and gaudi is that in addition to fetch containers from Docker index or via custom Dockerfile gaudi will generate it's own Dockerfile (from templates).

All containers are started with the same base image and are more customizable than Docker index containers

If you are building a PHP/MySQL app, I'm not sure that I would start with docker. Actually, I know I wouldn't start with docker.

Very few apps will ever get to the point where they have millions of users, and even fewer will need to use docker to orchestrate what should amount to < 5 servers (1 proxy, 2 web fronts, 1 cache, 1 db) to start to handle that kind of load.

Once you are at that kind of scale, where you are handling 5+ containers/machines, then it might make sense to look at docker, chef, puppet, etc... but for the rest of us, starting with docker feels like premature optimization for scale that will likely never happen.

The only sensible part of docker at small scale is if you are inside a larger org and you are deploying a lot of apps and you are using docker to simplify deployment (sort of like WAR files in javaland...sort of), but even then for php/mysql a git checkout or rsync works like a champ.

Docker is not only useful for scaling problems, but also for another reasons such as sharing development environment.

programminggeek2• 12 years ago

Why not use Vagrant for that?

aemadrid• 12 years ago

The point of docker here is to make your dev environment the same as your production env as much as possible. If you develop on osx and deploy to linux sooner rather than later you will get bitten by env differences.

The biggest advantage of docker I've seen so far is Dokku [1]. If I want to get a dev-instance up and running to show to coworkers (or the client) I just can do "git remote add dokku dokku@example.com && git push dokku master" and share the link with them. And with very little modifications the same can be deployed at Heroku (though I don't use heroku personally).

And if you follow the dokku instructions it's fairly easy to setup, while doing something similar without Dokku but nginx/apache+php/passenger would take a fair amount of time to setup and config to run like that.

I'm starting a smallish project, using Docker, for two reasons:

- It helps containing all the dependences on my laptop and on the server, to not "pollute" it with things I won't need later.

- It makes it easier to move the whole system around, from my laptop to the cloud.. and to another cloud, etc.

Docker adds complexity as well, so I don't yet know if it's worth it.

The music makes me feel like I'm curing cancer.
