Manual Installation

To install Purser manually from the Binary follow the steps described below.

Purser Setup

The following steps will install Purser in your cluster at namespace purser. Creation of this namespace is needed because purser needs to create a service-account which requires namespace. Also, the frontend will use kubernetes DNS to call backend for data and this DNS contains a field for namespace.

# Namespace setup
kubectl create ns purser

# DB setup
curl https://raw.githubusercontent.com/vmware/purser/master/cluster/purser-database-setup.yaml -O
kubectl --namespace=purser create -f purser-database-setup.yaml

# Purser controller setup
curl https://raw.githubusercontent.com/vmware/purser/master/cluster/purser-controller-setup.yaml -O
kubectl --namespace=purser create -f purser-controller-setup.yaml

# Purser UI setup
curl https://raw.githubusercontent.com/vmware/purser/master/cluster/purser-ui-setup.yaml -O
kubectl --namespace=purser create -f purser-ui-setup.yaml

NOTE: If you don't have curl installed you can download purser-database-setup.yaml from here, purser-controller-setup.yaml from here and purser-ui-setup.yaml from here. Then kubectl create -f purser-database-setup.yaml , kubectl create -f purser-controller-setup.yaml and kubectl create -f purser-ui-setup.yaml will setup purser in your cluster.

Change Settings and Enable/Disable Purser Features

The following settings can be customized before Controller installation:

  • Change the default log level, dgraph url and dgraph port by editing args field in the purser-controller-setup.yaml. (Default: --log=info, --dgraphURL=purser-db, --dgraphPort=9080)
  • Enable/Disable resource interactions capability by editing args field in the purser-controller-setup.yaml and uncommenting pods/exec rule from purser-permissions. (Default: disabled)
  • Enable subscription to inventory changes capability by creating an object of custom resource kind Subscriber. (Refer: example-subscriber.yaml)
  • Enable customized logical grouping of resources by creating an object of custom resource kind Group. (Refer: docs for custom group installation and usage)

NOTE: Use flag --kubeconfig=<absolute path to config> if your cluster configuration is not at the default location.

Purser Plugin Installation (Optional)

  • Download the purser plugin descriptor for your environment from the releases page.

  • Move the plugin.yaml file into one of the paths specified under the Kubernetes documentation.

  • Download the purser binary corresponding to your operating system from the releases page.

  • Move the binary into one of the directories in your environment PATH.
