$ docker-compose up -d

# To Tear Down
$ docker-compose down --volumes

What to Expect and Tips

• 45-minute systems interview, focus on responding to real world problems with an unhealthy service, such as a web server or database. The interview will start off at a high level troubleshooting a likely scenario, dig deeper to find the cause and some possible solutions for it. The goal is to probe your knowledge of systems at scale and under load, so keep in mind the challenges of the Facebook environment.
• Focus on things such as tooling, memory management and unix process lifecycle.

Systems

More specifically, linux troubleshooting and debugging. Understanding things like memory, io, cpu, shell, memory etc. would be pretty helpful. Knowing how to actually write a unix shell would also be a good idea. What tools might you use to debug something? On another note, this interview will likely push your boundaries of what you know (and how to implement it).

Design/Architecture

Interview is all about taking an ambiguous question of how you might build a system and letting

Add --allow-privileged=true to:

# kubelet config

#kube-apiserver config

Building GCC 7.3.0 on Red Hat Enterprise Linux 7

Introduction

Red Hat Enterprise Linux (RHEL) distribution ships with a somewhat outdated version of the GCC compiler (4.8.3 on RHEL 7.1), which may not be suitable to your compilation requirements. For example, C11 - which supersedes C99 - is fully supported only starting from GCC 4.9).

Additionally, recent versions of GCC (GCC6, GCC7) come with improvements which help detect issues at build time and offer suggestions on how to fix them. Sometimes, these are even actually helpful!

This note describes how to build the latest GCC (7.3 as of January 2018) from sources on RHEL 7. This should be applicable as is on CentOS 7. For other Linux distributions, adapt as needed.
