####################### 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:v2023.7.1
#     $ docker image inspect --format "{{.RepoDigests}}" docker.io/vaultwarden/web-vault:v2023.7.1
#     [docker.io/vaultwarden/web-vault@sha256:b306f38fe0d54fa3d79059a737f8e1803da44ddc5f273c2aecdd6a4886211b0f]
#
# - Conversely, to get the tag name from the digest:
#     $ docker image inspect --format "{{.RepoTags}}" docker.io/vaultwarden/web-vault@sha256:b306f38fe0d54fa3d79059a737f8e1803da44ddc5f273c2aecdd6a4886211b0f
