Hello guys, I'm unable to pass a dynamic inventory script to read a yml file from repo

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 staging.yml
{
“_meta”: {
“hostvars”: {}
},
“db”: {
“children”: [
“db-site2”,
“db-site1”
]
},
“db-site1”: {
“hosts”: [
“bary785c.mylabserver.com”,
“bary786c.mylabserver.com”
]
},
“db-site2”: {
“hosts”: [
“bary783c.mylabserver.com”,
“bary785c.mylabserver.com”
]
},
“site1”: {
“children”: [
“staging-site1”
]
},
“site2”: {
“children”: [
“staging-site2”
]
},
“staging”: {
“children”: [
“web”,
“db”
]
},
“staging-db”: {
“children”: [
“db”
]
},
“staging-db-site1”: {
“children”: [
“db-site1”
]
},
“staging-db-site2”: {
“children”: [
“db-site2”
]
},
“staging-site1”: {
“children”: [
“web-site1”,
“db-site1”
]
},
“staging-site2”: {
“children”: [
“web-site2”,
“db-site2”
]
},
“staging-web”: {
“children”: [
“web”
]
},
“staging-web-site1”: {
“children”: [
“web-site1”
]
},
“staging-web-site2”: {
“children”: [
“web-site2”
]
},
“web”: {
“children”: [
“web-site2”,
“web-site1”
]
},
“web-site1”: {
“hosts”: [
“bary781c.mylabserver.com”,
“bary782c.mylabserver.com”
]
},
“web-site2”: {
“hosts”: [
“bary783c.mylabserver.com”,
“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 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

[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.

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.

  #!/bin/sh/
  ${INVPATH}/inventory.py https://github.com/adeyeri88/test.git staging.yml

and use it in the command

  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 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 staging.yml

#${ INVPATH}/inventory.py 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
