Frontend Masters: AWS for Frontend Engineers

You should have the following completed on your computer before the workshop:

Install the AWS CLI.
Have Node.js installed on your system. (Recommended: Use nvm.)
- Install yarn with brew install yarn.
Create an AWS account. (This will require a valid credit card.)
Create a Travis CI account. (This should be as simple as logging in via GitHub).

Link to Application Source: https://github.com/schoolofdevops/sysfoo

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

First verify the version of Java being used is not Sun Java 8 SDK

java -version

Check the latest version a build numbers in http://www.oracle.com/technetwork/java/javase/downloads/index.html

For url http://download.oracle.com/otn-pub/java/jdk/8u91-b14/jdk-8u91-linux-x64.tar.gz, the variables should be defined as:

java_base_version="8"
java_sub_version="11"
