Hi all, I have just discovered ansible and I must admit in certain tasks it this way easier to use ansible than puppet 🙂 It is really stunning how easy are some tasks - thanks guys 🙂 I am trying to get some data from nodes. I have just run > ansible -m setup node100 but I get output in json (I guess): > node100 | success \>\> { > “ansible\_facts”: { > “ansible\_all\_ipv4\_addresses”: [ > “x.x.x.x” > ], > “ansible\_architecture”: “x86\_64”, > … > … Is there any **easy** way to read data from particular fields, i.e.: var1 = ansible\_facts → ansible\_all\_ipv4\_addresses Python-native way: (var1, var2, var3) = (ansible\_facts → ansible\_all\_ipv4\_addresses, ansible\_facts → …, ansible\_facts → …) would be ideal 😉 Thanks Przemek ---

If you want to use this in a playbook or template, this is pretty straightforward. Jinja2 evaluation is basically Python. The only thing is you can’t do list comprehensions. First element: {{ ansible\_all\_ipv4\_addresses[0] }} ---

At first I wanted to use it in the CLI (listing some facts about nodes) so I guess I need to download some external json parser. Am I right ? Regarding using it in a playbook/template: can you provide simple but full example how to use it ? ---

Does anybody know how to parse the output from the following command ? ansible groupofhosts -m setup -a ‘filter=some\_filter’ ? ---

To gather config data from nodes for further analysis. ---

Ok, so the API is great for that. You also have --tree mode to dump things into individual JSON files per host. ---

Where I could read about it ? Any example program ? ---

ansible with the --help flag, then just try the option. It will output JSON files into the specified directory with one file per hostname. ---

Oh I see Michael - I am testing the “tree” option now 🙂 I was asking about API: docs + examples. ---

Yeah /usr/bin/ansible is a pretty self explanatory example of the Runner API. I would look at that closely.
