Fork

This fork replaced the alpine base image with container4armhf/armhf-alpine. It builds successfully (though slowly) on a Raspberry Pi 3.

docker-tor-hidden-service

Create a tor hidden service with a link

# run a container with a network application
$ docker run -d --name hello-world --restart always hypriot/armhf-hello-world

# and just link it to this container
$ docker run -d --name hidden-service --link hello-world --restart always dedimax/docker-tor-armhf-hidden-service

The .onion URLs are displayed to stdout at startup.

To keep onion keys, just mount volume /var/lib/tor/hidden_service/

$ docker run -it --link something --volume /path/to/keys:/var/lib/tor/hidden_service/ dedimax/docker-tor-armhf-hidden-service

Look at the docker-compose.yml file to see how to use it.

Setup

Set private key

Private key is settable by environment or by copying file in hostname/private_key in docker volume (hostname is the link name).

It's easier to pass key in environment with docker-compose.

    links:
      - hello
      - world
    environment:
        # Set private key
        HELLO_KEY: |
            -----BEGIN RSA PRIVATE KEY-----

            -----END RSA PRIVATE KEY-----

Options are set using the following pattern: LINKNAME_KEY

Setup port

Caution: Using PORT_MAP with multiple ports on single service will cause tor to fail.

Use link setting in environment with the following pattern: LINKNAME_PORTS.

Like docker, first port is exposed port and the second one is service internal port.

links:
  - hello
  - world
environment:
    # Set mapping ports
    HELLO_PORTS: 80:80

    # Multiple ports can be coma separated
    WORLD_PORTS: 8000:80,8888:80,22:22

Compose v2 support

Links setting are required when using docker-compose v2. See docker-compose.v2.yml for example.

Tools

A command line tool onions is available in container to get .onion url when container is running.

# Get services
$ docker exec -it torhiddenproxy_tor_1 onions
hello: vegm3d7q64gutl75.onion:80
world: b2sflntvdne63amj.onion:80

# Get json
$ docker exec -it torhiddenproxy_tor_1 onions --json
{"hello": ["b2sflntvdne63amj.onion:80"], "world": ["vegm3d7q64gutl75.onion:80"]}

Auto reload

Changing /etc/tor/torrc file trigger a SIGHUP signal to tor to reload configuration.

To disable this behavior, add ENTRYPOINT_DISABLE_RELOAD in environment.
