实战交付一套dubbo微服务到k8s集群(4)之dubbo微服务底包镜像制作

1.下载jre镜像

在运维主机(mfyxw50.mfyxw.com)操作

[root@mfyxw50 ~]# docker pull registry.cn-hangzhou.aliyuncs.com/yfhub/jre8:8u112

2.把jre上传至私有仓库

在运维主机(mfyxw50.mfyxw.com)上操作

[root@mfyxw50 ~]# docker images | grep jre
[root@mfyxw50 ~]# docker tag registry.cn-hangzhou.aliyuncs.com/yfhub/jre8:8u112 harbor.od.com/public/jre8:8u112
[root@mfyxw50 ~]# docker login harbor.od.com
[root@mfyxw50 ~]# docker push harbor.od.com/public/jre8:8u112

3.自定义Dockerfile文件

在运维主机(mfyxw50.mfyxw.com)上操作

[root@mfyxw50 ~]# mkdir -p /data/dockerfile/jre8
[root@mfyxw50 ~]# cat > /data/dockerfile/jre8/Dockerfile << EOF
FROM harbor.od.com/public/jre8:8u112
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\
    echo 'Asia/Shanghai' >/etc/timezone
ADD config.yml /opt/prom/config.yml
ADD jmx_javaagent-0.3.1.jar /opt/prom/
WORKDIR /opt/project_dir
ADD entrypoint.sh /entrypoint.sh
CMD ["/entrypoint.sh"]
EOF

config.yml文件

[root@mfyxw50 ~]# cat > /data/dockerfile/jre8/config.yml << EOF
---
rules:
  - pattern: '.*'
EOF

entrypointsh文件

[root@mfyxw50 ~]# cat > /data/dockerfile/jre8/entrypoint.sh << EOF
#!/bin/sh
M_OPTS="-Duser.timezone=Asia/Shanghai -javaagent:/opt/prom/jmx_javaagent-0.3.1.jar=\$(hostname -i):\${M_PORT:-"12346"}:/opt/prom/config.yml"
C_OPTS=\${C_OPTS}
JAR_BALL=\${JAR_BALL}
exec java -jar \${M_OPTS} ${C_OPTS} \${JAR_BALL}
EOF

下载jmx_javaagent-0.3.1.jar文件

[root@mfyxw50 ~]# wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.3.1/jmx_prometheus_javaagent-0.3.1.jar -O /data/dockerfile/jre8/jmx_javaagent-0.3.1.jar

4.在harbor里创建一个公有的base(所有底包)仓库

5.build底包并打标签

在运维主机(mfyxw50.mfyxw.com)上操作

[root@mfyxw50 ~]# cd /data/dockerfile/jre8/
[root@mfyxw50 jre8]# ls
config.yml  Dockerfile  entrypoint.sh  jmx_javaagent-0.3.1.jar
[root@mfyxw50 jre8]# docker build . -t harbor.od.com/base/jre8:8u112

6.把build出来的jre8底包上传到私有仓库

在运维主机(mfyxw50.mfyxw.com)上操作

[root@mfyxw50 ~]# docker images | grep jre

[root@mfyxw50 ~]#
