Configuration
In your Salt master or Salt minion configuration, Salt engines are set up under an engine's top-level section. Under this section, mention the machines and parameters.
engines:
- logstash:
host: log.my_network.com
port: 5959
proto: tcp
By providing the engine module parameter in the engine configuration, it is possible to configure many instances of a specific Salt engine.
engines:
- production_logstash:
host: production_Log.myNetwork.com
port: 5959
proto: tcp
engine_module: logstash
- develop_logstash:
host: develop_log.myNetwork.com
port: 5959
proto: tcp
engine_module: logstash
The Salt path must contain Salt engines, or you can add the engine's dirs option to your Salt master setup with a list of folders Salt should look in. The format for this option should be a list of directories to search, like
engines_dirs:
- /home/bob/engines
Writing an engine
The Salt source code includes a sample Salt engine on GitHub. The start() function must be implemented in your module to create an engine.
Frequently Asked Questions
Can SaltStack support managed file backups?
Yes, SaltStack does allow for controlled file backups.
What defines SaltStack as open-source software?
From a student's perspective, Salt (also known as SaltStack) is considered an open-source program because customers can download and use Salt or SaltStack for free as a stand-alone product. It was created using contributions approved by the specific community to advance the project. Hence it is termed open-source software.
Can SaltStack be described as open-core?
The answer to the earlier query is "no." SaltStack cannot be referred to as open-core. It is devoted and fully committed to being open-source software. The software was created using the Apache 2.0 license. As a result, it may be used in both proprietary and open projects.
What is SaltStack's drawback?
SaltStack lacks a user interface with many features. As a result, users use the command-line tool appropriately to complete their duties.
What is the advantage of saltstack?
With one minion that can command others, SaltStack can be set up in a tiered configuration to achieve load balancing and boast redundancy.
