Dockerignore

As explained in .NET in Action, Second Edition

.dockerignore is a Docker configuration file that specifies files and directories excluded from a build context.

.dockerignore controls which files and directories Docker excludes from the build context. This prevents local build artifacts from being copied into an image when a Dockerfile copies the current folder. section 13.3.1

Typical .NET exclusions

A .NET service can exclude /bin/, /obj/, and /.vscode/. These directories contain local build or editor artifacts that do not belong in the container image. section 13.3.1

Listing 13.3 Contents of .dockerignore

/bin/
/obj/
  
# Ignore any Visual Studio Code-specific artifacts    #1
/.vscode/

Inspect the complete .dockerignore example for the AsciiArtSvc service. section 13.3.1
