# syntax=docker/dockerfile:1
# This file was generated using a Jinja2 template.
# Please make your changes in `Dockerfile.j2` and then `make` the individual Dockerfiles.
# Using multistage build:
# https://docs.docker.com/develop/develop-images/multistage-build/

####################### 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 vaultwarden/web-vault:v2.25.1b
# $ docker image inspect --format "{{.RepoDigests}}" vaultwarden/web-vault:v2.25.1b
# [vaultwarden/web-vault@sha256:9b82318d553d72f091e8755f5aff80eed495f90bbe5b0703522953480f5c2fba]
#
# - Conversely, to get the tag name from the digest:
# $ docker image inspect --format "{{.RepoTags}}" vaultwarden/web-vault@sha256:9b82318d553d72f091e8755f5aff80eed495f90bbe5b0703522953480f5c2fba
