pipeline up

Overview

Run your pipeline using docker compose

Aliases: up

Usage:

quix pipeline up [options]

Options:

--directory <directory>: If specified, it will use that directory instead of the current one
-D, --dry-run: Generate 'compose.yaml' without running it
-u, --update: Update 'quix.yaml' with the new local applications and update the variables of the existing deployments
-s, --skip-topics: Skip topics creation, in this case Quix Streams might create the topics automatically
-k, --keep-variables: Keep the locally deleted variables

How It Works

The quix pipeline up command sets up and runs your pipeline using Docker Compose. When executed, it generates the necessary compose.local.yaml file that defines the services in your pipeline. It then builds and starts the Docker containers based on this configuration by running the equivalent of docker compose up --build -d.

If the update option is used, the command updates the quix.yaml file with new local applications and variables of existing deployments. The dry-run option allows you to generate the compose.local.yaml file without starting the containers, providing a preview of the configuration.

Deployments are connected using variables with VariableType of InputTopic and OutputTopic, ensuring seamless data flow between different services.

This process ensures that your pipeline is correctly configured and running with all the necessary services. For more details on the docker compose up command, refer to the official Docker documentation.

Warning

Ensure that Docker is running before executing this command. If Docker is not running, the command will fail. You can verify Docker is running by executing the following command:

docker info

Example usage

Starting the Pipeline with Docker Compose

To start your pipeline, use the following command:

$ quix pipeline up

This command generates the necessary compose.local.yaml file and deployment configurations:

  Generating 'compose.local.yaml'
  Generating deployment demo-data-source
✓ Generated deployment demo-data-source
  Generating deployment event-detection-transformation
✓ Generated deployment event-detection-transformation
✓ Generated 'compose.local.yaml'

Tip

You can also use the --dry-run or -D option to generate the compose.local.yaml file without running it:

$ quix pipeline up --dry-run

When the compose file is generated, it will start the kafka broker first:

Starting the pipeline broker ...

Executing 'docker compose -f compose.local.yaml up --build -d --remove-orphans kafka-broker'

 Container simplebroker-kafka-broker-1  Creating
 Container simplebroker-kafka-broker-1  Created
 Container simplebroker-kafka-broker-1  Starting
 Container simplebroker-kafka-broker-1  Started

Updating the topics

After the broker has started, the topics created automatically with the configuration provided in quix.yaml.

Updating topics ...

✓ Created topic: f1-data
✓ Created topic: hard-braking
✓ No topics to update

✓ Started the pipeline broker

Tip

Use the options --skip-topics or -s if you don't want to skip the topic creation.

Next, it executes docker compose compose.local.yaml up --build -d --remove-orphans to build and run the your application Docker containers:

Executing 'docker compose up --build -d --remove-orphans'

Running the Containers

Once the images are built, Docker Compose will create and start the containers:

Network githubrepo_default  Creating
Network githubrepo_default  Created
Containers  Creating and Starting
Containers  Started

Tip

Using the --update option will perform the same actions as running quix pipeline update before generating the compose.local.yaml file.

Finally you will see your applications running in docker and you will have visual way to manage and view your pipeline topics:

✓ Open http://localhost:8080 to manage your pipeline broker

Generated `compose.local.yaml` File Overview

The compose.local.yaml file configures the services in your pipeline. Here's an overview of what will be generated:

demo-data-source and event-detection-transformation:
- volumes: Mounts a null file to .env, effectively ignoring your local .env folder.
- build: Specifies the context directory and Dockerfile.
- environment: Injects environment variables for Kafka broker addresses and data inputs/outputs. These match the settings in quix.yaml.
```
environment:
  input: f1-data
  output: hard-braking
  Quix__Broker__Address: kafka-broker:9092
```
These environment variables are injected into the container at runtime:
- input: Specifies the input data stream (f1-data).
- output: Specifies the output data stream (hard-braking).
- Quix__Broker__Address: Specifies the address of the Kafka broker (kafka-broker:9092).
kafka-broker and console:
- kafka-broker: Installs and configures a Redpanda Kafka broker for you.
- console: Provides a management interface for interacting with the Kafka broker, including necessary environment configurations.

For more details on the compose.local.yaml file and its configurations, refer to the official Docker Compose documentation.
