Prism Install

Prism is installed using a Helm chart. During Helm chart deployment, Prism resources are created:

1. API deployment and services
2. UI deployment
3. Prism namespace
4. Action config maps
5. Builtin substitutions
6. Status mappings

Prism namespace

All prism Kubernetes resources are created in the prism namespace. The prism namespace is built equivalent to issuing this command:

kubectl create namespace prism 

Builtin Substitutions

Builtin subsitutions are created in config map 'builtin' in the prism namespace:

apiVersion: v1
kind: ConfigMap
metadata:
   name: builtin
   namespace: prism
data:
   icp_console_url: "<ICP console URL>"
   kibana_url: "<Kibana URL>"
   liberty_log_dashboard_prefix: "Liberty-Problems-K5-" 
   liberty_log_dashboard_name: "<Liberty Kibana dashboard name>" 

Internal details

1. icp_console_url is obtained from TBD

2. kibana_url is obtained by looking up the host and nodeport of the service named 'kibana'.

3. liberty_log_dashboard_prefix specifies the static portion of the Liberty Kibana dashboard name. The full name includes a release date.

4. liberty_log_dashboard_name is obtained by searching for an "id" that starts with the liberty_log_dashboard_prefix in the output from the following API invocation:

   ${kibana_url}/api/saved_objects/dashboard

   The output:

   {"saved_objects":
      [
         {"id":"Liberty-Problems-K5-20180315","type":"dashboard","version":1, ... }
      ]
   }
