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.
