Project Platform Services

Kommander can also deploy services from a catalog of current cloud native services with the push of a button. This helps organizations quickly deploy services to multiple clusters. Governance-based access to data services ensures roles and responsibilities are maintained. Some of these services are Certified services, which means that you can subscribe to support for them from Kommander.

Kommander can be extended with the AddonRepository resource that point to git repositories containing application addons. For example, the kubeaddons-enterprise repo contains addons such as Jenkins and Kafka with specific settings for each cloud provider. Addons can be composed using either Helm V2 charts or KUDO operators.

Example AddonRepository resource to add a new repository to your catalog:

apiVersion: kubeaddons.mesosphere.io/v1beta1
kind: AddonRepository
metadata:
  name: kubeaddons-enterprise
  namespace: project-namespace
spec:
  priority: "20"
  ref: “stable-1.16”
  url: https://github.com/mesosphere/kubeaddons-enterprise

To deploy an addon:

1. Select Workspace > Project
2. Select View Catalog to browse the available addons from your configured repositories.
3. Select your desired addon.
4. Select the version you’d like to deploy from the version drop-down, and then select Deploy.

For all addons, you must provide a display name and an ID. The ID will be automatically generated based on what is entered for the display name, unless or until you edit the ID directly. The ID must be compliant with Kubernetes DNS subdomain name validation rules.

Optionally, you can customize the helm chart values or KUDO parameters of a service before deploying it.

For Helm-based addons, specify the chart values in a YAML editor:

For KUDO-based addons, fill out the form fields supported by that addon’s parameters schema:

After an addon is deployed in a project, the service is installed to all clusters in that project.

Since a project Platform Service is simply a Kubernetes FederatedAddon, it can also be created using kubectl:

cat << EOF | kubectl create -f -
apiVersion: types.kubefed.io/v1beta1
kind: FederatedAddon
metadata:
  name: jenkins
  namespace: ${projectns}

        values: |

            installPlugins:

              - kubernetes:1.18.2
              - workflow-job:2.33
              - workflow-aggregator:2.6
              - credentials-binding:1.19
              - git:3.11.0
            csrf:
              defaultCrumbIssuer:
                enabled: false
                proxyCompatability: false
            serviceType: "ClusterIP"
            jenkinsUriPrefix: "/jenkins"
            ingress:
              enabled: true
              path: /jenkins
              annotations:
                kubernetes.io/ingress.class: traefik
        version: 1.9.4
EOF

You need to make sure the projectns variable is set before executing the command.

Then, if you run the following command on a Kubernetes cluster associated with the Project, you’ll see a Kubernetes Addon Object, in the corresponding namespace:

$ kubectl -n ${projectns} get addons.kubeaddons.mesosphere.io jenkins -o yaml

kind: Addon

The Konvoy Addon Controller is then responsible for deploying the application.
