docker基本命令

1、docker build -t register_url/namespace/csphere/centos:lastest 根据Dockerfile构建镜像

2、docker images 显示镜像的大小

3、通过docker 镜像生成docker容器 docker run -it 交互启动 -d 后端启动 -大P 2222:22 宿主机将端口（下次启动时端口随机生成）替换为容器22 -p 2222:22创建2222来隐射docker 22 --name "name" csphere/centos:7.1 镜像

sky@ubuntu:/opt/program/docker-training/centos7$ sudo docker run -d -p 2222:22 --name base csphere/centos:7.1
72b407bc822c61d13b95082aa732bf1a8535a118c646273845813c473612d5ce

4、进入docker

sky@ubuntu:/opt/program/docker-training/php-fpm$ sudo docker exec -it website /bin/bash
[root@c5cc1d4aa35f /]#

5、删除镜像

sky@ubuntu:/opt/program/docker-training/mysql$ sudo docker rm dbserver
Error response from daemon: You cannot remove a running container 39d71dec5b640cf409c36077caef4c132b4547fa8941b0c05f3da15eef2f7d1e. Stop the container before attempting removal or force remove
sky@ubuntu:/opt/program/docker-training/mysql$ 
sky@ubuntu:/opt/program/docker-training/mysql$ sudo docker rm -f dbserver
dbserver

6、参数输入：

docker run -d -p 3306:3306 -v host_dir:container_dir
==》
sky@ubuntu:/opt/program/docker-training/mysql$ sudo docker run -d -p 3306:3306 -v /var/lib/docker/vfs/dir/mydata:/var/lib/mysql csphere/mysql:5.5
39d5fab1865b76d12cdf78ac13fe256ac2ab844953aee15f1734f43c1e165900

7、映射文件路径后查看(重新挂载后文件还在)

sky@ubuntu:/opt/program/docker-training/mysql$ cd /var/lib/docker/vfs/dir/mydata/
sky@ubuntu:/var/lib/docker/vfs/dir/mydata$ ls
aria_log.00000001  ibdata1      ib_logfile1  mysql       performance_schema
aria_log_control   ib_logfile0  mydb         mysql.sock  test

8、停止docker容器

sky@ubuntu:/var/lib/docker/vfs/dir/mydata$sudo docker stop 39d

9、删除docker

sky@ubuntu:/var/lib/docker/vfs/dir/mydata$sudo docker rm 39d

10、添加变量

sky@ubuntu:/opt/program/docker-training/wordpress$ docker run -d -p 80:80 --name wordpress -e WORDPRESS_DB_HOST=192.168.31.129 -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=root csphere/wordpress:4.2

11、启动elk(保证不是root和文件有权限)

sudo docker run -d -p 5601:5601 -p 9200:9200 -p 5044:5044 -p 9300:9300
　　-v /opt/program/dockerconf/elasticsearch/data:/var/lib/elasticsearch
　　-v /opt/program/dockerconf/elasticsearch/config/elasticsearch.yml:/etc/elasticsearch/elasticsearch.yml
　　-v /opt/program/dockerconf/elasticsearch/config/jvm.options:/etc/elasticsearch/jvm.options
　　--name elk-slave sebp/elk

docker run -p 27017:27017 -v $PWD/db:/data/db -d mongo:3.2

docker run -it mongo:3.2 mongo --host 172.17.0.1
