2/18/2024

This post details the technical steps and configurations required to adapt Rancher Desktop for running IBM Edge Application Manager (IEAM) edge agents on macOS. It outlines the creation/update of the `~/Library/Application Support/rancher-desktop/lima/_config/override.yaml` file with specific mount configurations (`mountType: 9p`, `mounts` for `/private/var/tmp`, `/private/etc/default`, `/private/etc/horizon`) and the selection of the '9p' volume type in Rancher Desktop's Virtual Machine preferences. These customizations enable the IEAM edge agent to run as a Docker container on macOS.
