Dockerfile

Rama main · réplica de lectura del repositorio original.

# This Dockerfile is provided for convenience if you wish to run Phoenix in a
# container or sidecar. To build the image, run the following commmand:
#
# > docker build -t phoenix
#
# You can then run the image in the background with:
#
# > docker run -d --name phoenix -p 6006:6006 phoenix
#
# or in the foreground with:
#
# > docker run -it -p 6006:6006 phoenix
#
# How are you using Phoenix in production? Let us know!
#
# To get support or provide feedback, contact the team in the #phoenix-support

# Bundle the Deno runtime so the local DENO sandbox provider works inside
# the distroless image. denoland/deno:bin-<version> is a scratch-based
# image that contains a single statically-linked /deno binary, which is
# safe to COPY into the distroless final stage without dragging in a
# shell or libc. Pinning the version (NOT :latest) keeps builds
# reproducible.

# Pre-download the CPython WASM binary so the WASM sandbox provider works
# inside the distroless final image without network egress or a writable
# home cache. The URL/filename/sha256 here MUST stay in sync with
# src/phoenix/server/sandbox/_download.py (_WASM_URL / _WASM_FILENAME /
# _WASM_SHA256); the env var PHOENIX_WASM_BINARY_PATH (set in the final
# stage) is the authoritative resolver hook consumed by
# ensure_wasm_binary(). The sha256 assertion guards against upstream
# release-asset tampering — TLS alone is not enough for a binary that
# executes user code in the sandbox.
#
# Its own stage, and it must stay that way: nothing here depends on the
# repo, so the layer is keyed on the URL and digest alone and survives
# every source change. Folded back into backend-builder it would sit below
# COPY ./src and re-download on each commit. Built on UV_IMAGE — the image
# the backend already pulls — for its python, so no apt-get curl layer and
# no second pull.
#
# Retried with backoff: GitHub intermittently closes the connection to this
# asset without sending a response. socket.setdefaulttimeout stands in for
# the timeout argument urlretrieve does not take, and mirrors
# _WASM_DOWNLOAD_TIMEOUT_SECONDS in _download.py. Verification runs inside
# the loop and is the only proof of a complete transfer — urlretrieve
# reports success on a clean close when no Content-Length was received — so
# the loop breaks only on a digest match and no unverified file survives an
# attempt.

#
# > docker run --entrypoint=sh -it phoenix

# pydantic_monty._binary.find_monty_binary). Appended rather than
# prepended because the venv's python/python3/python3.13 symlinks point
# at the builder image's interpreter and dangle here — the system
# interpreter must keep winning any name collision.
