For a Kommander management cluster, you can edit appdeployments by editing Helm values in the install.yaml file as this article describes:
However, this process will not work for attached clusters. For those, the best method is to use the DKP UI.
Navigate to the Applications menu on the side panel in the appropriate workspace for the cluster that you are trying to configure. Scroll down to the application that you wish to configure, click the Three Dots, and click Edit.
You will see a configuration menu with an empty text box. This box accepts Helm value YAML overrides for the related application. Here are some common configuration values to serve as examples:
Prometheus Adapter:
resources:
limits:
memory: 4000Mi
Logging Operator:
resources:
limits:
memory: 1024Mi
Grafana-Loki:
gateway:
nginxConfig:
httpSnippet: |-
client_max_body_size 50M;
serverSnippet: |-
client_max_body_size 50M;
Once you've made the appropriate changes, click the Save button in the top right corner to apply them.
