Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

So far it is not possible to inject additional configurations stored in environment variables. This topic came up in several projects and would be a useful feature to have as a Kafka config feature similar to file/directory providers, example configuration:

config.providers=env

config.providers.env.class=org.apache.kafka.common.config.provider.EnvVarConfigProvider

ssl.key.password=${env:<...>:KEY_PASSPHRASE}

Public Interfaces

A new implementation of the interface org.apache.kafka.common.config.provider.ConfigProvider will be added.
