# Base image which includes all* dependencies checked by ./mach configure.

#

# * Actually not all dependencies. WASM sandboxed depencies were left out for now.

# This installs all dependencies checked by `./mach configure --without-wasm-sandboxed-libraries`.

#

# # Building and publishing

#

# Whenever this file changes, the updated Docker image must be built and published _manually_ to

# the tor-browser container registry (https://gitlab.torproject.org/tpo/applications/tor-browser/container_registry/185).

#

# This image copies a script from the taskcluster/ folder, which requires it

# to be built from a folder which is a parent of the taskcluster/ folder.

#

# To build, run:

#

# ```bash

# docker build \

#   -f <PATH_TO_DOCKERFILE> \

#   -t <REGISTRY_URL>/<IMAGE_NAME>:<IMAGE_TAG>

#   .

# ```

#

# For example, when building from the root of this repository to the main tor-browser repository

# and assuming image name to be "base" and tag "latest" -- which is the current terminology:

#

# ```bash

# docker build \

#   -f .gitlab/ci/docker/Dockerfile \

#   -t containers.torproject.org/tpo/applications/tor-browser/base:latest

#   .
