UCAM PURE STORAGEModule DocumentConfluence DocumentIntroductionThe CLI developed in this project allows the user to interact with PureStorage using REST API.With this CLI, you can list the existing volumes, servers, etc, on the Pure Storage, clone volumes, create snapshots, replace existing volumes with a golden image, etc. It is also able to configure system /etc/fstab and multipath when needed in some operations like volume mapping and mounting.Running the ApplicationPrerequisitesrequests 2.30.0pyjwt[crypto]paramiko 3.1.0distro 1.8.0Download the private key from the 1PASSWORD utilized to create the API account on the purestorage and fetch the credentials required.Pure Storage Arrays [user and passowrd]PureAPI information [client_id, key_id, client_name, storage, keyfile]InstallationTo install the ucampurestorage pip packageRHEL 7scl enable rh-python38 bash

    Manage Pure Storage Manager objects via REST API.

    positional arguments:
    {tokengen,list,volume,host,snapshot}
        tokengen            Generate Pure Storage API token to access objects. Example: ucampurestorage tokengen --keyfile "./key.pem"
        list                List Pure objects.
        volume              Operations with respect to volumes in the Pure objects.
        host                Operations with respect to hosts in the Pure objects.
        snapshot            Operations with respect to snapshots in the Pure objects.
