Clone stack configurations from existing clusters or remote repositories. Perfect for replicating production setups to staging or dev environments.

​
Prerequisites

  • Ankra CLI installed and configured
  • A cluster configuration file (YAML)

​
Clone from a Local File

Copy stacks from an existing cluster configuration: 
ankra cluster clone existing-cluster.yaml new-cluster.yaml

​
Clone from GitHub

Pull configurations directly from a repository: 
ankra cluster clone https://github.com/user/repo/raw/main/cluster.yaml my-cluster.yaml

​
Clone Options

FlagDescription
--cleanReplace all stacks in target (clean copy)
--forceOverride conflicts during merge
--copy-missingCopy missing files even from skipped stacks
--stackClone only specific stacks by name (repeatable)
Examples: 
# Clean copy - replace all stacks in target
ankra cluster clone source.yaml target.yaml --clean

# Force merge - override conflicts
ankra cluster clone source.yaml target.yaml --force

# Clone only specific stacks
ankra cluster clone source.yaml target.yaml --stack "monitoring" --stack "networking"

# Complete replacement with all files
ankra cluster clone source.yaml target.yaml --clean --force --copy-missing

​
Example Workflow

1

Clone from GitHub

ankra cluster clone https://github.com/ankraio/ankra-gitops-examples/raw/main/clusters/monitoring-stack/cluster.yaml ./my-cluster.yaml
2

Apply the Configuration

ankra cluster apply -f my-cluster.yaml
3

Customize Values

Edit the YAML file or use the UI to adjust values for your environment (resource limits, domains, replicas).

​
Clone via UI

You can clone stacks directly in the Ankra UI: Clone a single stack:
  1. Navigate to Stacks in your cluster
  2. Click the menu on any stack card
  3. Select Clone to Cluster
  4. Choose a target cluster and click Clone Stack
Clone multiple stacks at once:
  1. Navigate to Stacks in your cluster
  2. Click the Clone Stacks button next to the search bar (or click a stack card’s avatar to start selecting)
  3. Select the stacks you want to clone — a floating action bar shows the count
  4. Click Clone to Cluster, choose a target cluster, and confirm
  5. All selected stacks are cloned as drafts to the target cluster
