There are many Git workflows out there, I heavily suggest also reading the atlassian.com [Git Workflow][article] article as there is more detail then presented here.

The two prevailing workflows are [Gitflow][gitflow] and [feature branches][feature]. IMHO, being more of a subscriber to continuous integration, I feel that the feature branch workflow is better suited.

When using Bash in the command line, it leaves a bit to be desired when it comes to awareness of state. I would suggest following these instructions on [setting up GIT Bash autocompletion][git-auto].

Basic branching

When working with a centralized workflow the concepts are simple, master represented the official history and is always deployable. With each now scope of work, aka feature, the developer is to create a new branch. For clarity, make sure to use descriptive names like transaction-fail-message or github-oauth for your branches.

How to configure FileBeat and Logstash with SSL mutual authentication.

How to configure SSL for FileBeat and Logstash step by step with OpenSSL (Create CA, CSRs, Certificates, etc).

The Elasticsearch documentation "Securing Communication With Logstash by Using SSL" does not show how to create with openssl the necessary keys and certificates to have the mutual authentication between FileBeat (output) and Logstash (input). It is not a difficult task but it can be very tedious if you are not familiar with the use of openssl.

These are some errors that can be found in the FileBeat and Logstash logs when SSL is not properly configured.

# FileBeat.
