#TIL : Ansible running host pattern

til ansible devops

Ansible supports pattern to select and filter running hosts from all hosts. Here is some common pattern

  • * : wildcard, standalone mean all
  • group1,group2 : run hosts belong to group1 or group2
  • *.web : run hosts belongs to group matches pattern. Ex: backend.web, frontend.web
  • all:!abc : run all hosts exclude hosts belongs to group abc

Infrastructure by code ;)
