reconstructed example
The example in this directory generates a graph of hosts, organised based on
the contents of a variable called inv__data
associated to each host
statically in the inventory/00-data.yml
file. The main reconstructed
script, located in inventory/01-test-reconstructed.yml
, is executed once
for each host. It creates the various groups at the appropriate locations,
defines additional facts, and adds hosts to the groups.
The example can be executed using :
ansible-galaxy collection install .. -p ./collections
ansible-inventory --playbook-dir . --graph
When executed, localhost
will be skipped as it doesn't have the
inv__data
fact.
Two hosts in there, evil-vm
and evil-but-nicer-vm
, are meant to
illustrate the fail
action as well as error recovery.
The rest of the hosts correspond to two instances of a LDAP cluster, in which two hosts are used as the frontend, two hosts as the read-only replicas, and the last one as the master. Groups are generated based on the environment, network, and failover stack, as well as service, components of the service, and instances of a service.
Below is the output that should be obtained.
[WARNING]: reconstructed - error on host evil-vm: evil-vm is obviously evil,
skipping.
