12.实战交付一套dubbo微服务到k8s集群(5)之交付dubbo-monitor到K8S集群

dubbo-monitor官方源码地址：https://github.com/Jeromefromcn/dubbo-monitor

1.下载dubbo-monitor源码并解压

[root@hdss7- src]# wget https://github.com/Jeromefromcn/dubbo-monitor/archive/master.zip
[root@hdss7- src]# mkdir -p /data/dockerfile/dubbo-monitor
[root@hdss7- src]# unzip /opt/src/dubbo-monitor-master.zip
[root@hdss7- src]# cp -R /opt/src/dubbo-monitor-master/* /data/dockerfile/dubbo-monitor/

2.修改dubbo-monitor配置文件

[root@hdss7- src]# vim /data/dockerfile/dubbo-monitor/dubbo-monitor-simple/conf/dubbo_origin.properties
dubbo.container=log4j,spring,registry,jetty
dubbo.application.name=dubbo-monitor
dubbo.application.owner=Maple
dubbo.registry.address=zookeeper://zk1.fx.com:2181?backup=zk2.fx.com:2181,zk3.fx.com:2181
dubbo.protocol.port=
dubbo.jetty.port=
dubbo.jetty.directory=/dubbo-monitor-simple/monitor
dubbo.charts.directory=/dubbo-monitor-simple/charts
dubbo.statistics.directory=/dubbo-monitor-simple/statistics
dubbo.log4j.file=logs/dubbo-monitor-simple.log
dubbo.log4j.level=WARN

3.修改dubbo-monitor启动文件

[root@hdss7- src]# vim /data/dockerfile/dubbo-monitor/dubbo-monitor-simple/bin/start.sh
#!/bin/bash
sed -e "s/{ZOOKEEPER_ADDRESS}/$ZOOKEEPER_ADDRESS/g" /dubbo-monitor-simple/conf/dubbo_origin.properties > /dubbo-monitor-simple/conf/dubbo.properties
cd `dirname $`
BIN_DIR=`pwd`
cd ..
DEPLOY_DIR=`pwd`
CONF_DIR=$DEPLOY_DIR/conf

SERVER_NAME=`sed '/dubbo.application.name/!d;s/.*=//' conf/dubbo.properties | tr -d '\r'`
SERVER_PROTOCOL=`sed '/dubbo.protocol.name/!d;s/.*=//' conf/dubbo.properties | tr -d '\r'`
SERVER_PORT=`sed '/dubbo.protocol.port/!d;s/.*=//' conf/dubbo.properties | tr -d '\r'`
LOGS_FILE=`sed '/dubbo.log4j.file/!d;s/.*=//' conf/dubbo.properties | tr -d '\r'`

if [ -z "$SERVER_NAME" ]; then
    SERVER_NAME=`hostname`
fi

PIDS=`ps -f | grep java | grep "$CONF_DIR" |awk '{print $2}'`
if [ -n "$PIDS" ]; then
    echo "ERROR: The $SERVER_NAME already started!"
    echo "PID: $PIDS"
    exit
fi

if [ -n "$SERVER_PORT" ]; then
    SERVER_PORT_COUNT=`netstat -tln | grep $SERVER_PORT | wc -l`
    if [ $SERVER_PORT_COUNT -gt  ]; then
        echo "ERROR: The $SERVER_NAME port $SERVER_PORT already used!"
        exit
    fi
fi

LOGS_DIR=""
if [ -n "$LOGS_FILE" ]; then
    LOGS_DIR=`dirname $LOGS_FILE`
else
    LOGS_DIR=$DEPLOY_DIR/logs
fi
if [ ! -d $LOGS_DIR ]; then
    mkdir $LOGS_DIR
fi
STDOUT_FILE=$LOGS_DIR/stdout.log

LIB_DIR=$DEPLOY_DIR/lib
LIB_JARS=`ls $LIB_DIR|grep .jar|awk '{print "'$LIB_DIR'/"$0}'|tr "\n" ":"`

JAVA_OPTS=" -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true "
JAVA_DEBUG_OPTS=""
if [ "$1" = "debug" ]; then
    JAVA_DEBUG_OPTS=" -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n "
fi
JAVA_JMX_OPTS=""
if [ "$1" = "jmx" ]; then
    JAVA_JMX_OPTS=" -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false "
fi
JAVA_MEM_OPTS=""
BITS=`java -version >& | grep -i -bit`
if [ -n "$BITS" ]; then
    JAVA_MEM_OPTS=" -server -Xmx128m -Xms128m -Xmn32m -XX:PermSize=16m -Xss256k -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:LargePageSizeInBytes=128m -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=70 "
else
    JAVA_MEM_OPTS=" -server -Xms128m -Xmx128m -XX:PermSize=16m -XX:SurvivorRatio=2 -XX:+UseParallelGC "
fi

echo -e "Starting the $SERVER_NAME ...\c"
exec java $JAVA_OPTS $JAVA_MEM_OPTS $JAVA_DEBUG_OPTS $JAVA_JMX_OPTS -classpath $CONF_DIR:$LIB_JARS com.alibaba.dubbo.container.Main > $STDOUT_FILE >&

4.构建dubbo-monitor镜像并上传至私有仓库

[root@hdss7- src]# cd /data/dockerfile/dubbo-monitor
[root@hdss7- dubbo-monitor]# docker build . -t harbor.fx.com/infra/dubbo-monitor:latest
[root@hdss7-200 dubbo-monitor]# docker push harbor.fx.com/infra/dubbo-monitor:latest

5.准备dubbo-monitor的资源配置清单

[root@hdss7- ~]# mkdir -p /data/k8s-yaml/dubbo-monitor

Deployment.yaml文件

[root@hdss7- dubbo-monitor]# vim Deployment.yaml
kind: Deployment
apiVersion: extensions/v1beta1
metadata:
  name: dubbo-monitor
  namespace: infra
  labels:
    name: dubbo-monitor
spec:
  replicas:
  selector:
    matchLabels:
      name: dubbo-monitor
  template:
    metadata:
      labels:
        app: dubbo-monitor
        name: dubbo-monitor
    spec:
      containers:
      - name: dubbo-monitor
        image: harbor.fx.com/infra/dubbo-monitor:latest
      imagePullSecrets:
      - name: harbor
      terminationGracePeriodSeconds:
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable:
      maxSurge:
  revisionHistoryLimit:
  progressDeadlineSeconds: 

svc.yaml

[root@hdss7- dubbo-monitor]# vim svc.yaml
kind: Service
apiVersion: v1
metadata:
  name: dubbo-monitor
  namespace: infra
spec:
  ports:
  - protocol: TCP
    port:
    targetPort:
  selector:
    app: dubbo-monitor

Ingress.yaml

[root@hdss7- dubbo-monitor]# vim Ingress.yaml
kind: Ingress
apiVersion: extensions/v1beta1
metadata:
  name: dubbo-monitor
  namespace: infra
spec:
  rules:
  - host: dubbo-monitor.fx.com
    http:
      paths:
      - path: /
        backend:
          serviceName: dubbo-monitor
          servicePort: 

6.应用dubbo-monitor资源配置清单文件

[root@hdss7- ~]#  kubectl apply -f http://k8s-yaml.fx.com/dubbo-monitor/Deployment.yaml
[root@hdss7- ~]#  kubectl apply -f http://k8s-yaml.fx.com/dubbo-monitor/svc.yaml
[root@hdss7- ~]#  kubectl apply -f http://k8s-yaml.fx.com/dubbo-monitor/Ingress.yaml

7.DNS解析域名dubbo-monitor

[root@hdss7- ~]# vim /var/named/fx.com.zone
$ORIGIN fx.com.
$TTL         ;  minutes
@               IN SOA  dns.fx.com. dnsadmin.fx.com. (
                          ; serial
                               ; refresh ( hours)
                                 ; retry ( minutes)
                              ; expire ( week)
                               ; minimum ( day)
                         )
                        NS      dns.fx.com.
$TTL  ;  minute
dns             A       10.4.7.11
harbor          A       10.4.7.200
k8s-yaml        A       10.4.7.200
traefik         A       10.4.7.10
dashboard       A       10.4.7.10
zk1             A       10.4.7.11
zk2             A       10.4.7.12
zk3             A       10.4.7.21
jenkins         A       10.4.7.10
dubbo-monitor   A       10.4.7.10

[root@hdss7-11 ~]# systemctl restart named
[root@hdss7-11 ~]# dig -t A dubbo-monitor.fx.com @10.4.7.11 +short
