No of pages: 15
Sub topics
1. Using Modules and Functions
2. Listing the salt module indices
3. Using salt and salt-call to execute modules4. Locate command line help
5. The big three: packages, services, and files
Chapter 6: Writing YAMLChapter Goal: Learn to write and understand YAML files. Configure your command line editor for YAML

Sub - Topics:
1. YAML Ain't Markup Language
2. Using Online Parser to process YAML
3. Configuring the nano editor
4. Configuring the vim editor for YAML and SLS files
Chapter 7: Writing Salt State Files

1. State vs Flow2. Jinja and YAML Parsing
3. Creating Jinja2 templates
4. Installing packages with Salt states
5. Managing services with state files
6. Delivering files with salt states
7. Syntax checking state files
Chapter 8: Building an effective state tree
Chapter Goal: The top.sls file can be referenced as the inverted root of the state tree to include the required states for different systems
No of pages: 8
Sub - Topics:
1. Creating the top file
2. Understanding state.sl, state.apply and state.highstate
3. Targeting in the top file
Chapter 9: Creating Reusable State Files
Chapter Goal: Learn to implement states that fit a variety of systems

Sub - Topics:
1. Using variables and Jinja
2. Using grains
3. Configuring Salt Pillar4. Using logic to remove reliance on external data
5. Speeding the process with map files
6. Accessing templated data
Chapter 10: Implementing Reactors and Beacons
Chapter Goal: The Salt Master maintain the high-speed message bus. Events are written to this bust and we can view the events to help understand and debug the salt system. Working with events we can configure the master to react to events using Reactors. This can move configuration management into the realms of orchestration. Taking this further we can configure beacons on Minions to send events to the bus when triggered by thresholds on the managed device
No of pages: 18
Sub - Topics:
1. Reading and Identify events on the event bus
2. Configuring reactors on the Salt Master
3. Configuring Beacons on Minions
Chapter 11: Using Salt-SSH
Chapter Goal: Where a long running Minion service is not desirable we can use salt-ssh to deploy configuration
No of pages: 8
Sub - Topics:
1. Salt-SSH
2. Deploy key based ssh authentication
3. Using Salt-SSH
Chapter 12: Deploy Virtual Machines Using Salt-Cloud
Chapter Goal: Using salt-cloud the single utility can be used to manage your virtual machine deployment irrespective of the cloud system used
No of pages: 10
Sub - Topics:
1. Managing VMs with salt-cloud
2. Using salt-cloud with AWS
3. Configuring providers and profiles
4. Using map files5. Managing systems
Chapter 13: Scaling Configuration Management Using Salt-Syndic
Chapter Goal: Implementing Salt-syndic you add additional masters to the system that report back to the Master or Masters. This can load balance your Minions or act to traverse a network link
No of pages: 6
Sub - Topics:
1. Installing Salt Syndic
2. Configuring Syndic on minion
3. Configuring Minions to use Syndic
Chapter 14: Automating Network Infrastructure with Salt Proxy
Chapter Goal: Salt Proxy is used to connect to devices that don’t maintain a long running Minion such as network devices
No of pages: 15
Sub - Topics:
1. Configuring Pillar Data for Proxy
2. Installing NAPALM modules
3. Configuring Proxy Systems
4. Enabling SSH on Cisco IOS
5. Configuring NTP services on Cisco Devices

Andrew is a well known Linux consultant and trainer, his YouTube Channel has over 65K subscribers and more than 1000 videos. Working mainly online now Andrew has authored courses on both Pluralsight and Udemy and regularly teaches classes online to a worldwide audience. Andrew is familiar with Linux and UNIX and has worked with them for over 20 years. Scripting and automation is one of his passions as he is inherently lazy and will always seek the most effective way of getting the job done. The Urban Penguin, his alter-ego, is a UK based company where his work is created from and currently employs 5 people.
There is a rapid growth of automation in server rooms and data centers. The days of having many administrators running around busily configuring and maintaining servers are gone and have been replaced with droves of Salt-Minions; agents beavering away on the target nodes ensuring the configuration is as specified. This book covers Salt Open (also known as SaltStack Open) from the ground up and shows you how to work with two Linux distributions.
You'll see how Salt Open is duplicated with ArubaOS and IOS networking devices, which can be configured without the underlying OS. As you step through the configuration options, you'll learn how to run remote execution modules from the CLI before looking at stateful configuration using SLS files. Moving on, you'll learn how to configure the systems where you also need to monitor your devices and that is when reactors and beacons come into play. Creating beacons to alert the server when thresholds are exceeded, you will be able to create reactors to mitigate the issues identified by the beacons.
By the end of this book, you will be able to deploy Salt to your servers and network infrastructure. You will be able to install the Salt-Master and Salt-Minion, executing commands from both the Master and the Minion. The networking devices you need to manage will be controlled through the Salt_Proxy Minions that you have configured. Finally, you will be able to load-balance connections to the master with Salt-Syndic.
You will:
- Install Salt Services on Ubuntu and CentOS based systems
- Work with remote execution modules
- Format YAML files correctly
- Provide defined configuration using state files
- Use Salt-Proxy to configure network devices
- Automate the configuration of Linux servers and networking devices
- Providing value for both the server and network automation team
