Rancher Partner Charts is a collection of Helm charts from SUSE partners that are certified to run on Rancher-supported Kubernetes distributions. These charts are served from this repository so that users can deploy these charts directly from the Apps view in Rancher Manager.
Rancher-specific modifications are applied to these charts, and overlay files may be added as well.
Before submitting a contribution to this repository, you must be a SUSE "Ready" Verified partner.
Start this process with a Partner Application.
To certify your software, you need to attest that the software:
- has been tested on RKE2 or K3s and publishes documentation showing supported
versions, including
- version of Rancher (e.g. 2.8)
- Rancher-supported distribution of Kubernetes (RKE2, K3s, EKS, etc.)
- version of Kubernetes (e.g. 1.27)
- is supported by your organization on the declared Rancher versions and configurations
- is actively maintained and proactively updated
- Critical vulnerabilities are patched in a timely way
- release notes disclose serious bugs and vulnerabilities
- has a license and/or terms and conditions for use available in public documentation or via the chart itself
- does not compete commercially with Rancher Prime
Once your software is certified SUSE "Ready", there are a few more requirements for inclusion in Rancher Partner charts. The Helm chart must:
- be Helm 3 compatible
- be in a hosted Helm (recommended) or Git repository that we can reference
- have the following Rancher specific add-ons (More details on this below)
- kubeVersion set in the chart's metadata
- app-readme.md
- questions.yml (Optional)
- be deployable from the current version of Rancher with the default Values
Testing these requirements will ensure that Rancher users can deploy your software correctly and easily.
1. Fork the Rancher Partner Charts repository, clone your fork, checkout the main-source branch and pull the latest changes.
Then create a new branch off of main-source
cd partner-charts
mkdir -p packages/suse/kubewarden-controller
3. Create your upstream.yaml in packages/<vendor>/<chart>
The tool reads a configuration yaml, upstream.yaml
, to know where to fetch the upstream chart. This file is also able to define any alterations for valid variables in the Chart.yaml as described by Helm.
Important: In GKE clusters, a Helm Chart will NOT display in Rancher Apps unless kubeVersion
includes -0
suffix in Chart.yaml
For example:
kubeVersion: '>= 1.19.0-0'
Some example upstream.yaml are provided below
cat <<EOF > packages/suse/kubewarden-controller/upstream.yaml
HelmRepo: https://charts.kubewarden.io
HelmChart: kubewarden-controller
Vendor: SUSE
DisplayName: Kubewarden Controller
ChartMetadata:
icon: https://www.kubewarden.io/images/icon-kubewarden.svg
EOF
Create any add-on files such as an app-readme.md
and questions.yml
in an overlay
subdirectory (Optional)
mkdir packages/suse/kubewarden-controller/overlay
echo "Example app-readme.md" > packages/suse/kubewarden-controller/overlay/app-readme.md
git add packages/suse/kubewarden-controller
git commit -m "Submitting suse/kubewarden-controller"
git push origin <your_branch>
If you would like to test your configuration using the CI tool, simply run the provided script in scripts/pull-scripts
to download the binary. The 'auto' function is what will be run to download and store your chart.
scripts/pull-scripts
You can confirm the package entry with bin/partner-charts-ci list
which will list all detected charts with a configuration file.
export PACKAGE=<vendor>/<chart>
The 'auto' subcommand will run the complete CI process. The 'stage' subcommand will do the same process but will not create a git commit when it completes.
bin/partner-charts-ci auto
bin/partner-charts-ci validate
- If you haven't done so yet, pull down your new chart files into your local
partner-charts
repository:
a) Get scripts: scripts/pull-scripts
b) List and find your company name/chart: bin/partner-charts-ci list | grep <vendor>
c) set PACKAGE variable to your company/chart: export PACKAGE=<vendor>/<chart-name> or export PACKAGE=<vendor>
d) Run bin/partner-charts-ci stage or auto # the new charts should be downloaded
- In your local
partner-charts
directory start a python3 http server:
#python3 -m http.server 8000
- From a second terminal expose your local http server via ngrok ( https://ngrok.com/download )
#./ngrok http 8000
-
In Rancher UI create a test repository that points to your local
partner-charts
repo by selecting an appropriate cluster and going to Apps > Repositories and clicking "Create". Enter a Name, copy ngrok forwarding url and paste it into Target http(s) "Index URL" and click "Create" again. -
Once the new repository is "Active" go to Apps > Charts , find your new chart, review Readme is correct, etc. and install it. It should be successfully deployed.
Any files placed in the packages/<vendor>/<chart>/overlay
directory will be overlayed onto the chart. This allows for adding or overwriting files within the chart as needed. The primary intended purpose is for adding the optional app-readme.md and questions.yml files but it may be used for adding or replacing any chart files.
-
app-readme.md
- Write a brief description of the app and how to use it. It's recommended to keep it short as the longerREADME.md
in your chart will be displayed in the UI as detailed description. -
questions.yml
- Defines a set of questions to display in the chart's installation page in order for users to answer them and configure the chart using the UI instead of modifying the chart's values file directly.
questions:
- variable: password
default: ""
required: true
type: password
label: Admin Password
group: "Global Settings"
- variable: service.type
default: "ClusterIP"
type: enum
group: "Service Settings"
options:

- "NodePort"
- "LoadBalancer"
required: true
label: Service Type
show_subquestion_if: "NodePort"
subquestions:

description: "NodePort port number (to set explicitly, choose port between 30000-32767)"
type: int
min: 30000
max: 32767

These steps are for charts still using package.yaml
to track upstream chart. These charts should be migrated to receive automatic updates via an upstream.yaml
by following the steps below. After chart is migrated, it should get updated from your helm/github repo automatically.
1. Fork partner-charts repository, clone your fork, checkout the main-source branch and pull the latest changes. Then create a new branch off of main-source
mkdir -p partner-charts/packages/suse/kubewarden-controller
If your existing chart is using a high patch version like 5.5.100 due to old method of taking version 5.5.1 and modifying it with the PackageVersion, add PackageVersion
to the upstream.yaml
(set it to 01 , 00 is not valid). Ideally, when the the next minor version is released e.g. 5.6.X you can then remove PackageVersion
from the upstream.yaml
since 5.6.X > 5.5.XXX. E.g.
cat <<EOF > packages/suse/kubewarden-controller/upstream.yaml
HelmRepo: https://charts.kubewarden.io
HelmChart: kubewarden-controller
Vendor: SUSE
DisplayName: Kubewarden Controller
PackageVersion: 01 # add if existing chart is using high patch version
ChartMetadata:
kubeVersion: '>=1.21-0'
icon: https://www.kubewarden.io/images/icon-kubewarden.svg
EOF
4. If there is an overlay
dir in partner-charts/packages/<chart>/generated-changes/
move it to packages/<vendor>/<chart>/
and ensure only necessary files are present in overlay dir e.g.
mv partner-charts/packages/kubewarden-controller/generated-changes/overlay partner-charts/packages/suse/kubewarden-controller/
Check the old generated-changes/patch directory for any requisite other changes. If there is an edit in Chart.yaml.patch
that needs to be replicated, it can be handled in the upstream.yaml
ChartMetadata
(see https://github.com/rancher/partner-charts#configuration-file). If it is a change for any other file in the chart it can be done via an overlay file. See https://github.com/rancher/partner-charts#overlay
git rm -r packages/<chart>
git rm -r charts/<chart>
- Note: If a chart is using a logo file in partner-charts repo, make sure the
icon:
variable is set correctly in theupstream.yaml ChartMetadata
.
6. Stage your changes (To make sure the config works, and to setup the new charts and assets directories)
export PACKAGE=<vendor>/<chart>
bin/partner-charts-ci stage
7. Move the old assets files to the new directory (Sometimes this is unchanged but most times it does change)
git mv assets/<chart>/* assets/<vendor>/
sed -i 's%assets/<chart>%assets/<vendor>%' index.yaml
After doing this, run this loop to validate that every assets file referenced in the index actually exists, it makes sure your paths aren't edited incorrectly.
for charts in $(yq '.entries[][] | .urls[0]' index.yaml); do stat ${charts} > /dev/null; if [[ ! $? -eq 0 ]]; then echo ${charts}; fi; done
The command should return quickly with no output. If it outputs anything it means some referenced assets files don't exist which is a problem.
git add assets charts packages index.yaml
git commit -m "Migrating <vendor> <chart> chart"
git push origin <your branch>
Charts may be removed from this repository for a number of reasons:
- Technical requirements are not met
- A serious security problem is discovered
- The vendor's SUSE "Ready" partnership is no longer active
In these cases, the chart will first be deprecated. While a chart is deprecated, no new versions of the chart will be added to this repository. The chart will be left in the deprecated state for a minimum of 3 months, and then it will be removed. The pull requests that deprecate and remove the chart will indicate an alternative source (e.g. the corresponding upstream project or Rancher Prime Application Collection) if one is available.
