Docker & Compose安装以及入门-优快云博客

博客主要介绍了Docker和Docker Compose的安装方法。Docker安装包括脚本安装、配置加速器和卸载操作；Docker Compose安装有二进制包安装、PIP安装等方式，还给出了案例。此外，还提及了Docker常用命令，如查看镜像、容器及进入容器等。

Docker 安装

脚本安装

自定义脚本

wget https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/stable/Packages/docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm
yes | yum localinstall docker-ce-18.03.1.ce-1.el7.centos.x86_64.rpm
systemctl start docker
# add aliyun accelarater
touch /etc/docker/daemon.json
cat>>/etc/docker/daemon.json<<EOF 
{
    "insecure-registries" : ["0.0.0.0/0"],
    "registry-mirrors": ["https://4wmjwi37.mirror.aliyuncs.com"],
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "10m",
        "max-file": "3"
    }
}
EOF
systemctl daemon-reload
systemctl restart docker
docker info

docker社区

curl -sSL https://get.docker.com | sh
docker -v

阿里云脚本

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
docker -v

daocloud脚本
shell curl -sSL https://get.daocloud.io/docker | sh docker -v

配置加速器

阿里云

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://dist7hw1.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
docker info

DaoCloud

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://ced808ab.m.daocloud.io
sudo systemctl restart docker
docker info

卸载 Docker

卸载脚本
shell #sudo apt-get remove docker docker-engine docker.io sudo yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-selinux \ docker-engine-selinux \ docker-engine rm -fr /var/lib/docker/

Docker Compose安装

二进制包安装（推荐）

官网
https://github.com/docker/compose/releases

安装脚本

sudo curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo docker-compose -v

卸载脚本

sudo rm -rf /usr/local/bin/docker-compose

PIP 安装

#pip -V
#安装 python-pip
yum -y install epel-release
yum -y install python-pip
pip install --upgrade pip
pip -V
sudo pip install -U docker-compose
docker-compose -version
