Using variable in puppet exec command?

Question

Hello Iam new to puppet and now trying to explore with puppet manifests. Actually Iam creating a manifest for mongodb and I want to use a variable inside the exec. But each time it is giving me error. My mongodb.pp is as below

    class db::mongodb ($interface) {
    $ip = inline_template("<%= scope.lookupvar('::ipaddress_${interface}') -%>") 
exec {'/bin/bash -c "mongo --host $ip --eval \'  db = db.getSiblingDB("test"); db.addUser({user: "test", pwd: "test", roles: [ "readWrite", "dbAdmin" ]})\'"' :
}
}

But while running this Iam getting error like below

could not connect to the server --eval:27017 at src/mongo/shell/mongo.js:147

IP part is missing in the error because $ip is not substituting IP in the mongo command.. I tried different ways but all gives the same error. Actually I want to know how to use variable in the exec command as above in the puppet?? Any help is much appreciated.

Variables are only interpolated in double-quoted strings (""), not single-quoted strings ('') and should be in the form ${ip} when inside a string (documentation, via visual index).

You also have quite a few quotes there, so removing the bash -c wrapper would simplify it by removing one set:

exec { "mongo --host ${ip} --eval '  db = db.getSiblingDB(\"test\"); db.addUser({user: \"test\", pwd: \"test\", roles: [ \"readWrite\", \"dbAdmin\" ]})'" :
}

If the bash shell is necessary, use provider => shell instead.

Thanks.. giving 'provider => shell' solves the issue .. But why bin/bash with same command as above is not working??
