Docker学习笔记_10 docker应用 - 部署TOMCAT服务
选择基镜像
基镜像使用dokcer hub官方提供的tomcat8 alpine当前最新版本，https://hub.docker.com/_/tomcat/
docker pull tomcat:8.5.32-jre8-alpine
docker tag tomcat:8.5.32-jre8-alpine 10.240.4.159/app/tomcat:8.5.32-alpine
docker push 10.240.4.159/app/tomcat:8.5.32-alpine

添加SSH支持
# 在宿主机上执行
mkdir -p /root/docker_build/tomcat-ssh
cd /root/docker_build/tomcat-ssh
cp /usr/share/zoneinfo/Asia/Shanghai .

创建VOLUME卷
# 在宿主机上执行 mkdir /docker_mnt/erpjs-tomcat # 下载的apache-tomcat-8.5.32.tar.gz上传到当前/tmp目录 cd /tmp tar zxvpf apache-tomcat-8.5.32.tar.gz cd apache-tomcat-8.5.32 cp -rf webapps /docker_mnt/erpjs-tomcat/ cp -rf conf /docker_mnt/erpjs-tomcat/ cp -rf logs /docker_mnt/erpjs-tomcat/
部署TOMCAT服务
- 登陆Rancher(1.6.18)，编排工具用的是默认的Cattle
- 应用 - 用户 - 添加应用 - 名称：[ERP-JS] - 创建
- 添加服务 - 在添加服务页面添写配置如下信息 - 创建
名称: tomcat 选择镜像: 10.240.4.159/erpjs/tomcat:8.5.32-alpine-ssh-erpjs 端口映射: 8080:8080/tcp 15922:22/tcp 卷 - 添加卷: /docker_mnt/erpjs-tomcat/webapps:/usr/local/tomcat/webapps /docker_mnt/erpjs-tomcat/conf:/usr/local/tomcat/conf /docker_mnt/erpjs-tomcat/logs:/usr/local/tomcat/logs 网络 - 主机名: erpjs 调度 - 在指定主机上运行全部容器: docker159
配置manager-gui
