Types ¶
type BuildHistory ¶
type BuildHistory struct { DefinitionHash string `json:"definitionHash"` Definition `json:"definition"` Parent *BuildHistory `json:"parent"` }
BuildHistory ...
type Bundle ¶
type Bundle struct { // FSObjects is a map of the filesystem objects contained in the Bundle. An object // will be built as one section of a SIF file. // // Known FSObjects labels: // * rootfs -> root file system // * .singularity.d -> .singularity.d directory (includes image exec scripts) // * data -> directory containing data files FSObjects map[string]string `json:"fsObjects"` JSONObjects map[string][]byte `json:"jsonObjects"` Recipe Definition `json:"rawDeffile"` BindPath []string `json:"bindPath"` Path string `json:"bundlePath"` Opts Options `json:"opts"` }
Bundle is the temporary build environment used during the image building process. A Bundle is the programmatic representation of the directory structure which will constitute this environmenb. /tmp/...:
fs/ - A chroot filesystem .singularity.d/ - Container metadata (from 2.x image format) config.json (optional) - Contain information for OCI image bundle etc... - The Bundle dir can theoretically contain arbitrary directories, files, etc... which can be interpreted by the Chef
func (Bundle) RunSection ¶
RunSection iterates through the sections specified in a bundle and returns true if the given string, s, is a section of the definition that should be executed during the build process
type Data ¶
type Data struct { Files []FileTransport `json:"files"` Scripts `json:"buildScripts"` }
Data contains any scripts, metadata, etc... that the Builder may need to know only at build time to build the image
type Definition ¶
type Definition struct { Header map[string]string `json:"header"` ImageData `json:"imageData"` BuildData Data `json:"buildData"` CustomData map[string]string `json:"customData"` Raw []byte `json:"raw"` }
Definition describes how to build an image.
func NewDefinitionFromJSON ¶
func NewDefinitionFromJSON(r io.Reader) (d Definition, err error)
NewDefinitionFromJSON creates a new Definition using the supplied JSON.
func NewDefinitionFromURI ¶
func NewDefinitionFromURI(uri string) (d Definition, err error)
NewDefinitionFromURI crafts a new Definition given a URI
type FileTransport ¶
FileTransport holds source and destination information of files to copy into the container
type ImageData ¶
type ImageData struct { Metadata []byte `json:"metadata"` Labels map[string]string `json:"labels"` ImageScripts `json:"imageScripts"` }
ImageData contains any scripts, metadata, etc... that needs to be present in some from in the final built image
type ImageScripts ¶
type ImageScripts struct { Help string `json:"help"` Environment string `json:"environment"` Runscript string `json:"runScript"` Test string `json:"test"` Startscript string `json:"startScript"` }
ImageScripts contains scripts that are used after build time.
type MetaData ¶
type MetaData struct { // DefaultCommand is the process which should be executed by default when calling // "singularity run ... " DefaultCommand string `json:"defaultCommand"` // Overridable sets whether or not the user supplied arguments to "singularity run ..." // can override the default Command. Overridable bool `json:"overridable"` // DefaultArgs are the default arguments passed to the Command to run in the Container. These // can *always* be overridden by arguments given to "singularity run ..." DefaultArgs string `json:"defaultArgs"` // BaseEnv provides the base environment variables of the container. BaseEnv []string `json:"baseEnv"` BuildHistory *BuildHistory `json:"buildHistory"` }
MetaData ...
type Options ¶
type Options struct { // TmpDir specifies a non-standard temporary location to perform a build TmpDir string // sections are the parts of the definition to run during the build Sections []string `json:"sections"` // noTest indicates if build should skip running the test script NoTest bool `json:"noTest"` // force automatically deletes an existing container at build destination while performing build Force bool `json:"force"` // update detects and builds using an existing sandbox container at build destination Update bool `json:"update"` // noHTTPS NoHTTPS bool `json:"noHTTPS"` // contains docker credentials if specified DockerAuthConfig *ocitypes.DockerAuthConfig // NoCleanUp allows a user to prevent a bundle from being cleaned up after a failed build // useful for debugging NoCleanUp bool `json:"noCleanUp"` }
Options ...
type RequestData ¶
type RequestData struct { Definition `json:"definition"` LibraryRef string `json:"libraryRef"` LibraryURL string `json:"libraryURL"` CallbackURL string `json:"callbackURL"` }
RequestData contains the info necessary for submitting a build to a remote service
type ResponseData ¶
type ResponseData struct { ID bson.ObjectId `json:"id"` CreatedBy string `json:"createdBy"` SubmitTime time.Time `json:"submitTime"` StartTime *time.Time `json:"startTime,omitempty" bson:",omitempty"` IsComplete bool `json:"isComplete"` CompleteTime *time.Time `json:"completeTime,omitempty"` ImageSize int64 `json:"imageSize,omitempty"` ImageChecksum string `json:"imageChecksum,omitempty"` Definition Definition `json:"definition"` WSURL string `json:"wsURL,omitempty" bson:"-"` LibraryRef string `json:"libraryRef"` LibraryURL string `json:"libraryURL"` CallbackURL string `json:"callbackURL"` }
ResponseData contains the details of an individual build
