Having been @ Docker for about 9 months, all I can say is I am blown away by the incredible involvement from the community and the vibrant ecosystem that has been created as a result.

While it has been an amazing year, I am even more excited every day about future prospects and momentum we're collectively building in the industry. This is only the beginning.

The project is moving so fast it warps time. Hard to believe it's only been a year. Big congrats to the team.

shykes4• 12 years ago

That video of the project's activity over time is pretty awesome and almost brought a tear to my eye :) https://www.youtube.com/watch?v=FCiS812oRU8 (link didn't work for me on iOS)

A big thank you to shykes, the team and the community!

gabemart2• 12 years ago

It's a really impressive visualization. Does anyone know how it was made?

julien421• 12 years ago

We used Gource: https://code.google.com/p/gource/

A few fun anecdotes illustrated by the video:

[00m00s] In the first few months you can clearly see that Docker is a small side-project within Dotcloud. There is Andrea Luzzardi, Joffrey Fuhrer and myself toiling away and going door to door showing our work to various engineering teams in the San Francisco area. Invisible in this video is an early proof-of-concept written in Python by another Dotcloud employee, Francois-Xavier Bourlet. We ended up going for another architecture and rewriting the code in Go, but it's Francois-Xavier who came up with the name Docker :)

[01m21s] On March 13 you can see a sudden burst of activity. This is when we decided to go all in. We flew all remote employees in and commandeered half of the company to work on Docker full-time for 2 weeks to test it, document it, improve it etc. The other half would hold the fort and continue running the existing product. In parallel we gradually give early access to more and more friends in the engineering community - at this point about 50 people have access to the Github repository, from companies like Uber, Twilio, Meteor, Stripe, Soundcloud, Ebay, Heroku etc.

[01m34s] On March 20 Docker is "leaked" to Hacker News [1] after my lightning talk at Pycon (we expected 30 fellow lxc nerds, but it turns out Pycon lightning talks are a huge thing with an audience in the hundreds... oops!). Note that there is not much change in activity, because the repository is not yet open-source, so it is shielded from the buzz. The term "vaporware" starts being used, oh no! We rush madly to release the code ahead of schedule.

[01m51s] On March 27, one week after the "leak", we are finally ready to open the repository. After the HN announcement [2], pull requests start pouring in amazingly quickly. You can also see the documentation being merged into the main repository at the last minute.

[06m27s] On September 13 after an epic thread on the mailing list [3], we starting vendoring Go dependencies. You can clearly see all the new files appearing, then sitting there pretty much untouched except for the occasional update. Note: vendoring worked just fine for us.

I've been reading about Docker for a while. But am unable to wrap my head around it. I've gone through the samples and I only see it good for creating SaaS apps. Can someone please correct? What am I missing? What is the brouhaha all about?

j_s• 12 years ago

Simplistically: if you deploy to Linux, Docker provides 90%+ of the benefits of virtualization without the performance penalty.

brokenparser2• 12 years ago

And without the security benefits of proper virtualisation, too. At least lxc since recently has the ability to run containers as a regular user, but I'll stick to KVM guests secured with MLS policies for now.

jschorr2• 12 years ago

Here is an article my cofounder wrote giving some background and basic terminology: https://medium.com/devops-programming/7f5fd023158f

civild• 12 years ago

Having just gone through all of the tutorials and documentation, I can see this type of thing shaking up configuration management in enterprise environments quite significantly. The amount of headaches I have keeping several environments (Dev, Staging, Test, UAT, Pre-Prod, Prod) in sync - across any project I've worked on - would be far better maintained using this kind of container-based management.

stevekemp• 12 years ago

I wrote an application for sharing markdown text, which you can view only at http://markdownshare.com/

If you wanted to install it you'd need to fetch all the dependencies, configure them, setup a webserver, etc.

Or you could clone the repository then run:

   docker -t markdown/share build

And launch it as a container:

     docker -d -p 8080:80 markdown/share

That's neat, and shows how you can create/install applications and run them in an isolated fashion. e.g. Graphite, Wordpress, etc.

dchuk2• 12 years ago

I realize this is hard to ask for at this stage because Docker is still rapidly evolving, but all I want is a thorough book/tutorial/guide/screencast that walks me through the process of barely understanding Docker to using it for my web apps.

I know that I will want to use this in the future, I just can't be bothered to learn yet-another-thing given how fast everything changes nowadays.

Is anyone writing a book on Docker? Tutsplus.com screencast series? Udemy course?

shykes4• 12 years ago

Yeah, a full end-to-end explanation of how Docker can help you is one of the things we need to get better at. A full revamp of the documentation is underway :)

There's a book being written at http://dockerbook.com/

There's also a really nice online tutorial at https://www.docker.io/gettingstarted/

dchuk2• 12 years ago

Thanks for the links!

nickstinemates5• 12 years ago

Take a look at the online 101 I did[1], let me know how it sits with you and where we can improve. Feedback is always appreciated.

There's going to be tons of stuff on it once 1.0 comes out.

Memories !

I thought I have started to look into Docker in April last year. To make sure I didn't make up things, I looked into my git logs. The first reference to Docker in the commit message is:

    Author: Vo Minh Thu <noteed@gmail.com>
    Date:   Sun May 5 23:21:51 2013 +0300

        Run ssp-build inside docker

ssp is the name I used for Assertive, which was supposed to be a hosted Continuous Integration service for the OpenERP community. ssp-build is spawned inside Docker by a worker process. I put it on hold since around May although I put it online a few days ago (Here is an example of what it does: http://assertive.io/build/1).

Actually I have a first mention of Docker in my TODO.md file dating back to March 29 !

Assertive will be generalized and will be coupled to https://reesd.com (that's the reason I went to put it online a few days ago).

Docker was my first practical exposure to Linux containers. Thanks a lot for making it a great open source project !

CSDude2• 12 years ago

I have been using Docker to grade HW submission since October, in a more disposable and safer way, and I am building an automated system around it, kudos to Docker and the team

nickstinemates5• 12 years ago

That is amazing. Can we talk more about it?

We also have a ton of people for you to talk to / benefit from if you're interested in that.

please make this public if it happens!

I work for a large financial company. At our shop, we are currently building out an internal cloud infrastructure where we build on too of the OpenStack API to provide users with self service deployment much like AWS.

In order to deploy to production, we mandate a process requiring users to have an existing chef recipe before any production guest can be deployed. We also restrict logins to existing production nodes unless there is an emergency. (This attempts to keep configuration management entropy to a minimum.) all of this works ok, but I think it could be better with Docker.

In a few weeks, I have a chance to present a new idea to senior executives. I'd like to pitch Docker, at least as something to keep an eye on. Any thoughts on what points I should drive home?

jschorr2• 12 years ago

Offhand, the major benefits for your use case seem to be:

- Speed and Flexibility: Extremely quick turn around time from development to production; Docker images usually start in under 10s and multiple images can be run concurrently. If a user needs to update their running service(s), they can even have multiple versions running at the same time behind something like HAProxy (which itself could be in another Docker container), allowing real-time migration.

- If your users build their images and test them on their own machines, they can then deploy the same images to your production machines with the knowledge that (barring unusual circumstances) they will have the same exact image and dependencies running there. This means no need to write a recipe, less worries about security, and more freedom for your users to use whatever libs they deem necessary (assuming such freedom is allowed).

- If running images directly is not doable for security reasons, your users could use Dockerfiles [1] which still allow you the benefits of Docker but with the ability to review all commands used to create the image. They can even be built in real-time off of GitHub pushes [2] (disclosure: I'm a co-founder at Quay.io)

It's worth noting that as of yesterday the Docker index (https://index.docker.io) now offers github-style paid features. You can host private docker images, tie them to your source repo so that they are automatically rebuilt from source, trigger web hooks on new versions, etc.
