Docker安装

卸载旧版本

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

一键安装

curl -fsSL https://get.docker.com | bash -s docker --mirror aliyun
or
curl -sSL https://get.daocloud.io/docker | sh

# dockerd-rootless-setuptool.sh install


curl -sSL https://get.daocloud.io/docker | sh
systemctl restart docker
systemctl enable docker
systemctl status docker

换为国内源

cat > /etc/docker/daemon.json<<EOF
{
    "registry-mirrors": ["https://registry.docker-cn.com","http://hub-mirror.c.163.com","https://docker.mirrors.ustc.edu.cn"]
}
EOF

cat >/etc/docker/daemon.json <<EOF
{
    "registry-mirrors" : [
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://cr.console.aliyun.com",
    "https://mirror.ccs.tencentyun.com"
  ]
}
EOF

systemctl restart docker


#失败了可以查看错误并重置
journalctl -xe
systemctl reset-failed docker.service

xxxxxxxxxx docker-compose up -dbash

ymir就是我们要创建并添加到docker组的普通用户

useradd ymir
groupadd docker
gpasswd -a ymir docker
systemctl restart docker

docker登录

docker login -u edclol1 -p bsNHv8D6YCmF@ej

Docker-Compose

curl -L "https://github.com/docker/compose/releases/download/1.29.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

docker-compose --version

增加远程连接

vim /etc/systemd/system/docker.service
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

systemctl daemon-reload
systemctl restart docker

cat >/etc/yum.repos.d/docker-ce.repo <<'END'
