Functions

func ConvertToModel

func ConvertToModel(cfg DeclarativeConfig) (model.Model, error)

func WalkFS

func WalkFS(root fs.FS, walkFn WalkFunc) error

WalkFS walks root using a gitignore-style filename matcher to skip files that match patterns found in .indexignore files found throughout the filesystem. It calls walkFn for each declarative config file it finds. If WalkFS encounters an error loading or parsing any file, the error will be immediately returned.

func WriteJSON

func WriteJSON(cfg DeclarativeConfig, w io.Writer) error

func WriteMermaidChannels

func WriteMermaidChannels(cfg DeclarativeConfig, out io.Writer, minEdgeName string) error

writes out the channel edges of the declarative config graph in a mermaid format capable of being pasted into mermaid renderers like github, mermaid.live, etc. output is sorted lexicographically by package name, and then by channel name if provided, minEdgeName will be used as the lower bound for edges in the output graph

NB: Output has wrapper comments stating the skipRange edge caveat in HTML comment format, which cannot be parsed by mermaid renderers.

This is deliberate, and intended as an explicit acknowledgement of the limitations, instead of requiring the user to notice the missing edges upon inspection.

Example output: <!-- PLEASE NOTE: skipRange edges are not currently displayed --> graph LR

  %% package "neuvector-certified-operator-rhmp"
  subgraph "neuvector-certified-operator-rhmp"
     %% channel "beta"
     subgraph neuvector-certified-operator-rhmp-beta["beta"]
	      neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.2.8["neuvector-operator.v1.2.8"]
	      neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.2.9["neuvector-operator.v1.2.9"]
	      neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.3.0["neuvector-operator.v1.3.0"]
	      neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.3.0["neuvector-operator.v1.3.0"]-- replaces --> neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.2.8["neuvector-operator.v1.2.8"]
	      neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.3.0["neuvector-operator.v1.3.0"]-- skips --> neuvector-certified-operator-rhmp-beta-neuvector-operator.v1.2.9["neuvector-operator.v1.2.9"]
    end

end <!-- PLEASE NOTE: skipRange edges are not currently displayed -->

func WriteYAML

Types

type Bundle

type Bundle struct {
	Schema        string              `json:"schema"`
	Name          string              `json:"name"`
	Package       string              `json:"package"`
	Image         string              `json:"image"`
	Properties    []property.Property `json:"properties,omitempty" hash:"set"`
	RelatedImages []RelatedImage      `json:"relatedImages,omitempty" hash:"set"`

	// These fields are present so that we can continue serving
	// the GRPC API the way packageserver expects us to in a
	// backwards-compatible way. These are populated from
	// any `olm.bundle.object` properties.
	//
	// These fields will never be persisted in the bundle blob as
	// first class fields.
	CsvJSON string   `json:"-"`
	Objects []string `json:"-"`
}

Bundle specifies all metadata and data of a bundle object. Top-level fields are the source of truth, i.e. not CSV values.

Notes:

• Any field slice type field or type containing a slice somewhere where two types/fields are equal if their contents are equal regardless of order must have a `hash:"set"` field tag for bundle comparison.
• Any fields that have a `json:"-"` tag must be included in the equality evaluation in bundlesEqual().

type Channel

type Channel struct {
	Schema     string              `json:"schema"`
	Name       string              `json:"name"`
	Package    string              `json:"package"`
	Entries    []ChannelEntry      `json:"entries"`
	Properties []property.Property `json:"properties,omitempty" hash:"set"`
}

type ChannelEntry

type ChannelEntry struct {
	Name      string   `json:"name"`
	Replaces  string   `json:"replaces,omitempty"`
	Skips     []string `json:"skips,omitempty"`
	SkipRange string   `json:"skipRange,omitempty"`
}

type DeclarativeConfig

type DeclarativeConfig struct {
	Packages []Package
	Channels []Channel
	Bundles  []Bundle
	Others   []Meta
}

func ConvertFromModel

func ConvertFromModel(mpkgs model.Model) DeclarativeConfig

func LoadFS

func LoadFS(root fs.FS) (*DeclarativeConfig, error)

LoadFS loads a declarative config from the provided root FS. LoadFS walks the filesystem from root and uses a gitignore-style filename matcher to skip files that match patterns found in .indexignore files found throughout the filesystem. If LoadFS encounters an error loading or parsing any file, the error will be immediately returned.

func LoadFile

func LoadFile(root fs.FS, path string) (*DeclarativeConfig, error)

LoadFile will unmarshall declarative config components from a single filename provided in 'path' located at a filesystem hierarchy 'root'

	DefaultChannel string              `json:"defaultChannel"`
