See vars plugins docs for details on 'stage'. - Implicit groups, such as 'all' or 'ungrouped', need to be explicitly defined in any previous inventory to apply the corresponding group_vars required: false default: false type: boolean version_added: '2.11' extends_documentation_fragment: - constructed a # inventory.config file in YAML format plugin: ansible.builtin.constructed strict: False compose: var_sum: var1 + var2 # this variable will only be set if I have a persistent fact cache enabled (and have non expired facts) # `strict: False` will skip this instead of producing an error if it is missing facts. server_type: "ansible_hostname | regex_replace ('(.{6})(.{2}).*', '\\2')" groups: # simple name matching webservers: inventory_hostname.startswith('web') # using ec2 'tags' (assumes aws inventory) development: "'devel' in (ec2_tags|list)" # using other host properties populated in inventory private_only: not (public_dns_name is defined or ip_address is defined) # complex group membership multi_group: (group_names | intersect(['alpha', 'beta', 'omega'])) | length >= 2 keyed_groups: # this creates a group per distro (distro_CentOS, distro_Debian) and assigns the hosts that have matching values to it, # using the default separator "_" - prefix: distro key: ansible_distribution # the following examples assume the first inventory is from the `aws_ec2` plugin # this creates a group per ec2 architecture and assign hosts to the matching ones (arch_x86_64, arch_sparc, etc) - prefix: arch key: architecture # this creates a group per ec2 region like "us_west_1" - prefix: "" separator: "" key: placement.region # this creates a common parent group for all ec2 availability zones - key: placement.availability_zone parent_group: all_ec2_zones N) constants)AnsibleParserErrorAnsibleOptionsError)get_group_vars)BaseInventoryPlugin Constructable) to_native) combine_vars) FactCache)get_vars_from_inventory_sourcescNeZdZdZdZfdZfdZdZdZdZ d fd Z xZ S) InventoryModulez> constructs groups and vars using Jinja2 template expressions constructedcHtt| t|_y)N)superr__init__r _cache)self __class__s U/home/dcms/DCMS/lib/python3.12/site-packages/ansible/plugins/inventory/constructed.pyrzInventoryModule.__init__cs ot-/k cd}tt| |rwxYw#t $r+} t#d t%|d t%| d | d} ~ wwxYw)z parses the inventory file )cacher-z5The option use_vars_plugins requires ansible >= 2.11.strictcompose)r7groupsF)r7fetch_hostvars keyed_groupszfailed to parse z:  )orig_excN)rrparse_read_config_dataprocessed_sourcesAttributeErrorr0rr hostsr*r _set_composite_varsr_add_host_to_composed_groups_add_host_to_keyed_groups Exceptionrr ) r inventoryr(rr6r)r7 fact_cacher'hostvarsers rr>zInventoryModule.parses ot*9fd%*P t$ c11G *[  n!
