Slow build times, usually related to upgrades

Post upgrade to 4.5.1 or a later Domino 4 version the build process is very slow

Environment

Domino 4.5.1-4.6.X

Issue

When running in EKS and building a large image it may be very slow. For each layer Forge is designed to copy out the current layer + all previous layers. To make it faster, it needs to be configured to enable the privileged mode (overlayfs) as described in https://admin.dominodatalab.com/en/4.5.2/installation/release-notes.html#fleetcommand-agent-v30-december-2020.

Resolution

Add the following config to domino.yaml and reinstall/update forge:

services:
  forge:
    chart_values:
      config:
        fullPrivilege: true
