From 7150736688414d92ac6a04605145a9744b080a03 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Sat, 24 Oct 2020 01:03:47 +0200 Subject: [PATCH] Deprecation: add experimental docker build --stream option Docker v17.07 introduced an experimental `--stream` flag on `docker build` which allowed the build-context to be incrementally sent to the daemon, instead of unconditionally sending the whole build-context. This functionality has been reimplemented as part of BuildKit, which uses streaming by default and the `--stream` option will be ignored when using the classic builder, printing a deprecation warning instead. Users that want to use this feature are encouraged to enable BuildKit by setting the `DOCKER_BUILDKIT=1` environment variable or through the daemon or CLI configuration files.
