Bonjour :wave:

My task:

- name: "MongoDB Operate | Create user - {{ mongo_metrics_exporter_user }}"
  community.docker.docker_container_exec:
    container: "{{ app_name }}-{{ allocation_id.stdout }}"
    command: "mongosh admin -u {{ mongo_root_username }} -p {{ mongo_root_password }} < metrics_exporter_user.js"
    chdir: "/data/db"

Result:

But when I’m connected to container:

root@f17f90a1de26:~# stat /data/db/metrics_exporter_user.js

And if I try:

cd /data/db

mongosh admin -u <user> -p <password> metrics_exporter_user.js

It works!

Has anyone had this problem before? And solution? :sweat_smile:

Thanks!

Some of the output doesn’t seem to be consistent with your task. Sometimes the < is there, sometimes it is not. I’m assuming it is present in command.

The module doesn’t pass the command to a shell, but direclty executes it. The mongosh command is executed with the following parameter list:

  1. admin
  2. -u
  3. <user>
  4. -p
  5. <password>
  6. <
  7. metrics_expoerter_user.js

Now mongosh tries to open the file <, which doesn’t exist.

If you wrap the command as the argument of /bin/sh -c "put command here" then it should work.

Thanks a lot! :partying_face:
