To verify the value of NEXT_PUBLIC_API_BASE_URL available during
the frontend build stage, this commit adds an echo command to the
`new-frontend/Dockerfile`.
This will print the variable's value to the build logs immediately
before the `npm run build` command is executed. This helps diagnose
issues with the API base URL not being correctly passed or utilized
by the Next.js application, leading to incorrect API calls.
This series of fixes and improvements addresses issues related to Xray-core execution, Fail2ban configuration, frontend API calls, and Docker build processes.
Here's a summary of the key changes:
1. **Backend (`Dockerfile.backend`, `DockerEntrypoint.sh`):**
- I enabled CGo and installed SQLite dependencies.
- I installed Fail2ban.
- I created the `/app/bin` directory.
- I've ensured the Xray-core binary (`v1.8.11` for linux-amd64), `geoip.dat`, and `geosite.dat` are downloaded and correctly placed into `/app/bin/` with execute permissions.
- I copied custom Fail2ban filter (`3x-ipl.filter.conf`) and action (`3x-ipl.action.conf`) files to the appropriate directories in `/etc/fail2ban/`.
- I copied a custom `jail.local` (as `xui_fail2ban.local`) to `/etc/fail2ban/`. This configuration:
- Disables `sshd` and `sshd-ddos` jails.
- Sets `logpath` for the `[3x-ipl]` jail to `/app/log/3xipl.log`.
- I created the `/app/log` directory and the files `3xipl.log` and `3xipl-banned.log` to ensure they exist for Fail2ban.
- The `DockerEntrypoint.sh` script now checks for `fail2ban-client` before execution.
2. **Frontend (`new-frontend/Dockerfile`, `docker-compose.yml`):**
- I modified `new-frontend/Dockerfile` to include `ARG NEXT_PUBLIC_API_BASE_URL` and `ENV NEXT_PUBLIC_API_BASE_URL=$NEXT_PUBLIC_API_BASE_URL` before the `npm run build` command.
- I updated `docker-compose.yml` for the `frontend` service to pass `NEXT_PUBLIC_API_BASE_URL` as a build argument via the `args` section. This ensures the API base URL is correctly inlined during the Next.js build, fixing issues with API calls that were previously going to the frontend's own host and port.
3. **Docker Compose (`docker-compose.yml`):**
- I removed the obsolete `version: '3.8'` line.
4. **New Configuration Files (root of repo):**
- `xui_fail2ban.local`: Custom jail settings for Fail2ban.
- `3x-ipl.filter.conf`: Filter definition for 3x-ui IP limiting.
- `3x-ipl.action.conf`: Action definition for 3x-ui IP limiting.
These changes aim to provide a stable build and runtime environment, resolve frontend API call issues, and correctly configure Fail2ban.
You should pull these changes, rebuild your Docker images, and test thoroughly.
