- Step 2: Start the container

  ```console
  $ docker run -d busybox --name testlog top
  ```

- Step 3: Read the container logs

  ```console
  $ docker logs 7d6ac83a89a0

### Configuration options

The dual logging cache accepts the same configuration options as the
[`local` logging driver](drivers/local.md), but with a `cache-` prefix. These options
can be specified per container, and defaults for new containers can be set using
the [daemon configuration file](/reference/cli/dockerd/#daemon-configuration-file).

By default, the cache has log-file rotation enabled, and is limited to a maximum
of 5 files of 20MB each (before compression) per container. Use the configuration
options described below to customize these defaults.

| Option           | Default   | Description                                                                                                                                       |
| :--------------- | :-------- | :------------------------------------------------------------------------------------------------------------------------------------------------ |
| `cache-disabled` | `"false"` | Disable local caching. Boolean value passed as a string (`true`, `1`, `0`, or `false`).                                                           |
Title: Dual Logging Configuration and Driver Compatibility
Summary
This section details how dual logging works in Docker, highlighting that it doesn't affect drivers like `local`, `json-file`, and `journald` which natively support reading logs. It explains that the dual logging cache accepts the same configuration options as the `local` logging driver, with a `cache-` prefix, and that by default log rotation is enabled, limiting the cache to 5 files of 20MB each. It also describes the `cache-disabled` option, which allows disabling the local cache using a boolean value.
