# tapipy - Tapis V3 Python SDK Python library for interacting with an instance of the Tapis API Framework. The library is automatically generated by referencing the OpenAPI spec files which a `Tapis` object built from the OpenAPI spec files from TACC's Tapis services. With this functionality a user is able to authorize itself with the `Tapis` object and have a 'live' library in order to interact with Tapis services. ## Development This project is under active development, exploring different approaches to SDK generation. ## Installation Tapipy is packaged on [pypi](https://pypi.org/project/tapipy/) and can be installed with pip. ``` pip install tapipy ``` ## Usage Tapipy's Tapis object first must be initialized in order to be used. A basic example of logging in with a user account is below. ``` # Import the Tapis object from tapipy.tapis import Tapis # Log into you the Tapis service by providing user/pass and the base url of your tenant. For example, to interact with the tacc tenant -- t = Tapis(base_url='https://tacc.tapis.io', username='myuser', password='mypass') # Get tokens that will be used for authentication function calls t.get_tokens() ``` Now you have a Tapis object that is authenticated and able to call Tapis service endpoints. It's useful to know that the Tapis object will automatically refresh it's token if it is deemed appropriate, so the object should stay in the good graces of Tapis indefinitely. Now in order to use the Tapis object you can reference the [Tapis Framework](https://tapis-project.github.io/live-docs/) to browse all functions. For example, if I wanted to use the SK service in order to check if a user has a specific role I would find the function on the site (which is just a better way to look at the json specs). With the site I can see that I need to use my Tapis object, initialized as `t`, access `sk`, and then use the `hasRole` function with the required inputs as follows. ``` t.sk.hasRole(tenant='dev', user='_testuser', roleName='Do you have this role?') ``` # Development Docs ## Running the tests Tests resources are contained within the `test` directory. `Dockerfile-tests` is at root. 1. Build the test docker image: `docker build -t tapis/tapipy-tests -f Dockerfile-tests .` 2. Run these tests using the built docker image: `docker run -it --rm tapis/tapipy-tests` ## Important Parameters to Know The Tapipy package allows for spec file customization in Tapis object initialization: * resource_set: str * Determines which set of resource to use, master or dev, defaults to master. * Important to note that if a custom_spec_dictionary is used, it is appended to this resource_set. * For example, you would set master and then specify a custom specs that will be added on. * custom_spec_dict: {resource_name: str, resource_url: str} * Allows users to modify the base resource set urls. * e.g. I can specify actor as a resource name and change the url. * Also allows users to add new resources to the set. * e.g. I can add a new resource named "test" with a custom url. * Important that know that any new specs will be downloaded and added to the cache * No need to specify download_latest_specs or update spec files. * ALLOWS LOCAL RESOURCES! * Specify an absolute path in the dict with `local:` prefixing it and tapipy will load in a local OpenAPI v3 yml spec file. * `custom_spec_dict={'cactus': 'local: /home/tapis/myfolder/cactusSpec.yml'}` * download_latest_specs: bool * Allows users to re-download all specs regardless on if they already exist in the cache. Defaulted to False * This will happen every time the Tapis object is initialized, it's a tad slower, and can cause live updates to specs. * As such, be warned. There are functions to update spec files below. * spec_dir: str * Allows users to specify folder to save specs to. Defaults to none which uses Tapipy's package folder. * If you are updating specs it's wise to use a different folder in order to not modify the base specs. The following is an example of some custom parameter setting. As you can see, the abaco resource will now use the spec at `URL#1`, overwriting the resource definition in the master resource set, it'll download it if it doesn't exist. The same for the longhorn resource. This means that the Tapis object will now have access to all specs in master like normal, but with a modified abaco and with a new longhorn resource. All of these are stored at the new spec_dir because I don't want to accidentally overwrite any base specs if I call `update_spec_cache()` later (talked about in the next section). ``` from tapipy.tapis import Tapis t = Tapis(base_url='https://admin.develop.tapis.io', tenant_id='admin', username='username', account_type='user', password='password', resource_set='admin', custom_spec_dict={'abaco': 'URL#1', 'longhorn': 'URL#2'}, 'cactus': 'local: /home/tapis/myfolder/cactusSpec.yml'}, spec_dir='/home/username/tapipy_specs') t.get_tokens() ``` ## Update Specs Files The Tapipy package now uses a cache to organize spec dictionaries as pickled files and has the ability to accept custom spec files. By default Tapipy keeps a set of base spec files in the `%tapipy%/specs` folder. These specs are pre-pickled at package creation time. In order to update all default spec files a user can use the `update_spec_cache()` function. Said function's definition is below. If no resources are provided the function will download all default spec urls in the RESOURCES object in `%tapipy%/tapipy/tapis.py` file. ``` Resources = Dict[ResourceName, ResourceUrl] update_spec_cache(resources: Resources = None, spec_dir: str = None) ``` Users are able to specify custom resources to download by providing their own resource dictionary. For example, providing `{'actors': 'URLToMyActorDictionary'}` would update that spec. Users can also specify here where to update the spec with the `spec_dir` variable. The Tapis object itself also has a `update_spec_cache()` function that takes the Tapis parameters given at startup and updates the spec cache. Meaning that if the Tapis object was given a custom dictionary, the `update_spec_cache()` function would update it without the need for setting parameters. ``` t.update_spec_cache() ``` ## Build instructions Building is done with poetry as follows: ``` pip install poetry poetry install ``` This installs `tapipy` to a virtual environment. Run a shell in this environment with: ``` poetry shell ``` To install locally (not in a virtual environment): ``` pip install poetry poetry build cd dists pip install *.whl ``` ## PyPi Push Instructions ``` poetry build poetry publish ``` ## Archive Usage TODO - provide working examples, e.g., ``` import tapipy t = tapipy.Tapis(base_url='http://localhost:5001') req = t.tokens.NewTokenRequest(token_type='service', token_tenant_id='dev', token_username='admin') t.tokens.create_token(req) import openapi_client configuration = openapi_client.Configuration() configuration.host = 'http://localhost:5001' api_instance = openapi_client.TokensApi(openapi_client.ApiClient(configuration)) new_token = openapi_client.NewTokenRequest(token_type='service', token_tenant_id='dev', token_username='admin') resp = api_instance.create_token(new_token) jwt = resp.get('result').get('access_token').get('access_token') ```
