This is done by running `setcap cap_net_bind_service=+ep` on the executable in the build stage (doing it in the runtime stage creates an extra copy of the executable that bloats the image). This only works when using the BuildKit-based builder, since the `COPY` instruction doesn't copy capabilities on the legacy builder.

####################### 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:v2023.1.1
|
|
# $ docker image inspect --format "{{.RepoDigests}}" vaultwarden/web-vault:v2023.1.1
|
|
# [vaultwarden/web-vault@sha256:d5f71fb05c4b87935bf51d84140db0f8716cabfe2974fbee6c0c5ee8cf7dab5a]
|
|
#
|
|
# - Conversely, to get the tag name from the digest:
|
|
# $ docker image inspect --format "{{.RepoTags}}" vaultwarden/web-vault@sha256:d5f71fb05c4b87935bf51d84140db0f8716cabfe2974fbee6c0c5ee8cf7dab5a
