ubuntu 24.04 使用美国源安装最新版的docker

需求： 1.使用美国源安装最新版的docker; 2.使用美国源安装最新版的docker compose。

环境： 1.服务器：1台美国CN2大带宽（弹性），IP通过curl cip.cn显示为香港 2.操作系统：Ubuntu 24.04 LTS 3.IP address: 154.201.92.72

一、更新系统并安装依赖 1.更新和安装 运行 root@client:#apt-get update root@client:#apt-get install -y ca-certificates curl gnupg lsb-release

校验 root@client:~#curl --version

显示 curl 8.5.0 (x86_64-pc-linux-gnu) libcurl/8.5.0 OpenSSL/3.0.13 zlib/1.3 brotli/1.1.0 zstd/1.5.5 libidn2/2.3.7 libpsl/0.21.2 (+libidn2/2.3.7) libssh/0.10.6/openssl/zlib nghttp2/1.59.0 librtmp/2.3 OpenLDAP/2.6.7 Release-Date: 2023-12-06, security patched: 8.5.0-2ubuntu10.11 Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 pop3s rtmp rtsp scp sftp smb smbs smtp smtps telnet tftp Features: alt-svc AsynchDNS brotli GSS-API HSTS HTTP2 HTTPS-proxy IDN IPv6 Kerberos Largefile libz NTLM PSL SPNEGO SSL threadsafe TLS-SRP UnixSockets zstd

校验 root@client:~#gpg --version

二、添加 Docker 官方 GPG 密钥 1.创建密钥目录 运行 root@client:~#install -m 0755 -d /etc/apt/keyrings

2.下载并解密 GPG 密钥 运行 root@client:~#curl -fsSL download.docker.com/linux/ubunt… | gpg --dearmor -o /etc/apt/keyrings/docker.gpg chmod a+r /etc/apt/keyrings/docker.gpg

校验 root@client:~#ls -l /etc/apt/keyrings/docker.gpg

显示 -rw-r--r-- 1 root root 2760 Jul 16 11:48 /etc/apt/keyrings/docker.gpg

三、添加 Docker 官方 APT 源 1.添加 运行 root@client:~#echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu$(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null

校验 root@client:~#cat /etc/apt/sources.list.d/docker.list

显示 deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] download.docker.com/linux/ubunt… noble stable

四、安装最新版 Docker Engine 和 Compose 插件 1.安装 运行 root@client:~#apt-get update apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

校验 root@client:~#docker --version

显示 Docker version 29.6.1, build 8900f1d

校验 root@client:~#docker compose version

显示 Docker Compose version v5.3.1

五、启动 Docker 并设置开机自启 1.启动和激活 运行 root@client:#systemctl start docker root@client:#systemctl enable docker

校验 root@client:~#systemctl status docker
