[jira] [Comment Edited] (ZOOKEEPER-4238) NullPointerException in
ContainerManager is still a thing
[ https://issues.apache.org/jira/browse/ZOOKEEPER-4238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17438464#comment-17438464 ]

facing the same problem, but I think the reason is the entrypoint.sh of zk docker images did not parse the ZOO_PORT parameter, so the zoo.cfg will not have a clientPort to start. I changed the compose.yaml and it works for me now.
