Boot configuration file for Docker under CentOS

The first step, locate the Docker.service file

The contents are as follows:

After=network.target

Wants=docker-storage-setup.service

[Service]

Type=notify

Environmentfile=-/etc/sysconfig/docker

Environmentfile=-/etc/sysconfig/docker-storage

Environmentfile=-/etc/sysconfig/docker-network

Environment=gotraceback=crash

Execstart=/usr/bin/docker-d $OPTIONS \

$DOCKER _storage_options \

$DOCKER _network_options \

$ADD _registry \

$BLOCK _registry \

$INSECURE _registry

limitnofile=1048576

limitnproc=1048576

Limitcore=infinity

Mountflags=slave

[Install]

Wantedby=multi-user.target

The second step, configuration options and so on parameters, such as I want to configure the log maximum length max-size=10k (note that the Docker 1.8 version only supports this configuration)

options= '--log-opt max-size=10k '

The third step, when the container is generated (Docker Deamon will be executed when the configuration is started Execstart )
