Kubernetes Apply

Apply Kubernetes manifests directly to the cluster without using a managed release strategy.

Deploy a subset of pods with the new version alongside the stable version for validation before a full rollout.

Switch Kubernetes service selectors to route production traffic to the new pod set after a blue-green deploy.

Prepare manifests, apply them to the cluster, and wait for all pods to reach steady state.

Delete Kubernetes resources by name, manifest path, or release name.

Wait for Kubernetes workloads to reach a healthy running state after a deployment or scale operation.

Re-apply the previous release manifests to roll back a failed rolling or canary deployment.

Compare the current state of the cluster with the desired state defined in your manifests.

Shift traffic between service versions using Istio VirtualServices or Kubernetes Gateway API HTTPRoutes.

Scale a Kubernetes workload to a specific number of instances or a percentage of current instances.

Deploy the new version to the stage pod set and wait for it to reach steady state before a traffic swap.

Modify a specific Kubernetes workload in place without redeploying the full manifest.

Validate Kubernetes manifests against the cluster without applying changes.

Run kubectl rollout subcommands against Kubernetes workloads identified by name, manifest path, or release name.

Remove the canary workload after validation or on rollback.

Clean up the old pod set after a successful blue-green swap to free cluster resources.
