Hello all ..  I am trying to get the zhmc collection to work with our Z CPC's.    We have installed  CA signed certs on all of our HMC's so it seems like zhmcclient is being called by the playbook just fine but ends up getting a connection error - I assume because it needs to be using a CA signed cert for the https call.    How/Where do I install the certificate on my Ansible system so zhmclient uses our CA signed cert for the connection?   Thanks .. 

Hi Dan - the way I got it to work (using RHEL) iwas to download the full certificate path via openssl and copy them (in crt format)  into the /etc/pki/ca-trust/source/whitelist directory if you are using the curl certificate store, and then run a 'update-ca-trust' command import it. To check if it works, enter a 'openssl s_client -connect example.com:443' command as an example with your hmc url and you should get a valid response back.

Finally in your playbook, set verify to true and in the following line define 'ca_certs: /etc/pki/tls/certs/ca-bundle.crt' to look in your curl certificate whitelist for authentication.

Hope that helps!

Hi Dan,

Thanks for using our ibm.zhmc modules for automation. 

You can install the certificate in any directory and use one of the method to expose this certificate path using the "ca_certs" and "verify" Parameters mentioned in our ibnm.zhmc modules documentation. 
E.g., Refer here :  https://zhmcclient.github.io/zhmc-ansible-modules/modules/zhmc_session.html. 

To answer your question in short, these are the ways you can try:
*         verify=true (default), ca_certs omitted: path in REQUESTS_CA_BUNDLE, path in CURL_CA_BUNDLE path, or certifi package is used for validation
*         verify=false, ca_certs omitted: no validation
*         verify=true, ca_certs specified: path in ca_certs is used for validation

Please let us know if you have any questions.

Regards,


Kathir
