NooBaa Operator

NooBaa is an object data service for hybrid and multi cloud environments. NooBaa runs on kubernetes, provides an S3 object store service (and Lambda with bucket triggers) to clients both inside and outside the cluster, and uses storage resources from within or outside the cluster, with flexible placement policies to automate data use cases.

Usage

Install latest operator CLI (or pick from the releases page):

OS="linux"
# or
OS="mac"

VERSION=$(curl -s https://api.github.com/repos/noobaa/noobaa-operator/releases/latest | jq -r '.name')
curl -LO https://github.com/noobaa/noobaa-operator/releases/download/$VERSION/noobaa-$OS-$VERSION
chmod +x noobaa-$OS-$VERSION
mv noobaa-$OS-$VERSION /usr/local/bin/noobaa

Install with Mac Homebrew:

brew install noobaa/noobaa/noobaa

Install NooBaa to Kubernetes:

# Prepare namespace and set as current (optional)
kubectl create ns noobaa
kubectl config set-context --current --namespace noobaa

# Install the operator and system on your cluster:
noobaa install

# You can always get system status and information with:
noobaa status

Notes:

• Help: noobaa --help
• kubeconfig: - same as kubectl - The CLI operates on the current context from kubeconfig which can be changed with export KUBECONFIG=/path/to/custom/kubeconfig or use the --kubeconfig and --namespace flags.
• minikube: use noobaa install --mini in order to allocate less resources.
• Uninstalling: noobaa uninstall

The CLI helps with most management tasks and focuses on ease of use for manual operations or scripts.

Here is the top level usage:

$ noobaa --help

Troubleshooting

• Verify that there are enough resources for noobaa pods:
  • kubectl describe pod | less
  • kubectl get events --sort-by .metadata.creationTimestamp
• Make sure that there is a single default storage class:
  • kubectl get sc
  • or specify which storage class to use with noobaa install --db-storage-class XXX --pv-pool-default-storage-class YYY
