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
COPY nginx/pig-ui.conf /etc/nginx/conf.d/
RUN /bin/bash -c 'echo init ok'
EXPOSE 80
CMD ["nginx","-g","daemon off;"]
(2)构建镜像
[root@k8s-master-node1 Pig]# docker build -t pig-nginx:v1.0 -f Dockerfile-nginx .
6.编排部署Pig快速开发平台
(1)编写docker-compose.yaml
[root@k8s-master-node1 Pig]# vi docker-compose.yaml
version: '2'

pig-mysql:
environment:
MYSQL_ROOT_PASSWORD: root

pig-nginx:
restart: always
image: pig-nginx:v1.0
container_name: pig-nginx
ports:
- 8888:80
links:
- pig-service:pig-gateway
(2)部署服务
[root@k8s-master-node1 Pig]# docker-compose up -d
查看服务
[root@k8s-master-node1 Pig]# docker-compose ps
