Overview

Package credentials provides primitives for working with Porter credential sets, usually refered to as "credentials" as a shorthand.

Credential Sets define mappings from a credential needed by a bundle to where to look for it when the bundle is run. For example: Bundle needs Azure storage connection string and it should look for it in an environment variable named `AZURE_STORATE_CONNECTION_STRING` or a key named `dev-conn`.

Porter discourages storing the value of the credential directly, though it it is possible. Instead Porter encourages the best practice of defining mappings in the credential sets, and then storing the values in secret stores such as a key/value store like Hashicorp Vault, or Azure Key Vault. See the get.porter.sh/porter/pkg/secrets package for more on how Porter handles accessing secrets.

Constants

)

Functions

func Validate

func Validate(given secrets.Set, spec map[string]bundle.Credential, action string) error

Validate compares the given credentials with the spec.

This will result in an error only when the following conditions are true: - a credential in the spec is not present in the given set - the credential is required - the credential applies to the specified action

It is allowed for spec to specify both an env var and a file. In such case, if the given set provides either, it will be considered valid.

Types

type CredentialSet

type CredentialSet struct {
	// SchemaVersion is the version of the credential-set schema.
	SchemaVersion schema.Version `json:"schemaVersion" yaml:"schemaVersion" toml:"schemaVersion"`

	// Namespace to which the credential set is scoped.
	Namespace string `json:"namespace" yaml:"namespace" toml:"namespace"`

	// Name of the credential set.
	Name string `json:"name" yaml:"name" toml:"name"`

	// Created timestamp.
	Created time.Time `json:"created" yaml:"created" toml:"created"`

	// Modified timestamp.
	Modified time.Time `json:"modified" yaml:"modified" toml:"modified"`

	// Labels applied to the credential set.
	Labels map[string]string `json:"labels,omitempty" yaml:"labels,omitempty" toml:"labels,omitempty"`

	// Credentials is a list of credential resolution strategies.
	Credentials []secrets.Strategy `json:"credentials" yaml:"credentials" toml:"credentials"`
}

CredentialSet represents a collection of credentials

func NewCredentialSet

func NewCredentialSet(namespace string, name string, creds ...secrets.Strategy) CredentialSet

NewCredentialSet creates a new CredentialSet with the required fields initialized.

func (CredentialSet) DefaultDocumentFilter

func (s CredentialSet) DefaultDocumentFilter() interface{}

func (CredentialSet) String

func (s CredentialSet) String() string

func (CredentialSet) Validate

func (s CredentialSet) Validate() error

type CredentialStore

type CredentialStore struct {
	Documents storage.Store
	Secrets   secrets.Store
}

CredentialStore provides access to credential sets by instantiating plugins that implement CRUD storage.

func NewCredentialStore

func NewCredentialStore(storage storage.Store, secrets secrets.Store) *CredentialStore

func (CredentialStore) GetCredentialSet

func (s CredentialStore) GetCredentialSet(namespace string, name string) (CredentialSet, error)

func (CredentialStore) GetDataStore

func (s CredentialStore) GetDataStore() storage.Store

func (CredentialStore) Initialize

func (s CredentialStore) Initialize() error

Initialize the underlying storage with any additional schema changes, such as indexes.

func (CredentialStore) InsertCredentialSet

func (s CredentialStore) InsertCredentialSet(cset CredentialSet) error

func (CredentialStore) ListCredentialSets

func (s CredentialStore) ListCredentialSets(namespace string, name string, labels map[string]string) ([]CredentialSet, error)
