Learn it fast and learn it well. It provides an arsenal of tools to execute commands across thousands of systems with ease. Learning Saltstack will start from scratch and build towards a high-level goal of installing, configuring, deploying, and managing a web application to Docker containers across multiple systems behind a HAProxy load balancer.
The course will start by explaining how Salt approaches System management and help the viewer get up and running with a working Salt infrastructure. You will learn how to use Salt to target, query, and change systems. You will learn to define the desired state of your infrastructure and how you can use Salt to enforce the state with a single command. The course will dive deeper into YAML and Jinja and show you the best practices for writing reusable and maintainable states.
By the end of the course, you would be able to build and manage your infrastructure and fully utilize its potential.

Note that you can actually use sys. The sys module is going to be one of the most useful modules in your quest to learn Salt. Keep it handy and turn to it any time you want to learn more about something you're working with. Remember that the sys module can target itself. The following code shows you how to use the sys module:. We are going to discuss remote execution and the execution modules in much greater detail in the next chapter.
In this chapter, we've taken the time to set up Salt in a master-minion relationship. This will allow us to take advantage of all the power of Salt and scale to multiple minions easily later on. However, Salt is also designed such that a minion can run without a master.
We'll run through a few examples of how to run commands on a minion. This will also be useful even when we do have a master because, if we're logged into a minion for some reason and want to run a command while we're there, we can do so using these same concepts. To start, we'll leave our master running.
The command for running commands on the minion is salt-call , and it can take any of the same execution module functions that we used with the salt command, as follows:. The example shown previously will take a fairly long time to terminate. Basically, salt-call is trying to establish a connection with the master just in case it needs to copy files from the master or other similar operations. To get salt-call to operate properly masterless, we need to tell it there's no master. We do this with the --local flag, as follows:.
We've covered a lot of ground in this chapter. We've installed the Salt minion and Salt master on our machines and configured them to talk to each other, including accepting the minion's key on the master. We've also run our first Salt commands, both from the master and from the minion without involving the master.
However, we've only just begun! In the next chapter, we're going to go much more in-depth into the topic of remote execution and show how powerful this tool is. He loves working on open source software and has made multiple appearances as a speaker at the US PyCon conference. He was previously a core engineer at SaltStack.
At the time this book was published, he was a Python developer and systems engineer at Adobe. About this book SaltStack is one of the best infrastructure management platforms available.
