# Deploying Agents

> How deploys resolve to environments, branches, and versions

## The Core Command

```bash theme={"dark"}
tu deploy
```

The CLI reads `config.yaml`, resolves the effective branch, builds an image, and creates a new version for the matching environment.

## The Deployment Model

| Resource      | Meaning                                          |
| ------------- | ------------------------------------------------ |
| `Environment` | A named policy such as `production` or `preview` |
| `Branch`      | A branch-specific deployment slot                |
| `Version`     | One deployed build of your agent                 |

Every deploy creates a new version. A branch points at the current active version.

## Branch Resolution

For `tu deploy`, the branch comes from:

1. `--branch`, if provided
2. the current git branch
3. fallback logic when git context is unavailable

The platform then resolves that branch to an environment using branch rules.

In a default setup:

| Branch         | Environment  | Config section          |
| -------------- | ------------ | ----------------------- |
| `main`         | `production` | `deployment.production` |
| other branches | `preview`    | `deployment.preview`    |

## config.yaml

```yaml theme={"dark"}
agent:
  name: my-namespace/my-agent
  description: Example agent
  sdk_type: claude_agent_sdk

deployment:
  production:
    replicaCount: 1
    areTasksSticky: true
  preview:
    replicaCount: 1
    areTasksSticky: false
```

## Task Stickiness

`areTasksSticky` controls what happens to running tasks during a rollout.

| Setting | Behavior                                          |
| ------- | ------------------------------------------------- |
| `true`  | Running tasks stay on the version they started on |
| `false` | Running tasks can migrate during rollout          |

If you need to move running tasks later, use `tu tasks migrate`.

## Environment Secrets

Runtime secrets are environment-scoped.

Use `tu env add` to set them and `tu env ls`, `tu env get`, `tu env rm`, `tu env pull`, and `tu env import` to manage them.

Your code reads them through normal environment variables:

```python theme={"dark"}
import os

api_key = os.environ["API_KEY"]
```

## Rollback

Use `tu rollback` to move a branch back to an earlier version.

```bash theme={"dark"}
tu rollback
```

Rollback uses the target version's secret snapshot. Pending environment-secret changes are not rewritten by the rollback.

## Deployment History

Use `tu ls` to inspect version history and branch events:

```bash theme={"dark"}
tu ls
tu ls <branch>
```

Use `tu logs` to inspect runtime behavior:

```bash theme={"dark"}
tu logs
tu logs <namespace/agent> --since 1h --level WARNING
```

## Useful Flags

| Command       | Common flags                                                                              |
| ------------- | ----------------------------------------------------------------------------------------- |
| `tu deploy`   | `--config`, `--branch`, `--skip-build`, `--no-cache`, `--yes`, `--verbose`, `--detach`    |
| `tu rollback` | `--branch`, `--version`, `--agent`, `--config`, `--yes`, `--json`                         |
| `tu logs`     | `--task`, `--level`, `--source`, `--since`, `--until`, `--version`, `--limit`, `--follow` |

## Remote Builds

Remote build mode is controlled by the CLI runtime, and when enabled it builds remotely instead of locally.

One important constraint: remote builds are `linux/amd64` only.

See [CLI Reference](/api-reference/cli) for command details.
