# Serverless Boilerplate - OpenWhisk - Python Make sure `serverless` is installed. [See installation guide](https://serverless.com/framework/docs/providers/openwhisk/guide/installation/). You will also need to set up your OpenWhisk account credentials using environment variables or a configuration file. Please see the [this guide for more information](https://serverless.com/framework/docs/providers/openwhisk/guide/credentials/). ## 1. Install Provider Plugin `npm install -g serverless-openwhisk` ## 2. Install Service Dependencies `npm install` in this directory to download the modules from `package.json`. ## 3. Deploy `serverless deploy` or `sls deploy`. `sls` is shorthand for the Serverless CLI command Make a note of the API endpoint that is logged to the console during deployment. ``` endpoints: GET https://xxx.api-gw.mybluemix.net/python-service/ping --> python-service-dev-currentTime ``` ## 4. Invoke deployed function `serverless invoke --function currentTime` or `serverless invoke -f currentTime` `-f` is shorthand for `--function` In your terminal window you should see the response from Apache OpenWhisk ```bash { "message": "Hello stranger, the current time is 15:59:30.983379" } ``` ## 5. Test HTTP endpoint Use a HTTP client to access the endpoint for your function. The endpoint will be the API gateway root path, logged during deployment, and your configured function path. ``` $ http get https://xxx.api-gw.mybluemix.net/python-service/ping HTTP/1.1 200 OK ... { "message": "Hello stranger, the current time is 16:00:11.837331" } $ http get https://xxx.api-gw.mybluemix.net/python-service/ping?name=James HTTP/1.1 200 OK ... { "message": "Hello James, the current time is 16:00:15.749699" } ``` **For more information on the Serverless OpenWhisk plugin, please see the project repository: [https://serverless.com/framework/docs/providers/aws/guide/credentials/](https://serverless.com/framework/docs/providers/aws/guide/credentials/).**
