(Don't include 184 | the brackets!) The text should be enclosed in the appropriate 185 | comment syntax for the file format. We also recommend that a 186 | file or class name and description of purpose be included on the 187 | same "printed page" as the copyright notice for easier 188 | identification within third-party archives. 189 | 190 | Copyright [yyyy] [name of copyright owner] 191 | 192 | Licensed under the Apache License, Version 2.0 (the "License"); 193 | you may not use this file except in compliance with the License. 194 | You may obtain a copy of the License at 195 | 196 | http://www.apache.org/licenses/LICENSE-2.0 197 | 198 | Unless required by applicable law or agreed to in writing, software 199 | distributed under the License is distributed on an "AS IS" BASIS, 200 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 201 | See the License for the specific language governing permissions and 202 | limitations under the License. 203 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Docker Socket Proxy 2 | 3 | [](https://microbadger.com/images/tecnativa/docker-socket-proxy:latest "Get your own version badge on microbadger.com") 4 | [](https://microbadger.com/images/tecnativa/docker-socket-proxy:latest "Get your own image badge on microbadger.com") 5 | [](https://microbadger.com/images/tecnativa/docker-socket-proxy:latest "Get your own commit badge on microbadger.com") 6 | [](https://microbadger.com/images/tecnativa/docker-socket-proxy "Get your own license badge on microbadger.com") 7 | 8 | ## What? 9 | 10 | This is a security-enhanced proxy for the Docker Socket. 11 | 12 | ## Why? 13 | 14 | Giving access to your Docker socket could mean giving root access to your host, 15 | or even to your whole swarm, but some services require hooking into that socket 16 | to react to events, etc. Using this proxy lets you block anything you consider 17 | those services should not do. 18 | 19 | ## How? 20 | 21 | We use the official [Alpine][]-based [HAProxy][] image with a small 22 | configuration file. 23 | 24 | It blocks access to the Docker socket API according to the environment 25 | variables you set. It returns a `HTTP 403 Forbidden` status for those dangerous 26 | requests that should never happen. 27 | 28 | ## Security recommendations 29 | 30 | - Never expose this container's port to a public network. Only to a Docker 31 | networks where only reside the proxy itself and the service that uses it. 32 | - Revoke access to any API section that you consider your service should not 33 | need. 34 | - This image does not include TLS support, just plain HTTP proxy to the host 35 | Docker Unix socket (which is not TLS protected even if you configured your 36 | host for TLS protection). This is by design because you are supposed to 37 | restrict access to it through Docker's built-in firewall. 38 | - [Read the docs](#suppported-api-versions) for the API version you are using, 39 | and **know what you are doing**. 40 | 41 | ## Usage 42 | 43 | 1. Run the API proxy (`--privileged` flag is required here because it connects with the docker socket, which is a privileged connection in some SELinux/AppArmor contexts and would get locked otherwise): 44 | 45 | $ docker container run \ 46 | -d --privileged \ 47 | --name dockerproxy \ 48 | -v /var/run/docker.sock:/var/run/docker.sock \ 49 | -p 127.0.0.1:2375:2375 \ 50 | tecnativa/docker-socket-proxy 51 | 52 | 2. Connect your local docker client to that socket: 53 | 54 | $ export DOCKER_HOST=tcp://localhost 55 | 56 | 3.
