架构图
1、构建tomcat镜像
1.1、基础环境准备
1.2、build-command脚本与Dockefile准备

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. # Note that Java 9 no longer supports this feature. # 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 # # JSSE_OPTS (Optional) Java runtime options used to control the TLS # implementation when JSSE is used. Default is: # "-Djdk.tls.ephemeralDHKeySize=2048" # # 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" # # USE_NOHUP (Optional) If set to the string true the start command will # use nohup so that the Tomcat process will ignore any hangup # signals. Default is "false" unless running on HP-UX in which # case the default is "true" # ----------------------------------------------------------------------------- JAVA_OPTS="-server -Xms1g -Xmx1g -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" # OS specific support. $var _must_ be set to either true or false. cygwin=false darwin=false os400=false hpux=false case "`uname`" in CYGWIN*) cygwin=true;; Darwin*) darwin=true;; OS400*) os400=true;; HP-UX*) hpux=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 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.

1.5、准备server.xml文件

2、构建tomcat镜像
2.1、清掉上篇文章sidercar方式部署的tomcat
3、编写tomcat k8s部署yaml文件
root@easzlab-deploy:~/20220821-case/20220821/ELK-cases/3.container-filebeat-process# cat 3.tomcat-app1.yaml kind: Deployment #apiVersion: extensions/v1beta1 apiVersion: apps/v1 metadata: labels: app: magedu-tomcat-app1-filebeat-deployment-label name: magedu-tomcat-app1-filebeat-deployment namespace: magedu spec: replicas: 3 selector: matchLabels: app: magedu-tomcat-app1-filebeat-selector template: metadata: labels: app: magedu-tomcat-app1-filebeat-selector spec: containers: - name: magedu-tomcat-app1-filebeat-container image: harbor.magedu.net/magedu/tomcat-app1:v1 #imagePullPolicy: IfNotPresent #如果本地存在image镜像,则自动跳过 imagePullPolicy: Always #不管本地是否存在镜像都要重新拉取,缺点比较消耗带宽 ports: - containerPort: 8080 protocol: TCP name: http env: - name: "password" value: "123456" - name: "age" value: "18" resources: limits: cpu: 1 memory: "512Mi" requests: cpu: 500m memory: "512Mi" root@easzlab-deploy:~/20220821-case/20220821/ELK-cases/3.container-filebeat-process# root@easzlab-deploy:~/20220821-case/20220821/ELK-cases/3.container-filebeat-process# root@easzlab-deploy:~/20220821-case/20220821/ELK-cases/3.container-filebeat-process# cat 4.tomcat-service.yaml --- kind: Service apiVersion: v1 metadata: labels: app: magedu-tomcat-app1-filebeat-service-label name: magedu-tomcat-app1-filebeat-service namespace: magedu spec: type: NodePort ports: - name: http port: 80 protocol: TCP targetPort: 8080 nodePort: 30092 selector: app: magedu-tomcat-app1-filebeat-selector root@easzlab-deploy:~/20220821-case/20220821/ELK-cases/3.container-filebeat-process#
3.1、部署tomcat
3.2、通过浏览器访问tomcat页面
3.3、测试容器能否连接kafka
3.4、查看kafka集群是否有数据传输过来
3.5、配置logstash虚机采集kafka集群filebeat日志
cat logstash-filebeat-process-kafka-to-es.conf
input { kafka { bootstrap_servers => "172.16.88.176:9092,172.16.88.177:9092,172.16.88.178:9092" topics => ["filebeat-magedu-app1"] codec => "json" } } output { if [fields][type] == "filebeat-tomcat-catalina" { elasticsearch { hosts => ["172.16.88.173:9200","172.16.88.174:9200"] index => "filebeat-tomcat-catalina-%{+YYYY.MM.dd}" }} if [fields][type] == "filebeat-tomcat-accesslog" { elasticsearch { hosts => ["172.16.88.173:9200","172.16.88.174:9200"] index => "filebeat-tomcat-accesslog-%{+YYYY.MM.dd}" }} }
3.6、重启logstash服务
systemctl restart logstash.service
3.7、检查es集群是否创建新的filebeat索引
3.8、参照https://www.cnblogs.com/cyh00001/p/16618335.html 上篇文章:在kibana创建fiebeat索引
3.9、将pod副本数调大既可以生成tomcat-access 日志
