mergeConfig :: InstanceParams -> InstanceParams -> InstanceParams Source #

Merges two instance configurations into one.

In the case where instance IPs (i.e., map keys) are repeated, the old instance configuration is thrown away by union and replaced by the new configuration. As a result, the old private and secret OS parameters are completely lost.

getOsParams :: String -> String -> JSObject JSValue -> Result (JSObject JSValue) Source #

Extracts the OS parameters (public, private, secret) from a JSON object.

This function checks whether the OS parameters are in fact a JSON object.

getPublicOsParams :: JSObject JSValue -> Result (JSObject JSValue) Source #

getPrivateOsParams :: JSObject JSValue -> Result (JSObject JSValue) Source #

getSecretOsParams :: JSObject JSValue -> Result (JSObject JSValue) Source #

makeInstanceParams :: JSObject JSValue -> JSObject JSValue -> JSObject JSValue -> JSValue Source #

Merges the OS parameters (public, private, secret) in a single data structure containing all parameters and their visibility.

Example:

{ "os-image": ["http://example.com/disk.img", "public"],
  "os-password": ["mypassword", "secret"] }

getOsParamsWithVisibility :: JSValue -> Result JSValue Source #

getInstanceCommunicationIp :: JSObject JSValue -> Result (Maybe String) Source #

Finds the IP address of the instance communication NIC in the instance's NICs. If the corresponding NIC isn't found, Nothing is returned.

getInstanceParams :: JSValue -> Result (String, Maybe InstanceParams) Source #

Extracts the OS parameters from the instance's parameters and returns a data structure containing all the OS parameters and their visibility indexed by the instance's IP address which is used in the instance communication NIC.
