# The logic for content trust is a bit convoluted because:
|
|
# - The arm64 base image is currently not signed so we need to pull it
|
|
# with content trust disabled. This is controlled by
|
|
# DOCKER_CONTENT_PULL.
|
|
# - 'docker build' with the FROM image supplied as environment
|
|
# variable *and* with DOCKER_CONTENT_TRUST=1 currently does not work
|
|
# (https://github.com/moby/moby/issues/34199). We therefor build
|
|
# with DOCKER_CONTENT_TRUST explicitly set to 0. However, we pull
|
|
# the base image just before with content trust enabled (if
|
|
# supported, see above).
|
|
# - By default we always pull and push the linuxkit/alpine image with
|
|
# content trust, unless explicitly disabled with NOTRUST. Once the
|
|
# above issues are resolved, this will be the only mechanism to control
|
|
# content trust.
