使用 jwilder-nginx-proxy 而不安装 docker socket

如何解决使用 jwilder-nginx-proxy 而不安装 docker socket

我正在努力遵循 docker-bench-security 的准则。我正在努力遵守此规则：Ensure the Docker socket is not mounted inside any containers。

我已经读到 jwilder-nginx-proxy 如果可以通过 HTTPS 访问它，则不需要安装 docker 套接字。

我认为我的 docker 安装工作正常，我可以从我的主机与 docker API 通信：

curl https://127.0.0.1:2376/version --cert /home/ubuntu/.docker/cert.pem   --key /home/ubuntu/.docker/key.pem   --cacert /home/ubuntu/.docker/ca.pem
{"Platform":{"Name":"Docker Engine - Community"},"Components":...}

但我无法从 Nginx jwilder 访问它：

******@******:~/docker/proxy$ docker exec -ti Nginx bash
root@c4740dcc00d9:/app# curl https://127.0.0.1:2376/version --cert /home/ubuntu/.docker/cert.pem   --key /home/ubuntu/.docker/key.pem   --cacert /home/ubuntu/.docker/ca.pem
curl: (7) Failed to connect to 127.0.0.1 port 2376: Connection refused
root@c4740dcc00d9:/app#  curl https://172.17.0.1:2376/version --cert /home/ubuntu/.docker/cert.pem   --key /home/ubuntu/.docker/key.pem   --cacert /home/ubuntu/.docker/ca.pem -m 5
curl: (28) Connection timed out after 5000 milliseconds

这是我的docker-compose.yml：

Nginx:
  container_name: Nginx
  image: jwilder/Nginx-proxy
  ports:
    - 80:80
    - 443:443
  environment:
    DOCKER_HOST: tcp://127.0.0.1:2376
    DOCKER_TLS_VERIFY:
    DOCKER_CERT_PATH:
  volumes:
    - ./certs:${DOCKER_CERT_PATH}

还有 daemon.json 文件：

{
        "icc": false,"userns-remap": "default","log-driver": "local","live-restore": true,"tls": true,"tlsverify": true,"tlscacert": "/etc/docker/ssl/ca.pem","tlscert": "/etc/docker/ssl/daemon-cert.pem","tlskey": "/etc/docker/ssl/daemon-key.pem","hosts": ["unix:///var/run/docker.sock","tcp://127.0.0.1:2376"],"default-ulimit": "nofile=50:100","userland-proxy": false
}

我不知道如何通过 jwilder 访问 docker API。 docker-compose 文件上有什么要添加的吗？还是在 docker 配置中？我应该使用哪个地址从容器到达它？

预先感谢为我指明正确的方向！
