New to Ansible. Looking for help with orchestrating actions which depend on the state of applications on other servers. Can this be done in Ansible?
Scenario:
server 1 running app 1
server 2 running app 2
server 3 running app 3
Need to stop app2 on server 2 but app 2 must not be stopped if either app 1 or app 3 is up - app1 and app 3 are client apps which would crash if app2 was brought down
i.e. need to know the state of app 1 and app 3 at the time a stop of app 2 is attempted to make a decision whether to proceed or not
In other words can the state of multiple components on various servers be maintained and tested before an action is performed. Essentialy a state machine paradigm.
Any help appreciated.
