*This is a question of good practise:* I do have logic "Lines" on a way from my LB to Backend
[LineA] > proxyA app_type=proxy > frontendA app_type=frontend > middlewareA app_type=middleware > > [LineB] > proxyB app_type=proxy > ... Since the apps are more complex than simple apache start stop. i did write custom modules with required logic to controll them: > *proxysrv: with actions [suspend, activate]**restart: with actions > [start, stop, restart], and app_type arguments [frontend, middleware]* The tasks have to be played in certain order (suspend proxy, restart frontends and middleware, activate proxy) Now I can have a play like: --- > - hosts: LineA > - tasks: > - name: > proxysrv: action=suspend, when app_type =='proxy' > - name: > restart: action=restart, app_type=frontend, when app_type > =='frontend' > - name: > restart: action=restart, app_type=middleware, when app_type > =='middleware' > - name: > proxysrv: action=activate, when app_type =='proxy' I don't like the "skipped" message during the run of a playbook, and the numbers in the final play statistics, that count the skipped hosts (as not changed). *This is a question of good practise:* How would You create dependencies, that would apply specialized tasks on a subset of Your hosts group. I guess that better way to solve the problem would be the use of *delegate_to* (probably with "*with_items*" or "*tags*"). I could register the 'proxy_hosts', 'frontend_hosts', 'middleware_hosts' variables during an execution of the play and run tasks against them. I do not see yet use of tags here, the example would be nice. Any better idea? What about roles. I would like to have a roles (proxy, restart role) and run them against subset of a hosts. -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
