How to execute mongodb commands inside the bash script

Question

I'm trying to run mongo commands through my bash script file.

I have sample.sh -- run with ./sample.sh

I want to run below command inside my sample.sh file. It is bash script. I want to mongo commands run inside the file, not inside the shell.

kubectl exec $mongoPodName -c mongo-mongodb -- mongo db.createUser({user:"admin",pwd:"123456",roles:[{role:"root",db:"admin"}]})

I get the error below :

./generate-service-dbs.sh: line 37: syntax error near unexpected token `('
./generate-service-dbs.sh: line 37: `kubectl exec $mongoPodName -c mongo-mongodb -- mongo db.createUser({user:"admin",pwd:"123456",roles:[{role:"root",db:"admin"}]})'

Don't you have to run command with --eval?

kubectl exec $mongoPodName -c mongo-mongodb -- mongo --eval 'db.createUser({user:"admin",pwd:"123456",roles:[{role:"root",db:"admin"}]})'

I try --eval for this command ``` kubectl exec $mongoPodName -c mongo-mongodb -- mongo --eval 'use myTest' ``` . It has error : ``` 2020-08-18T22:31:53.745+0000 E QUERY [js] uncaught exception: SyntaxError: unexpected token: identifier : @(shell eval):1:4 ```

I need to create mongodbs with user and roles from *.ini files, so i should run multi-line mongo commands within my sample.sh file, but i have many errors.

I am afraid I am not too familiar with mongodb but you should able to run a few command in a .js file. Please see this reference : docs.mongodb.com/manual/reference/program/mongo/…

We need to use double quotes (") instead of single quotes here. I tested with both cases, and the one which works is with single quotes.

kubectl exec $mongoPodName -c mongo-mongodb -- mongo --eval "db.createUser({user:\"admin\",pwd:\"123456\",roles:[{role:\"root\",db:\"admin\"}]});"
