In Ansys HPC Platform Services deployments, outbound internet access is often controlled by a corporate proxy that performs TLS inspection. These proxies terminate encrypted connections and reissue certificates signed by an enterprise root Certificate Authority (CA).
Docker image builds require HTTPS access to external container registries and package repositories to:
Pull base images
Install operating system dependencies
Retrieve application libraries
When TLS inspection is enabled, Docker operations can fail unless trust is explicitly configured. To operate correctly, trust must be established at three distinct layers:
The host operating system running Ansys HPC Platform Services
The Docker daemon responsible for pulling container images
Build‑time containers that install external dependencies
This layered trust model preserves security boundaries while allowing reliable container image builds in secured enterprise networks.
