SLC DevOps Days 2017

• https://kubernetes.io
• http://rancher.com
• https://www.ansible.com

• Run `docker pull ryanwalls/ansible-aws:v2.2.1.0-1-k8s`
• Create an access key and secret for deploying into AWS.  See http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html.  User should be a power user or admin privileges.  
• (Optional) If you want to create your own Rancher server, then you'll need to have an SSL cert for a domain you control--ideally a domain whose nameservers are on AWS Route53.  See https://aws.amazon.com/blogs/aws/new-aws-certificate-manager-deploy-ssltls-based-apps-on-aws for how to create a free SSL cert using AWS Certificate Manager.  Feel free to use a domain like, rancher.yourdomain.com if you don't want to setup a wildcard cert.  Note: Setup the cert in US East (N Virginia).  Some AWS products can only read certs from that region.
• Create a key pair to use for SSH access in AWS.  See http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html#having-ec2-create-your-key-pair
• You should try launching a t2.medium instance in your AWS account at least 2 hours beforehand.  When I tried launching anything other than a t2.micro instance, AWS said they had to "validate" my account and that it could take a couple hours.  

• Run InSpec locally on a machine
• Run InSpec on a remote machine
• Use InSpec in the Chef cookbook development process for integration testing

• Writing code (of just about any flavor) in a text editor
• Working on the command line
• Basic system administration – installing packages, configuring those packages, starting service

Introduction to ElasticSearch, Kibana, Logstash

Requirements

Vagrant with centos/7 box downloaded and installed

Overview

In this course we will go over the basics of standing up an ElasticStack node. We will cover the  setting up elasticsearch, Kibana, Kafka, and logstash, going over how to ship, parse and visualize the log files and twitter data, finally showing how post notifications into slack.

Elasticsearch

Elasticsearch is a distributed, RESTful search and analytics engine capable of solving a growing number of use cases. As the heart of the Elastic Stack, it centrally stores your data so you can discover the expected and uncover the unexpected.

Kibana

Kibana lets you visualize your Elasticsearch data and navigate the Elastic Stack, so you can do anything from learning why you're getting paged at 2:00 a.m. to understanding the impact rain might have on your quarterly numbers.

Logstash

Logstash is an open source, server-side data processing pipeline that ingests data from a multitude of sources simultaneously, transforms it, and then sends it to your favorite “stash.” (Ours is Elasticsearch, naturally.)

Please note, that we will be utilizing Elasticsearch 5.3.2 which requires java 8, it is recommended that you download and install this in your vagrant centos7 box prior to the start of the workshop, as it can be a lengthy process.

In this workshop, we will setup a few docker images that will form a basic monitoring stack. This stack can be used for tracking and graphing just about any type of metric you may need, including application statistics, os performance statistics, etc.

Workshop participants will learn

• How do download the InfluxDB Image and configure the administrative interface for troubleshooting
• How to download the Telegraf Image and configure it to talk to InfluxDB and to listen for StatsD metrics
• How to use nc to send sample metrics to InfluxDB
• The differences between common metric types
  • Gauges
  • Counters
  • Timings and Histograms
• How to add tags to your statsd metrics
• How to download the grafana image and configure it to use InfluxDB
• How to create dashboards in grafana
• How to parameterize your dashboards

This is not a Docker introduction, but in order to keep the workshop functional on as many devices as possible we will be using Docker to get up and running quickly. The instructor will be using Docker for Mac (versions listed below). You can follow this link to ensure your docker installation is functional before the workshop. Please complete the installation for your device and complete the Hello World example, as well as check the version to ensure you are setup for a successful learning experience.

• Docker 17.03.1
• Docker Compose 1.11.2
