docker开启远程访问

原文:docker开启远程访问

一，安装docker

1，服务器安装 docker

yum install docker

使用Docker 中国加速器

vim  /etc/docker/daemon.json

添加下面代码

{
  "registry-mirrors": ["https://registry.docker-cn.com"],
  "live-restore": true
}

（这个文件 初始状态是空的 只有“{}”）

启动服务

systemctl start docker
systemctl restart docker
systemctl stop docker

查看版本

 docker version

查看状态

service docker status

2，开启docker远程访问

vim  /etc/sysconfig/docker

在下面代码中添加红色部分

# /etc/sysconfig/docker

# Modify these options if you want to change the way the docker daemon runs
OPTIONS=‘--selinux-enabled --log-driver=journald --signature-verification=false‘
if [ -z "${DOCKER_CERT_PATH}" ]; then
    DOCKER_CERT_PATH=/etc/docker
fi

DOCKER_OPTS="-H unix:///var/run/docker.sock -H 0.0.0.0:2376"

# Do not add registries in this file anymore. Use /etc/containers/registries.conf
# instead. For more information reference the registries.conf(5) man page.

# Location used for temporary files, such as those created by
# docker load and build operations. Default is /var/lib/docker/tmp
# Can be overriden by setting the following environment variable.
# DOCKER_TMPDIR=/var/tmp

# Controls the /etc/cron.daily/docker-logrotate cron job status.
# To disable, uncomment the line below.
# LOGROTATE=false

# docker-latest daemon can be used by starting the docker-latest unitfile.
# To use docker-latest client, uncomment below lines
#DOCKERBINARY=/usr/bin/docker-latest
#DOCKERDBINARY=/usr/bin/dockerd-latest
#DOCKER_CONTAINERD_BINARY=/usr/bin/docker-containerd-latest
#DOCKER_CONTAINERD_SHIM_BINARY=/usr/bin/docker-containerd-shim-latest

修改服务配置：

vim /lib/systemd/system/docker.service

在下面代码中添加红色部分

重启docker网络

systemctl daemon-reload

重启docker服务

systemctl restart docker

　在浏览器输入：http://xxx.xxx.xxx:2376/info 或http://xxx.xxx.xxx:2376/version 显示版本信息表示开启成功
