Subject: Check if ${NOMAD_DC} is undefined or unset
X-Git-Tag: v0.57.1^0
X-Git-Url: https://gerrit.linuxfoundation.org/infra/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F74%2F65274%2F5;p=releng%2Fglobal-jjb.git

Check if ${NOMAD_DC} is undefined or unset

The condition in the commit 31a4b7fc00fe90494b6efb512ad0f1db02481ff3
should instead check when the environment variable $NOMAD_DC is not
defined or unset, this avoids the script from exiting without capturing
instance metadata.

Issue: RELENG-3142
