CurrentStage return the last stage in a slice.

HasStage looks for the presence of a given stage name.

IsCurrentStage check if the stage name is the current stage.

IsUnknownInstruction checks if the error is an UnknownInstruction or a parseError containing an UnknownInstruction.

NewBFlags returns the new BFlags struct.

NewBFlagsWithArgs returns the new BFlags struct with Args set to args.

Parse a docker file into a collection of buildable stages.

ParseCommand converts an AST to a typed Command.

ParseInstruction converts an AST to a typed instruction (either a command or a build stage beginning when encountering a `FROM` statement).

AddCommand : ADD foo /path Add the file 'foo' to '/path'.

ArgCommand : ARG name[=value] Adds the variable foo to the trusted list of variables that can be passed to builder using the --build-arg flag for expansion/substitution or passing to 'run'.

BFlags contains all flags information for the builder.

CmdCommand : CMD foo Set the default command to run in the container (which may be empty).

CopyCommand : COPY foo /path Same as 'ADD' but without the tar and remote url handling.

EntrypointCommand : ENTRYPOINT /usr/sbin/nginx Set the entrypoint to /usr/sbin/nginx.

EnvCommand : ENV key1 value1 [keyN valueN...].

ExposeCommand : EXPOSE 6667/tcp 7000/tcp Expose ports for links and port mappings.

Flag contains all information for a flag.

HealthCheckCommand : HEALTHCHECK foo Set the default healthcheck command to run in the container (which may be empty).

KeyValuePair represent an arbitrary named value (useful in slice insted of map[string] string to preserve ordering).

LabelCommand : LABEL some json data describing the image Sets the Label variable foo to bar, .

MaintainerCommand : MAINTAINER maintainer_name.

OnbuildCommand : ONBUILD <some other command>.

RunCommand : RUN some command yo run a command and commit the image.

ShellCommand : SHELL powershell -command Set the non-default shell to use.

ShellDependantCmdLine represents a cmdline optionaly prepended with the shell.

Stage represents a single stage in a multi-stage build.

StopSignalCommand : STOPSIGNAL signal Set the signal that will be used to kill the container.

UnknownInstruction represents an error occurring when a command is unresolvable.

UserCommand : USER foo Set the user to 'foo' for future commands and when running the ENTRYPOINT/CMD at container run time.

VolumeCommand : VOLUME /foo Expose the volume /foo for use.

WorkdirCommand : WORKDIR /tmp Set the working directory for future RUN/CMD/etc statements.

Command is implemented by every command present in a dockerfile.

PlatformSpecific adds platform checks to a command.

SupportsSingleWordExpansion interface marks a command as supporting variable expansion.

FlagType is the type of the build flag.

KeyValuePairs is a slice of KeyValuePair.

SingleWordExpander is a provider for variable expansion where 1 word => 1 output.

SourcesAndDest represent a list of source files and a destination.
