Docker command line and background parameters

Docker official to provide users with a quick understanding of Docker provides an interactive tutorial designed to help users learn how to use the Docker command line. Docker command line

The following is a brief introduction to the Docker command list, detailed in a later section. You can get help on the command line by running Docker, or the Docker Assistance command (we still use the CoreOS for VMware as the operating environment, which is the case if you have no special instructions):

Core@localhost ~ $ docker usage:docker [OPTIONS] COMMAND [arg ...] -h=[unix:///var/run/docker.sock]: Tcp://host:port to Bind/connect to or unix://path/to/socket to use A self-sufficient ru

Basic usage: COMMAND + parameters

Core@localhost ~ $ docker Info
containers:7
images:123 Storage driver:btrfs Execution Driver
: native-0.2
Kernel version:3.16.2+
operating system:coreos 444.0.0
core@localhost ~ $ docker Version
Client version:1.2.0
client API version:1.14 go
version (client): go1.3.1
Git commit (client): Fa7b24f
  os/arch (client): linux/amd64
server version:1.2.0
server API version:1.14 go
version (server): go1.3.1
Git Commit (server): fa7b24f

The parameters of a single character can be put together:

Core@localhost ~ $ docker run-t-I ubuntu:14.04/bin/bash
#使用分开的参数
root@d512e393fc74:/# exit
exit
Core@localhost ~ $ docker run-ti ubuntu:14.04/bin/bash
#将当个支付的参数放在一起
root@d170dacef325:/# exit
exit
Core@localhost ~ $ docker rm d51 D17
#多个参数放在一行
d51
d17
core@localhost ~ $

Docker Background Process parameters

Parameters	introduce
--api-enable-cors=false	Remote API call.
-B,--bridge= ""	Bridging a bridge device on a system into a Docker container, where none can deactivate a network in a container
--bip= ""	Use CIDR addresses to set the IP of the Network Bridge. This parameter and-B cannot be used together.
-D,--debug=false	Turn on debug mode. Example: docker-d-D
-D,--daemon=false	Open daemon mode.
--dns=[]	The Settings container uses a DNS server. For example: docker-d--dns 8.8.8.8
-dns-search=[]	The settings container uses the specified DNS search domain name. such as: docker-d--dns-search example.com
--exec-driver= "native"	Sets the container to use the specified Run-time driver. such as: docker-d-e Lxc
-G,--group= "Docker"	In the background run mode, give the specified group to the appropriate UNIX socket. Note that when this parameter--group assigns an empty string, the group information is stripped
-G,--graph= "/var/lib/docker"	To set the Docker runtime root directory
-H,--host=[]	Set the socket bindings specified in background mode to bind one or more tcp://host:port, Unix:///path/to/socket, fd://*, or FD://SOCKETFD. such as: $ docker-h tcp://0.0.0.0:2375 PS or $ export docker_host= "tcp://0.0.0.0:2375" $ docker PS
-icc=true	Set up traffic that enables the inline container.
--ip= "0.0.0.0"	Set the default IP address to use when a container binds IP
--ip-forward=true	Set the Net.ipv4.ip_forward of the startup container
--iptables=true	Set iptable rules for starting Docker container customizations
--mtu=0	Sets the MTU value for the container network and, without this parameter, selects the default route MTU, which is set to a constant value of 1500 if there is no default route.
-P,--pidfile= "/var/run/docker.pid"	Sets the background process PID file path.
-R,--restart=true	Set up a container to run before restarting
-S,--storage-driver= ""	Set the container runtime to use the specified storage driver, such as specifying the use of Devicemapper, as follows: docker-d-S Devicemapper
--selinux-enabled=false	Setting Enable SELinux support
--storage-opt=[]	Setting Storage-driven parameters

Docker configuration file location

Docker configuration files can set most of the background process parameters, the storage location in each operating system is inconsistent

The location in Ubuntu is:/etc/default/docker

The position in the CentOS is:/etc/sysconfig/docker
