运行一条命令就可以在k8s集群搭建起flink的弹性集群，这就是flink native Kubernetes integration
./bin/flink run-application
--target kubernetes-application
-Dkubernetes.cluster-id=first-application-cluster
-Dkubernetes.container.image=docker-dev/job:4.1.0-202107011136-e2e38
-Dkubernetes.container.image.pull-secrets=arm-repo-secret
-Dkubernetes.rest-service.exposed.type=NodePort
-Dkubernetes.pod-template-file.jobmanager=./job-template.yaml
-Dhigh-availability=org.apache.flink.kubernetes.highavailability.KubernetesHaServicesFactory
-Dhigh-availability.storageDir=file:///tmp/flink
-Dclassloader.resolve-order=parent-first
-c com.ericsson.cv.reactor.job.ReactorJobApplication
local:///opt/flink/usrlib/job-4.1.0-202107011136-e2e38-with-dependency.jar --config.path "/opt/flink/usrconf/config.properties" --dispatcher.config.path "/opt/flink/usrconf/dispatcher-config.json"
下面是运行上面命令时的一些准备工作。
down flink
我们要运行flink的命令，所以要先下载好flink的发行包，flink-13.0以后的版本，下载好后解压。
K8s环境
要准备好k8s的环境，即运行flink命令行的机器要可以执行kuebctl，并且有权限创建pod等资源。或者有./kube/config也可以。
RBAC
需要pod有权限创建和管理k8s资源，因此需要考虑RBAC。
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
name: fabric8-rbac
subjects:
- kind: ServiceAccount
# Reference to upper's `metadata.name`
name: default
# Reference to upper's `metadata.namespace`
namespace: default
roleRef:
kind: ClusterRole
name: cluster-admin
apiGroup: rbac.authorization.k8s.io
Docker
从私服拉取docker image时要加imagePullSecrets，用下面命令创建好se
kubectl create secret generic arm-repo-secret
--from-file=.dockerconfigjson=/home/eyfnane/.docker/config.json
--type=kubernetes.io/dockerconfigjson
kubectl get secret可以查看到arm-repo-secret被创建好
使用pod-template
- 创建ConfigMap
apiVersion: v1
kind: ConfigMap
metadata:
name: flink-config
data:
config.properties: |+
source.bootstrap.servers=190.117.146.5:9092
source.auto.offset.reset=latest
sink.bootstrap.servers=190.117.146.5:9092
source.topics=raccoon.reactor.event
source.group.id=raccoon.reactor.event.group_ft
kafka.sink.topic=raccoon.reactor.sink
watermarks.maxOutOfOrderness=1
database.url=jdbc:postgresql://190.120.103.38:5432/job_db
database.user=xxx
database.password=xxx
parallelism.max=64
parallelism.default=1
parallelism.vehicleKeyExtractor=1
parallelism.vehiclePreEnrich=1
parallelism.vehicleEnrich=1
enrichment.vehicle.enabled=false
event.source.type=predefined
checkpoint.enable=true
checkpoint.interval=95000
checkpoint.minPause=500
checkpoint.timeout=60000
checkpoint.maxConcurrent=1
checkpoint.enableExternalized=DELETE_ON_CANCELLATION
sink.silence.period.max=2592000
dispatcher-config.json: |+
{
"connections": [
{
"name": "dispatcher-flink-1",
"type": "dispatcher-flink",
"configs": {
"auto_offset_reset": "earliest",
"kafka_poll_interval_sec": 1
}
}
}
上面内容命名为flink-cm.yaml kubectl apply -f flink-cm.yaml 创建出ConfigMap，创建成功后可以kubectl get cm查看到创建的ConfigMap。
- 创建和编辑jobmanager-pod-template
apiVersion: v1
kind: Pod
metadata:
name: jobmanager-pod-template
spec:
containers:
# Do not change the main container name
- name: flink-main-container
resources:
requests:
ephemeral-storage: 2048Mi
limits:
ephemeral-storage: 2048Mi
volumeMounts:
- name: config-volume
mountPath: /opt/flink/usrconf/config.properties
subPath: config.properties
- name: dispatcher-config-volume
mountPath: /opt/flink/usrconf/dispatcher-config.json
subPath: dispatcher-config.json
volumes:
- name: config-volume
configMap:
name: flink-config
items:
- key: config.properties
path: config.properties
- name: dispatcher-config-volume
configMap:
name: flink-config
items:
- key: dispatcher-config.json
path: dispatcher-config.json
利用之前创建好的名为flink-config的ConfigMap来配置到pod-template中实现把自定义的配置挂载到docker想要的目录下。
上面的准备工作完成后来解释一下这条命令的各个参数
./bin/flink run-application 运行flink命令以application模式
--target kubernetes-application 部署到k8s application模式
-Dkubernetes.cluster-id=first-application-cluster 指定一个群集的id，不能重复
-Dkubernetes.container.image=docker-dev/job:4.1.0-202107011136-e2e38 docker镜像名字
-Dkubernetes.container.image.pull-secrets=arm-repo-secret 从私服拉取要设置secret
-Dkubernetes.rest-service.exposed.type=NodePort 暴露flink-web-ui的方式
-Dkubernetes.pod-template-file.jobmanager=./job-template.yaml 使用pod-template,上面准备的文件
-Dhigh-availability=org.apache.flink.kubernetes.highavailability.KubernetesHaServicesFactory 用k8s做HA
-Dhigh-availability.storageDir=file:///tmp/flink 做HA时要存储的一些信息checkpoint等
-Dclassloader.resolve-order=parent-first kafka的classloader有问题时，显示指定来兼容
-c com.ericsson.cv.reactor.job.ReactorJobApplication 指定启动类，main()方法所在的类
local:///opt/flink/usrlib/job-4.1.0-202107011136-e2e38-with-dependency.jar --config.path "/opt/flink/usrconf/config.properties" --dispatcher.config.path "/opt/flink/usrconf/dispatcher-config.json" 指定自己的jar包，local协议是appliction模式支持的，这个包是在docker里面的jar包，不是本地， 后面是jar的main()方法的agrs参数， --key value --key value 的形式，四个参数组成两个键值被flink的ParameterTool使用。
还有很多参数可以设置如下面。。。
taskmanager.numberOfTaskSlots: 1
high-availability.storageDir: file:///usr/share/reactor/recovery/ft/
state.checkpoints.dir: file:///usr/share/reactor/checkpoints/ft/
state.savepoints.dir: file:///usr/share/reactor/savepoints/ft/
state.backend: rocksdb

方便调试查询列出一些配置
flink - help
$ ./bin/flink -h
./flink <ACTION> [OPTIONS] [ARGUMENTS]
The following actions are available:
Action "run" compiles and runs a program.
Syntax: run [OPTIONS] <jar-file> <arguments>
"run" action options:
-c,--class <classname> Class with the program entry point
("main()" method). Only needed if the
JAR file does not specify the class in
its manifest.
-C,--classpath <url> Adds a URL to each user code
classloader on all nodes in the
cluster. The paths must specify a
protocol (e.g. file://) and be
accessible on all nodes (e.g. by means
of a NFS share). You can use this
option multiple times for specifying
more than one URL. The protocol must
be supported by the {@link
java.net.URLClassLoader}.
-d,--detached If present, runs the job in detached
mode
-n,--allowNonRestoredState Allow to skip savepoint state that
cannot be restored. You need to allow
this if you removed an operator from
your program that was part of the
program when the savepoint was
triggered.
-p,--parallelism <parallelism> The parallelism with which to run the
program. Optional flag to override the
default value specified in the
configuration.
-py,--python <pythonFile> Python script with the program entry
point. The dependent resources can be
configured with the `--pyFiles`
option.
-pyarch,--pyArchives <arg> Add python archive files for job. The
archive files will be extracted to the
working directory of python UDF
worker. Currently only zip-format is
supported. For each archive file, a
target directory be specified. If the
target directory name is specified,
the archive file will be extracted to
a directory with the specified name.
Otherwise, the archive file will be
extracted to a directory with the same
name of the archive file. The files
uploaded via this option are
accessible via relative path. '#'
could be used as the separator of the
archive file path and the target
directory name. Comma (',') could be
used as the separator to specify
multiple archive files. This option
can be used to upload the virtual
environment, the data files used in
Python UDF (e.g., --pyArchives
file:///tmp/py37.zip,file:///tmp/data.
zip#data --pyExecutable
py37.zip/py37/bin/python). The data
files could be accessed in Python UDF,
e.g.: f = open('data/data.txt', 'r').
-pyexec,--pyExecutable <arg> Specify the path of the python
interpreter used to execute the python
UDF worker (e.g.: --pyExecutable
/usr/local/bin/python3). The python
UDF worker depends on Python 3.6+,
Apache Beam (version == 2.27.0), Pip
(version >= 7.1.0) and SetupTools
(version >= 37.0.0). Please ensure
that the specified environment meets
the above requirements.
-pyfs,--pyFiles <pythonFiles> Attach custom files for job. The
standard resource file suffixes such
as .py/.egg/.zip/.whl or directory are
all supported. These files will be
added to the PYTHONPATH of both the
local client and the remote python UDF
worker. Files suffixed with .zip will
be extracted and added to PYTHONPATH.
Comma (',') could be used as the
separator to specify multiple files
(e.g., --pyFiles
file:///tmp/myresource.zip,hdfs:///$na
menode_address/myresource2.zip).
-pym,--pyModule <pythonModule> Python module with the program entry
point. This option must be used in
conjunction with `--pyFiles`.
-pyreq,--pyRequirements <arg> Specify a requirements.txt file which
defines the third-party dependencies.
These dependencies will be installed
and added to the PYTHONPATH of the
python UDF worker. A directory which
contains the installation packages of
these dependencies could be specified
optionally. Use '#' as the separator
if the optional parameter exists
(e.g., --pyRequirements
file:///tmp/requirements.txt#file:///t
mp/cached_dir).
-s,--fromSavepoint <savepointPath> Path to a savepoint to restore the job
from (for example
hdfs:///flink/savepoint-1537).
-sae,--shutdownOnAttachedExit If the job is submitted in attached
