####################### 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/bitwardenrs/web-vault/tags,
#   click the tag name to view the digest of the image it currently points to.
# - From the command line:
#     $ docker pull bitwardenrs/web-vault:v2.19.0
#     $ docker image inspect --format "{{.RepoDigests}}" bitwardenrs/web-vault:v2.19.0
#     [bitwardenrs/web-vault@sha256:8747cfaa2c6d87d1749e119dd884697e8099389aa9aca30a4d73d4ff796fe0e4]
#
# - Conversely, to get the tag name from the digest:
#     $ docker image inspect --format "{{.RepoTags}}" bitwardenrs/web-vault@sha256:8747cfaa2c6d87d1749e119dd884697e8099389aa9aca30a4d73d4ff796fe0e4
