基于docker-compose编排部署Pig微服务快速开发框架

1.规划节点

IP	主机名	节点
192.168.100.10	master	docker-compose节点

2.基础准备

将软件包上传至master节点/root目录下

案例实施

1.基础环境准备

(1)上传软件包

[root@k8s-master-node1 ~]# ls
anaconda-ks.cfg  chinaskills_cloud_paas_v2.0.2.iso  Pig.tar.gz
[root@k8s-master-node1 ~]# tar -zxvf Pig.tar.gz

导入Centos:7.9.2009镜像

[root@k8s-master-node1 ~]# docker load -i Pig/CentOS_7.9.2009.tar

查看集群状态

[root@k8s-master-node1 ~]# kubectl cluster-info
Kubernetes control plane is running at https://apiserver.cluster.local:6443
CoreDNS is running at https://apiserver.cluster.local:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

2.容器化部署MariaDB

(1)编写Dockerfile

编写mysql_init.sh脚本

[root@k8s-master-node1 ~]# cd Pig/
[root@k8s-master-node1 Pig]# vi mysql_init.sh 
#!/bin/bash
mysql_install_db --user=root
mysqld_safe --user=root &
sleep 8
mysqladmin -uroot password 'root'
mysql -uroot -proot -e "grant all on *.* to identified by 'root';flush privileges;"
mysql -uroot -proot -e "source /opt/pig_codegen.sql;source /opt/pig_config.sql;source /opt/pig_job.sql;source /opt/pig.sql;"

编写Yum源

[root@k8s-master-node1 Pig]# vi local.repo 
[pig]
name=pig
baseurl=file:///root/yum
gpgcheck=0
enabled=1

编写Dockerfile文件

[root@k8s-master-node1 Pig]# vi Dockerfile-mysql 
FROM centos:centos7.9.2009
MAINTAINER CSQ
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
ENV LC_ALL en_US.UTF-8
RUN yum install -y mariadb-server
COPY mysql /opt/
COPY mysql_init.sh /opt/
RUN bash /opt/mysql_init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]

(2)构建镜像

[root@k8s-master-node1 Pig]# docker build -t pig-mysql:v1.0 -f Dockerfile-mysql .

3.容器化部署Redis

(1)编写Dockerfile

[root@k8s-master-node1 Pig]# vi Dockerfile-redis
FROM centos:centos7.9.2009
MAINTAINER CSQ
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
RUN yum install -y redis
RUN sed -i 's/127.0.0.1/0.0.0.0/g' /etc/redis.conf && \
    sed -i 's/protected-mode yes/protected-mode no/g' /etc/redis.conf
EXPOSE 6379
CMD ["/usr/bin/redis-server","/etc/redis.conf"]

(2)构建镜像

[root@k8s-master-node1 Pig]# docker build -t pig-redis:v1.0 -f Dockerfile-redis .

4.容器化部署Pig

(1)编写Dockerfile

编写启动文件

[root@k8s-master-node1 Pig]# vi pig_init.sh 
#!/bin/bash
nohup java -jar /root/pig-register.jar $JAVA_OPTS >/dev/null 2>&1 &
sleep 8
nohup java -jar /root/pig-gateway.jar $JAVA_OPTS >/dev/null 2>&1 &
sleep 8
nohup java -jar /root/pig-auth.jar $JAVA_OPTS >/dev/null 2>&1 &
sleep 8
nohup java -jar /root/pig-upms.jar &JAVA_OPTS >/dev/null 2>&1

编写Dockerfile文件

[root@k8s-master-node1 Pig]# vi Dockerfile-pig 
FROM centos:centos7.9.2009
MAINTAINER CSQ
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
ADD service /root/
RUN yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel
COPY pig_init.sh /root/
RUN chmod +x /root/pig_init.sh
CMD ["/bin/bash","/root/pig_init.sh"]

(2)构建镜像

[root@k8s-master-node1 Pig]# docker build -t pig-service:v1.0 -f Dockerfile-pig .

5.容器化部署前端服务

(1)编写Dockerfile

[root@k8s-master-node1 Pig]# vi Dockerfile-nginx
FROM centos:centos7.9.2009
MAINTAINER CSQ
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
RUN yum install -y nginx
COPY nginx/dist /data
