The `queues` commands of Sylphx Events, as the CLI spells them: the same
calls as [the `queues` API page](/docs/api/queues), typed for the
shell. [Install, sign in and the grammar](/docs/cli) are on the CLI index.

## get

Gets a queue.

**`NAME`** — the resource's name; a bare id is enough below the linked
project.

**CLI**

```bash
sylphx events queues get orgs/acme/projects/shop/envs/production/queues/queue
```

`GET https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/queues/queue` · scope `events:read` · effect `read` · [Request, response and examples](/docs/api/queues/get)

## list

Lists queues.

**`PARENT`** — optional: the CLI fills it from the linked project or the
key's scope when it is left out.

**CLI**

```bash
sylphx events queues list orgs/acme/projects/shop/envs/production
```

`GET https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/queues` · scope `events:read` · effect `read` · [Request, response and examples](/docs/api/queues/list)

**Flags**

| Flag | Type | What it does |
| --- | --- | --- |
| `--page-size` | `int` | At most this many; default 50, clamped to 1000. |
| `--page-token` | `string` | `next_page_token` of the previous page. |
| `--filter` | `string` | AIP-160 filter over labels and filterable fields. |
| `--order-by` | `string` | AIP-132 ordering over filterable fields. |

## create

Creates a queue.

**`ID`** — The id segment of the new Resource's name; the server assigns one when omitted.

**CLI**

```bash
sylphx events queues create --parent orgs/acme/projects/shop/envs/production
```

`POST https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/queues` · scope `events:write` · effect `write` · [Request, response and examples](/docs/api/queues/create)

**Flags**

| Flag | Type | What it does |
| --- | --- | --- |
| `--parent` | `string` | The parent to create in; defaults to the linked project or the key's scope. |
| `--meta.labels` | `key=value` | Caller-writable, indexed labels (AIP-122 label rules). Repeat the flag for each value. |
| `--meta.annotations` | `key=value` | Caller-writable, unindexed annotations. Repeat the flag for each value. |
| `--meta.display-name` | `string` | Caller-writable human-readable name. |
| `--spec.visibility-timeout` | `duration` | How long a lease hides a message; default 30s, 1s to 12h. |
| `--spec.max-deliveries` | `int` | Deliveries before a message dead-letters; default 5, 1 to 100. |
| `--spec.dead-letter-queue` | `string` | The dead-letter Queue; unset keeps exhausted messages in this Queue's own dead-letter set. |
| `--spec.retention` | `duration` | How long an unacked message is kept; default 4d, at most 14d. |
| `--dry-run` | `bool` | Validate and print the result without writing (validate_only). |

project.

**CLI**

```bash
sylphx events queues update orgs/acme/projects/shop/envs/production/queues/queue
