# rs.initiate() is playing 2 roles:
# * required for my local mongo setup
# * it can also be used to test a connection but you can use almost any other evaluation command. 

# The command below runs a mongo check in a loop and times out after a minute.
# Why not use "wait-for-it.sh"? That establishes a tcp connection check but you could still run into a connection error
# if you run a single mongo connection check so we still need to loop.
timeout -v 1m bash -c 'until docker exec -it mongo mongo --eval "rs.initiate()"; do sleep 3; done'
