安装 docker-compose

现在一般不用手动安装了，跟着官方文档安装好docker engine之后，docker-compose就会自动安装好了。

Ubuntu,Debian

apt update
apt install -y docker-compose-plugin

CentOS

yum update
yum install -y docker-compose-plugin

手动安装

curl -L "https://github.com/docker/compose/releases/download/2.11.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker compose version

配置HTTP代理

创建配置文件

mkdir -p /etc/systemd/system/docker.service.d \
nano /etc/systemd/system/docker.service.d/http-proxy.conf

http-proxy.conf：

[Service]
Environment="HTTP_PROXY=http://<你的代理>:<端口>"
Environment="HTTPS_PROXY=http://<你的代理>:<端口>"
Environment="NO_PROXY=localhost,127.0.0.1,docker-registry.example.com"

重载配置

systemctl daemon-reload && systemctl restart docker

查看配置

systemctl show --property=Environment docker
