var ErrMultipleDetectedCredentials = errors.New("multiple detected credentials")

ErrMultipleDetectedCredentials is the error returned by GetOrDetectCredential when multiple credentials are detected, meaning Juju cannot choose one automatically.

var ErrNoAuthorizedKeys = errors.New("no public ssh keys found")

func BootstrapEndpointAddresses Uses

func BootstrapEndpointAddresses(
    environ environs.InstanceBroker, callContext context.ProviderCallContext,
) ([]network.ProviderAddress, error)

BootstrapEndpointAddresses returns the addresses of the bootstrapped instance.

func BuiltInClouds Uses

func BuiltInClouds() (map[string]jujucloud.Cloud, error)

BuiltInClouds returns cloud information for those providers which are built in to Juju.

func ChooseCloudRegion Uses

func ChooseCloudRegion(cloud jujucloud.Cloud, regionName string) (jujucloud.Region, error)

ChooseCloudRegion returns the cloud.Region to use, based on the specified region name. If no region name is specified, and there is at least one region, we use the first region in the list. If there are no regions, then we return a region with no name, having the same endpoints as the cloud.

func CloudByName Uses

func CloudByName(cloudName string) (*jujucloud.Cloud, error)

CloudByName returns a cloud for given name regardless of whether it's public, private or builtin cloud. Not to be confused with cloud.CloudByName which does not cater for built-in clouds like localhost.

func CloudOrProvider Uses

func CloudOrProvider(cloudName string, cloudByNameFunc func(string) (*jujucloud.Cloud, error)) (cloud *jujucloud.Cloud, err error)

CloudOrProvider finds and returns cloud or provider.

func CloudSchemaByType Uses

func CloudSchemaByType(cloudType string) (environschema.Fields, error)

CloudSchemaByType returns the Schema for a given cloud type. If the ProviderSchema is not implemented for the given cloud type, a NotFound error is returned.

func ConformYAML Uses

func ConformYAML(input interface{}) (interface{}, error)

ConformYAML ensures all keys of any nested maps are strings. This is necessary because YAML unmarshals map[interface{}]interface{} in nested maps, which cannot be serialized by bson. Also, handle []interface{}. cf. gopkg.in/juju/charm.v4/actions.go cleanse

func FinalizeAuthorizedKeys Uses

func FinalizeAuthorizedKeys(ctx *cmd.Context, attrs map[string]interface{}) error

FinalizeAuthorizedKeys takes a set of configuration attributes and ensures that it has an authorized-keys setting, or returns ErrNoAuthorizedKeys if it cannot.

If the attributes contains a non-empty value for "authorized-keys", then it is left alone. If there is an "authorized-keys-path" setting, its contents will be loaded into "authorized-keys". Otherwise, the contents of standard public keys will be used: ~/.ssh/id_dsa.pub, ~/.ssh/id_rsa.pub, and ~/.ssh/identity.pub.

func FormatConfigSchema Uses

func FormatConfigSchema(values interface{}) (string, error)

func FormatTime Uses

func FormatTime(t *time.Time, formatISO bool) string

func FormatTimeAsTimestamp Uses

func FormatTimeAsTimestamp(t *time.Time, formatISO bool) string

FormatTimeAsTimestamp formats a time.Time to a given machine readable format. Returns a string with the local time formatted or uses the localized tz or in UTC timezone. The difference between this and `common.FormatTime` is that this version drops the date part of the time.Time.

func FriendlyDuration Uses

func FriendlyDuration(when *time.Time, now time.Time) string

FriendlyDuration renders a time pointer that we get from the API as a friendly string.

func GUIDataSourceBaseURL Uses

func GUIDataSourceBaseURL() string

func GetOrDetectCredential Uses

func GetOrDetectCredential(
    ctx *cmd.Context,
    store jujuclient.CredentialGetter,
    provider environs.EnvironProvider,
    args modelcmd.GetCredentialsParams,
) (_ *jujucloud.Credential, chosenCredentialName, regionName string, isDetected bool, returnedErr error)

GetOrDetectCredential returns a credential to use for given cloud. This function first calls modelcmd.GetCredentials, and returns its results if it finds credentials. If modelcmd.GetCredentials cannot find a credential, and a credential has not been specified by name, then this function will attempt to detect credentials from the environment.

If multiple credentials are found in the client store, then modelcmd.ErrMultipleCredentials is returned. If multiple credentials are detected by the provider, then ErrMultipleDetectedCredentials is returned.

func HumanReadableBoolPointer Uses

func HumanReadableBoolPointer(pointer *bool, trueValue, falseValue string) string

HumanReadableBoolPointer returns trueValue if given bool pointer contains true, falseValue otherwise.

func MaybeTermsAgreementError Uses

func MaybeTermsAgreementError(err error) error

MaybeTermsAgreementError returns err as a *TermsAgreementError if it has a "terms agreement required" error code, otherwise it returns err unchanged.

func MissingModelNameError Uses

func MissingModelNameError(cmdName string) error

MissingModelNameError returns an error stating that the model name is missing and provides a better UX experience to the user.

func ModelMachineInfoFromParams Uses

func ModelMachineInfoFromParams(machines []params.ModelMachineInfo) map[string]ModelMachineInfo

ModelMachineInfoFromParams translates []params.ModelMachineInfo to a map of machine ids to ModelMachineInfo.

func ModelSLAFromParams Uses

ParseConstraints parses the given constraints and uses WarnConstraintAliases if any aliases were used.

func PermissionsMessage Uses

func PermissionsMessage(writer io.Writer, command string)

func ProviderConfigSchemaSourceByType Uses

func ProviderConfigSchemaSourceByType(cloudType string) (config.ConfigSchemaSource, error)

ProviderConfigSchemaSourceByType returns a config.ConfigSchemaSource for the environ provider, found for the given cloud type, or an error.

func ReadAuthorizedKeys Uses

func ReadAuthorizedKeys(ctx *cmd.Context, path string) (string, error)

ReadAuthorizedKeys implements the standard juju behaviour for finding authorized_keys. It returns a set of keys in in authorized_keys format (see sshd(8) for a description). If path is non-empty, it names the file to use; otherwise the user's .ssh directory will be searched. Home directory expansion will be performed on the path if it starts with a ~; if the expanded path is relative, it will be interpreted relative to $HOME/.ssh.

The result of utils/ssh.PublicKeyFiles will always be prepended to the result. In practice, this means ReadAuthorizedKeys never returns an error when the call originates in the CLI.

If no SSH keys are found, ReadAuthorizedKeys returns ErrNoAuthorizedKeys.

func RegisterCredentials Uses

func RegisterCredentials(
    ctx *cmd.Context,
    store jujuclient.CredentialStore,
    provider environs.EnvironProvider,
    args modelcmd.RegisterCredentialsParams,

ResolveCloudCredentialTag takes a string which is of either the format "<credential>" or "<user>/<credential>". If the string does not include a user, then the supplied user tag is implied.

func UserFriendlyDuration Uses

func UserFriendlyDuration(when, now time.Time) string

UserFriendlyDuration translates a time in the past into a user friendly string representation relative to the "now" time argument.

func ValidateIaasController Uses

func ValidateIaasController(c modelcmd.CommandBase, cmdName, controllerName string, store jujuclient.ClientStore) error

    c *modelcmd.ModelCommandBase,
    isCAASController bool,
    hostedModelName string,
) (err error)

func (*ConfigFlag) SetAttrsFromReader Uses

func (f *ConfigFlag) SetAttrsFromReader(reader io.Reader) error

SetAttrsFromReader sets the attributes from a slice of bytes. The bytes are expected to be YAML parsable and align to the attrs type of map[string]interface{}. This will over write any attributes that already exist if found in the YAML configuration.

func (*ConfigFlag) SetPreserveStringValue Uses

func (f *ConfigFlag) SetPreserveStringValue(val bool)

SetPreserveStringValue sets whether name values should be converted to a type that is inferred from their string value, by way of YAML unmarshalling,or kept as the original string value. The default behaviour is to apply YAML unmarshalling to the value.
