Managing the configuration
Manage DataStax Distribution of Apache Cassandra™ (DDAC) configuration using a mounted volume or environment variables.
Manage the DataStax Distribution of Apache Cassandra™ (DDAC) configuration using one of the following options:
- Environment variables to change the configuration at runtime.
- Docker file or directory volume mounts.
- Docker overlay file system.
Note: DSE and DDAC use 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.
