I echoed all my env variables and they're there, but when I try to read them from command section, they are empty.
command:
- /bin/sh
- -c
- >
if [ ! -f /data/db/admin-user.lock ]; then
echo "KUBERNETES LOG $HOSTNAME - no Admin-user.lock file found yet" >> /data/db/configlog.txt;
env >> /data/db/configlog.txt;
while (! mongo --eval "db.adminCommand('ping')"); do sleep 10; echo "KUBERNETES LOG $HOSTNAME - waiting another 10 seconds for mongo to start" >> /data/db/configlog.txt; done;
touch /data/db/admin-user.lock
echo "KUBERNETES LOG $HOSTNAME - try create user with user=$MONGODB_CREATE_USER and pass=$MONGODB_CREATE_PASSWORD..." >> /data/db/configlog.txt;refer the below sample
