Add distroless Dockerfile and implement internal health check (#3366)
- rslib(http_server): add `is_running()` method
- rslib(sync): introduce `--healthcheck` argument for health probe in distroless
- doc(syncserver): add table comparing Dockerfile and Dockerfile.distroless
- Expand cross-platform support with distroless
- add `Dockerfile.distroless`

- Dockerfile: bump rust `1.79` to `1.80.1`
- Dockerfile: bump alpine `3.20` to `3.20.2`

Note: Implemented an internal health check because distroless images do not include curl, which is used to reduce image size and attack surface. For more details, see https://blog.sixeyed.com/docker-healthchecks-why-not-to-use-curl-or-iwr/

fix: failed: check:format:rust

typo

remove extra space

fix failed:check:format:rust

update doc

fetch `host` and `port` using envy

fix: failed: check:format:rust

Update doc + add dockerignore

- dockerignore: This helps avoid sending unwanted files and directories to the builder
- add new line
- I am still experimenting cross platform compilation, I am getting

# Building and running Anki sync server in Docker
This is an example Dockerfile contributed by an Anki user, which shows how you can run a self-hosted sync server,
similar to what AnkiWeb.net offers.
Building and running the sync server within a container has the advantage of fully isolating
the build products and runtime dependencies from the rest of your system.
## Requirements
- [x] [Docker](https://docs.docker.com/get-started/)
| **Aspect** | **Dockerfile** | **Dockerfile.distroless** |
| ---------------------- | ---------------------------------------------------------- | --------------------------------------------------------- |
| **Shell & Tools** | ✅ Includes shell and tools | ❌ Minimal, no shell or tools |
| **Debugging** | ✅ Easier debugging with shell and tools | ❌ Harder to debug due to minimal environment |
| **Health Checks** | ✅ Supports complex health checks | ❌ Health checks need to be simple or directly executable |
| **Image Size** | ❌ Larger image size | ✅ Smaller image size |
| **Customization** | ✅ Easier to customize with additional packages | ❌ Limited customization options |
| **Attack Surface** | ❌ Larger attack surface due to more installed packages | ✅ Reduced attack surface |
| **Libraries** | ✅ More libraries available | ❌ Limited libraries |
| **Start-up Time** | ❌ Slower start-up time due to larger image size | ✅ Faster start-up time |
| **Tool Compatibility** | ✅ Compatible with more tools and libraries | ❌ Compatibility limitations with certain tools |
| **Maintenance** | ❌ Higher maintenance due to larger image and dependencies | ✅ Lower maintenance with minimal base image |
# Building image
To proceed with building, you must specify the Anki version you want, by replacing `<version>` with something like `23.12.1` and `<Dockerfile>` with the chosen Dockerfile (e.g., `Dockerfile` or `Dockerfile.distroless`)
```bash
# Execute this command from the root directory of your project
docker build -f docs/syncserver/<Dockerfile> --no-cache --build-arg ANKI_VERSION=<version> -t anki-sync-server .
```
# Run container
Once done with build, you can proceed with running this image with the following command:
```bash
# this will create anki server
docker run -d -e "SYNC_USER1=admin:admin" -p 8080:8080 --name anki-sync-server anki-sync-server
```
However, if you want to have multiple users, you have to use the following approach:
```bash
# this will create anki server with multiple users
docker run -d -e "SYNC_USER1=test:test" -e "SYNC_USER2=test2:test2" -p 8080:8080 --name anki-sync-server anki-sync-server
```
Moreover, you can pass additional env vars mentioned [here](https://docs.ankiweb.net/sync-server.html)
