HTTPConnectionPool(host='localhost', port=8081):This will not work because inside the container of the second docker compose "fileserver" is not defined
CLEARML_FILES_HOST=" "
You have two options:
configure to the docker compose to use the networkhost on all conrtainers (as oppsed to the isolated mode they are now running ing)2. Configure all of the CLEARML_* to point to the Host IP address (e.g. 192.168.1.55) , then rerun the entire thing.
