Description

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, e.g.:

config.providers=env
{{}}

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

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