# This file was generated using a Jinja2 template.
# Please make your changes in `DockerSettings.yaml` or `Dockerfile.j2` and then `make`
# This will generate two Dockerfile's `Dockerfile.debian` and `Dockerfile.alpine`

####################### VAULT BUILD IMAGE #######################
# The web-vault digest specifies a particular web-vault build on Docker Hub.
# Using the digest instead of the tag name provides better security,
# as the digest of an image is immutable, whereas a tag name can later
# be changed to point to a malicious image.
#
# To verify the current digest for a given tag name:
# - From https://hub.docker.com/r/vaultwarden/web-vault/tags,
#   click the tag name to view the digest of the image it currently points to.
# - From the command line:
#     $ docker pull docker.io/vaultwarden/web-vault:{{ vault_version }}
#     $ docker image inspect --format "{{ '{{' }}.RepoDigests}}" docker.io/vaultwarden/web-vault:{{ vault_version }}
#     [docker.io/vaultwarden/web-vault@{{ vault_image_digest }}]
#
# - Conversely, to get the tag name from the digest:
#     $ docker image inspect --format "{{ '{{' }}.RepoTags}}" docker.io/vaultwarden/web-vault@{{ vault_image_digest }}
#     [docker.io/vaultwarden/web-vault:{{ vault_version }}]
#

######################## RUNTIME IMAGE  ########################
# Create a new stage with a minimal image
# because we already have a binary built
#
# To build these images you need to have qemu binfmt support.
# See the following pages to help install these tools locally
# Ubuntu/Debian: https://wiki.debian.org/QemuUserEmulation
# Arch Linux: https://wiki.archlinux.org/title/QEMU#Chrooting_into_arm/arm64_environment_from_x86_64
#
# Or use a Docker image which modifies your host system to support this.
# The GitHub Actions Workflow uses the same image as used below.
# See: https://github.com/tonistiigi/binfmt
# Usage: docker run --privileged --rm tonistiigi/binfmt --install arm64,arm
# To uninstall: docker run --privileged --rm tonistiigi/binfmt --uninstall 'qemu-*'
#
# We need to add `--platform` here, because of a podman bug: https://github.com/containers/buildah/issues/4742
