# solis-session-php — test and demo container.
#
# Two targets:
#
#   test  (default) — installs the dev dependencies and runs PHPUnit.
#   demo            — serves a small page that exercises the library against a
#                     running solis-identity, with NO Composer install at all,
#                     which also proves the package's zero-runtime-dependency
#                     claim: src/ on disk plus ext-openssl is the whole story.
#
# Run the suite:
#   docker build -t solis-session-php . && docker run --rm solis-session-php
#
# Check another PHP version (the package supports >= 8.1):
#   docker build --build-arg PHP_VERSION=8.1 -t solis-session-php:8.1 .
#
# Interactive demo — see compose.yaml, or:
#   docker build --target demo -t solis-session-php:demo .
#   docker run --rm -p 8080:8080 \
#     -e SOLIS_IDENTITY_BASE=http://localhost:4567 \
#     -e SOLIS_IDENTITY_INTERNAL=http://host.docker.internal:4567 \
#     -e SOLIS_TENANT=acme -e SOLIS_APP=intranet \
#     solis-session-php:demo
