Migrating from Heptio Ark to Velero

As of v0.11.0, Heptio Ark has become Velero. This means the following changes have been made:

The ark CLI client is now velero.
The default Kubernetes namespace and ServiceAccount are now named velero (formerly heptio-ark).
The container image name is now gcr.io/heptio-images/velero (formerly gcr.io/heptio-images/ark).
CRDs are now under the new velero.io API group name (formerly ark.heptio.com).

The following instructions will help you migrate your existing Ark installation to Velero.

Prerequisites

Ark v0.10.x installed. See the v0.10.x upgrade instructions to upgrade from older versions.
kubectl installed.
cluster-admin permissions.

Migration process

At a high level, the migration process involves the following steps:

Scale down the ark deployment, so it will not process schedules, backups, or restores during the migration period.
Create a new namespace (named velero by default).
Apply the new CRDs.
Migrate existing Ark CRD objects, labels, and annotations to the new Velero equivalents.
Recreate the existing cloud credentials secret(s) in the velero namespace.
Apply the updated Kubernetes deployment and daemonset (for restic support) to use the new container images and namespace.
Remove the existing Ark namespace (which includes the deployment), CRDs, and ClusterRoleBinding.

These steps are provided in a script here:

kubectl scale --namespace heptio-ark deployment/ark --replicas 0
 OS=$(uname | tr '[:upper:]' '[:lower:]') # Determine if the OS is Linux or macOS
 ARCH="amd64"

# Download the velero client/example tarball to and unpack
curl -L https://github.com/vmware-tanzu/velero/releases/download/v0.11.0/velero-v0.11.0-${OS}-${ARCH}.tar.gz --output velero-v0.11.0-${OS}-${ARCH}.tar.gz
tar xvf velero-v0.11.0-${OS}-${ARCH}.tar.gz

# Create the prerequisite CRDs and namespace
kubectl apply -f config/common/00-prereqs.yaml

# Download and unpack the crd-migrator tool
curl -L https://github.com/vmware/crd-migration-tool/releases/download/v1.0.0/crd-migration-tool-v1.0.0-${OS}-${ARCH}.tar.gz --output crd-migration-tool-v1.0.0-${OS}-${ARCH}.tar.gz
tar xvf crd-migration-tool-v1.0.0-${OS}-${ARCH}.tar.gz

# Run the tool against your cluster.
./crd-migrator \
    --from ark.heptio.com/v1 \
    --to velero.io/v1 \
    --label-mappings ark.heptio.com:velero.io,ark-schedule:velero.io/schedule-name \
    --annotation-mappings ark.heptio.com:velero.io \
    --namespace-mappings heptio-ark:velero


# Copy the necessary secret from the ark namespace
kubectl get secret --namespace heptio-ark cloud-credentials --export -o yaml | kubectl apply --namespace velero -f -

# Apply the Velero deployment and restic DaemonSet for your platform
## GCP
#kubectl apply -f config/gcp/10-deployment.yaml
#kubectl apply -f config/gcp/20-restic-daemonset.yaml
## AWS
#kubectl apply -f config/aws/10-deployment.yaml
#kubectl apply -f config/aws/20-restic-daemonset.yaml
## Azure
#kubectl apply -f config/azure/00-deployment.yaml
#kubectl apply -f config/azure/20-restic-daemonset.yaml

# Verify your data is still present
./velero get backup
./velero get restore

# Remove old Ark data
kubectl delete namespace heptio-ark
kubectl delete crds -l component=ark 
kubectl delete clusterrolebindings -l component=ark
