[jira] [Closed] (FLINK-14812) Add custom libs to Flink classpath with an environment variable.

["Chesnay Schepler (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-14812?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chesnay Schepler closed FLINK-14812.
------------------------------------
    Resolution: Fixed

This is only really relevant for cases like docker/kubernetes where it is not easy to access to local filesystem to copy jars around.

> 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
