Docker known issues

List of current known issues.

The following issues are recognized.

  • Cassandra File System (CFS) is not supported.
  • Docker for DDAC does not support DataStax Studio or DSE OpsCenter.
  • 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_OPTS variable 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 Tuning Java resources in the DDAC documentation and see the JVM_EXTRA_OPTS variable in Using environment variables for more information.
