Unlike host lines, :vars sections accept only a single entry per line, so everything after the = must be the value for the entry. For example var=FALSE would create a string equal to ‘FALSE’. When declared in a :vars section, INI values are interpreted as strings. See the Python shlex parsing rules for details. Values that contain whitespace can be quoted (single or double). Therefore they need a way to indicate that a space is part of a value rather than a separator. Host lines accept multiple key=value parameters per line. When declared inline with the host, INI values are interpreted as Python literal structures (strings, numbers, tuples, lists, dicts, booleans, None). Values passed in the INI format using the key=value syntax are interpreted differently depending on where they are declared: When - The development stage, to avoid testing on production resources (for example, prod, test).Įxtending the previous YAML inventory to include what, when, and where would look like: Where - A datacenter or region, to talk to local DNS, storage, and so on (for example, east, west). What - An application, stack or microservice (for example, database servers, web servers, and so on). For example a production webserver in a datacenter in Atlanta might be included in groups called and and. You can (and probably will) put each host in more than one group. Though all and ungrouped are always present, they can be implicit and not appear in group listings like group_names. The ungrouped group contains all hosts that don’t have another group aside from all.Įvery host will always belong to at least 2 groups ( all and ungrouped or all and some other group). There are two default groups: all and ungrouped.
