Chapter 2. Viewing pipeline logs using the OpenShift Logging Operator

Procedure

1. Log in to OpenShift Container Platform web console as a cluster administrator.
2. In the top right of the menu bar, click the grid icon Observability Logging. The Kibana web console is displayed.

3. Create an index pattern:

   1. On the left navigation panel of the Kibana web console, click Management.
   2. Click Create index pattern.
   3. Under Step 1 of 2: Define index pattern Index pattern, enter a * pattern and click Next Step.
   4. Under Step 2 of 2: Configure settings Time filter field name, select @timestamp from the drop-down menu, and click Create index pattern.

4. Add a filter:

   1. On the left navigation panel of the Kibana web console, click Discover.

   2. Click Add a filter + Edit Query DSL.

      Note
      • For each of the example filters that follows, edit the query and click Save.
      • The filters are applied one after another.

      1. Filter the containers related to pipelines:

         Example query to filter pipelines containers

         {
           "query": {
         	"match": {
           	"kubernetes.flat_labels": {
             	"query": "app_kubernetes_io/managed-by=tekton-pipelines",
             	"type": "phrase"
           	}
         	}
           }
         }

      2. Filter all containers that are not place-tools container. As an illustration of using the graphical drop-down menus instead of editing the query DSL, consider the following approach:

         Figure 2.1. Example of filtering using the drop-down fields

         

      3. Filter pipelinerun in labels for highlighting:

             	"query": "tekton_dev/pipelineRun=",
             	"type": "phrase"
           	}
         	}
           }
         }

             	"query": "tekton_dev/pipeline=",
             	"type": "phrase"
           	}
         	}
           }
         }
