Attila Mészáros updated FLINK-38285:
------------------------------------
Summary: Allow to override config options with environment variables (was:
Allow to overrride config options with environment variables)
> Allow to override config options with environment variables
> -----------------------------------------------------------
>
> Key: FLINK-38285
> URL: https://issues.apache.org/jira/browse/FLINK-38285
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Reporter: Attila Mészáros
> Assignee: Attila Mészáros
> Priority: Major
>
> Overriding or setting config options using environment variables would make
> the operator more Kubernetes native since it is a common practice to have
> settings propagated as env var (for Deployment object) in Kubernetes. Would
> also help to override settings when running operator locally.
>
> The only issue is how to encode flink config options as env vars, what I
> propose is for names:
> * dot would be replaced by by underscore: "." -> "_"
> * - hypen by replaced by double underscore: "-" -> "__"
> * to upper case
> * prefixed by "FLINK_CONF_"
> Thus "restart-strategy.failure-rate.delay" =>
> "FLINK_CONF_RESTART_{_}STRATEGY_FAILURE{_}__RATE_DELAY"
> (Complex values are not an issue, can be simply in quotes like "1 m". )
>
