Passing extra options to the Mongo driver
It's possible to provide extra connection settings to the Mongo driver by setting the
MONGO_OPTIONS environment variable to a JSON string, e.g.:# we need to pass the contents of PEMs, etc in a format compatible with JSON, so add '\n' to the end of each line.
export TLS_CRT=$(cat /pems/tls.crt | awk '{printf "%s\\n",$0} END {print ""}')
export PEM=$(cat /pems/mongo.pem | awk '{printf "%s\\n",$0} END {print ""}')
export KEY=$(cat /pems/mongo.key | awk '{printf "%s\\n",$0} END {print ""}')
# now insert all the credentials into the JSON OPTIONS string
export MONGO_OPTIONS='{"sslCA":["'${TLS_CRT}'"],"sslCert":"'${PEM}'","sslKey":"'${KEY}'"}'
You might want to do this, for example, if you're backing Rocket.Chat with a TLS-secured Mongo replica set and need to pass certificates/PEM files, etc. to connect to it.
If you see the following error during startup:
MongoTimeoutError: Server selection timed out after 10000 ms
You can try increasing server selection time adding the following property to
MONGO_OPTIONS to change the default value of 10000 to 20000:MONGO_OPTIONS='{ "serverSelectionTimeoutMS": 20000 }'
