docker清理 mp.weixin.qq.com/s/y4vjmRBa-…

以root权限进入容器 sudo docker exec -it -u root 容器id /bin/bash

  • 实时查看docker容器名为s12的最后10行日志
  • $ sudo docker logs -f -t --tail 10 s12
  • 查看Docker信息
  • docker info
  • 下载镜像
  • docker pull busybox
  • BusyBox是一个最小的Linux系统
  • 运行一个带标签镜像的容器
  • sudo docker run -t -i ubuntu:14.04 /bin/bash
  • 跑个Hello World
  • docker run busybox /bin/echo Hello World
  • 构建容器
  • sample_job=$(docker run -d busybox /bin/sh -c "while true;do echo Docker;sleep 1;done")
  • 其中的-d是放在后台执行
  • 查看日志
  • docker logs $sample_job
  • 名为sample_job的容器，停止命令是
  • docker stop $sample_job
  • 重启该容器
  • docker restart $sample_job
  • 要将容器删除，需要先将容器停止，容器删除命令为：
  • docker rm $sample_job
  • 将容器的状态保存为新的镜像的方法为：
  • docker commit
  • 查看镜像
  • docker images
  • 搜索镜像
  • docker search (image-name)
  • 查看镜像的历史版本
  • docker history (image-name)
  • 将镜像推送到registry
  • docker push (image-name)
  • 查看我们正在运行的容器
  • docker ps -l
  • 端口映射
  • docker run -d -p 5000:5000 training/webapp python app.py
  • 移除镜像
  • docker rmi（镜像名称或者id前3位）

docker部署

blog.csdn.net/weixin_4268… jar包docker部署 1.部署的jar包配置maven pom 2.添加docker file 3.配置服务器上的docker.service 4.配置idea 的docker插件 maven插件参考mario-rich

docker安装

docs.docker.com/engine/inst…

docker 镜像加速

sudo cp -n /lib/systemd/system/docker.service /etc/systemd/system/docker.service
sudo sed -i "s|ExecStart=/usr/bin/docker daemon|ExecStart=/usr/bin/docker daemon --registry-mirror=<your accelerate address>|g" /etc/systemd/system/docker.service
sudo sed -i "s|ExecStart=/usr/bin/dockerd|ExecStart=/usr/bin/dockerd --registry-mirror=<your accelerate address>|g" /etc/systemd/system/docker.service
sudo systemctl daemon-reload
sudo service docker restart

容器

#dockerfile
FROM java:8
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo '$TZ' > /etc/timezone

安装mysql

docker run -itd --name mysql-test -p 3306:3306 -e MYSQL_ROOT_PASSWORD=rich mysql:latest 或

version: '3'
services:
  mysql:
    image: mysql:latest
    environment:
      MYSQL_ROOT_PASSWORD: **
    ports:
      - 3306:3306
    volumes:
      - "/root/db-data/mysql/:/var/lib/mysql"
    restart: always

#chmod 777 /root/db-data/mysql/

搭建maven私有仓库

www.jianshu.com/p/09a6cab37… docker run -d -p 8081:8081 --name nexus -v /root/nexus-data:/var/nexus-data --restart=always sonatype/nexus3

docker exec -it 511d6878bca5 /bin/bash
获取登陆密码
cd nexus-data/
cat admin.password 登录后可以自定义修改密码
