Needs first. Nothing. The script applies any CRDs first.
How it works. How the model works, and Helm in the Catalog.
Pick a version and a base
Versions are listed newest first. Each row is one base, and every cell is read from that base's listing. A base marked watch has a checked result with a limit to review.

See what changes
Choose two versions or two bases, then press Compare. The page fetches the two retained files and checks each file's SHA-256 against the digest its listing records. It then computes the diff on demand, in your browser, with the code that cub config diff runs. Nothing is precomputed or stored.
Run the same diff yourself
These commands fetch the same two files and compare them on your machine, with no account. They follow the pair you choose above. cub plugin install confighub/cub-workshop@v0.6.61 adds cub config diff.

These lines are the only diff content this page stores. Each one was computed when the site was generated, by the same code, on the default base of both versions.
- From 41.0.2 to 41.4.0 on the default base, 13 of 31 objects change. Compute this diff.
- From 40.2.0 to 41.0.2 on the default base, 6 of 31 objects change, 5 are added and 5 are removed. Compute this diff.
Use this entry in ConfigHub
Every Catalog entry page carries these five steps in this order. Each step says what the Catalog has run for this entry, and a step with a missing precondition gives no command.
Steps 1 and 2 need no account. Install the cub CLI before any cub command. Step 2 uses cub config diff, which cub plugin install confighub/cub-workshop@v0.6.61 adds. A live walk on 2026-10-08 ran steps 3 to 5 for bitnami-nginx-24-0-2-http-clusterip and nvidia-gpu-operator-v26-3-3-default. These commands carry the changes that walk needed. It is a dated log and no receipt, so no state on this page rests on it. These are the steps for 41.4.0, the newest version, on its default base.
What is fixed, and what you supply
Fixed when this entry was built. These went into the build, so the objects already carry them. To change one, build the entry again from its source.

Yours to supply or check. The listing records no input for the destination. The Catalog has not ruled one out for your cluster.
This entry's plan, and how to test it
These are the steps that plain objects cannot carry. ConfigHub stores them and does not carry them out. The words in italics say what the Catalog knows about each.
- When you deliver. CRD ordering declaration for the 25 gateway and traefik CRDs. Who: selected destination actor. Written down. Not run by the Catalog.
Test the install steps yourself. This script carries them out with kubectl on a cluster you choose, with no account. Read it first and use a throwaway cluster. The Catalog has no recorded run of this script.
Test the plain objects. A second script tests the retained objects themselves with kubectl, and it needs no cub and no account. The Catalog has no recorded run of this script.
1. Get the exact objects Run for this entry
The Catalog rendered this entry and retains its 31 objects in one file.
An upload can create more Units than the objects counted here. The installer renders a Namespace, and the upload adds an installer-record Unit.
Here is what the command does. cub installer is an open-source plugin for the cub CLI. cub installer setup pulls a catalog package and writes its Kubernetes files locally, leaving delivery to kubectl, Argo CD or Flux. The generated scripts stop before doing any work when the plugin or kustomize is missing.

Compare with another version or base Not run for this entry
The listing records no comparison for this entry. The commands run on the retained files, with no account. The Catalog holds 2 other versions, 40.2.0 and 41.0.2.
# fetch the default base at version 41.0.2
$ curl -fsSL -o traefik-traefik-41-0-2-default.yaml https://raw.githubusercontent.com/confighub/helm-expt/main/recipes/traefik/traefik/41.0.2/revisions/default/r001/rendered/release-objects.yaml

$ cub config diff traefik-traefik-41-0-2-default.yaml traefik-traefik-41-4-0-default.yaml --summary3. Upload it as a variant Not run for this entry
The Catalog has not uploaded this entry. The commands use its signed installer package. Read the log of the live walk on 2026-10-08.
Replace each value in angle brackets with a name of your own. The entry id may already exist as a Space in your organization, and the package name as a Component.
In the live walk, a Space named for the nginx entry's id and a Component named bitnami-nginx already existed, so the walk chose its own names. The --component flag sets the Component label the upload writes on the Space, which is the package name when you omit it.
The cub installer plugin reads your organization from CUB_CONTEXT and ignores --context. If you use a context other than your default, export CUB_CONTEXT first, or the plugin works in your default organization.
# sign in; steps 3 to 5 write to your ConfigHub organization
$ cub auth login
# upload step 1's directory as a Space of Units, under names you choose
$ cub installer upload --work-dir ./traefik-traefik-41-4-0-default --space <your-space> --component <your-component>
# list the Units the upload created
$ cub unit list --space <your-space>4. Deploy it Not run for this entry
No delivery run is recorded for this entry. Argo CD has not run, Flux has not run, and kubectl has not run. The commands name the Target workshop/target, which cub cluster up --name workshop creates on a local kind cluster with Argo CD. Use your own Target for a real destination. Read the log of the live walk on 2026-10-08.
Use the Space name you chose in step 3. The delete command is needed because the cloned installer-record Unit carries the Target and Argo CD v3.5.4 cannot read it, a defect seen on cub v0.8.7 and server v0.8.9.
Without that line the walk deployed nothing and Argo CD showed Unknown, while every cub command exited 0. The walk ran the four commands in this order and did not try them without the first publish.
ConfigHub shows nothing when Argo CD fails to read a Release. Run kubectl -n argocd get applications.argoproj.io and read the Sync column, because Healthy alone is not a pass. Argo CD took between 18 seconds and about 5 minutes to read a Release on a cluster made without argobot.
The walk made its cluster with cub cluster up --no-argobot. That command creates two Spaces, a Worker, a Target and a Trigger, opens ports 30010 to 30019 on the machine, and installs Argo CD from an unpinned upstream manifest.
Removing the ConfigHub side does not remove the workload. In the walk, deleting the Application Unit and the Spaces left the Application and its pods running, because the root Application does not prune.
# clone the base onto a Target as a dev variant
$ cub variant create dev <your-space> --target workshop/target --space-pattern "template:<your-space>-dev"
# publish the Release that the cluster's Argo CD pulls
$ cub release publish <your-space>-dev
# delete the installer record, which Argo CD cannot read
$ cub unit delete --space <your-space>-dev installer-record
# publish again without it
$ cub release publish <your-space>-dev5. Promote a change Not run for this entry
No promotion is recorded for this entry. Promotion carries a change in the base to the dev variant. The base changes when you edit a Unit or upload a newer version into the same Space. Read the log of the live walk on 2026-10-08.
The promotion changes the dev Space and publishes nothing. It also adds the installer-record Unit back with the Target. The change reaches the cluster only after the delete and the publish.
The preview lists the whole installer record as added. In the walk, the preview of a one-label change to gpu-operator ran to 405 lines, and about 400 of them were that record.
# preview what the dev variant would take from the base
$ cub variant promote <your-space>-dev --dry-run -o mutations
# promote once you have read the preview
$ cub variant promote <your-space>-dev --change-desc "Pull the reviewed base forward"
# delete the installer record that the promotion adds back
$ cub unit delete --space <your-space>-dev installer-record
# publish the Release that carries the change
$ cub release publish <your-space>-devUse another version or base
Every other base carries the same five steps, with its own states and commands, on the page of its version.
- The same five steps on the page for 41.0.2 cover the base default.
- The same five steps on the page for 40.2.0 cover the bases default, no-crds.

Technical notes and disclaimers
- The plain-objects script applies the objects and ends. It does not wait for the workloads to start. Neither script runs the steps the plan names for an upgrade or a delete.
