Docker known issues
The following issues are recognized.
The Cassandra File System (CFS) is not supported.
Lifecycle Manager (LCM) is not supported.
Changing any file not included in the list of approved configuration files will require an additional host volume or customization of the image. An example is SSL key management.
The JVM heap size must be set for DataStax Enterprise (DSE) running inside the container using the
JVM_EXTRA_OPTSvariable or custom cassandra-env.sh. If not set, Java does not honor resource limits set for the container, and will peer through the container to use resources (memory and CPU) of the host. See the
JVM_EXTRA_OPTSvariable in Using environment variables for more information.
