Dear all, I followed the instructions found here: https://ci.apache.org/projects/flink/flink-docs-release-1.7/ops/deployment/kubernetes.html Minikube version 0.31-01 Kubernetes version 1.10 Flink Docker image: flink:latest (1.7.0-scala_2.12)
I ran the following commands: minikube start minikube ssh 'sudo ip link set docker0 promisc on' kubectl create -f jobmanager-deployment.yaml kubectl create -f taskmanager-deployment.yaml kubectl create -f jobmanager-service.yaml The 2 taskmanagers fail. Output: Starting Task Manager config file: jobmanager.rpc.address: flink-jobmanager jobmanager.rpc.port: 6123 jobmanager.heap.size: 1024m taskmanager.heap.size: 1024m taskmanager.numberOfTaskSlots: 2 parallelism.default: 1 rest.port: 8081 blob.server.port: 6124 query.server.port: 6125 Starting taskexecutor as a console application on host flink-taskmanager-7679c9d55d-n2trk. 2018-12-19 11:42:45,216 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -------------------------------------------------------------------------------- 2018-12-19 11:42:45,218 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - Starting TaskManager (Version: 1.7.0, Rev:49da9f9, Date:28.11.2018 @ 17:59:06 UTC) 2018-12-19 11:42:45,218 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - OS current user: flink 2018-12-19 11:42:45,219 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - *Current Hadoop/Kerberos user: <no hadoop dependency found>* 2018-12-19 11:42:45,219 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - JVM: OpenJDK 64-Bit Server VM - Oracle Corporation - 1.8/25.181-b13 2018-12-19 11:42:45,219 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - Maximum heap size: 922 MiBytes 2018-12-19 11:42:45,220 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - JAVA_HOME: /docker-java-home/jre 2018-12-19 11:42:45,220 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - No Hadoop Dependency available 2018-12-19 11:42:45,221 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - JVM Options: 2018-12-19 11:42:45,221 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -XX:+UseG1GC 2018-12-19 11:42:45,221 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -Xms922M 2018-12-19 11:42:45,221 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -Xmx922M 2018-12-19 11:42:45,221 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -XX:MaxDirectMemorySize=8388607T 2018-12-19 11:42:45,223 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -Dlog4j.configuration=file:/opt/flink/conf/log4j-console.properties 2018-12-19 11:42:45,223 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -Dlogback.configurationFile=file:/opt/flink/conf/logback-console.xml 2018-12-19 11:42:45,223 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - Program Arguments: 2018-12-19 11:42:45,223 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - --configDir 2018-12-19 11:42:45,224 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - /opt/flink/conf 2018-12-19 11:42:45,224 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - Classpath: /opt/flink/lib/flink-python_2.12-1.7.0.jar:/opt/flink/lib/log4j-1.2.17.jar:/opt/flink/lib/slf4j-log4j12-1.7.15.jar:/opt/flink/lib/flink-dist_2.12-1.7.0.jar::: 2018-12-19 11:42:45,224 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - -------------------------------------------------------------------------------- 2018-12-19 11:42:45,228 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - Registered UNIX signal handlers for [TERM, HUP, INT] 2018-12-19 11:42:45,233 INFO org.apache.flink.runtime.taskexecutor.TaskManagerRunner - Maximum number of open file descriptors is 1048576. 2018-12-19 11:42:45,249 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: jobmanager.rpc.address, flink-jobmanager 2018-12-19 11:42:45,250 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: jobmanager.rpc.port, 6123 2018-12-19 11:42:45,251 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: jobmanager.heap.size, 1024m 2018-12-19 11:42:45,251 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: taskmanager.heap.size, 1024m 2018-12-19 11:42:45,251 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: taskmanager.numberOfTaskSlots, 2 2018-12-19 11:42:45,252 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: parallelism.default, 1 2018-12-19 11:42:45,252 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: rest.port, 8081 2018-12-19 11:42:45,254 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: blob.server.port, 6124 2018-12-19 11:42:45,254 INFO org.apache.flink.configuration.GlobalConfiguration - Loading configuration property: query.server.port, 6125 *2018-12-19 11:42:45,261 INFO org.apache.flink.core.fs.FileSystem - Hadoop is not in the classpath/dependencies.
