Docker container is a mirror image of the running instance, a container with a required run-time writable file layer, and the image is a static read-only file. You can use the command to view the Docker docker container help support the operation of container sub-command.
First, create a boot image &
1.1. Create a container command (man docker-create the parameters available to view) command so that the new vessel is stopped.
语法：docker create [OPTIONS] CONTAINER [COMMAND] [ARG...]
Apline create a container with 3.8 version:
docker create -it alpine:3.8
1.2. Start container command (man docker-start parameters can be viewed), to start the container has been created.
语法：docker start [OPTIONS] [CONTAINER] [CONTAINER...]
CONTAINER: represents a plurality of containers can be started simultaneously.
1.3. Create and launch container command (man docker-run parameters can be viewed), after stop container you can also use the command to start the container.
语法：docker run [OPTIONS] CONTAINER [COMMAND]
Common parameters:
-it: -i represents the standard input is held open, -t indicates whether to allocate a pseudo-terminal;
-d: Indicates whether the container runs in the background;
--rm: Indicates whether to delete the container exit;
-p: a map showing port;
--name: alias specified container;
When creating a run and start the container, Docker in the background standards are as follows:
- Check whether there is a local mirror, then download the image does not exist;
- the use of image creation and launch container;
- a file system assigned to the container, and one read-only and writable mirror mount the outer layer;
- bridging host configuration from the host bridge interface to a virtual interface to the container;
- configure an IP address from the address pool container to the bridge;
- execution of the application specified by the user;
- after the implementation of the container is automatically terminated;
Create and launch container, and allow user interaction (exit or ctrl + d to Quit):
docker run -it alpine:3.8 /bin/sh
1.4. Restart command container (man docker-restart parameter can be viewed).
语法：docker restart [OPTIONS] CONTAINER [COMMAND]
This command will run in a container before termination, then restart.
Second, the View container container logs & View
2.1. See container list command (man docker-ps parameters can be viewed).
Syntax: Docker PS [the OPTIONS]
Common parameters:
-a, --all: show all containers, comprising a container is stopped;
-f, --filter: filter container (e.g. -f --name = ne $, ne represents the ending vessel name);
-l, --latest: display container recently created;
--no-trunc: do not truncate the output of content (sometimes incomplete command that is too long column appears);
2.2. See container information command (man docker-inspect parameters can be viewed).
Syntax: Docker the Inspect [the OPTIONS] NAME | ID
See vessel network configuration, grep to see which filter configuration, -A specified number of rows to be displayed:
docker inspect 8d | grep Networks -A 20
2.3. Inner vessel view process (parameter available to man docker-top view).
Syntax: Docker Top CONTAINER
2.4. See container statistics (man docker-stats parameters can be viewed) is displayed using the CPU, memory, storage, network situation information.
Syntax: Docker stats [the OPTIONS] [CONTAINER ...]
docker stats -a
2.5. See outputting content container (man docker-logs parameters available to view), is used to obtain the output container.
语法：docker logs [OPTIONS] CONTAINER
Common parameters:
-f, -follow: sustained output;
-tail string: the output of a number of recent log:
-t, -timestamps: display timestamp information;
-since string: a log output start time;
-until string: you Log output before a certain time;
-details: print details;
Third, enter & Stop & delete container
3.1 into the container command (man docker-exec parameters can be viewed).
语法：docker exec [OPTIONS] CONTAINER COMMAND [ARG...]
Into the container:
docker exec -it 8d /bin/sh
3.2. 暂停&恢复容器命令(参数可用man docker-pause 或 man docker-unpause来查看)。
语法：docker pause CONTAINER [CONTAINER...] / docker unpause CONTAINER [CONTAINER...]
暂停和恢复容器：
3.3. 终止容器命令(参数可用man docker-stop)。
语法：docker stop [OPTIONS] CONTAINER [CONTAINER...]
这个命令会先向容器发送SIGTERM信号，等待一段超时时间后(默认10s)，再发送SIGKILL信号来终止容器。
清除所有处于停止状态的容器：
docker container prune
3.4. 删除容器命令(参数可用man docker-rm)。
语法：docker rm [OPTIONS] CONTAINER [CONTAINER...]
常用参数：
-f, --force：是否强行终止一个运行中的容器，在没有-f参数时，rm只能删除已经停止或退出状态的容器，不能删除运行中的容器；
-l, --link：删除容器的连接，但保留容器；
-v, --volumes：删除容器挂载的数据卷；
四、导入&导出容器
4.1. 导出容器命令(参数可用man docker-export来查看)，用于导出容器到tar文件，这个tar文件是容器当时的快照状态。
语法：docker export [OPTIONS] CONTAINER
将容器在当前目录导出为alpine.tar的文件：
docker export -o alpine2.tar 8d
或
docker export > alpine2.tar 8d
4.2. 导入容器命令(参数可用man docker-import来查看)，用于导入tar文件变为镜像。
语法：docker import [OPTIONS] FILE|URL [REPOSITORY[:TAG]]
将alpine.tar容器快照到本地镜像库，和load的区别在于：镜像存储文件会保存所有历史记录，而容器快照文件会丢弃所有历史记录和元数据信息，在导入时可以重新指定标签等元数据信息。
docker import alpine2.tar alpine:2
五、其他容器命令
5.1. 复制文件命令(参数可用man docker-cp来查看)，用于容器和主机之间复制文件。
语法：docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH | docker cp [OPTIONS] SRC_PATH CONTAINER:DEST_PATH
复制本地文件到容器里：
vi test.sh docker cp test.sh 8d:/
复制容器文件到本地：
docker cp 8d:/etc/passwd /root
5.2. 查看容器变更命令(参数可用man docker-diff来查看)。
语法：docker diff CONTAINER
5.3. 查看容器端口映射(参数可用man docker-port来查看)：
语法：docker port CONTAINER
5.4. 更新容器配置(参数可用man docker-update来查看)，用于更新容器一些运行时配置：
语法：docker port [OPTIONS] CONTAINER [CONTAINER...]
