# Basic Task

> A simple task that runs steps in order

This example demonstrates the most basic Tekton Task structure, showing how steps are executed sequentially.

## Example

This TaskRun executes two steps in order. The first step creates a file, and the second step verifies its existence:

```yaml theme={null}
apiVersion: tekton.dev/v1
kind: TaskRun
metadata:
  generateName: steps-run-in-order-
spec:
  taskSpec:
    steps:
    - image: mirror.gcr.io/busybox
      # NB: command is not set, so it must be looked up from the registry.
      args: ['-c', 'sleep 3 && touch foo']
    - image: mirror.gcr.io/busybox
      args: ['-c', 'ls', 'foo']
```

## How It Works

<Steps>
  <Step title="First Step Runs">
    The first step sleeps for 3 seconds, then creates a file named `foo`. The command is automatically looked up from the container image registry since no explicit `command` is specified.
  </Step>

  <Step title="Second Step Executes">
    After the first step completes successfully, the second step runs and lists the `foo` file to verify it was created.
  </Step>

  <Step title="Sequential Execution">
    Tekton guarantees that steps run in the order they're defined. The second step will not start until the first step completes.
  </Step>
</Steps>

## Key Concepts

* **Steps**: Individual units of execution within a Task
* **Sequential Execution**: Steps run in order, one after another
* **Shared Workspace**: Steps share the same filesystem, allowing them to pass data through files
* **generateName**: Creates a unique name for each TaskRun instance

## Expected Output

When this TaskRun executes successfully:

1. The first step completes after 3 seconds
2. The second step finds the `foo` file
3. The TaskRun status shows as "Succeeded"
