Configuring

Configuration using one of the following options:

Recommended settings as the default starting point.
Environment variables to change the configuration at runtime.
Exposing public ports
The DSE configuration volume to get configuration files from a mounted host directory without replacing or customizing configuration file in the container.
Data volumes can also be mounted, so that data can be persisted beyond the lifetime of a container.

DSE uses the default values defined for the environment variables unless explicitly set at runtime. Custom configuration files override the default or explicitly set environment variables.

DataStax uses a common base image for all products. To customize the operating system or install additional packages, modify the base/Dockerfile. The DataStax base images use OpenJDK due to the end of public updates for Oracle JDK. All DataStax repositories on Docker Hub include OpenJDK.
