This commit addresses several issues I identified in the backend Docker container:
1. **Xray-core Execution Failure (`open bin/config.json`):**
- I modified `Dockerfile.backend` to correctly set up the Xray-core environment:
- It now creates the `/app/bin` directory.
- It downloads a specified version (v1.8.10) of Xray-core for linux-amd64, along with `geoip.dat` and `geosite.dat`, from the XTLS/Xray-core GitHub releases.
- It renames the Xray binary to `xray-linux-amd64` (matching the expected name pattern from `xray/process.go`) and places it, `geoip.dat`, and `geosite.dat` into `/app/bin/`.
- It makes the `/app/bin/xray-linux-amd64` binary executable.
- This ensures that the `x-ui` application can find the Xray binary and has a writable directory for `config.json`, resolving the "open bin/config.json: no such file or directory" errors.
2. **Fail2ban Configuration Error (`Have not found any log file for sshd jail`):**
- I created a new configuration file `xui_fail2ban.local`.
- This file is copied to `/etc/fail2ban/jail.local` within the Docker image.
- It explicitly disables the `[sshd]` jail, which was causing errors in an environment without an active sshd service or its logs.
- It ensures the `[3x-ipl]` jail (presumably for the panel's IP limiting) remains enabled, relying on the application to manage its specific filter and action rules.
3. **Docker Compose Version Warning:**
- I removed the `version: '3.8'` line from `docker-compose.yml` as it is obsolete and was causing a warning.
These changes aim to create a more stable and correctly configured backend service. You will need to rebuild the Docker images using `docker compose up -d --build --remove-orphans` to apply these fixes.
