Functions ¶
func IsCurrentStage ¶
IsCurrentStage check if the stage name is the current stage
func IsUnknownInstruction ¶
IsUnknownInstruction checks if the error is an UnknownInstruction or a parseError containing an UnknownInstruction
func Parse ¶
func Parse(ast *parser.Node) (stages []Stage, metaArgs []ArgCommand, err error)
Parse a Dockerfile into a collection of buildable stages. metaArgs is a collection of ARG instructions that occur before the first FROM.
func ParseInstruction ¶
ParseInstruction converts an AST to a typed instruction (either a command or a build stage beginning when encountering a `FROM` statement)
Types ¶
type AddCommand ¶
type AddCommand struct {
SourcesAndDest
Chown string
// contains filtered or unexported fields
}
AddCommand : ADD foo /path
Add the file 'foo' to '/path'. Tarball and Remote URL (http, https) handling exist here. If you do not wish to have this automatic handling, use COPY.
func (*AddCommand) Expand ¶
func (c *AddCommand) Expand(expander SingleWordExpander) error
Expand variables
type ArgCommand ¶
type ArgCommand struct {
KeyValuePairOptional
// contains filtered or unexported fields
}
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'. Dockerfile author may optionally set a default value of this variable.
func (*ArgCommand) Expand ¶
func (c *ArgCommand) Expand(expander SingleWordExpander) error
Expand variables
type BFlags ¶
type BFlags struct {
Args []string // actual flags/args from cmd line
Err error
// contains filtered or unexported fields
}
BFlags contains all flags information for the builder
func NewBFlagsWithArgs ¶
NewBFlagsWithArgs returns the new BFlags struct with Args set to args
func (*BFlags) AddBool ¶
AddBool adds a bool flag to BFlags Note, any error will be generated when Parse() is called (see Parse).
func (*BFlags) AddString ¶
AddString adds a string flag to BFlags Note, any error will be generated when Parse() is called (see Parse).
func (*BFlags) AddStrings ¶
AddStrings adds a string flag to BFlags that can match multiple values
func (*BFlags) Parse ¶
Parse parses and checks if the BFlags is valid. Any error noticed during the AddXXX() funcs will be generated/returned here. We do this because an error during AddXXX() is more like a compile time error so it doesn't matter too much when we stop our processing as long as we do stop it, so this allows the code around AddXXX() to be just:
defFlag := AddString("description", "")
w/o needing to add an if-statement around each one.
type CmdCommand ¶
type CmdCommand struct {
ShellDependantCmdLine
// contains filtered or unexported fields
}
CmdCommand : CMD foo
Set the default command to run in the container (which may be empty). Argument handling is the same as RUN.
type Command ¶
type Command interface {
Name() string
}
Command is implemented by every command present in a dockerfile
type CopyCommand ¶
type CopyCommand struct {
SourcesAndDest
From string
Chown string
// contains filtered or unexported fields
}
CopyCommand : COPY foo /path
Same as 'ADD' but without the tar and remote url handling.
func (*CopyCommand) Expand ¶
func (c *CopyCommand) Expand(expander SingleWordExpander) error
Expand variables
type EntrypointCommand ¶
type EntrypointCommand struct {
ShellDependantCmdLine
// contains filtered or unexported fields
}
EntrypointCommand : ENTRYPOINT /usr/sbin/nginx
Set the entrypoint to /usr/sbin/nginx. Will accept the CMD as the arguments to /usr/sbin/nginx. Uses the default shell if not in JSON format.
Handles command processing similar to CMD and RUN, only req.runConfig.Entrypoint is initialized at newBuilder time instead of through argument parsing.
type EnvCommand ¶
type EnvCommand struct {
Env KeyValuePairs // kvp slice instead of map to preserve ordering
// contains filtered or unexported fields
}
EnvCommand : ENV key1 value1 [keyN valueN...]
func (*EnvCommand) Expand ¶
func (c *EnvCommand) Expand(expander SingleWordExpander) error
Expand variables
type ExposeCommand ¶
type ExposeCommand struct {
Ports []string
// contains filtered or unexported fields
}
ExposeCommand : EXPOSE 6667/tcp 7000/tcp
Expose ports for links and port mappings. This all ends up in req.runConfig.ExposedPorts for runconfig.
type HealthCheckCommand ¶
type HealthCheckCommand struct {
Health *container.HealthConfig
// contains filtered or unexported fields
}
HealthCheckCommand : HEALTHCHECK foo
Set the default healthcheck command to run in the container (which may be empty). Argument handling is the same as RUN.
type KeyValuePair ¶
KeyValuePair represent an arbitrary named value (useful in slice instead of map[string] string to preserve ordering)
func (*KeyValuePair) String ¶
func (kvp *KeyValuePair) String() string
type KeyValuePairOptional ¶
KeyValuePairOptional is the same as KeyValuePair but Value is optional
func (*KeyValuePairOptional) ValueString ¶
func (kvpo *KeyValuePairOptional) ValueString() string
type LabelCommand ¶
type LabelCommand struct {
Labels KeyValuePairs // kvp slice instead of map to preserve ordering
// contains filtered or unexported fields
}
LabelCommand : LABEL some json data describing the image
Sets the Label variable foo to bar,
func NewLabelCommand ¶
func NewLabelCommand(k string, v string, NoExp bool) *LabelCommand
NewLabelCommand creates a new 'LABEL' command
func (*LabelCommand) Expand ¶
func (c *LabelCommand) Expand(expander SingleWordExpander) error
Expand variables
type MaintainerCommand ¶
type MaintainerCommand struct {
Maintainer string
// contains filtered or unexported fields
}
MaintainerCommand : MAINTAINER maintainer_name
type OnbuildCommand ¶

type RunCommand ¶
type RunCommand struct {
ShellDependantCmdLine
// contains filtered or unexported fields
}
RunCommand : RUN some command yo
run a command and commit the image. Args are automatically prepended with the current SHELL which defaults to 'sh -c' under linux or 'cmd /S /C' under Windows, in the event there is only one argument The difference in processing:
RUN echo hi # sh -c echo hi (Linux) RUN echo hi # cmd /S /C echo hi (Windows) RUN [ "echo", "hi" ] # echo hi
