From c3990f3ba6cb0bdc831279dbce2fa0ce94d07644 Mon Sep 17 00:00:00 2001 From: Tibor Vass Date: Tue, 24 Sep 2019 21:24:46 +0000 Subject: [PATCH] build: remove --stream --stream was always experimental and this patch removes the functionality. Users should enable BuildKit with DOCKER_BUILDKIT=1 Signed-off-by: Tibor Vass --- cli/command/image/build.go | 65 ++-------------------- cli/command/image/build_session.go | 89 ------------------------------ contrib/completion/bash/docker | 5 -- 3 files changed, 5 insertions(+), 154 deletions(-) diff --git a/cli/command/image/build.go b/cli/command/image/build.go index ef50a29179..de2e357b76 100644 --- a/cli/command/image/build.go +++ b/cli/command/image/build.go @@ -10,7 +10,6 @@ import ( "fmt" "io" "io/ioutil" - "net" "os" "path/filepath" "regexp" @@ -33,7 +32,6 @@ import ( "github.com/docker/docker/pkg/urlutil" units "github.com/docker/go-units" "github.com/pkg/errors" - "github.com/sirupsen/logrus" "github.com/spf13/cobra" ) @@ -165,9 +163,7 @@ func NewBuildCommand(dockerCli command.Cli) *cobra.Command { flags.SetAnnotation("squash", "version", []string{"1.25"}) flags.BoolVar(&options.stream, "stream", false, "Stream attaches to server to negotiate build context") - flags.SetAnnotation("stream", "experimental", nil) - flags.SetAnnotation("stream", "version", []string{"1.31"}) - flags.SetAnnotation("stream", "no-buildkit", nil) + flags.MarkHidden("stream") flags.StringVar(&options.progress, "progress", "auto", "Set type of progress output (auto, plain, tty).
