ChangesSSL bypass startup
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to When only one SSL file is configured, the new bypass can silently ignore it and expose the panel over plaintext HTTP, potentially transmitting credentials without encryption; that configuration should be rejected before merge. The Unix-socket warning also reports the wrong bind target, while documenting the opt-in remains a bounded follow-up. Suggested reviewers: Poem

In `@main.py`:
- Around line 119-124: Update the server configuration branching around
ServerSettings.has_ssl and dangerously_bypass_ssl so the bypass path is allowed
only when both SSL certificate and key paths are absent. Detect and reject
partial certificate/key configuration before selecting plain HTTP, rather than
silently ignoring the configured SSL path.
- Around line 120-136: The warning around the bind configuration must report the
actual target: use server_settings.uds when a Unix socket is configured, and use
server_settings.host with server_settings.port only for TCP binding. Update the
bind-target interpolation in the warning before the existing uds/host/port
assignment logic, preserving the rest of the warning text.

Summary
Docker/Podman containers with bridged network can only publish ports that are bound to
0.0.0.0. Right now, when PasarGuard runs withoutUVICORN_SSL_CERTFILE/UVICORN_SSL_KEYFILE, it restricts binding to127.0.0.1only, making panel unreachable from the host when fronted by a TLS terminating reverse proxy like Nginx, Caddy or Traefik.This adds an opt-in
UVICORN_DANGEROUSLY_BYPASS_SSLflag that binds to the configured host/port even without certificates. It defaults toFalse, so the current secure behavior is unchanged unless explicitly opted in.Type of change
Checklist
Testing
Running container with flag set to
True:Running container without setting the flag or set to
False:Notes for reviewers
First of all: I fully agree with the mandatory SSL policy. I think it's an excellent safeguard for people's security, and that's exactly why I did not add any mention of this flag to
.env.exampleor the SSL warning message. I don't want users casually bypassing it.The flag exists only for real edge cases. Because running HTTPS inside a private network between the PasarGuard container and the reverse proxy container is meaningless, the TLS termination belongs at the host proxy, not inside the container. For people who hit this and know exactly what they're doing, the mandatory policy otherwise blocks a legitimate deployment with zero security benefit.
Average developer, have no problem with cloning repository, removing checks and building image locally (Even non-technical person can do it with the help of AI), but it just adds unwanted work for them. That's exactly why this PR was made, developers who understand things they do, can easily discover this flag and use it, while remaining out of scope for average Joe, since it never gets mentioned anywhere and isn't available directly in
.envfile by default. However, happy to add and properly document this feature, if maintainers prefer it this way.Thanks for your work!
