Welcome to 'getting started with salt-workspace'. Hopefully this, in combination with the salt-workspace git repo will help you get familiar with Salt and its structure in an easy to follow manner.
If you haven't already, follow the Readme instructions to get the workspace pre-requisites done, then come back here for the first lesson.
you can look in the Vagrantfile for more information; this workspace will support:
- Centos 6 or 7 (bento/centos-7.3 is the default)
- Ubuntu 14.04 or 16.04
- Windows Server 2012r2
- Default ram is 512mb, but can be configured with the
LINUX_BOX_RAMenvironment variable, for example to have 1gb ram:
- Default is 1 'linux' VM, but you can use the
LINUX_MINION_COUNTenvironment variable to spin up as many as you have resources for, for example you can have 3 linux VM's by typing:
- Salt version can be overridden with
These are the most common changes you might want to make, again you can reference the Vagrantfile for the rest of the available options.
Now that you've got the workspace environment variables set up, try the following:
The make all command copies the salt files to ./dist which is sync'd to the salt master /srv directory, which is then designated by the file roots in the salt master configuration file. After you see
Salt is ready in ./dist. Enjoy! you can do the following:
vagrant up saltmaster linux-1
This will bring up a centos 7 based salt master and minion VM (Assuming you didn't change the
LINUX_VERSION env variables). Note, that you can do everything on one VM (the saltmaster) if you're constrained on resources. However for the purposes of this tutorial, I'll assume you're running the two VM's.
Next, to verify things are running properly, you can type
$ vagrant status Chose image bento/centos-7.3 from (default) args LINUX_DISTRO=centos LINUX_VERSION=7 Current machine states: saltmaster running linux-1 running
Notice how we default to the bento/centos-7.3 image, and as I've got no env variables set, we only have a 'saltmaster' and 'linux-1' minion up.
Next, lets go log into the salt master and poke around a bit
vagrant ssh saltmaster [[email protected] ~]$ sudo salt \* test.ping linux-1: True saltmaster: True
Next, we ensure the highstate runs properly - run it first like this:
sudo salt \* state.highstate (the \* tells it to run on all minions)
[[email protected] ~]$ sudo salt \* state.highstate saltmaster: ---------- ID: motd Function: file.managed Name: /etc/motd Result: True Comment: File /etc/motd is in the correct state Started: 05:13:13.237969 Duration: 4.902 ms Changes: Summary for saltmaster ------------ Succeeded: 1 Failed: 0 ------------ Total states run: 1 Total run time: 4.902 ms linux-1: ---------- ID: motd Function: file.managed Name: /etc/motd Result: True Comment: File /etc/motd is in the correct state Started: 05:13:13.697753 Duration: 3.259 ms Changes: Summary for linux-1 ------------ Succeeded: 1 Failed: 0 ------------ Total states run: 1 Total run time: 3.259 ms
As you can see here, we only have 1 state being applied, which is setting an MOTD, using a very basic formula, pillar and example of a role. In later blog posts we'll discuss each of these pieces in depth.
Once you're happy with the ability to spin up and log into (and tinker around with!) your Vagrant boxes, you can log out of the salt master by pressing ctrl+D or, typing
exit. Once you're back at your computers command prompt you can type
vagrant destroy saltmaster linux-1 to remove the old VM's.
This concludes the getting started blog post. If you have any issues spinning up this environment you can submit an issue or comment below with the error you're experiencing.
Next up, a look at the difference between Formulas and Roles, and how we can use Pillar data to modify both.
Thanks for checking this guide out!
