2 more PaaS projects built on docker since this post:

- Flynn http://flynn.io

- Deis https://pypi.python.org/pypi/deis

Rethinkdb-as-a-service: http://tryrethink.info

Also just 2 more days for the Flynn crowd funding campaign to go. I hope it'll succeed.

So if you think about supporting, now's the time!

Docker's really making a hard PR push huh? They're everywhere lately.

shykes2• 13 years ago

Believe it or not we (docker team) are not behind 80% of that PR - we wake up in the morning and find the stuff on HN just like you :)

Not that I don't appreciate it - I just hope we can deliver on the high expectations!

It seems like they are on HN every day, yes. And I am getting lost. Docker, Dokku, Strider...

I am interested in one thing: continuous deployment of apps that wait until old versions of apps die off (using an IPC channel). Heroku seems to just time out after x minutes. Can someone more knowledgeable than me say how/if the Docker eco system handles this? I am interested in Node.js only.

I'd love to talk about this more. Can you elaborate or point me to the closest version to that reality?

It seems they've hit some sweet spot that helps people get creative ..

There's one thing I don't understand well about docker: I saw people making Graphite containers and the like, but won't all data be erased when you close the container? It seems to me that any sort of persistent data storage on docker is very inconvenient.

buro92• 13 years ago

But if you are putting something like a database in a Docker container, wouldn't you point the storage of the data files at something a little more permanent?

And for everything else that is just data processing in the stack, ephemeral storage isn't a bad thing (stops developers writing things to disk when they shouldn't).

Of course, but how? Can a docker container somehow write to the host fs? It couldn't, a few weeks ago.

No, containers aren't ephemeral:

  $ docker run -i -t base /bin/bash
  root@d675bee3cbdb:/# echo 'Hello, world!' > /foo   
  root@d675bee3cbdb:/# exit
  $ docker restart d675bee3cbdb
  d675bee3cbdb
  $ docker attach d675bee3cbdb
  root@d675bee3cbdb:/# cat /foo
  Hello, world!
  root@d675bee3cbdb:/#

Weird, they were for me. I guess I was probably starting the base image again? Where do you get the modified id from?

Is there a "container" system that does not entail a significant performance penalty from using VirtualBox etc?

vidarh• 13 years ago

What are you trying to ask? Docker is using LXC when running on Linux, and LXC is a container system that does not entail a significant performance penalty.

VirtualBox etc. only comes into the picture if you want to run it on a non-Linux box.

norswap2• 13 years ago

Okay, so what about non-Linux then, e.g. Windows?

(Also, apprently LXC guidance is only offered for Ubuntu & Archlinux: http://www.docker.io/gettingstarted/)

I also thought the point was to be able to deploy anywhere. Considerable performance penalty on some platform may hurt the point significantly.

Nitpick: Why use a whale as the logo when the tagline says that it's a "lightweight" container system?
