####################### VAULT BUILD IMAGE  #######################

#  This hash is extracted from the docker web-vault builds and it's preferred over a simple tag because it's immutable.
#  It can be viewed in multiple ways:
#  - From the https://hub.docker.com/repository/docker/bitwardenrs/web-vault/tags page, click the tag name and the digest should be there.
#  - From the console, with the following commands:
#      docker pull bitwardenrs/web-vault:v2.17.1
#      docker image inspect --format "{{.RepoDigests}}" bitwardenrs/web-vault:v2.17.1
#
#  - To do the opposite, and get the tag from the hash, you can do:
#      docker image inspect --format "{{.RepoTags}}" bitwardenrs/web-vault@sha256:dcb7884dc5845b3842ff2204fe77482000b771495c6c359297ec3c03330d65e0
