docker 安装

docker 安装， https://docs.docker.com/engine/install/ubuntu/

# Add Docker's official GPG key: sudo apt-get update sudo apt-get install ca-certificates curl sudo install -m 0755 -d /etc/apt/keyrings sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc sudo chmod a+r /etc/apt/keyrings/docker.asc # Add the repository to Apt sources: echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \ $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null sudo apt-get update apt-cache madison docker-ce | awk '{ print $3 }' VERSION_STRING=5:23.0.0-1~ubuntu.22.04~jammy sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin

支付宝扫码登录 阿里云， 得到 docker 阿里云 个人 镜像加速 url， https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://fe2ajwut.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker docker目录迁移

查看docker占用空间

sudo du -d 1 -c -h -t 100MB /var/lib/docker

1.4G /var/lib/docker/overlay2 19G /var/lib/docker/volumes 20G /var/lib/docker 20G 总计 docker版本 23.0.0

docker --version==Docker version 23.0.0, build e92dd87

错误方法

启动dockersudo systemctl start docker报错失败的方法:

软链接 /var/lib/docker ---> /docker_data"graph": "/docker_data"添加到 /etc/docker/daemon.json 正确方法

配置文件 /etc/docker/daemon.json中 添加字段 "data-root": "/docker_data"

该配置文件/etc/docker/daemon.json内容如下:

{ "registry-mirrors": ["https://fe2ajwut.mirror.aliyuncs.com"], "data-root": "/docker_data" }
