如何将卷安装在由另一个Docker容器创建的Docker容器上？

Question

I have a containerized REST API server using docker. I have mounted a folder on my host machine to this rest container using docker flag
--mount type=bind, source=<path/on/hostmachine>, target=<path/on/container>

This works perfectly and I can see real time mapping of files between my host and rest container. Now, my rest container generates a yaml file that contains the configuration for the new container that comes up and writes this configuration file to the shared volume mount.

I want to mount the same <path/on/hostmachine> that contains the configuration files generated by the rest container to the new container that comes up. The issue is, I do not bring the container up using the cli.

This is why I cannot use the --mount flag. I tried multiple ways to try doing it through the yaml file.

Blockquote - Using absolute path as
volumes: - <absolute/path/on/hostmachine>:<path/on/new/container>

did not work.

Blockquote - Using volumes with type defined as
volumes: - type: bind source:<absolute/path/on/hostmachine> target:<path/on/new/container>

did not work and gave volumes should be string error

How do I mount the same home directory to the new container that comes up on the rest container?

I figured out the issue in the first approach. I was using my path as "./Users/username/Desktop" instead of "/Users/username/Desktop" which was causing the path mismatch. I misunderstood the lack of errors. Rookie Mistake, Mea Culpa.
