Environment Variables

Certain parts of the engine are configured before reading the application configuration file, and therefore are set via environment variables.

Engine level

com.kubling.maxStringLength

By default, the string data type has a limit of 4,000 characters. However, you can increase this limit by setting the desired value in this environment variable.

Application level

APP_CONFIG

The path to the application configuration YAML file.

ENABLE_WEB_CONSOLE

Specifies whether the web console endpoint is activated. This also enables the restart endpoint.

SCRIPT_LOG_LEVEL

Specifies the log level for messages from scripts to be printed.

MAX_HTTP_THREAD_POOL_SIZE

Specifies the maximum number of threads in the HTTP thread pool.

MAX_HTTP_WAITING_QUEUE_CAPACITY

Specifies the maximum capacity of the waiting queue for HTTP requests.

KBL_SKIP_ENV_VAR_TEMP_FILE_ENCRYPTION

Indicates whether the encryption of environment variables saved to disk (used for restarting the engine) should be skipped. When encryption is not skipped, and the container is stopped and restarted, the random key manager generates a new key. This new key cannot decrypt the file created during the previous run, causing issues with the restart process.

INST_AZ_MON_ACTIVE and INST_AZ_MON_KEY DEPRECATED Marked for removal

Variables related to Azure monitoring, enabling the feature and providing the necessary key.
