clash in docker tutorial (Linux)

1. Install the software

First installed dockerand docker-compose, ubuntu directly using apt

docker-compose the software is similar to the role of glue, the equivalent of the file, (multiple) mirrors glued together to use.
Through this software we will be able to link their profiles to clash clash use of docker mirror

2. Prepare the configuration file

The following description from the official

Prepare two documents together, one of which is
config.yaml
the need to replace this file into their clash configuration file, the following examples to the official website

port: 7890
socks-port: 7891

# `allow-lan` must be true in your config.yaml
allow-lan: true
external-controller: 0.0.0.0:8080

Another is the docker-composeconfiguration file without changing the file name must docker-compose.yml
be noted that under linux should bridge into a host

version: '3'
services:
  clash:
    image: dreamacro/clash
    volumes:
      - ./config.yaml:/root/.config/clash/config.yaml
    ports:
      - "7890:7890"
      - "7891:7891"
      # If you need external controller, you can export this port.
      # - "8080:8080"
    restart: always
    # When your system is Linux, you can use `network_mode: "host"` directly.
    network_mode: "bridge"
    container_name: clash

Wherein explain this line, the colon is the address of the machine in front of the document, after the colon is the mirror image address clash used to do a mapping
./config.yaml:/root/.config/clash/config.yaml

3. Use a mirror

In the two documents exist in the directory, use the command
sudo docker-compose up -d

-dIt indicates that the background to start
