After the migration is complete, **all charts will be removed from ChartMuseum**, and **old HTTP(S)-based chart repositories will no longer work in Rancher**. 372 - 373 -To ensure a smooth transition, each project should **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase. 374 - 375 -We will make your charts available in the corresponding new `<pkey>-helm` OCI projects. 376 - 377 ---- 378 - 379 -## Terminology 380 -| Term | Meaning | 381 -|------|---------| 382 -| **Old Repository** | The existing HTTP/HTTPS ChartMuseum repository. | 383 -| **New Repository** | The new OCI-based Helm chart repository created for your project (e.g. `<chart-repo-name>` in `<pkey>-helm`). | 384 - 385 ---- 386 - 387 -## Why This Migration Is Required 388 -- ChartMuseum is deprecated and will be removed. 389 -- Applications deployed from old repos keep a reference to that repo inside their labels. 390 -- Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions**. 391 - 392 ---- 393 - 394 -## Migration Steps 395 - 396 -### 1. Create the New OCI Repository in Rancher 397 -1. Go to **Apps → Repositories**. 398 -2. Add a new repository of type **OCI**. 399 -3. Name it exactly like your old repo name (e.g. `<chart-repo-name>`). 400 -4. Point it to the new OCI endpoint. 401 - 402 ---- 403 - 404 -### 2. Disable the Old ChartMuseum Repository Temporarily 405 -This step ensures that Rancher resolves charts from the new OCI repo. 406 - 407 -1. Go to **Apps → Repositories**. 408 -2. Disable the old HTTP(S)-based repository. 409 -3. Keep it disabled until the migration is done. 410 - 411 ---- 412 - 413 -### 3. Update Existing Applications to Use the New OCI Repo 414 -Applications deployed with the old repository still contain the old repo name in their metadata. 415 -You must upgrade them once to transition. 416 - 417 -1. Go to **Apps → Installed Apps**. 418 -2. Open the application that was deployed using the old repo. 419 -3. Click **Upgrade**. 420 -4. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**. 421 -5. Choose the chart version you want to deploy (same or newer). 422 -6. Click **Upgrade**. 423 - 424 -After this upgrade: 425 -- Your application is now linked to the **new OCI repository**. 426 -- Rancher will show upgrade notifications only for versions available in the new repo. 427 - 428 ---- 429 - 430 -### 4. Re-enable the Old Repository (Optional) 431 -If you still need the old repo for other apps, re-enable it after the migration steps above. 432 - 433 -> Note: Even if a newer chart version exists in the old repository, your migrated app **will not see it**, because it is no longer connected to that repo. 434 - 435 ---- 436 - 437 -## Reverting the Migration (If Needed) 438 -If you want to move an app back to the old repository: 439 -1. Temporarily disable the new OCI repo. 440 -2. Enable the old ChartMuseum repo. 441 -3. Open the application → **Upgrade**. 442 -4. Select the chart from the old repo. 443 -5. Save. 444 - 445 -This will reconnect the app to the old repository. 446 - 447 ---- 448 - 449 -## Summary 450 -- Add new OCI repo → disable old repo → upgrade apps → reconnect to OCI repo. 451 -- After upgrade, apps no longer track versions from the old repository. 452 -- Old repository will stop functioning after ChartMuseum shutdown, so migration is required. 453 - 454 ---- 455 - 456 -If you want, I can also generate: 457 -- a shorter version (1-pager), 458 -- a diagram, 459 -- a Rancher UI screenshot guide, 460 -- or a version tailored for your team’s internal wiki. 461 - 462 - 463 463 = Automated deployments with Jenkins = 464 464 465 465 In this section, we describe(% style="color:#172b4d" %) how to set-up **automated builds, tests and deployments** for Jenkins.
