Docker 镜像加速器

Docker Hub Docker Hub GitHub

您可以通过修改配置文件 /etc/docker/daemon.json 来使用加速器。如果 SSL 不是合法有效的证书，则必须配置 insecure-registries 跳过证书验证。具体的加速器配置样例如下：

sudo tee /etc/docker/daemon.json <<EOF
{
    "registry-mirrors": ["https://docker.{{host}}"],
    "insecure-registries": ["docker.{{host}}"],
    "exec-opts": ["native.cgroupdriver=systemd"]
}
EOF

# 重启 Docker 服务
sudo systemctl daemon-reload && sudo systemctl restart docker
