Removing Jaeger

The steps for removing Jaeger from an OpenShift Container Platform cluster are as follows:

  1. Shut down any Jaeger pods.

  2. Remove any Jaeger instances.

  3. Remove the Jaeger Operator.

Removing a Jaeger instance using the web console

When deleting an instance that uses the in-memory storage, all data will be permanently lost. Data stored in a persistent storage (such as Elasticsearch) will not be deleted when a Jaeger instance is removed.
Procedure

  1. Log in to the OpenShift Container Platform web console.

  2. Navigate to Operators → Installed Operators.

  3. Select the name of the project where the Operators are installed from the Project menu, for example, jaeger-system.

  4. Click the Jaeger Operator.

  5. Click the Jaeger tab.

  6. Click the Options menu kebab next to the instance you want to delete and select Delete Jaeger.

  7. In the confirmation message, click Delete.

Removing a Jaeger instance from the CLI

  1. Log in to the OpenShift Container Platform CLI.

    $ oc login

  2. To display the Jaeger instances run the command:

    $ oc get deployments -n <jaeger-project>

    The names of operators have the suffix -operator. The following example shows two Jaeger Operators and four Jaeger instances:

    $ oc get deployments -n jaeger-system

    You should see output similar to the following:

    NAME                     READY   UP-TO-DATE   AVAILABLE   AGE
elasticsearch-operator   1/1     1            1           93m
jaeger-operator          1/1     1            1           49m
jaeger-test              1/1     1            1           7m23s
jaeger-test2             1/1     1            1           6m48s
tracing1                 1/1     1            1           7m8s
tracing2                 1/1     1            1           35m

  3. To remove an instance of Jaeger, run the command:

    $ oc delete jaeger <deployment-name> -n <jaeger-project>

    For example,

    $ oc delete jaeger tracing2 -n jaeger-system

  4. To verify the deletion, run oc get deployment again:

    $ oc get deployments -n <jaeger-project>

    For example,

    $ oc get deployments -n jaeger-system

    Should generate output similar to the following:

    NAME                     READY   UP-TO-DATE   AVAILABLE   AGE
elasticsearch-operator   1/1     1            1           94m
jaeger-operator          1/1     1            1           50m
jaeger-test              1/1     1            1           8m14s
jaeger-test2             1/1     1            1           7m39s
tracing1                 1/1     1            1           7m59s

Removing the Jaeger Operator

Procedure

  1. Follow the instructions for Deleting Operators from a cluster.

    • Remove the Jaeger Operator.

    • After the Jaeger Operator has been removed, if appropriate, remove the Elasticsearch Operator.
