@jtschladen @kevgliss Hi! I’m following up on this as it resolves Issue #73 regarding the acme dependency failure. Since the current Dockerfile can no longer build successfully, this PR patches the environment (Ubuntu 22.04 + Node 20) to get it working again. Merging this would resolve the blockers for the community currently trying to deploy Lemur via Docker. Thanks! |
