x4gking/3x-ui-upgrade

3x-ui-Upgrade is a ready made deployment setup for running Heimdall, an improved fork of the popular 3x-ui panel, on the Railway hosting platform. It bundles the panel together with an nginx reverse proxy so that the web panel, the subscription link, and the VLESS over WebSocket connection all share a single port, which matches how Railway assigns ports to deployed projects. The database is SQLite by default, so no separate Postgres database is needed unless someone expects a very large number of users. To deploy it, a person creates a new GitHub repository containing the three files this project provides: a Dockerfile, an nginx configuration template, and a start script. In Railway, they choose New Project, then Deploy from GitHub repo, and point it at that repository. Railway detects the Dockerfile automatically and builds it, downloading the latest version of Heimdall during the build. After the deployment finishes, the user opens the networking settings, generates a public domain, and makes sure the target port is set to 3000, since that is the port nginx listens on internally. Once deployed, the panel is reached at a managepanel path on the generated domain, using the default admin username and password, which should be changed right away. Setting up a VLESS inbound requires specific values such as listen port 8080, the ws network type, no extra transport security, and a custom path. The project explains how to build a working client connection link and notes that a subscription link is automatically available under a sub path on the same domain. The README warns that panel settings such as users and inbounds are stored on the container's temporary filesystem, so a Railway Volume should be attached to a specific directory to avoid losing that data on every redeploy. It also notes that switching to Postgres for larger user counts would require manually editing the Dockerfile and start script, since this version only supports SQLite out of the box.
