Service wrapper

This little wrapper designed to allow service being controlled trough Telegram bot.

How to use

Container preparation

1. Download the binary from Releases page or build with CGO_ENABLED=0 go build -o wrapper ./src
2. Copy the binary to docker container
3. Create service.yml description file somewhere in the container. Example:

   service_name: Test service
   lines_to_preserve: 100
   # if true lines_to_preserve works separately for both outputs
   separate_stdout_stderr: true
   command: /bin/sh
   args:
     - -c
     - | # we also can use inline comments and multiline arguments
       echo 1
       sleep 1s
       echo 2 >&2
       echo 3

4. Change container entrypoint to ["/path/to/wrapper", "/path/to/service.yml"]
5. Well done :)

Container launch

Additionally to regular env, pass two variables more — WRAPPER_TELEGRAM_CHAT and WRAPPER_TELEGRAM_TOKEN. That's all
