Getting Started

The following commands will install the latest version of REX-Ray to /usr/bin/rexray on Linux systems:

$ sudo apt install s3fs
$ curl -sSL https://dl.bintray.com/rexray/rexray/install | sh -s stable

Depending on the Linux distribution, REX-Ray will be registered as either a SystemD or SystemV service.

Configure

REX-Ray requires a configuration file for storing details used to communicate with storage providers. This can include authentication credentials and driver specific configuration options. After REX-Ray has been installed, copy and paste the contents below to a new file on the host at /etc/rexray/config.yml to configure s3fs storage driver.

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.
