Hi Guowei,

thanks for your reply! This information was still missing. The presenter mentioned the documentation but I hadn't found it. So your link to the specific place is valuable too.

Hi,
I do not try it. But from the documentation[1] it seems that you might need add the "jobmanager.rpc.address: jobmanager" to the FLINK_PROPERTIES before creating a network.

Best,

    Hi,

    I'm trying to start a mini cluster following the explanations
    given in a
    flink forward presentation [1]

    Starting a jobmanager task is possible

    FLINK_PROPERTIES="jobmanager.memory.process.size: 2048m
    parallelism.default: 4
    "
    docker network create flink-network

    docker run  \
    --rm   \
    --name=jobmanager  \
    --network flink-network \
    -p 8081:8081  \
    --env FLINK_PROPERTIES="${FLINK_PROPERTIES}"  \
    flink:1.13.0-scala_2.12-java11 jobmanager


    Unfortunately the taskmanager process can't connect

    docker run  \
    --rm   \
    --name=taskmanager  \
    --network flink-network \
    --env FLINK_PROPERTIES="${FLINK_PROPERTIES}"  \
    flink:1.13.0-scala_2.12-java11 taskmanager

    and the dashboard (of the jobmanager task) doesn't show the
    taskmanager
    process (as I would expect)

    Any hints? - Thanks!

    Günter
