Oskar Otwinowski b98cceb8fb docs: task version skew protection, --external-id, and the atomic deployments deprecation (#4742)
New deployment/version-skew-protection page: the skew problem, the
--external-id primitive and its reuse behaviour, runtime discovery (call
option, configure(), TRIGGER_EXTERNAL_DEPLOYMENT_ID, and the gated
platform/CI/generic commit-SHA variables with the build-time caveat),
the
manual any-platform recipe, waiting/expiry semantics, precedence, and
automatic skew protection on Vercel. Deprecation callouts on the atomic
deployments page and the Vercel integration page; --external-id/--force
added to the CLI deploy reference; redirect from
deployment/vercel-skew-protection so existing webapp links resolve
(TRI-13002).

Run the command like this:
<CodeGroup>
```bash npm
npx trigger.dev@latest deploy
```
```bash pnpm
pnpm dlx trigger.dev@latest deploy
```
```bash yarn
yarn dlx trigger.dev@latest deploy
```
</CodeGroup>
<Warning>
This will fail in CI if any version mismatches are detected. Ensure everything runs locally first
using the [dev](/cli-dev-commands) command and don't bypass the version checks!
</Warning>
It performs a few steps to deploy:
1. Optionally updates packages when running locally.
2. Compiles and bundles the code.
3. Deploys the code to the Trigger.dev instance.
4. Registers the tasks as a new version in the environment (prod by default).
## Deploying from CI
When deploying from CI/CD environments such as GitHub Actions, GitLab CI, or Jenkins, you need to authenticate non-interactively by setting the `TRIGGER_ACCESS_TOKEN` environment variable. Please see the [CI / GitHub Actions guide](/github-actions) for more information.
## Arguments
```
npx trigger.dev@latest deploy [path]
```
<ProjectPathArg />
## Options
<ConfigFileOption />
<ProjectRefOption />
<EnvFileOption />
<SkipUpdateCheckOption />
<ParamField body="Environment" type="--env | -e">
Defaults to `prod` but you can specify `staging` or `preview`. If you specify `preview` we will
try and automatically detect the branch name from git.
</ParamField>
<BranchOption />
<ParamField body="Dry run" type="--dry-run">
Create a deployable build but don't deploy it. Prints out the build path so you can inspect it.
</ParamField>
<ParamField body="Skip promotion" type="--skip-promotion">
Skips automatically promoting the newly deployed version to the "current" deploy.
</ParamField>
<ParamField body="Skip syncing env vars" type="--skip-sync-env-vars">
Turn off syncing environment variables with the Trigger.dev instance.
</ParamField>
<ParamField body="External id" type="--external-id">
Attach your own identifier to this deployment — a commit SHA, release tag or CI run id, up to 128
characters. Your app can then send the same id when triggering, and runs are pinned to this
deployment. See [version skew protection](/deployment/version-skew-protection).
Repeating an id that is already deployed doesn't build again: the CLI reports the existing version,
sets the same outputs, and exits successfully. Repeating an id that has a build in flight is an
error. An id whose build failed rebuilds normally.
The short-circuit is keyed on the id, not on the build inputs — so redeploying the same id after
changing a synced environment variable produces no new build.
</ParamField>
<ParamField body="Force" type="--force">
Start a new build for an `--external-id` that already has one. Non-destructive with respect to
deployments that already succeeded — both remain and the newer version wins. If a build for that
id is still in flight, `--force` **cancels** it first, so one id never has two live builds. A
cancelled build usually stops within seconds, but one running on another machine can keep going
briefly before it notices. Requires `--external-id`.
</ParamField>
<ParamField body="Local build" type="--local-build">
Force building the deployment image locally using your local Docker. This is automatic when self-hosting.
</ParamField>
### Common options
These options are available on most commands.
<CommonOptions />
### Self-hosting
When [self-hosting](/self-hosting/overview), builds are performed locally by default. Once you've logged in to your self-hosted instance using the CLI, you can deploy with:
```bash
npx trigger.dev@latest deploy
```
For CI/CD environments, set `TRIGGER_ACCESS_TOKEN` and `TRIGGER_API_URL` environment variables. See the [GitHub Actions guide](/github-actions#self-hosting) for more details.
