2.2、构建消费者镜像
2.3、部署消费者服务
[root@easzlab-deploy consumer]# vi consumer.yaml [root@easzlab-deploy consumer]# cat consumer.yaml kind: Deployment #apiVersion: extensions/v1beta1 apiVersion: apps/v1 metadata: labels: app: magedu-consumer name: magedu-consumer-deployment namespace: magedu spec: replicas: 3 selector: matchLabels: app: magedu-consumer template: metadata: labels: app: magedu-consumer spec: containers: - name: magedu-consumer-container image: harbor.magedu.net/app3/dubbo-demo-consumer:v1 #command: ["/apps/tomcat/bin/run_tomcat.sh"] #imagePullPolicy: IfNotPresent imagePullPolicy: Always ports: - containerPort: 80 protocol: TCP name: http --- kind: Service apiVersion: v1 metadata: labels: app: magedu-consumer name: magedu-consumer-server namespace: magedu spec: type: NodePort ports: - name: http port: 80 protocol: TCP targetPort: 80 #nodePort: 30001 selector: app: magedu-consumer [root@easzlab-deploy consumer]#
当consumer pod副本由2调整为3，此时通过日志可以查看到consumer被轮询调度
三、部署管理端
3.1、准备管理端服务相关文件

Instead put them into a script # setenv.sh in CATALINA_BASE/bin to keep your customizations separate. # # CATALINA_HOME May point at your Catalina "build" directory. # # CATALINA_BASE (Optional) Base directory for resolving dynamic portions # of a Catalina installation. If not present, resolves to # the same directory that CATALINA_HOME points to. # # CATALINA_OUT (Optional) Full path to a file where stdout and stderr # will be redirected. # Default is $CATALINA_BASE/logs/catalina.out # # CATALINA_OPTS (Optional) Java runtime options used when the "start", # "run" or "debug" command is executed. # Include here and not in JAVA_OPTS all options, that should # only be used by Tomcat itself, not by the stop process, # the version command etc. # Examples are heap size, GC logging, JMX ports etc. # # CATALINA_TMPDIR (Optional) Directory path location of temporary directory # the JVM should use (java.io.tmpdir). Defaults to # $CATALINA_BASE/temp. # # JAVA_HOME Must point at your Java Development Kit installation. # Required to run the with the "debug" argument. # # JRE_HOME Must point at your Java Runtime installation. # Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME # are both set, JRE_HOME is used. # # JAVA_OPTS (Optional) Java runtime options used when any command # is executed. # Include here and not in CATALINA_OPTS all options, that # should be used by Tomcat and also by the stop process, # the version command etc. # Most options should go into CATALINA_OPTS. # # JAVA_ENDORSED_DIRS (Optional) Lists of of colon separated directories # containing some jars in order to allow replacement of APIs # created outside of the JCP (i.e. DOM and SAX from W3C). # It can also be used to update the XML parser implementation. # Defaults to $CATALINA_HOME/endorsed. # # JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start" # command is executed. The default is "dt_socket". # # JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start" # command is executed. The default is localhost:8000. # # JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start" # command is executed. Specifies whether JVM should suspend # execution immediately after startup. Default is "n". # # JPDA_OPTS (Optional) Java runtime options used when the "jpda start" # command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS, # and JPDA_SUSPEND are ignored. Thus, all required jpda # options MUST be specified. The default is: # # -agentlib:jdwp=transport=$JPDA_TRANSPORT, # address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND # # CATALINA_PID (Optional) Path of the file which should contains the pid # of the catalina startup java process, when start (fork) is # used # # LOGGING_CONFIG (Optional) Override Tomcat's logging config file # Example (all one line) # LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties" # # LOGGING_MANAGER (Optional) Override Tomcat's logging manager # Example (all one line) # LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager" # ----------------------------------------------------------------------------- JAVA_OPTS="-server -Xms512m -Xmx512m -Xss512k -Xmn1g -XX:CMSInitiatingOccupancyFraction=65 -XX:+UseFastAccessorMethods -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:+DisableExplicitGC -XX:MaxTenuringThreshold=10 -XX:NewSize=2048M -XX:MaxNewSize=2048M -XX:NewRatio=2 -XX:PermSize=128m -XX:MaxPermSize=512m -XX:CMSFullGCsBeforeCompaction=5 -XX:+ExplicitGCInvokesConcurrent -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:LargePageSizeInBytes=128m -XX:+UseFastAccessorMethods" # OS specific support. $var _must_ be set to either true or false. cygwin=false darwin=false os400=false case "`uname`" in CYGWIN*) cygwin=true;; Darwin*) darwin=true;; OS400*) os400=true;; esac # resolve links - $0 may be a softlink PRG="$0" while [ -h "$PRG" ]; do ls=`ls -ld "$PRG"` link=`expr "$ls" : '.*-> \(.*\)$'` if expr "$link" : '/.*' > /dev/null; then PRG="$link" else PRG=`dirname "$PRG"`/"$link" fi done # Get standard environment variables PRGDIR=`dirname "$PRG"` # Only set CATALINA_HOME if not already set [ -z "$CATALINA_HOME" ] && CATALINA_HOME=`cd "$PRGDIR/.." >/dev/null; pwd` # Copy CATALINA_BASE from CATALINA_HOME if not already set [ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME" # Ensure that neither CATALINA_HOME nor CATALINA_BASE contains a colon # as this is used as the separator in the classpath and Java provides no # mechanism for escaping if the same character appears in the path. case $CATALINA_HOME in *:*) echo "Using CATALINA_HOME: $CATALINA_HOME"; echo "Unable to start as CATALINA_HOME contains a colon (:) character"; exit 1; esac case $CATALINA_BASE in *:*) echo "Using CATALINA_BASE: $CATALINA_BASE"; echo "Unable to start as CATALINA_BASE contains a colon (:) character"; exit 1; esac # Ensure that any user defined CLASSPATH variables are not used on startup, # but allow them to be specified in setenv.sh, in rare case when it is needed.
