To assign additional directories on the host as external storage, add the following to the docker run command line when starting a software event broker: -v : Shared drives are configured in the Docker Settings menu. To expand the default storage capability of software event broker containers in Docker for Windows, you can make use of drives from the host, but these drives must be shared with the Docker for Windows Linux VM. In this example, all the storage-elements have been re-assigned, but you can delete lines in accordance with your own plan.

Update the docker create command using the -volume option to assign the storage-elements to the volumes you've created.

For detailed instructions, refer to Volumes in the Docker documentation.

Since the specific steps for performing this task vary from one environment to the next, we recommend that you consult your environment’s documentation for instructions. To assign storage-elements to dedicated external volumes, do the following:

Some examples for how to assign external storage with Docker are shown below. Use External Storage Devices in Productionįor production deployments, we recommend that you assign the event broker's storage-elements to external storage devices.įor information about storage options for Kubernetes, see Storage in the Kubernetes documentation.įor information about storage options for OpenShift, see Understanding Persistent Storage in the OpenShift documentation. We recommend using volumes as the means to persist data for a software event broker container.įor storage-elements mounted as volumes, we recommend xfs as the filesystem, because it has better performance than ext4. For information about getting the best storage performance, consult the best practices documentation for your platform.Īs mentioned above, a volume is storage on the host filesystem that has been mounted on the container's filesystem outside the writable layer.

The software event broker requires storage with medium to high bandwidth/IOPs and low latency. We strongly recommended allocating storage outside the union filesystem for all storage-elements.

This can cause the container to run out of space in the union filesystem and prevent data from being properly migrated during upgrade. If you leave the storage-elements unspecified when you start the container, they will be stored in the container's writable layer. The container image has predefined mount points for an event broker's storage-elements. Support is provided for any storage-driver- overlay2 is a good choice. There are two options for containers to store files in the host machine so that the files are persisted even after the container stops: volumes and bind mounts.įor more information about storage options for containers, see Manage Data in Docker in the Docker documentation. This extra abstraction reduces performance as compared to using data volumes, which write directly to the host filesystem.

The storage driver provides a union filesystem, using the Linux kernel.

Writing into a container's writable layer requires a storage driver to manage the filesystem.

You can't easily move the data somewhere else.

A container's writable layer is tightly coupled to the host machine where the container is running.

The data doesn't persist when that container no longer exists, and it can be difficult to get the data out of the container if another process needs it.

Important: The default on Docker for Mac and Docker for Windows is 2 GB for the Moby VM, so you will need to change it to 4 GB.By default all files created inside a container are stored on a writable container layer.

Docker Engine 1.8+ on any supported Linux distribution or Docker for Mac/Windows.
