From f0d3cb4797e9613dc565782b14ef19ab6e494ffb Mon Sep 17 00:00:00 2001 From: Franck Cuny Date: Thu, 15 Apr 2021 19:40:00 -0700 Subject: add a lease to the Go context This will ensure that our container will not be deleted while we work on it. In addition, a default expiry of 24 hours will be set on it once the lease is released (once the program is completed). See [1] for more details.
