From 5e1e13c18c22e2cd43021cb647eda328324f6c96 Mon Sep 17 00:00:00 2001 From: cdoern Date: Tue, 15 Mar 2022 12:13:41 -0400 Subject: add contextDir to tar on remote podman build fails on remote build when using a relative context directory. This is because the context dir was not being added to the tar, so when remote the compat build function would not be able to stat the contextDir. resolves #13293 Signed-off-by: cdoern --- pkg/bindings/images/build.go | 26 +++++++++++++++++++------- 1 file changed, 19 insertions(+), 7 deletions(-) (limited to 'pkg/bindings') diff --git a/pkg/bindings/images/build.go b/pkg/bindings/images/build.go index c508cb767..1ed3f19de 100644 --- a/pkg/bindings/images/build.go +++ b/pkg/bindings/images/build.go @@ -241,7 +241,9 @@ func Build(ctx context.Context, containerFiles []string, options entities.BuildO params.Add("platform", platform) } } - if contextDir, err := filepath.EvalSymlinks(options.ContextDirectory); err == nil { + var err error + var contextDir string + if contextDir, err = filepath.EvalSymlinks(options.ContextDirectory); err == nil { options.ContextDirectory = contextDir } @@ -301,7 +303,6 @@ func Build(ctx context.Context, containerFiles []string, options entities.BuildO var ( headers http.Header - err error ) if options.SystemContext != nil && options.SystemContext.DockerAuthConfig != nil { headers, err = auth.MakeXRegistryAuthHeader(options.SystemContext, options.SystemContext.DockerAuthConfig.Username, options.SystemContext.DockerAuthConfig.Password) @@ -325,7 +326,7 @@ func Build(ctx context.Context, containerFiles []string, options entities.BuildO } } - contextDir, err := filepath.Abs(options.ContextDirectory) + contextDir, err = filepath.Abs(options.ContextDirectory) if err != nil { logrus.Errorf("Cannot find absolute path of %v: %v", options.ContextDirectory, err) return nil, err @@ -556,16 +557,27 @@ func nTar(excludes []string, sources ...string) (io.ReadCloser, error) { merr = multierror.Append(merr, err) return } - err = filepath.Walk(s, func(path string, info os.FileInfo, err error) error { if err != nil { return err } - if path == s { - return nil // skip root dir + // check if what we are given is an empty dir, if so then continue w/ it.
