logger error of flink 1.8+ docker mode

[Ever <43...@qq.com>]

After deploying Flink 1.8.0 with docker,  logger page for jobManager and taskManager doesn't work.





I try to run flink with background mode instead of start-foreground(docker-entrypoint.sh) , but  the container can't be started.


Anyone can help?

Thanks.


I modify the docker-entrypoint.sh and it works.
Here's what I updated:


#exec $(drop_privs_cmd) "$FLINK_HOME/bin/jobmanager.sh" start-foreground"$@"
$FLINK_HOME/bin/jobmanager.sh start "$@"

#exec $(drop_privs_cmd) "$FLINK_HOME/bin/taskmanager.sh" start-foreground "$@"
 $FLINK_HOME/bin/taskmanager.sh start "$@"



#hold the container
tail -f $CONF_FILE

Hi Ever,

May you share more information about your environment? 
If you could not find any log in the flink dashboard, you need to check the log4j of job manager and task manager. Make sure you could find the log files(jobmanager.log/taskmanager.log) under /opt/flink/log in the docker container.


If you are running flink with background mode, you need to specify a daemon process instead. Otherwise, the docker container will finish soon.
