[~Jamalarm] I know your work.
For now, that looks pretty good.
It looks very helpful for me.
Thanks!
> Add custom libs to Flink classpath with an environment variable.

> Key: FLINK-14812
> URL: https://issues.apache.org/jira/browse/FLINK-14812
> Project: Flink
> Issue Type: New Feature
> Components: Deployment / Kubernetes, Deployment / Scripts
> Reporter: Eui Heo
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h

> To use plugin library you need to add it to the flink classpath. The
> documentation explains to put the jar file in the lib path.
> https://ci.apache.org/projects/flink/flink-docs-stable/monitoring/metrics.html#prometheus-orgapacheflinkmetricsprometheusprometheusreporter
> However, to deploy metric-enabled Flinks on a kubernetes cluster, we have the
> burden of creating and managing another container image. It would be more
> efficient to add the classpath using environment variables inside the
> constructFlinkClassPath function in the config.sh file.
> In particular, it seems inconvenient for me to create separate images to use
> the jars, even though the /opt/ flink/opt of the stock image already contains
> them.
> For example, there are metrics libs and file system libs:
> flink-azure-fs-hadoop-1.9.1.jar
> flink-s3-fs-hadoop-1.9.1.jar
> flink-metrics-prometheus-1.9.1.jar
> flink-metrics-influxdb-1.9.1.jar
