Functions ¶
func ContainsIgnoreCase ¶
ContainsIgnoreCase checks if string s contains substr (case-insensitive) This is a utility function used by frameworks for flexible matching
func DetermineJavaVersion ¶
DetermineJavaVersion determines the major Java version from a Java installation by reading the JAVA_VERSION field from the release file.
Parameters:
- javaHome: Path to the Java installation (e.g., /deps/0/jre)
Returns the major version (8, 11, 17, etc.) or an error if unable to determine.
Example:
version, err := DetermineJavaVersion("/deps/0/jre")
func GetJavaMajorVersion ¶
GetJavaMajorVersion returns the Java major version from the JAVA_HOME environment variable. This is a convenience wrapper around DetermineJavaVersion that reads JAVA_HOME from the environment.
Returns the major version (8, 11, 17, etc.) or an error if JAVA_HOME is not set or the version cannot be determined.
Example:
version, err := GetJavaMajorVersion()
Types ¶
type Context ¶
type Context struct {
Stager Stager
Manifest Manifest
Installer Installer
Log *libbuildpack.Logger
Command Command
}
Context holds shared dependencies for buildpack components Used by containers, frameworks, and JREs to access buildpack infrastructure
type Installer ¶
type Installer interface {
InstallDependency(libbuildpack.Dependency, string) error
InstallDependencyWithStrip(libbuildpack.Dependency, string, int) error
}
type Manifest ¶
type Manifest interface {
AllDependencyVersions(string) []string
DefaultVersion(string) (libbuildpack.Dependency, error)
GetEntry(libbuildpack.Dependency) (*libbuildpack.ManifestEntry, error)
}
type VCAPService ¶
type VCAPService struct {
Name string `json:"name"`
Label string `json:"label"`
Tags []string `json:"tags"`
Credentials map[string]interface{} `json:"credentials"`
}
VCAPService represents a single Cloud Foundry service binding
func (*VCAPService) HasTag ¶
func (s *VCAPService) HasTag(tag string) bool
HasTag checks if this service has the specified tag
type VCAPServices ¶
type VCAPServices map[string][]VCAPService
VCAPServices represents the VCAP_SERVICES environment variable structure This is a map of service labels to arrays of service instances
func GetVCAPServices ¶
func GetVCAPServices() (VCAPServices, error)
GetVCAPServices parses the VCAP_SERVICES environment variable Returns an empty VCAPServices map if VCAP_SERVICES is not set
func (VCAPServices) GetService ¶
func (v VCAPServices) GetService(label string) *VCAPService
GetService returns the first service with the given label Returns nil if no service with the label exists
func (VCAPServices) GetServiceByNamePattern ¶
func (v VCAPServices) GetServiceByNamePattern(pattern string) *VCAPService
GetServiceByNamePattern returns the first service that matches the pattern Returns nil if no matching service is found Pattern matching is case-insensitive substring matching (e.g., "newrelic" matches "my-newrelic-service") Searches across all service labels, not just "user-provided"
func (VCAPServices) HasService ¶
func (v VCAPServices) HasService(label string) bool
HasService checks if a service with the given label exists Matching is case-insensitive to handle various service broker conventions
func (VCAPServices) HasServiceByNamePattern ¶
func (v VCAPServices) HasServiceByNamePattern(pattern string) bool
HasServiceByNamePattern checks if any service matches the pattern Pattern matching is case-insensitive substring matching Searches across all service labels, not just "user-provided"
func (VCAPServices) HasTag ¶
func (v VCAPServices) HasTag(tag string) bool
HasTag checks if any service has the given tag Matching is case-insensitive to handle various service broker tag conventions
type YamlHandler ¶
type YamlHandler struct{}
YamlHandler provides a thin wrapper around yaml.v3's Marshal and Unmarshal.
func (YamlHandler) Marshal ¶
func (h YamlHandler) Marshal(in any) ([]byte, error)
Marshal encodes the given value into YAML.
func (YamlHandler) Unmarshal ¶
func (h YamlHandler) Unmarshal(data []byte, out any) error
Unmarshal decodes the YAML data into the provided destination.
func (YamlHandler) ValidateFields ¶
func (h YamlHandler) ValidateFields(data []byte, out interface{}) error
ValidateFields is used to detect unknown fields during parsing of JBP_CONFIG* configurations
