Temporal: Bulletproof Workflows

Step 1/4: Installation

Install Temporal CLI

To install the Temporal CLI, download the version for your architecture:

• Download Temporal CLI for Linux amd64
• Download Temporal CLI for Linux arm64

For example: temporal_cli_1.1.2_linux_amd64.tar.gz file.

Extract the downloaded archive. Example:

$ tar xzf temporal_cli_1.1.2_linux_amd64.tar.gz

Add the temporal binary to your PATH by copying it to a directory like /usr/local/bin/. Example:

$ mv temporal /usr/local/bin/

Install Temporal SDK

Install the Temporal Python SDK:

$ pip install temporalio

Step 2/4: Start Temporal Server

Open a new terminal window and run the following command:

$ temporal server start-dev

This command starts a local Temporal Server. It starts the Web UI, creates the default Namespace, and uses an in-memory database.

The Temporal Service will be available on localhost:7233. The Temporal Web UI will be available at http://localhost:8233.

Leave the local Temporal Server running. You can stop the Temporal Service at any time by pressing Ctrl+C.

Step 3/4: Start Temporal Worker

Open a new terminal window and run the following command:

$ python3 worker.py

Leave the Temporal Worker running.

Step 4/4: Execute Temporal Workflow

Open a new terminal window and run the following command:

$ python3 app.py

Example output:

Result: Hello World!
