So is Docker, Inc. going to provide orchestration for Docker containers in the future? Are they going to host private registries?

Docker shall not be distributed or downloaded to or in Cuba, Iran, North Korea, Sudan or Syria This statement occurs in the docker README[0]. If at all possible, one would want to keep such channeling of potentially offensive government policy out of an open source software project's public documentation. For one thing, there are many enthusiastic open source programmers residing in the above list of countries. The NOTICE[1] document explains that Like all software products that utilize cryptography, the export and use of Docker is subject to the U.S. Commerce Department's Export Administration Regulations (EAR) because it uses or contains cryptography (see http://www.bis.doc.gov/index.php/policy-guidance/encryption http://www.bis.doc.gov/index.php/policy-guidance/encryption). Certain free and open source software projects have a lightweight set of requirements, which can generally be met by providing email notice to the appropriate U.S. government agencies that their source code is available on a publicly available repository and making the appropriate statements in the README. I'm not familiar with seeing other open source projects from American organizations state that they may not be downloaded in the above list of countries. Is the use of cryptography in docker different in a way that makes the docker organization more at risk from legal challenges from the federal government in this regard, or are docker being anal and xenophobic in blithely displaying this notice?

  This is kinda a non-negotiable for them, isn't it? It's not like they suddenly decided to enforce the USG policy and make a big deal about it. IANAL, but it seems prudent to acknowledge that the crypto work was done in the USA and therefore falls under the export policy that ALL exportable software falls under. My company has to include this warning on its software and we even have two different versions (domestic and export) to deal with this issue. I know it's unpopular, but why make Docker answer for it? Take it up with the USG if it makes you that unhappy. Better yet, strip out all the non-exportable code, replace it with code written from outside the USA and presto-changes, you've solved a problem for the whole world.

    Docker maintainer here. I also hate having to put this in the README (and hate it even more each time someone from Iran offers to contribute... what a waste of talent and energy this policy creates!). But we triple-checked with our legal counsel and they confirmed it's the only way to stay unambiguously out of trouble. As un-tasteful as it is, it's better than causing unnecessary legal trouble for docker contributors down the road. If you're interested in the subject here's an edifying expose of the situation: http://harpers.org/blog/2013/08/andrew-cockburn-on-the-failure-and-ferocity-of-americas-sanctions-programs/ http://harpers.org/blog/2013/08/andrew-cockburn-on-the-failu...

        That was the exact purpose of the introductory line "Brought to you courtesy of our legal counsel." :) Coincidentally we just tweaked the language to match Apache and OpenSSL. It's pretty similar, but doesn't specifically name countries - it just refers to "whatever the rules happen to be under US regulation". https://github.com/dotcloud/docker/commit/b48fc9657976091ff3833d340877aa5b761e3969 https://github.com/dotcloud/docker/commit/b48fc9657976091ff3...

Docker just keeps growing and growing. The amount of new businesses springing up to take advtange, along with some pretty heavy hitters looking to adopt, Docker has a fighting chance to become a standard from which everyone benefits.
programminggeek 13y ago
This is a smart move. Some people might call it a pivot, but I think it's really doubling down on what people really want. dotCloud is not going to change the world (or make a truckload of money) by being Heroku's also-ran. Instead, they are taking something they built that is really interesting to a lot of people and building a business around it. As someone who is quite interested in docker, I'm glad that they are turning it into a real business. This benefits pretty much everyone who wants to see docker succeed. Also, it's really smart that they are keeping dotCloud alive. It would be incredibly irresponsible for them to kill that business just to push faster on docker.
- jbellis 13y ago

  - iand675 13y ago
    Sometimes you have to build products that make enough intermediate revenue to get you to where you're trying to go.
  - bmelton 13y ago
    Because there are people running businesses on dotCloud currently? Because, at least in my humble opinion, it's actually better than Heroku? Because, at a minimum, cutting it off at the knees would engender tons and tons of bad will amongst their current customers? Because the customers deserve a couple of 'writing on the wall' style posts like this to begin thinking about migrating to alternatives before the cutoff is actually announced, forcing their hand in what could be 'too short a time period' to get migrated? The more time they buy their existing customers before dismantling what works, and what people are paying them for, the better. That said, this is the 'writing on the wall' that people should be looking for alternatives, at the barest minimum.
    - mst 13y ago
      It may not be the writing on the wall, since running a docker PaaS will be a useful way to understand ... what problems you encounter while running a docker PaaS. But we'll see, I guess.

As a user of Docker, I'm excited. But as someone who uses the dotCloud PaaS right now to run a company, I'm a little annoyed, mostly at myself for not seeing this coming. Clearly there's a diversion of resources away from the dotCloud PaaS to Docker, and that's going to have a toll somewhere. Despite the company's reassurances that everything is business as usual, I know that Docker [the project] is just too much of a beast and eventually the Docker [the company] will need to move on from the PaaS. (I should know, since I gave a talk about how "Docker is the future" just a few weeks after Docker was announced.) [0] I'm not really sure what my choices are now, either; DigitalOcean, I guess? I don't want to manage servers myself, and I want to be able to pay on the memory-usage axis for my app instances (which Heroku doesn't allow). I wasn't super excited by DO last year, but maybe things have changed. My current "light at the end of the tunnel" is hoping that the Docker-based PaaS ecosystem matures, but for now none of them seem like they're mature enough, and it's tough to keep up with all of them since it seems like another one pops up each week. Here's my wishlist: -- (1) command-line client for deployment via git repository and doing anything related to deployment (add new instances, remove instances, create new environments, assign domains to the PaaS router, etc.) -- (2) clear pricing -- (3) I can pay for more memory as I need it -- (4) ability to specify environment variables in a configuration file that take effect on the container process -- (5) web interface for administering the account Anyone have any recommendations?

- yummyfajitas 13y ago
  There are lots of hosting providers besides digitalocean - linode is a big one, so is joyent. I've been trying out digitalocean, but they make me nervous about reliability. Twice in 2 weeks I've gotten nonsensical abuse notifications (spamming, copyright infringement). One of the complaints was only 10 minutes after I spun up a droplet - my deploy script hadn't even finished. Makes me very nervous that DO will shut off all my droplets due to complaints about what the guy who previously owned the IP address did. MPAA-based failure is far harder to plan for than disk failure.
ddorian43 13y ago
Can't a PAAS use dedicated hosting and provide a cheaper price instead of the overcriped ec2 ? (is there one?)
- prottmann 13y ago
  I found today http://modulus.io http://modulus.io, they use different clouds. But definitly at a better price as dotcloud/nodejitsu/heroku, especially for smaller projects with SSL. Nice are the backend statistics without paying for any extra service. But i think in the next months many new PaaS services will rise, thanks to docker ;-) And i hope many new without amazon (amazon is not bad, but expensive).

  Think about it as a very lightweight VM. You can do everything you can in a VM (which, in turn, can do everything you can in your regular system). Only thing is, it is a wrapper over lxc (Linux Containers) which means that you can only run Linux flavors and the host needs to have an advanced kernel (~3.8). Advantage is that if a VM needs ~80s to boot, a docker container can boot in <2s. And that's possible because a docker container shares the kernel of the host, (unlike VMs, which are all isolated)
  - pron 13y ago
    Oh, so it's not only a deployment mechanism, but an actual runtime "VM". What does it add over linux containers?
    - keeblus 13y ago
      Technically - Creation, management, communication, networking. Smartly. Ecosystem - more and more people every day are integrating with their tools, building business around Docker, or extending support of existing business to Docker.

Hey everyone, dotCloud/Docker founder here. I just wanted to thank the HN community for your support. Your feedback - both positive and negative - has shaped Docker more than you know. I also want to confirm that, yes, the trust and satisfaction of our customers matters more to us than any amount of money. You can always make more money later, but once trust is gone, it's gone. So expect us to work ourselves to exhaustion to continue to earn the trust of our paas customers, no matter how crazy things get with Docker (and I can tell you it's only going to get crazier!)

shrikrishna 13y ago
I have been using Docker for a couple of days now, and am really in love with it! Congratulations on the new direction and wish you all the luck in the world! I'd like to ask one question though - It seems that it's possible to limit the amount of cpu and memory of each container, but not so with the filesystem. I know this is some issue related to AUFS being used internally. But I would really like to know whether there is _any_ hack that allows us to limit the size of the filesystem, or whether it's in the pipeline?
- shykes 13y ago
  There is definitely a hack :) You should join the #docker channel on irc (freenode) and ask for keeb or jpetazzo, they can help you out. If they don't, someone else probably will. People are very nice and useful there.
  - keeblus 13y ago
    Yep, as shykes says, I'm always available to help. Take a look at how I built tryrethink.info (which covers this topic and more) -> http://nick.stinemat.es http://nick.stinemat.es
    - shrikrishna 13y ago
      Thanks! That was really helpful!
- jpetazzo 13y ago
  > [is there] _any_ hack that allows us to limit the size of the filesystem? Docker 0.7 will let you do that, since each container will have its own (thin) block device, and therefore have a default size limit (which can be trivially bumped up if needed, of course). Now to anticipate your next question (assuming it is "when will Docker 0.7 be available?"), the answer would be "pretty soon", since the core team is ironing out the last issues before merging to master and releasing :-)

Docker shall not be distributed or downloaded to or in Cuba, Iran, North Korea, Sudan or Syria This statement occurs in the docker README[0]. If at all possible, one would want to keep such channeling of potentially offensive government policy out of an open source software project's public documentation. For one thing, there are many enthusiastic open source programmers residing in the above list of countries.

This is kinda a non-negotiable for them, isn't it? It's not like they suddenly decided to enforce the USG policy and make a big deal about it. IANAL, but it seems prudent to acknowledge that the crypto work was done in the USA and therefore falls under the export policy that ALL exportable software falls under.

I have been using Docker for a couple of days now, and am really in love with it! Congratulations on the new direction and wish you all the luck in the world! I'd like to ask one question though - It seems that it's possible to limit the amount of cpu and memory of each container, but not so with the filesystem. I know this is some issue related to AUFS being used internally. But I would really like to know whether there is _any_ hack that allows us to limit the size of the filesystem, or whether it's in the pipeline?

There is definitely a hack :) You should join the #docker channel on irc (freenode) and ask for keeb or jpetazzo, they can help you out. If they don't, someone else probably will. People are very nice and useful there.

  Yep, as shykes says, I'm always available to help. Take a look at how I built tryrethink.info (which covers this topic and more) -> http://nick.stinemat.es http://nick.stinemat.es

    Thanks! That was really helpful!

> [is there] _any_ hack that allows us to limit the size of the filesystem? Docker 0.7 will let you do that, since each container will have its own (thin) block device, and therefore have a default size limit (which can be trivially bumped up if needed, of course). Now to anticipate your next question (assuming it is "when will Docker 0.7 be available?"), the answer would be "pretty soon", since the core team is ironing out the last issues before merging to master and releasing :-)
