 ## Docker Image
 
-AxonIQ provides a ready to use [Axon Server image](https://hub.docker.com/r/axoniq/axonserver) **for development and trial purposes**. There are two images available: one with Axon Server running as the user "`root`" and one with Axon Server running as user "`axonserver`". Both images are based on "debug" images from [Google's Distroless series](https://github.com/GoogleContainerTools/distroless), which means they include a (limited) shell that allows you to connect "into" the running image and perform some commands. Naturally you should not use these for production because of this, but they are perfect for development and test environments.

-* The "`root`" image of version 2023.1 is available as "`axoniq/axonserver:2023.1-dev`" and is based on "`gcr.io/distroless/java:11-debug`". This image is particularly useful for running in Docker Desktop, as it will not have any trouble creating files and directories as user "`root`".
-* The "`axonserver`" image of version 2023.1 is available as "`axoniq/axonserver:2023.1-dev-nonroot`" and is based on "`gcr.io/distroless/java:11-debug-nonroot`". This image is more secure and useful in Kubernetes and OpenShift clusters. You should take care to declare the user- and group-id, both of which are `1001` and are named "`axonserver`". Doing this will ensure that any mounted volumes will be writable by the user running Axon Server.

+> Up to release 2023.2.0 the default Axon Server image (axoniq/axonserver:latest) was using Axon Server Standard Edition version 4.6.11. There is a difference in the directory structure between version 4.6.11 and the current version. One change is that the working directory has changed from `/` to `/axonserver`. All files and directories created by Axon Server are stored in this directory (or subdirectories).
