説明
(From the #skaffold Slack channel)
Buildkit supports run --mount=type=bind,source=xxx,target=yyy which behaves similar to a COPY xxx yyy. The type=bind can be omitted as this is the default mount type.
The doc does say that this is only valid with dockerfile syntax 1.2 or above:
To use this flag set Dockerfile version to at least 1.2
# syntax=docker/dockerfile:1.2
Expected behavior
Skaffold would detect changes to the source in xxx and trigger a rebuild.
Actual behavior
Skaffold doesn't detect the source changes.
Information
- Skaffold version: unspecified
Workaround
Insert manual COPY statements.
