Chapter 1. Configuring resource quota or requests With the Argo CD custom resource (CR), you can create, update, and delete resource requests and limits for Argo CD workloads. 1.1. Configuring workloads with resource requests and limits You can create Argo CD custom resource workloads with resource requests and limits. This is required when you want to deploy the Argo CD instance in a namespace that is configured with resource quotas. The following Argo CD instance deploys the Argo CD workloads such as Application Controller , ApplicationSet Controller , Dex , Redis , Repo Server , and Server with resource requests and limits. You can also create the other workloads with resource requirements in the same manner. apiVersion: argoproj.io/v1beta1 kind: ArgoCD metadata: name: example spec: server: resources: limits: cpu: 500m memory: 256Mi requests: cpu: 125m memory: 128Mi route: enabled: true applicationSet: resources: limits: cpu: '2' memory: 1Gi requests: cpu: 250m memory: 512Mi repo: resources: limits: cpu: '1' memory: 512Mi requests: cpu: 250m memory: 256Mi dex: resources: limits: cpu: 500m memory: 256Mi requests: cpu: 250m memory: 128Mi redis: resources: limits: cpu: 500m memory: 256Mi requests: cpu: 250m memory: 128Mi controller: resources: limits: cpu: '2' memory: 2Gi requests: cpu: 250m memory: 1Gi 1.2. Patching Argo CD instance to update the resource requirements You can update the resource requirements for all or any of the workloads post installation. Procedure Update the Application Controller resource requests of an Argo CD instance in the Argo CD namespace. oc -n argocd patch argocd example --type='json' -p='[{"op": "replace", "path": "/spec/controller/resources/requests/cpu", "value":"1"}]' oc -n argocd patch argocd example --type='json' -p='[{"op": "replace", "path": "/spec/controller/resources/requests/memory", "value":"512Mi"}]' 1.3. Removing resource requests You can also remove resource requirements for all or any of your workloads after installation. Procedure Remove the Application Controller resource requests of an Argo CD instance in the Argo CD namespace. oc -n argocd patch argocd example --type='json' -p='[{"op": "remove", "path": "/spec/controller/resources/requests/cpu"}]' oc -n argocd argocd patch argocd example --type='json' -p='[{"op": "remove", "path": "/spec/controller/resources/requests/memory"}]'
