A large financial institution has recently migrated its data center network to a new Cisco ACI fabric. The operations team is tasked with automating the provisioning of new application tenants, including EPGs, contracts, and bridge domains, using the APIC REST API. They have developed a comprehensive set of Python scripts that successfully performed these actions in their lab environment. However, when deploying the scripts to production, they receive an 'SSL: CERTIFICATE_VERIFY_FAILED' error from the requests library. The production APIC cluster uses a self-signed certificate for HTTPS, and the corporate security policy strictly prohibits the use of HTTP or disabling certificate verification. Additionally, the policy does not allow replacing the self-signed certificate with a CA-signed one without a lengthy approval process that could delay the automation project.
