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

from dagster import asset, op, job, get_dagster_logger
from datetime import datetime

@asset
def date():
    return str(datetime.now())


@op
def print_asset(date):
    get_dagster_logger().info(f'{date}')


@job
def job_test_asset():
    print_asset(date.to_source_asset())

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!
