Run clock-bound-d on Docker

[ohkinozomu]

Hello.
I would like to run clock-bound-d on Docker, but there are probably two barriers.

1. clock-bound-d currently supports only syslog logging.

I wrote the following Dockerfile, but this gives me an error.

FROM rust:1.59.0-bullseye
RUN cargo install clock-bound-d --version 0.1.1
CMD ["clockboundd"]

thread 'main' panicked at 'could not connect to syslog: Error(Initialization, State { next_error: Some(Error(Io(Os { code: 2, kind: NotFound, message: "No such file or directory" }), State { next_error: None, backtrace: InternalBacktrace })), backtrace: InternalBacktrace })', /usr/local/cargo/registry/src/github.com-1ecc6299db9ec823/clock-bound-d-0.1.1/src/main.rs:65:42
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

2. clock-bound-d supports only 323 port.

When running clock-bound-d on Docker, I'm thinking of running chrony as a side car.
For example, I'm thinking of using https://github.com/cturra/docker-ntp , which works with port 123.
I think a workaround is possible, but it would be useful to be able to use a port other than 323.

Are there any plans to make these two points configurable?

Hi,

Can work on adding the configuration option for the port, should be simple enough. As for the syslog, I don't see why syslog won't be working on the docker. Would you be able to verify if syslog is installed and running on your Docker?

I'll work on it (I'm not familiar with Rust, so it will take some time).

Syslog is not installed and not running in my Docker image.
It may be possible to run syslog in Docker by some hacky way ( https://stackoverflow.com/questions/47973554/how-to-let-syslog-workable-in-docker ), but I don't think it is the Docker way.
STDOUT/STDERR should be used.
If for some reason clock-bound-d relies on syslog, it should be clearly stated that it doesn't support Docker.

Open to patches to add support for stdout/stderr, theres no hard dependency on syslog.
