# Since 0.30.0 release Git is supported and required as a dependency.
# NOTE: @asyncapi/studio is no longer a hard dependency of the CLI, so it is not
# present in this image (keeps it ~450MB smaller). `asyncapi start studio`,
# `start preview` and `new --studio` will offer to install Studio on-demand into
# the container's data directory (pass `--yes` or ASYNCAPI_STUDIO_AUTO_INSTALL=1
# in non-interactive contexts). Chromium is kept so that html-template PDF
# generation works out of the box.
# More custom packages for specific templates should not be added to this
# dockerfile. Instead, we should come up with some extensibility solution.
