# Manual deployment

You can deploy your data projects to Tinybird Cloud directly from the command line using the [Tinybird CLI](/forward/dev-reference/commands).

{% callout type="info" %}
If your project was initialized with `tb init --dev-mode local` or `tb init --dev-mode branch`, running `tb deploy` without explicit environment flags targets your cloud main workspace automatically.
{% /callout %}

## What is a deployment?

Deployments are versions of your project resources and data running on local or cloud infrastructure.

There are two types of deployments:

- **Staging deployments**: Deployments you can use to validate your changes. You access them using the `--staging` flag.
- **Live deployments**: Deployments that make your changes available to your users.

Each type can be deployed to Tinybird Local (`--local`) or Tinybird Cloud (`--cloud`).

### Deployment status

Deployments have the following statuses:

- `In progress`: The deployment is in progress. Use `--wait` to wait for it to finish.
- `Live`: The deployment is active and has been promoted from staging.
- `Staging`: The deployment is active in staging. Use `--staging` to access it.
- `Failed`: The deployment failed. Try `tb deploy --check` to debug the issue.
- `Deleted`: The deployment was deleted as a result of creating new deployments.

## Deploy from the CLI

{% steps %}

### Check the deployment

Before creating the deployment, you can check the deployment with the `--check` flag. This runs a series of checks to ensure the deployment is ready. This is similar to a dry run.

```shell
tb --cloud deployment create --check
```

{% callout type="info" %}
The `--check` flag validates external connections to S3, Kafka, GCS, and databases referenced via table functions. For local success, set connection secrets with `tb secret set` and use `tb local start --use-aws-creds` for S3 connections.
{% /callout %}

### Create a staging deployment

Create a new staging deployment in Tinybird Cloud. Pass the `--wait` flag to wait for the deployment to finish:

```shell
tb --cloud deployment create --wait
```

To run commands against the staging deployment, use the `--staging` flag. For example:

```shell
tb --staging --cloud endpoint ls
```

### Promote to live

When the staging deployment is ready, promote it to a live deployment in Tinybird Cloud:

```shell
tb --cloud deployment promote
```

{% /steps %}

{% callout type="tip" %}
To deploy and promote in one step, use `tb deploy`. If you prefer explicit flags, run `tb --cloud deploy`.
{% /callout %}

## Staging deployments

You can write data to, and read data from, a staging deployment before promoting it to live. This is useful when you've made schema changes that might be incompatible with the current live deployment, like adding new columns.

{% callout type="info" %}
Automatic data source changes that Tinybird applies with `ALTER`, such as adding a column or changing a data source TTL, are applied only when the deployment is promoted to live. Those changes aren't available in staging deployments.
{% /callout %}

### Writing to staging deployments

You can use the [Events API](/forward/ingest-data/events-api) to write directly to staging deployments through the `__tb__min_deployment` parameter, which indicates the target deployment ID. For example:

```shell
curl \
    -H "Authorization: Bearer <import_token>" \
    -d '{"date": "2020-04-05 00:05:38", "city": "Chicago", "new_column": "value"}' \
    '{% user("apiHost") %}/v0/events?name=events_test&__tb__min_deployment=5'
```

In the example, if the ID of your current live deployment is 4 and you're creating deployment with an ID of 5, the data will be ingested into the staging deployment 5 only.
This allows you to:

1. Make schema changes in a staging deployment.
2. Ingest data compatible with the new schema.
3. Validate the changes work as expected.
4. Promote the deployment to live when ready.

Without the parameter, data would be rejected if it doesn't match the schema of the current live deployment.

{% callout type="tip" %}
To get the deployment ID, run `tb deployment ls`.
{% /callout %}

### Reading from staging deployments

You can query data from a staging deployment using [pipe endpoints](/forward/core-concepts/api-endpoints). To access a staging endpoint, add the `__tb__deployment` parameter to your API request:

```shell
curl \
    -H "Authorization: Bearer <query_token>" \
    '{% user("apiHost") %}/v0/pipes/my_endpoint?__tb__deployment=5'
```

This allows you to:

1. Test your endpoints with the new schema changes.
2. Validate query results before promoting to live.
3. Ensure your application works correctly with the updated data structure.

{% callout type="tip" %}
To get the deployment ID, run `tb deployment ls`.
{% /callout %}

### Continuous operation

Once the deployment is promoted to live, you can continue using the same API calls. The `__tb__min_deployment` or `__tb__deployment` parameters ensure compatibility both before and after promotion.

For more details on the Events API parameters, see the [Events API Reference](/api-reference/events-api).

## On-demand compute for deployment populates

When a deployment needs to populate Data Sources, such as when creating Materialized Views or evolving schemas, Tinybird can run the populate on dedicated on-demand compute instead of your main workspace infrastructure. This keeps the populate isolated from production query and ingestion workloads.

Tinybird automatically uses on-demand compute for large deployment populates. For pricing, regional rates, and example calculations, see [On-demand CPUs](/forward/pricing#on-demand-cpus).
