Description

Start a debug session using the debug adapter protocol to communicate with the debugger UI.

Arguments are the same as the build

Examples

Launch request arguments

The following launch request arguments are supported. These are sent as a JSON body as part of the launch request.

Name	Type	Default	Description
dockerfile	string	Dockerfile	Name of the Dockerfile
contextPath	string	.	Set the context path for the build (normally the first positional argument)
target	string		Set the target build stage to build
stopOnEntry	boolean	false	Stop on the first instruction

Additional Arguments

Command line arguments may be passed to the debug adapter the same way they would be passed to the normal build command and they will set the value. Launch request arguments that are set will override command line arguments if they are present.

A debug extension should include an args and builder entry in the launch configuration. These will modify the arguments passed to the binary for the tool invocation. builder will add --builder <arg> directly after the executable and args will append to the end of the tool invocation. For example, a launch configuration in Visual Studio Code with the following:

{
    "args": ["--build-arg", "FOO=AAA"]
    "builder": ["mybuilder"]
}

This should cause the debug adapter to be invoked as docker buildx --builder mybuilder dap build --build-arg FOO=AAA.
