docker

1、常用命令

* 查看镜像信息
docker images 

* 查看正在运行的容器
docker ps  

* 查看所有容器
docker ps -a


* 进入容器
docker exec -it 51b9527f1d88 /bin/bash

* 进入数据库
mysql -uroot -pSaiwen.web123

* 创建并进入容器
docker run -it --entrypoint /bin/bash registry.saiwentech.com:35000/library/tomcat:7.0_1.7

- 导出镜像
docker save -o ucp1.1.7.tar.gz ucp:1.1.7
docker save -o /mnt/home/mobile/ucp1.1.7_docker_image.tar.gz 303d0cc15269

- 导入镜像
docker load -i xxx.tar.gz

- 下载镜像
docker pull 170.18.10.40/ucpplus-b/ucp:1.1.7


查看容器日志
docker logs --tail 50 --follow --timestamps 79921b85086b
docker logs --tail 350 --follow --timestamps mobile_ucp_db_1 


- 查看容器
docker run -ti <your_Container_image>

- 查看镜像详细信息
docker inspect d49f922a0111

- 镜像改名
docker tag imageid name:tag

停止容器
docker stop mobile_ucp_1 mobile_ucp_db_1 mobile_ucp_mongo_db_1
docker start :启动一个或多少已经被停止的容器
docker stop :停止一个运行中的容器
docker restart :重启容器
http://www.runoob.com/docker/docker-run-command.html

* 建立镜像  （ucp:1.1.7 .   后面有个点）
cd /mnt/home/mobile/ucp1.1.7
docker build -f docker/Dockerfile  -t ucp:1.1.7 .


* 初始化设置（建立容器）
docker run -it -v /mnt/opt/data/ucp1.1.7/config/ucp/:/opt/saiwentech/autoconfig/conf/ ucp:1.1.7 config -d


* 启动容器
cd /mnt/home/mobile
docker-compose -f docker-compose-ucp1.1.7.yml up -d



* 请注意控制台输出，如果有错误，请按照错误信息修改配置，重新制作镜像
镜像删除操作
docker rmi ucp:1.1.7
如果发现有关联的容器未删除，请先停止容器后删除容器后，再次尝试删除镜像
docker rm 【容器id】

* 删除镜像后，重新制作镜像时，要把原来的mongo、mysql数据删掉
/mnt/opt/data/ucp1.1.7/mysql/data
/mnt/opt/data/ucp1.1.7/mongo/data

提交镜像
docker commit 678ae48535b1 ucp:1.1.7
docker commit  -m "ucp1.1.7--20180428" -a "xyq" f54f18474f15 ucp:1.1.7
    -a :提交的镜像作者；
    -c :使用Dockerfile指令来创建镜像；
    -m :提交时的说明文字；
    -p :在commit时，将容器暂停。

上传到170.18.10.40镜像仓库
    登陆 docker login http://170.18.10.40 
         docker login http://registry.saiwentech.com:35000

    标记 docker tag ucp:1.1.7 170.18.10.40/ucpplus-b/ucp:1.1.7       （170.18.10.120 开发）
         docker tag ucp:1.1.7 170.18.10.40/mobile/ucp:1.1.7          （170.18.10.162 测试）

    上传 docker push 170.18.10.40/ucpplus-b/ucp:1.1.7
         docker push 170.18.10.40/mobile/ucp:1.1.7

    账号/密码
    徐 yqxu Yqxu123456


    docker login http://registry.saiwentech.com:35000
    yqxu Yqxu123456


    现有docker仓库地址使用ip地址，导致外网无法正常下载镜像。
    现在统一修改为registry.saiwentech.com:35000

    上传方式为：
    docker push registry.saiwentech.com:35000/mobile/IMAGE[:TAG]
    下载方式：
    docker pull registry.saiwentech.com:35000/mobile/IMAGE[:TAG]
    docker pull registry.saiwentech.com:35000/library/mysql:5.7.7_saiwen2

参数设置
/mnt/opt/data/ucp1.1.7/config/ucp/antx.properties

docker参数配置
/mnt/home/mobile/ucp1.1.7/install/ROOT/META-INF/autoconf/auto-config.xml

源文件位置
/mnt/home/mobile/ucp1.1.7



初始化时可能不能创建数据库，需要手动创建  
创建数据库
CREATE DATABASE UCPPLUS DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;


mysql 添加配置文件 /mnt/opt/data/ucp1.1.7/mysql/conf/add.cnf

[mysqld]
sql_mode='NO_ENGINE_SUBSTITUTION'

2、docker安装问题

2.1、使用 yum 安装

http://www.runoob.com/docker/centos-docker-install.html
Docker 要求 CentOS 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。
通过 uname -r 命令查看你当前的内核版本
[root@runoob ~]# uname -r 3.10.0-327.el7.x86_64

[root@runoob ~]# yum -y install docker-io

[root@runoob ~]# service docker start

镜像加速

 /etc/docker/daemon.json
{
  "registry-mirrors": ["http://hub-mirror.c.163.com"]
}

镜像加速 阿里云 针对Docker客户端版本大于1.10.0的用户
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://eo6mflje.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker


docker --version
docker info

Dockers 服务开机启动：
sudo systemctl enable docker.service

安装docker，启动不成功，报错信息  
https://www.2cto.com/net/201803/730799.html

Error starting daemon: SELinux is not supported with the overlay2 graph driver on this kernel. Either boot into a newer kernel or disable selinux in docker (--selinux-enabled=false)

意思是说：此linux的内核中的SELinux不支持 overlay2 graph driver ，解决方法有两个，要么启动一个新内核，要么就在docker里禁用selinux，--selinux-enabled=false

重新编辑docker配置文件：

vi /etc/sysconfig/docker

设置 --selinux-enabled=false

然后systemctl start docker


登陆仓库失败时：
[root@localhost ~]# docker login http://registry.saiwentech.com:35000
Username: yqxu
Password: 
Error response from daemon: Get https://registry.saiwentech.com:35000/v1/users/: http: server gave HTTP response to HTTPS client

需要修改   
    vi /lib/systemd/system/docker.service
在ExecStart后添加     
    ExecStart=/usr/bin/dockerd  --insecure-registry=registry.saiwentech.com:35000 --insecure-registry=registry:35000
再重启
systemctl daemon-reload
sudo systemctl restart docker

Ubuntu 16.04（LTS）安装dockerI

$ sudo apt-get update

$ sudo apt-get install docker

查看docker服务是否启动：

$ systemctl status docker

若未启动，则启动docker服务：

$ sudo systemctl start docker

sudo apt-get update && sudo apt-get upgrade

2.2、安装mongo

http://www.runoob.com/docker/docker-install-mongodb.html
docker search mongo    查找Docker Hub上的mongo镜像

docker pull mongo:3.2

docker pull mysql:5.7.7

2.3、安装docker-compose

http://www.cnblogs.com/52fhy/p/5991344.html

curl -L https://github.com/docker/compose/releases/download/1.8.0/run.sh > /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

docker-compose -version

卸载docker-compose
https://yeasy.gitbooks.io/docker_practice/content/compose/install.html#%E5%8D%B8%E8%BD%BD
如果是二进制包方式安装的，删除二进制文件即可。
rm /usr/local/bin/docker-compose

* 报错 Unsupported config option for services service: 'ucp_db'  。docker-compose版本低了。


https://stackoverflow.com/questions/36724948/docker-compose-unsupported-config-option-for-services-service-web

Support for the version 2 compose file format was introduced in docker-compose version 1.6, released around February of this year.

You are using 1.3.3, from July 2015.

You need to upgrade to a more recent version to use the version 2 format configuration files.

2.4、阿里云镜像push

* 镜像上传阿里云 cr.console.aliyun.com


  $ sudo docker login --username=明明之明夜 registry.cn-hangzhou.aliyuncs.com
  $ sudo docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/saiwen/ucp:[镜像版本号]
  $ sudo docker push registry.cn-hangzhou.aliyuncs.com/saiwen/ucp:[镜像版本号]

  sudo docker push registry.cn-hangzhou.aliyuncs.com/saiwen/ucp:1.1.7
  sudo docker push registry.cn-hangzhou.aliyuncs.com/saiwen/ucp:mysql_5.7.7
  sodu docker push registry.cn-hangzhou.aliyuncs.com/saiwen/ucp:mongo_3.2.9

2.5、测试 run 运行容器

docker run --name base -tid 170.18.10.40/library/baseenv:base /bin/bash

dockcer pull tomcat:6.0.53

docker run --name tomcat6.0.53 -p 8081:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d docker.io/tomcat:6.0.53

docker run --name some-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

docker run -p 3306:3306 --name mymysql -v

/mnt/opt/data/ucp1.1.7/mysql/conf:/etc/mysql/conf.d -v

/mnt/opt/data/ucp1.1.7/mysql/logs:/logs -v

/mnt/opt/data/ucp1.1.7/mysql/data:/mysql_data -e
MYSQL_ROOT_PASSWORD=Saiwen.web123 -d registry.cn-hangzhou.aliyuncs.com/saiwen/ucp:mysql_5.7.7
