Running inside Docker

Apache + PHP,
live in your browser.

This page is served by Apache and rendered by PHP inside an Alpine Linux container. The terminal next door gives you a root shell in that very same container, with OpenCode AI installed and ready to run.

No VM, no SSH client — just a container and a WebSocket.

The stack

Four small pieces, one container

Everything runs inside a single Alpine Linux image, supervised by supervisord.

Alpine Linux

v3.20.10

A tiny musl-based distribution. This is the root filesystem behind the terminal.

PHP

8.3.36

Runs as an Apache module via mod_php. This page is the proof.

Apache httpd

Apache/2.4.67

Listens on port 80 inside the container and serves the site and PHP handler.

OpenCode

v2.3.0

An AI coding agent in the terminal. Run opencode or use the OpenCode button in the web terminal.

Languages & data

Script, compile and query

Python, Go, C/C++ and SQLite are installed in the same container as the site and terminal.

Python

3.12.13

CPython 3 with pip. Use a virtualenv (python3 -m venv .venv) for installs.

Go

go1.22.10

The full Go toolchain. GOPATH is persisted in a Docker volume.

C / C++

g++ 13.2.1

gcc, g++, make and musl-dev for native builds with no extra setup.

SQLite

3.45.3

The sqlite3 CLI plus PHP pdo_sqlite and sqlite3 extensions.
