I want to run the docker image with the custom configuration . currently i am adjusting by changing the CMD entry to this so that i can use the below dbpath in dockerfile  
CMD [“mongod”, “–dbpath”, “/var/lib/mongod”]

Hi @favas

Could you upload the used configuration file?

I have the same problem on a Docker image of PSMDB version 4.4.5-7 and did a little investigation. The error is thrown by “jq”.

There is a problem with this line in entrypoint.sh when a custom mongodb.conf is passed in:

> mongo --norc --nodb --quiet --eval “load(‘/js-yaml.js’); printjson(jsyaml.load(cat($(\_js\_escape “$configPath”))))” \> “$jsonConfigFile”

js.yaml cannot be loaded. If you open up $jsonConfigFile, you will see the following:

> {“t”:{“$date”:“2021-08-12T09:27:59.080Z”},“s”:“E”, “c”:“-”, “id”:22779, “ctx”:“js”,“msg”:“file [{filename}] doesn’t exist”,“attr”:{“filename”:“/js-yaml.js”}}  
> Error: error loading js file: /js-yaml.js :  
> @(shell eval):1:1  
> exiting with code -4

The $jsonConfigFile is subsequently used below in this line, thus it generates the same error again:

> elif \_parse\_config “$@” && jq --exit-status ‘.net.bindIp // .net.bindIpAll’ “$jsonConfigFile” \> /dev/null; then

Is there any chance of fixing this problem soon?
