Dears,

I am using a simple nginx server as proxy to the docker socket, instead of enabling the remote API directly on Docker. Reason is: I would like some access restrictions, but simpler than the whole certificate thing.

Here is the nginx configuration:

upstream docker {
server unix:/var/run/docker.sock;
}

server {
listen 2375 default_server;
location / {
proxy_pass http://docker;
auth_basic_user_file /etc/nginx/.htpasswd;
auth_basic "Access restricted";
}
}

Say my server is http://docker-server:2735/

For any HTTP GET request initiated by the multiple commands, it succeeds if I set the URL as http://user:pass@docker-server:2735/

However, it fails when it comes to POST requests or DELETE requests. You'll find the full stack trace below.

I know this isn't how things should be done so ... Could you please advise me a possible alternative, or consider this as a feature request ?

Many thanks for your help.

Cheers from Belgium,

Eric
