Functions ¶
func IsTemplateFile ¶
IsTemplateFile returns true if filename points to a valid template file; otherwise returns false.
func PackageRunManifestGeneral ¶ added in v0.2.0
PackageRunManifestGeneral parses meta/run.yaml file into blank RunConfig. By 'blank' we mean that the struct has no fields populated, but it is of correct type i.e. appropriate implementation of Runtime interface. NOTE: We must differentiate two things regarding Runtime interface implementation:
a) what struct is it implemented with -> e.g. nodeJsRuntime b) what fields is struct populated with -> e.g. nodeJsRuntime.Main For a given meta/run.yaml all config sets get the same (a), but are populated with different values for (b).
NOTE: when Capstan needs to know what packages to require, it needs (a), but
not (b). And this function returns exactly this, (a) without (b).
Types ¶
type CmdConfig ¶ added in v0.2.0
type CmdConfig struct {
RuntimeType runtime.RuntimeType
ConfigSetDefault string
// ConfigSets is a map of available <config-name>:<runtime> pairs.
// The map is built based on meta/run.yaml.
ConfigSets map[string]runtime.Runtime
}
CmdConfig is a result that parsing meta/run.yaml yields.
func ParsePackageRunManifestData ¶ added in v0.2.0
ParsePackageRunManifestData returns parsed manifest data.
type HashCache ¶ added in v0.2.0
func NewHashCache ¶ added in v0.2.0
func NewHashCache() HashCache
func ParseHashCache ¶ added in v0.2.0
ParseHashCache looks for a file at given location and tries to parse the HashCache config. In case the file does not exist or is not a valid HashCache file, it fails with an error.
func (*HashCache) WriteToFile ¶ added in v0.2.0
type Package ¶ added in v0.2.0
type Package struct {
Name string
Title string
Author string "author,omitempty"
Version string "version,omitempty"
Require []string "require,omitempty"
Binary map[string]string "binary,omitempty"
// ModTime is currently used only for setting the modification time of local
// packages. It is ignored by the YAML parser.
ModTime time.Time "-"
}
func ParsePackageManifest ¶ added in v0.2.0
type RpmPackage ¶
func (*RpmPackage) Download ¶
func (p *RpmPackage) Download() error
func (*RpmPackage) Filename ¶
func (p *RpmPackage) Filename() string
func (*RpmPackage) URL ¶
func (p *RpmPackage) URL() string
type Template ¶
type Template struct {
Base string
RpmBase *RpmPackage "rpm-base"
Cmdline string
Build string
Files map[string]string
Rootfs string
}
A template is a configuration file that describes how to build a VM image. It is usually representeed as a `Capstanfile` file on disk.
func ParseTemplate ¶
