cannot load nodes list - missing python dependencies? about rundeck-rancher

[raffaeleguidi]

nope, I added the python deps with apt-get into the running container and restarted it. Managed to get a python stack trace, though:

Hi.
Thank for using this module.
Can you tell me your rancher version (and API version) please ?

Did you try the plugin outside rundeck ?
Using "scripts/test_container_resource_model.sh", you can check the link with rancher from a simple bash.
Can you try using the test script and send me:

• console output
• your value for: RD_NODE_RANCHER_URL
• your value for : RD_CONFIG_ENVIRONMENTS_IDS
  Don't forget to add the api version in the rancher URL (like: https://rancher.com/v1)

Are you able to reach "http://yourrancher.com/v1/projects/" using a simple
curl like :
curl -X GET \ https://yourrancher.com/v1/projects/ -H 'accept: application/json' -H 'authorization: Basic XXXXXXX=='
You need to replace XXXXXX== by the base64 encoding of "RANCHER_ACCES_KEY" concatenated with "RANCHER_SECRET_KEY" using a ":" (a colon) as separator.

Regards.
(I won't be here the next week)

yes, I tried from inside the container and use the api with other applications (jenkins) on the same server

Did you try the plugin outside rundeck ?
scripts/test_container_resource_model.sh"

where exactly the file is located?

[raffaeleguidi]

ok, found the file but I have to modify it to adapt to my environment. Gimme some minutes

Rancher is v1.6.3

[raffaeleguidi]

I can confirm that, adapting the script to run from the docker host and putting the correct values into the environment variables, everything works fine and it returns the list of my containers - but I still have to figure out how to launch the .sh from within the container. Where are the python scripts located in the installed version?

[raffaeleguidi]

got it! the url was wrong, I edited your examples and the url contained a "home" that mislead me. Now It works fine, I just suggest some more logging to improve investigations in case of configuration mistakes.

Thanks a lot,
Raffaele
