| input/output data for a function, create and invoke a task and get execution |
| results with the Teclave's client SDK in both single and multi-party setups.</p> <p>Before trying these examples, please make sure all services in the Teaclave |
| platform has been properly launched. Also, for examples implemented in Python, |
| don't forget to generate protocol stub files and set the <code>PYTHONPATH</code> to the |
| <code>sdk</code> path so that the scripts can successfully import the <code>teaclave</code> module.</p> <p>Generate stub files by grpcio-tools and grpclib.</p> <div class="language- extra-class"><pre class="language-text"><code>python3 -m grpc_tools.protoc --proto_path=../../services/proto/src/proto --python_out=. --grpclib_python_out=. ../../services/proto/src/proto/{teaclave_authentication_service.proto,teaclave_frontend_service.proto,teaclave_common.proto} |
| </code></pre></div><p>For instance, use the following command to invoke an echo function in Teaclave:</p> <div class="language- extra-class"><pre class="language-text"><code>$ PYTHONPATH=../../sdk/python python3 builtin_echo.py 'Hello, Teaclave!' |
| </code></pre></div><p>Please checkout the sources of these examples to learn more about the process of |
| invoking a function in Teaclave.</p> <h2 id="configuring-urls-of-input-output-files"><a href="#configuring-urls-of-input-output-files" class="header-anchor">#</a> Configuring URLs of Input/Output Files</h2> <p>In some of the examples, you will see URLs of input and output files pointing to |
| the <code>localhost</code> addresses. In real world, these URLs are addresses from file |
| system service providers (i.e., AWS S3). If you are using the Docker compose |
| file to start Teaclave services, a simple file system service are also included. |
| To use it, just change the URLs in the examples to |
| <code>http://teaclave-file-service:6789/path/to/the/file</code>.</p> <p>Normally, the domain name is <code>teaclave-file-service</code>, and it can be found via |
| the <code>docker ps</code> command under the "NAMES" column:</p> <div class="language- extra-class"><pre class="language-text"><code>CONTAINER ID || IMAGE || COMMAND || CREATED || STATUS || NAMES |
| XXXXXXXX || python:3 || "./scripts/simple_ht…" || 1 days ago || Up 1 days || teaclave-file-service |
| </code></pre></div><p>Note that in a real-world case, URLs of input and output files should be |
| provided by the end-user. In the examples, we just embed these files for |
| demonstration and testing.</p></div> <footer class="page-edit"><!----> <div class="last-updated"><span class="prefix">Last Updated:</span> <span class="time">5/10/2023, 6:15:57 AM</span></div></footer> <div class="page-nav"><p class="inner"><span class="prev"> |

| Apache Teaclave (incubating) is an effort undergoing incubation at The Apache |
| Software Foundation (ASF), sponsored by the Apache Incubator. |
| Incubation is required of all newly accepted projects until a further review |
| indicates that the infrastructure, communications, and decision making process |
| have stabilized in a manner consistent with other successful ASF projects. While |
| incubation status is not necessarily a reflection of the completeness or |
| stability of the code, it does indicate that the project has yet to be fully |
| endorsed by the ASF. |
