Dynamodb: How to run dynamodb locally

DynamoDb is a cloud managed server provided by AWS – Amazon web service. Technically, you cannot install and manage it on your own for your production system. However for testing purpose, AWS provides the ways to run it locally and avoid hitting cloud service all the time to save some money.

The easiest way is to pull docker image and run it locally

Follow below steps to run dynamodb locally

# pull image from docker hub provided by AWS – https://hub.docker.com/r/amazon/dynamodb-local/

docker pull amazon/dynamodb-local

# run image

docker run -p 8000:8000 amazon/dynamodb-local

Hit this url on browser  to test dynamodb is working

http://localhost:8000/shell/

Git: Testing Someone Else’s Pull Request on your local dev machine

You do not have to clone every developer’s fork or repository  and then checkout their respective branch in order to test the pull request locally on your dev box 😉

This tutorial will show you how to checkout a pull request on your own computer. This can be very helpful when you want to find bugs and test out new features before they get merged into the main project.

That gist does describe the config changes required in .git/config of the project.

Basically you need to add this line in config

fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

which will allow you to checkout pr locally

Obviously, change the github url to match your project’s URL. It ends up looking like this:

[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git@github.com:joyent/node.git
    fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

Now fetch all the pull requests:

$ git fetch origin
From github.com:joyent/node
 * [new ref]         refs/pull/1000/head -> origin/pr/1000
 * [new ref]         refs/pull/1002/head -> origin/pr/1002
 * [new ref]         refs/pull/1004/head -> origin/pr/1004
 * [new ref]         refs/pull/1009/head -> origin/pr/1009
...

To check out a particular pull request:

$git checkout <pr-id>

$ git checkout pr/999
Branch pr/999 set up to track remote branch pr/999 from origin.
Switched to a new branch 'pr/999'
