Requisites: difference between require and require_in in SaltStack
Lets see require vs require_in SaltStack. The Salt requisite system is used to create relationships between states. You can find more details about Requisites on here
require vs require_in SaltStack:
require:
- This is the most basic requisite which allows us to specify that one state requires another state to be run successfully first.
- Also ensures correct ordering and the requiring states runs only if the required state ran successfully.
Ex:
# cat req.sls
require_check: # REQUIRING STATE
cmd.run:
– name: echo FIRST
– require:
– cmd: require_check1
require_check1: # REQUIRED STATE
cmd.run:
– name: echo SECOND
If the REQUIRED STATE not successful:
require_in:
- Requisites of this form( _in ) force other states to depend on the state that contains the requisite.
- The requiring states run first and then run the required state if requiring state run successful.
Ex:
# cat req.sls
require_check: # REQUIRING STATE
cmd.run:
– name: echo FIRST
– require_in:
– cmd: require_check1
require_check1: # REQUIRED STATE
cmd.run:
– name: echo SECOND
If the REQUIRING STATE not successful:
