从 shell 到 docker 容器执行多个命令

Question

I am trying to do in one command, do a bash from docker container, open mongo and make a request with something like

'db.test.find({});'

I am reading from others similar post without success.

This is the command that I am executing.

docker exec -it mongoDB bash -c 'mongo ; use test; db.test.find({})'

And that command give me that

bash: -c: line 0: syntax error near unexpected token {}'

bash: -c: line 0:mongo ; use test; db.test.find({})'

It is that possible?

I hope that you can help me.

Roth.

Answer 1

This is actually possibla using a file to execute multiple commands. Put your mongo script into a file.

Example:

myFile.js

File content:

use myDB
show collections

Then you can execute this file with

mongo < myFile.js

In your situation:

docker exec -it mongoDB bash -c 'mongo < myFile.js'

Don't forget to copy this file into your docker container.

Answer 2

You don't really need to copy the script into the container.

You can simply run :

docker exec -it mongoDB bash -c 'mongo' < myFile.js
