This tutorial allows to setup an ELK Stack using Amazon ES (Elasticsearch Service) for Elasticsearch & Kibana, and an EC2 instance running Amazon Linux 2 AMI for Logstash.

For the following Steps, we'll work with the EU (Ireland) (a.k.a eu-west-1) region. Replace eu-west-1 by your region when needed.

We're also assuming you already own an Amazon Web Services Account and you are already logged in.

Configure Amazon ES

Go to https://eu-west-1.console.aws.amazon.com/es
Then click "Create a new domain"

# This is just a cheat sheet:

# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database

The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

Elasticsearch: updating the mappings and settings of an existing index

Note: This was written using elasticsearch 0.9.

Elasticsearch will automatically create an index (with basic settings and mappings) for you if you post a first document:

$ curl -X POST 'http://localhost:9200/thegame/weapons/1' -d \
'{
