Installing outlet on metal pole

[Steve Siegrist]

Wanting to install a single GFCI outlet in/on exterior pergola support post. Post is 6" square METAL. Hoping for guidance on how to accomplish. Will need to be weatherproof with in-use cover. Is there a "special" single gang box for this application? How would it mount?
