Create a MinIO service using `docker service` to read from Docker secrets.

```
docker service create --name="minio-service" --secret="access_key" --secret="secret_key" quay.io/minio/minio server /data
```

docker run --rm --net=mint_default \
	--name="mint-${MODE}-${JOB_NAME}" \
	-e SERVER_ENDPOINT="nginx:9000" \
	-e ACCESS_KEY="${ACCESS_KEY}" \
	-e SECRET_KEY="${SECRET_KEY}" \
	-e ENABLE_HTTPS=0 \
	-e MINT_MODE="${MINT_MODE}" \
