A bash script that takes an argument that uses it in a docker bash command?

Question

So say I have a bash script that takes two arguments.

./myBash.sh 123 "123123"

Cool we can do something like

index=$1 
location=$2

How do I use those arguments in a docker command within myBash.sh

like:

docker exec myDockerContainer_1 bash -c 'myMigrationScript --pw=$location  --pwOld=1234 --indexToStartAt=$index'

But this doesn't seem to work? The variables do not get carried over inside the docker container?

its probably because you are using single quote `'`, you need to use double quotes `"` — user5359531, Dec 01 '22 at 16:29

If you set this in your Dockerfile

ENTRYPOINT ["bash", "-c"]
CMD ["/path/to/myBash.sh"]

Then you only need

docker run --rm image arg1 arg2
