Hey Racke,
I've changed the output to a list now so we can put the json format to bed
hopefully now:
$ ansible --version
ansible 2.9.15
config file = /home/ubuntu/ansible.cfg
configured module search path =
[u'/home/ubuntu/.ansible/plugins/modules',
u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/dist-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.17 (default, Sep 30 2020, 13:38:04) [GCC 7.5.0]
$ ./dynamic3.sh
{
"all": {
"hosts": [
ip-172-31-10-247.eu-west-1.compute.internal,
] }
}
on ansible version - v2.9.15 I get this output:
$ ansible -i dynamic3.sh all -m ping -u ubuntu
[WARNING]: * Failed to parse /home/ubuntu/dynamic3.sh with script plugin:
failed to parse executable inventory script results from
/home/ubuntu/dynamic3.sh: No JSON
object could be decoded
[WARNING]: * Failed to parse /home/ubuntu/dynamic3.sh with ini plugin:
/home/ubuntu/dynamic3.sh:2: Expected key=value host variable assignment,
got: {
[WARNING]: Unable to parse /home/ubuntu/dynamic3.sh as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note
that the implicit localhost does not match 'all'
But the same script on ansible version v2.9.6
$ ansible --version
ansible 2.9.6
config file = /home/ubuntu/ansible.cfg
configured module search path =
[u'/home/ubuntu/.ansible/plugins/modules',
u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/dist-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.17 (default, Sep 30 2020, 13:38:04) [GCC 7.5.0]
$ ./dynamic.sh
{
"all": {
"hosts": [
ip-172-31-10-247.eu-west-1.compute.internal,
] }
}
$ ansible -i dynamic.sh all -m ping -u ubuntu
[DEPRECATION WARNING]: Distribution Ubuntu 18.04 on host
ip-172-31-10-247.eu-west-1.compute.internal should use
/usr/bin/python3, but is using /usr/bin/python for backward compatibility
with prior Ansible releases. A future
Ansible release will default to using the discovered platform python for
this host. See
https://docs.ansible.com/ansible/2.9/reference_appendices/interpreter_discovery.html
for more information. This
feature will be removed in version 2.12. Deprecation warnings can be
disabled by setting deprecation_warnings=False
in ansible.cfg.
ip-172-31-10-247.eu-west-1.compute.internal | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
and it works? Is anyone able to tell me the difference? You help would be
greatly appreciated.
