barmyard opened a new issue #2218:
URL: https://github.com/apache/camel-k/issues/2218
I want to pause and start Integrations by scaling the replicas to 0 and 1.
When scaling integrations using `kubectl scale`, Kamelet ConfigMaps are
removed. This breaks the integration.
`timed-logger.yaml` Integration:
```yaml
- from:
uri: "timer:tick?period=15s"
steps:
- to: "kamelet:logger?message=hello"
```
`logger` Kamelet:
```yaml
apiVersion: camel.apache.org/v1alpha1
kind: Kamelet
metadata:
name: logger
labels:
camel.apache.org/kamelet.type: "sink"
spec:
definition:
title: "Logger"
description: |-
Logger
required:
- message
properties:
message:
title: Message
description: Message
type: string
flow:
from:
uri: "kamelet:source"
steps:
- log: "{{message}}"
```
Steps to reproduce:
1. `kamel run timed-logger.yaml`.
ConfigMaps
```
timed-logger-kamelet-logger-flow
timed-logger-source-000
timed-logger-application-properties
```
2. `kubectl scale it timed-logger --replicas 0`
ConfigMaps:
```
timed-logger-source-000
timed-logger-application-properties
```
(`timed-logger-kamelet-logger-flow ` is deleted)
Scaling the integration to 2 results in the same behavior, the Kamelet
ConfigMap is removed.
3. `kubectl scale it timed-logger --replicas 1`
ConfigMaps:
```
timed-logger-source-000
timed-logger-application-properties
```
Log of the `camel-k-operator`:
```
