I didn't really understand the question, I will describe the situation in stages
1 I deployed dagster with several containers as described in the documentation, 4 containers rose
2 next, I wrote a simple code based on the example from the documentation that I sent above
3 materialized the asset through the web interface
4 I tried to output the contents in the logs, to which I received an error, the file was not found
5 I started these processes again, climbed inside the container via docker exec bash, looked at the file system and saw that the result of materialization was saved in the local container
I read a little about io_manager and didn't really understand how to configure saving and reading data
Thanks!
