type VirtualPathParams 

type VirtualPathParams []string

VirtualPathParams are an ordered list of additional optional parameters for a virtual path. They can be used to specify a more exact resource name if multiple might be available. Simpler integrations can instead only specify the kind and it will apply wherever a more specific env var isn't found.

func VirtualPathAppParams 

func VirtualPathAppParams(appName string) VirtualPathParams

VirtualPathAppParams returns parameters for selecting specific apps by name.

func VirtualPathCAParams 

func VirtualPathCAParams(caType types.CertAuthType) VirtualPathParams

VirtualPathCAParams returns parameters for selecting CA certificates.

func VirtualPathDatabaseParams 

func VirtualPathDatabaseParams(databaseName string) VirtualPathParams

VirtualPathDatabaseParams returns parameters for selecting specific database certificates.

func VirtualPathKubernetesParams 

func VirtualPathKubernetesParams(k8sCluster string) VirtualPathParams

VirtualPathKubernetesParams returns parameters for selecting k8s clusters by name.

type WebClient 

type WebClient struct {
	*roundtrip.Client
}

WebClient is a package local lightweight client used in tests and some functions to handle errors properly

func NewWebClient 

func NewWebClient(url string, opts ...roundtrip.ClientParam) (*WebClient, error)

func (*WebClient) Delete 

func (w *WebClient) Delete(ctx context.Context, endpoint string) (*roundtrip.Response, error)

func (*WebClient) DeleteWithParams 

func (w *WebClient) DeleteWithParams(ctx context.Context, endpoint string, val url.Values) (*roundtrip.Response, error)

func (*WebClient) Get 

func (w *WebClient) Get(ctx context.Context, endpoint string, val url.Values) (*roundtrip.Response, error)

func (*WebClient) PostJSON 

func (w *WebClient) PostJSON(ctx context.Context, endpoint string, val interface{}) (*roundtrip.Response, error)

func (*WebClient) PostJSONWithFallback 

func (w *WebClient) PostJSONWithFallback(ctx context.Context, endpoint string, val interface{}, allowHTTPFallback bool) (*roundtrip.Response, error)

PostJSONWithFallback serializes an object to JSON and attempts to execute a POST using HTTPS, and then fall back to plain HTTP under certain, very specific circumstances.

  • The caller must specifically allow it via the allowHTTPFallback parameter, and
  • The target host must resolve to the loopback address.

If these conditions are not met, then the plain-HTTP fallback is not allowed, and a the HTTPS failure will be considered final.

func (*WebClient) PutJSON 

func (w *WebClient) PutJSON(ctx context.Context, endpoint string, val interface{}) (*roundtrip.Response, error)
