I’m able to get the list of my hosts from the yml file when running this command

$ /opt/ansible/static/inventory/inventory.py [https://github.com/adeyeri88/test.git](https://github.com/adeyeri88/test.git) staging.yml  
{  
“\_meta”: {

]  
},  
“site1”: {  
“children”: [  
“staging-site1”  
]  
},  
“site2”: {  
“children”: [  
“staging-site2”  
]  
},  
“staging”: {  
“children”: [  
“web”,

]  
},  
“staging-db”: {  
“children”: [

},

},  
“staging-site1”: {  
“children”: [

},  
“staging-site2”: {

“web-site1”: {  
“hosts”: [  
“[bary781c.mylabserver.com](http://bary781c.mylabserver.com)”,  
“[bary782c.mylabserver.com](http://bary782c.mylabserver.com)”  
]  
},  
“web-site2”: {  
“hosts”: [  
“[bary783c.mylabserver.com](http://bary783c.mylabserver.com)”,  
“[bary784c.mylabserver.com](http://bary784c.mylabserver.com)”  
]  
}  
}

But when I’m trying now to run any ansible command to call the same file, I’m getting this error.

]$ ansible -i /opt/ansible/static/inventory/inventory.py all -m ping -e “[https://github.com/adeyeri88/test.git](https://github.com/adeyeri88/test.git) staging.yml”  
[WARNING]: \* Failed to parse /opt/ansible/static/inventory/inventory.py with script plugin: Inventory script (/opt/ansible/static/inventory/inventory.py) had an execution error: usage: inventory.py [-h] [–sshkey SSHKEY] [–commit  
COMMIT] url inventory inventory.py: error: too few arguments

[WARNING]: Unable to parse /opt/ansible/static/inventory/inventory.py 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’

Please can you help me here?

Extra variables (-e, --extra-vars) are passed to the play not to the dynamic  
inventory script. Create a wrapper for inventory.py with the parameters.

Cheers,

Thanks for your response. Where do I have to create the wrapper file? (is it in ansible.cfg) file.

For example create a script inventory.sh.

&nbsp;&nbsp;#!/bin/sh/  
&nbsp;&nbsp;${INVPATH}/inventory.py [https://github.com/adeyeri88/test.git](https://github.com/adeyeri88/test.git) staging.yml

and use it in the command

&nbsp;&nbsp;ansible -i inventory.sh all -m ping

Hello boss. Here is what happened. when I use the Variable same you describe, I got an error. It seem I need to define INVPATH as variable. but I don’t know where.

[ansible@bary782c ~]$ ansible -i inventory.sh all -m ping

[WARNING]: \* Failed to parse /home/ansible/inventory.sh with script plugin: Inventory script (/home/ansible/inventory.sh) had an execution error: /home/ansible/inventory.sh: line 4: ${ INVPATH}/inventory.py: bad substitution

[WARNING]: Unable to parse /home/ansible/inventory.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’

and this the script

#!/bin/bash

${ INVPATH}/inventory.py [https://github.com/adeyeri88/test.git](https://github.com/adeyeri88/test.git) staging.yml

as you gave me. But when I comment out that line and specified all the path in the script like this

#!/bin/bash

/opt/ansible/static/inventory/inventory.py [https://github.com/adeyeri88/test.git](https://github.com/adeyeri88/test.git) staging.yml

#${ INVPATH}/inventory.py [https://github.com/adeyeri88/test.git](https://github.com/adeyeri88/test.git) staging.yml

AND now run the the ansible command as you suggest it works

[ansible@bary782c ~]$ ansible -i inventory.sh all -m ping
