mongo:latest image is missing mongo binary

[bernermic]

Hi,

as of today we face an issue with the mongo command.

Steps to reproduce:

• Start a mongodb:
  • docker run -it --rm --name mongo mongo:latest mongod
• Execute command mongo in the started mongodb
  • docker exec -it mongo mongo
    This delivers the following error:
    OCI runtime exec failed: exec failed: unable to start container process: exec: "mongo": executable file not found in $PATH: unknown

With version 5.0 the mongo command is working as expected.

Expected

mongo command is still working

Further info

We use a project called testcontainers which starts a mongo:latest and connects with command mongo. This fails with the explained behaviour.
Related to this: testcontainers/testcontainers-java#5768

Best

mongo is literally gone now

You can use mongosh instead

$ docker run -d --name mongo mongo:6

$ docker exec -it mongo mongosh

To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy).
You can opt-out by running the disableTelemetry() command.

   Enable MongoDB's free cloud-based monitoring service, which will then receive and display
   metrics about your deployment (disk utilization, CPU, operation statistics, etc).

   The monitoring data will be available on a MongoDB website with a unique URL accessible to you
   and anyone you share the URL with. MongoDB may use this information to make product
   improvements and to suggest MongoDB products and deployment options to you.

   To enable free monitoring, run the following command: db.enableFreeMonitoring()
   To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

If it is gone then should the docker-entrypoint.sh scripts be updated? Currently they have this line:

mongo/5.0/docker-entrypoint.sh

Line 199 in b149de1

mongo --norc --nodb --quiet --eval "load('/js-yaml.js'); printjson(jsyaml.load(cat($(_js_escape "$configPath"))))" > "$jsonConfigFile"

Which shows up in my docker logs as /usr/local/bin/docker-entrypoint.sh: line 199: mongo: command not found

Testing a fix since mongosh doesn't have all the same available javascript functions as mongo did.

is the mongo binary going away?

[tianon]

From MongoDB upstream's perspective, it's been "going away" since they introduced mongosh, and in 6.0, it's "gone" 😬 ❤️

I'm following some old videos on docker and this error really bothered me. Finally I got to interact with mongodb shell. Leaving a comment just to say thank you :)

[aogilvie]

Does anyone know the earliest compatibility of mongoDB for which we can use mongosh?

Nothing is mentioned in the official docs - https://www.mongodb.com/docs/mongodb-shell/
Or the repository - https://github.com/mongodb-js/mongosh

Looks like 5.0 is the first to have mongosh.

https://github.com/mongodb-js/mongosh/blob/9cf53bc336c79e505cf034bf5e6f3b3b3796cf25/package.json#LL125C6-L125C6 specifies version 5.1.0 of the mongodb Node.js library (https://www.npmjs.com/package/mongodb), which is probably what determines the underlying compatibility level (but realistically, you'll probably just have to run some tests to figure out what the lower limit really is in practice).

@ale900522 You are using an older version which doesn’t have mongosh.
You can use mongo instead.
