What its author says it does
Copied from the file, not written here
Operate FrontendExtension (FE) resources in frontend-forge: create, update, rebuild, inspect package artifacts, download packages, publish, unpublish, delete, and debug package/publish controller behavior. Use this skill whenever the user mentions FE operations, FrontendExtension lifecycle, extension package/download/publish/unpublish, artifact ConfigMaps, package Jobs, publisher Jobs, publish target ConfigMaps or Secrets, rebuild-token, package-state/publish-state labels, or troubleshooting FE status in a Kubernetes cluster.

Frontend Forge FE Operations
When to use
Use this skill for operational work around FrontendExtension resources:
- Create or update an FE manifest
- Trigger or inspect package generation
- Force a rebuild with the rebuild-token annotation
- Download the generated package artifact
- Publish, unpublish, or delete an extension
- Inspect FE status, conditions, labels, Jobs, artifact ConfigMaps, and publish targets
- Debug FE package phases such as
Packaging,Ready, andFailed, plus publish/unpublish phases such asPending,Running,Succeeded, andFailed
If the task is about FrontendIntegration runtime JSBundle creation, use the FI operations skill instead. FE package/publish does not create a runtime JSBundle in the current cluster.
Quick Entry
- Create or update FE -> read
references/lifecycle.md - Rebuild package -> read
references/lifecycle.md - Publish, unpublish, delete-with-unpublish, list through API, or download -> read
references/api.md - Inspect package Job, artifact ConfigMap, publish Job, labels, or conditions -> read
references/inspection.md - Debug stuck or failed state -> read
references/inspection.md, then check controller logs
Preconditions
- The current Kubernetes context is pointed at the target cluster.
- The FE CRD exists:
frontendextensions.frontend-forge.kubesphere.io. - The FE controller is installed, usually as the
extension-controllercomponent. - The FE API is installed when using download, publish, unpublish, or delete-with-unpublish HTTP operations.
- The build service configured by
BUILD_SERVICE_BASE_URLis reachable from package Jobs. - Publish target data exists when publishing, normally
ConfigMap/ksbuilder-publish-configinextension-frontend-forge.
Source of truth
Prefer live cluster state for operations and repo docs for expected behavior:

Resource Model
FrontendExtension- cluster-scoped
- short name:
fe - source object for package, artifact, download, publish, and unpublish state
- Package Job
- namespaced
- default namespace:
extension-frontend-forge - typical name:
fe-<fe-name>-package-<artifact-key-12>-a<attempt>
- Artifact ConfigMap
- namespaced
- default namespace:
extension-frontend-forge - referenced by
status.artifact.storage.ref - contains
binaryData["package.tgz"],data["artifact.json"], anddata["files.json"]
- Publish or unpublish Job
- namespaced
- default namespace:
extension-frontend-forge - typical names:
fe-<fe-name>-publish-<request-id-hash-short>fe-<fe-name>-unpublish-<request-id-hash-short>
- Publish target
ConfigMaporSecret- default chart target is usually
ConfigMap/ksbuilder-publish-configin the release namespace
Default names and namespaces can change through Helm values and controller environment variables. Use FE status, Job labels, and controller deployment env vars before assuming defaults.
Common Commands
Inspect FE:
kubectl get fe <name> -o yaml
kubectl get fe <name> -o jsonpath='{.status}{"\n"}'
kubectl get fe <name> -o jsonpath='{.status.phase}{" "}{.status.publish.phase}{" "}{.status.unpublish.phase}{"\n"}'
kubectl get fe -l frontend-forge.kubesphere.io/package-state=ready
kubectl get fe -l frontend-forge.kubesphere.io/publish-state=published
Create or update:
kubectl apply -f <file.yaml>
kubectl apply -f config/samples/frontendextension-inspecttask.yaml
Find package Job and logs:
kubectl get fe <name> -o jsonpath='{.status.packageJob.namespace}{" "}{.status.packageJob.name}{"\n"}'
kubectl -n <job-namespace> get job <job-name> -o yaml
kubectl -n <job-namespace> logs job/<job-name>
Find artifact ConfigMap:
kubectl get fe <name> -o jsonpath='{.status.artifact.storage.ref.namespace}{" "}{.status.artifact.storage.ref.name}{" "}{.status.artifact.storage.key}{"\n"}'
kubectl -n <artifact-namespace> get cm <artifact-configmap-name> -o yaml
Force a rebuild:
kubectl annotate fe <name> frontend-forge.kubesphere.io/rebuild-token="$(date +%s)" --overwrite
Inspect publish or unpublish Jobs:
kubectl get jobs -n extension-frontend-forge -l frontend-forge.kubesphere.io/fe-name=<name>
kubectl get fe <name> -o jsonpath='{.status.publish.jobRef.namespace}{" "}{.status.publish.jobRef.name}{"\n"}'
kubectl get fe <name> -o jsonpath='{.status.unpublish.jobRef.namespace}{" "}{.status.unpublish.jobRef.name}{"\n"}'
kubectl -n <job-namespace> logs job/<job-name>
FE API operations:
KS_API=https://<kubesphere-host>
FE_API="$KS_API/kapis/frontend-forge-api.kubesphere.io/v1alpha1/frontendextensions"
curl -fS "$FE_API/<name>"
curl -fS -u "user:password" "$FE_API/<name>" # user runs this if /kapis returns 401/403
curl -fS "$FE_API/<name>/publish" # read publish status only
curl -fS -X POST -H 'Content-Type: application/json' --data '{"requestId":"manual-1","expectedArtifactDigest":"sha256:<digest>"}' "$FE_API/<name>/publish"
curl -fS "$FE_API/<name>/unpublish" # read unpublish status only
curl -fS -X POST -H 'Content-Type: application/json' --data '{"requestId":"manual-unpublish-1"}' "$FE_API/<name>/unpublish"
curl -fS -X POST -H 'Content-Type: application/json' --data '{"unpublish":true}' "$FE_API/<name>/delete"
curl -fS -u "user:password" -X POST -H 'Content-Type: application/json' --data '{"unpublish":true}' "$FE_API/<name>/delete"
curl -fL "$FE_API/<name>/download" -o <name>.tgz
Operating Rules
- Do not use
-nwithkubectl get fe;FrontendExtensionis cluster-scoped. - Use the FE HTTP API for publish, unpublish, download, and delete-with-unpublish when available. It validates artifact readiness, publish target, digest expectations, and idempotency.
- For KubeSphere users, prefer
/kapis/frontend-forge-api.kubesphere.io/v1alpha1/frontendextensions; use direct service port-forwarding mainly for local debugging. - If
/kapisreturns401or403, guide the user to runcurl -u "user:password" ...or use their normal KubeSphere authenticated session. Do not ask them to paste credentials into the conversation. - Treat publish and unpublish annotations as implementation details written by the FE API. Inspect them for debugging, but do not make raw annotation patches the default workflow.
- Directly patch publish/unpublish annotations only as a last-resort recovery step when the API is unavailable and the operator explicitly accepts the risk. Missing or stale generation, source hash, artifact digest, or target annotations can produce failed publish status.
- Do not expect package creation to publish the extension. Packaging and publishing are separate flows.
- Do not expect direct
kubectl delete fe <name>to unpublish first. Use the FE API delete endpoint with{"unpublish":true}for that behavior. - Treat
status.artifact.artifactKeyas build cache identity, not package content digest. Usestatus.artifact.digestfor the generated package digest. - Treat artifact ConfigMaps as controller-owned outputs. Read them for inspection, but do not edit or delete the ConfigMap referenced by
status.artifact.storage.refunless the user has explicitly requested artifact cleanup and you have confirmed it is not the current artifact.
Safety Rules
Destructive operations:
- Before deleting an FE, check
.status.publish.phase,.status.publish.active, and.status.publish.artifactDigest. - If a published extension should be removed, use the FE API delete endpoint with
{"unpublish":true}so the controller can unpublish before deleting. - Avoid
kubectl delete fe <name>for published extensions unless the user explicitly wants to skip unpublish. - Before deleting Jobs or artifact ConfigMaps, verify owner refs, labels, and whether FE status still references them.
Rebuild:
- Rebuild changes artifact cache identity and can make a previously published artifact stale. Before setting
frontend-forge.kubesphere.io/rebuild-token, record current.status.observedSourceHash,.status.artifact.digest,.status.artifact.artifactKey,.status.publish, andfrontend-forge.kubesphere.io/publish-fresh. - Prefer a unique rebuild token, such as a timestamp or incident id, and use
--overwrite. - After rebuild, verify the new package reaches
Ready; republish only after confirming the newstatus.artifact.digest.
Artifact ConfigMap:
- Use the FE API download endpoint for package bytes when possible; it checks phase, download readiness, source hash, storage kind, and digest.
- Do not mutate
binaryData["package.tgz"],data["artifact.json"], ordata["files.json"]in place. A manual edit can make status, annotations, and digest disagree. - Do not delete the ConfigMap named by
.status.artifact.storage.refduring normal troubleshooting. If cleanup is requested, first confirm the current FE artifact points somewhere else or the FE itself is being deleted.
Status Fields To Check
FE package state:
.status.phase.status.observedGeneration.status.observedSourceHash.status.observedRebuildToken.status.conditions.status.packageJob.status.artifact.status.download
Publish state:
.status.publish.phase.status.publish.active.status.publish.requestId.status.publish.artifactDigest.status.publish.jobRef.status.publish.lastError.status.unpublish.phase.status.unpublish.requestId.status.unpublish.extensionName.status.unpublish.jobRef.status.unpublish.lastError
Labels used for filtering:
frontend-forge.kubesphere.io/package-state:packaging,ready,failedfrontend-forge.kubesphere.io/publish-state:not-published,publishing,published,failedfrontend-forge.kubesphere.io/publish-fresh:true,false
Status consistency with implementation:
- FE package phase is only
Pending,Packaging,Ready, orFailed. - Package Job phase is
Pending,Running,Succeeded, orFailed. - Publish phase is
NotRequested,Pending,Running,Succeeded, orFailed. - Unpublish phase is
NotRequested,Pending,Running,Succeeded, orFailed. - Controller condition types are
SourceValid,ArtifactReady,DownloadReady, andPublishSucceeded. PublishFailedappears as aPublishSucceededcondition reason whenstatus.publish.phase=Failed; it is not a top-level FE phase.
Troubleshooting Order
- Inspect the FE object and status first.
- If package state is not
Ready, inspectstatus.conditions,status.packageJob, package Job logs, build-service reachability, and artifact ConfigMap state. - If package state is
Readybut download fails, inspectstatus.download,status.artifact.storage, the artifact ConfigMap key, and digest consistency. - If publish or unpublish fails, inspect
status.publishorstatus.unpublish, publisher Job logs, target ConfigMap or Secret contents, and API responses. Use annotations as diagnostic evidence, not as the primary operation path. - If live behavior differs from expected defaults, inspect controller deployment env vars and Helm values before changing the FE.
Controller Logs
When status and Job logs are insufficient:
kubectl -n extension-frontend-forge logs deploy/frontend-forge-extension-controller --tail=200
kubectl -n extension-frontend-forge logs deploy/frontend-forge-extension-api --tail=200
Deployment names can vary by Helm release name. If those commands fail, list deployments with:
kubectl -n extension-frontend-forge get deploy -l app.kubernetes.io/component=extension-controller
kubectl -n extension-frontend-forge get deploy -l app.kubernetes.io/component=extension-api
