Ubuntu24.04 安装Docker

1. 参考

2. 卸载已安装的Docker

bash 复制代码

sudo apt remove $(dpkg --get-selections docker.io docker-compose docker-compose-v2 docker-doc podman-docker containerd runc | cut -f1)

3. 添加仓库

bash 复制代码

sudo apt update
sudo apt install -y ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings

3.1 使用官方仓库:

bash 复制代码

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

bash 复制代码

sudo tee /etc/apt/sources.list.d/docker.sources <<EOF
Types: deb
URIs: https://download.docker.com/linux/ubuntu
Suites: $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}")
Components: stable
Signed-By: /etc/apt/keyrings/docker.asc
EOF

bash 复制代码

sudo apt update

3.2 使用阿里云仓库（推荐）

bash 复制代码

sudo curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

bash 复制代码

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] http://mirrors.aliyun.com/docker-ce/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

3.3 更新软件索引

bash 复制代码

sudo apt update

4. 安装Docker

4.1 安装软件

bash 复制代码

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

4.2 查看运行状态

启动服务

bash 复制代码

sudo systemctl start docker && sudo systemctl enable docker

查看状态

bash 复制代码
