Hello,

I’m doing a fresh 3.4 installation of the mender-server using docker compose method.

At step Deployments service ([Installation with Docker Compose | Mender documentation](https://docs.mender.io/3.4/server-installation/installation-with-docker-compose#deployments-service)), the tutorial indicates the `DEPLOYMENTS_AWS_URI` key need to be updated and the following command is provided to do so:

> sed -i.bak “s/https://set-my-alias-here.com/https://$STORAGE\_PROXY\_DOMAIN\_NAME/g” config/prod.yml

Instead, the git diff indicates the `DEPLOYMENTS_AWS_EXTERNAL_URI` has been updated (due to the yml template and above sed command). `DEPLOYMENTS_AWS_URI` is still `http://minio:9000`.

=\> Which part of this is wrong? Can you clarify what should be done and which key should be updated please and how? Is the tutorial wrong or is the yml template wrong ?

Regards,  
Joel

Hello! 👋

This seems to be an outdated snippet output in the documentation. Having `DEPLOYMENTS_AWS_URI` set to `http://minio` will make the server use the internal docker network to communicate with the minio storage backend, but all public signed URLs sent to devices will use the hostname and scheme from `DEPLOYMENTS_AWS_EXTERNAL_URI` so your configuration seems to be correct.

BR,
