quarks-operator can be installed via
helm. You can use our helm repository.
See the releases page for up-to-date instructions on how to install the operator.
For more information about the
quarks-operator helm chart and how to configure it, please refer to the helm repository README.md. A short summary of the installation steps is presented below.
- Kubernetes cluster
Add the quarks repository to helm if you haven’t already:
The simplest way to install the operator, is by using the default values:
The operator will watch for BOSH deployments in separate namespaces, not the one it has been deployed to. By default, it creates a namespace
staging and starts watching it.
A complete list of the chart settings is available here.
The quarks-operator watches namespaces labeled with
ID has to be specified with helm settings during install (
The helm value setting
global.singleNamespace.name= allows to automatically create a namespace which is being watched by the quarks-operator.
For example, to watch to a different namespace with a specific ID:
Using multiple namespaces with one operator
The cluster role can be reused between namespaces. The service account (and role binding) should be different for each namespace.
Manually create before running helm install, for each namespace:
- a namespace “staging1” with the following labels (note: “cfo” and “qjob-persist-output” are the defaults from values.yaml):
quarks.cloudfoundry.org/monitored: "cfo" quarks.cloudfoundry.org/qjob-service-account: qjob-persist-output
- a service account named “qjob-persist-output”
- a role binding from the existing cluster role “qjob-persist-output” to “qjob-persist-output” service account in namespace “staging1”
For more options look at the README for the chart
With a running
quarks-operator pod, you can try one of the files (see boshdeployment-with-custom-variable.yaml ), as follows (if you installed it with default values):
The above will spawn two pods in your
cf-operator namespace (which needs to be created upfront), running the BOSH nats release.
You can access the
quarks-operator logs by following the operator pod’s output:
Or look at the k8s event log:
Modifying the deployment
The main input to the operator is the
BOSH deployment custom resource and the according manifest config map or secret. Changes to the
Data fields of either of those will trigger the operator to recalculate the desired state and apply the required changes from the current state.
Each creation or update can trigger the creation of multiple pods with the
ig-prefix. Those are warm up jobs, which are preparing manifests and eventually configure the pods your BOSH releases will be running on. When
ig-pods are completed, the pods are ready to start up. See also BOSH deployment status.
Besides that there are more things the user can change which will trigger an update of the deployment:
ops filescan be added or removed from the
BOSH deployment. Existing
ops fileconfig maps and secrets can be modified
- generated secrets for explicit variables can be modified
- secrets for implicit variables have to be created by the user beforehand anyway, but can also be changed after the initial deployment
