| 272 | * target cluster's platform adapter — workload identity and a container |

| 274 | * inline Effect program whose impl returns `{ run }`), `context` (build |
| 275 | * your own Dockerfile), or `image` (a pre-built registry reference). |
| 276 | * `main` and `context` images are built on the deploying machine and |
| 277 | * pushed to the connection's registry (`Kubernetes.LocalCluster` includes |
| 278 | * one; EKS uses ECR; GKE uses Artifact Registry). On `AWS.EKS.Cluster` |
| 279 | * targets, bindings attach IAM policy statements to a generated |
| 280 | * pod-identity role; on `GCP.Container.Cluster` targets, GCP bindings grant |
| 281 | * their IAM roles to the Kubernetes ServiceAccount's Workload Identity |
| 282 | * Federation principal — exactly like `Kubernetes.Deployment`. |
| 283 | * ### Creating a Job |
| 284 | * **Example:** Remote image (external — no Effect runtime in the container) |
| 285 | * ```typescript |
| 286 | * const migrate = yield* Kubernetes.Job("DbMigrate", { |
| 287 | * cluster, |
| 288 | * image: "ghcr.io/acme/migrator:v3", |
| 289 | * backoffLimit: 2, |
| 290 | * }); |
| 291 | * ``` |
| 292 | * |
| 293 | * **Example:** Inline Effect program |
| 294 | * ```typescript |
| 295 | * const cluster = yield* Kubernetes.LocalCluster("Cluster", { |
| 296 | * name: "alchemy", |
| 297 | * }); |
| 298 | * |
| 299 | * const hello = yield* Kubernetes.Job( |
| 300 | * "Hello", |
| 301 | * { cluster, main: import.meta.url, backoffLimit: 2 }, |
| 302 | * Effect.gen(function* () { |
| 303 | * return { |
| 304 | * run: Effect.log("hello from a Job"), |
| 305 | * }; |
| 306 | * }), |
| 307 | * ); |
| 308 | * ``` |
| 309 | * |
| 310 | * **Example:** Inline Effect program with a DynamoDB binding (EKS) |
| 311 | * ```typescript |
| 312 | * const seed = yield* Kubernetes.Job( |
| 313 | * "SeedData", |
| 314 | * { cluster, main: import.meta.url }, |
| 315 | * Effect.gen(function* () { |
| 316 | * const putItem = yield* AWS.DynamoDB.PutItem(table); |
| 317 | * return { |
| 318 | * run: Effect.gen(function* () { |
| 319 | * yield* putItem({ Item: { id: { S: "seed" } } }); |
| 320 | * }), |
| 321 | * }; |
| 322 | * }).pipe(Effect.provide(AWS.DynamoDB.PutItemHttp)), |
| 323 | * ); |
| 324 | * ``` |
| 325 | * |
| 326 | * **Example:** Tagged Effect program |
| 327 | * ```typescript |
| 328 | * export class Backfill extends Kubernetes.Job<Backfill, { |
| 329 | * progress: () => Effect.Effect<number>; |
| 330 | * }>()("Backfill") {} |
| 331 | * |
| 332 | * export default Backfill.make( |
| 333 | * { cluster, main: import.meta.url, backoffLimit: 1 }, |
| 334 | * Effect.gen(function* () { |
| 335 | * return { |
| 336 | * run: Effect.gen(function* () { }), |
| 337 | * progress: () => Effect.succeed(0), |
| 338 | * }; |
| 339 | * }), |
| 340 | * ); |
| 341 | * ``` |
| 342 | * |
| 343 | * ### Bundling & Tree-shaking |
| 344 | * `main` is bundled with rolldown at deploy time. Unused code is |
| 345 | * tree-shaken. `effect`, alchemy, and `@distilled.cloud` are marked |
| 346 | * pure so unused parts prune more aggressively. Your app is not |
| 347 | * marked pure. |
| 348 | * |
| 349 | * **Example:** Mark additional packages as pure |
| 350 | * Only list packages with no top-level side effects. |
| 351 | * ```typescript |
| 352 | * { |
| 353 | * main: import.meta.url, |
| 354 | * build: { |
| 355 | * pure: { packages: ["my-lib", "@my-scope/*"] }, |
| 356 | * }, |
| 357 | * } |
| 358 | * ``` |
| 359 | * |
| 360 | * **Example:** Turn it off |
| 361 | * ```typescript |
| 362 | * { |
| 363 | * main: import.meta.url, |
| 364 | * build: { pure: false }, |
| 365 | * } |
| 366 | * ``` |
| 367 | * |
| 368 | * ### Scheduling |
| 369 | * **Example:** Nightly CronJob |
| 370 | * ```typescript |
| 371 | * const nightly = yield* Kubernetes.Job("NightlyBackfill", { |
| 372 | * cluster, |
| 373 | * main: import.meta.url, |
| 374 | * schedule: "0 3 * * *", |
| 375 | * }); |
| 376 | * ``` |

| 379 | * @product Workloads |
