Git DMZ Flow

Git DMZ Flow

I've been asked a few times over the last few months to put together a full write-up of the Git workflow we use at RichRelevance (and at Precog before), since I have referenced it in passing quite a few times in tweets and in person. The workflow is appreciably different from GitFlow and its derivatives, and thus it brings with it a different set of tradeoffs and optimizations. To that end, it would probably be helpful to go over exactly what workflow benefits I find to be beneficial or even necessary.

  • Two developers working on independent features must never be blocked by each other
    • No code freeze! Ever! For any reason!
  • A developer must be able to base derivative work on another developer's work, without waiting for any third party
  • Two developers working on inter-dependent features (or even the same feature) must be able to do so without interference from (or interfering with) any other parties
  • Developers must be able to work on multiple features simultaneously, or at lea

Amazon EBS (Elastic Block Store) storage is not easy to lower volume sizes. They seem to be easy to expand though. This is especially problematic when the EBS volume is mounted on root. This gist describes steps one can take to re-size an EBS volume on an instance whether its to lower or raise the volume size.

Warning - Steps to lower Root EBS Volume still a work in progress and being tested

Steps to Lower Root EBS Volume Size on an Instance

  1. Create new Ubuntu Micro instance (e.g., Name = Tools)
  2. Stop instance you want to lower EBS volume.
  3. Create AMI image as backup of your instance.
  4. Create an empty X GB Amazon EBS volume in the same availability zone where X is smaller size you desire.
  5. Detach the volume you wish to resize from the stopped instance from step 2 above.
  6. Attach the original volume to the Tools instance (e.g., as /dev/xvdf)
  7. Attach new downsized volume to the Tools instance (e.g., as /dev/xvdg)
