1. 此步骤(k8s)部署才需要 配置文件

先把Flink的所有配置文件拷贝到本地, 再把本地的配置文件挂在到POD里面

1.1 jobmanager的配置文件

vim flink-conf.yaml 修改配置文件

jobmanager.rpc.address: flink-jobmanager-svc
jobmanager.rpc.port: 6123
jobmanager.heap.size: 1024m
taskmanager.heap.size: 1024m
taskmanager.numberOfTaskSlots: 1
parallelism.default: 1
high-availability: zookeeper
high-availability.zookeeper.path.root: /flink
high-availability.cluster-id: 1
high-availability.storageDir: file:///data/ha
high-availability.zookeeper.quorum: localhost:2181
zookeeper.sasl.disable: true
high-availability.jobmanager.port: 6123
state.backend: filesystem
state.backend.fs.checkpointdir: file:///data/state
web.upload.dir: /data/upload
blob.server.port: 6124
metrics.internal.query-service.port: 6125
classloader.resolve-order: parent-first

vim zoo.cfg //可高用的配置

# The number of milliseconds of each tick
tickTime=2000

# The number of ticks that the initial  synchronization phase can take
initLimit=10

# The number of ticks that can pass between  sending a request and getting an acknowledgement
syncLimit=5

# The directory where the snapshot is stored.
# dataDir=/tmp/zookeeper

# The port at which the clients will connect
clientPort=2181

# ZooKeeper quorum peers
server.1=localhost:2888:3888
dataDir=/usr/local/flink-1.8.1/zookeeper/data
dataLogDir=/usr/local/flink-1.8.1/zookeeper/log

1.2 taskmanager的配置文件

vim flink-conf.yaml

jobmanager.rpc.address: flink-jobmanager-svc
jobmanager.rpc.port: 6123
jobmanager.heap.size: 1024m
taskmanager.heap.size: 1024m
taskmanager.numberOfTaskSlots: 4
parallelism.default: 1
high-availability: zookeeper
high-availability.cluster-id: 1
high-availability.storageDir: file:///tmp
high-availability.zookeeper.quorum: flink-jobmanager-svc:2181
zookeeper.sasl.disable: true
classloader.resolve-order: parent-first

kubectl apply -f flink-jobmanager.yml flink-taskmanager.yml //创建配置文件 运行项目 打开 IP:30044 查看是不是正常

注意事项: jobmanager和taskmanager lib的jar 要保持一致
