 1. Create a Docker Compose file to run both containers, being sure that they use the same network interface\. This is necessary because the Secrets Manager Agent does not accept requests from outside the localhost interface\. The following example shows a Docker Compose file where the `network_mode` key attaches the `secrets-manager-agent` container to the network namespace of the `client-application` container, which allows them to share the same network interface\.
