------------------------------------

             Summary: Initialization of Testcontainers unstable on Azure
                 Key: FLINK-22971
                 URL: https://issues.apache.org/jira/browse/FLINK-22971
             Project: Flink
          Issue Type: Bug
          Components: Tests
            Reporter: Xintong Song


The following properties can be observed in many high-frequency test instabilities. They are likely sharing a common root cause.
* Use the Testcontainers framework
* Fail due to no outputs in long time
* A stack similar to the following can be find in the thread dump.
** Thread is RUNNABLE
** Testcontainers DockerClient is being created: {{org.testcontainers.DockerClientFactory.client(DockerClientFactory.java:205)}}
** Seems to be downloading something via okhttp
