K8up is a backup operator that will handle PVC and app backups on a k8s/OpenShift cluster.
Just create a schedule and a credentials object in the namespace you’d like to backup. It’s that easy. K8up takes care of the rest. It also provides a Prometheus endpoint for monitoring.
K8up is currently under heavy development and far from feature complete. But it should already be stable enough for production use.
The docs are WIP: https://vshn.github.io/k8up/
You'll need:
- Minishift or Minikube
- golang installed :) (everything is tested with 1.11.3)
- dep installed
- Your favorite IDE (with a golang plugin)
- docker
- make
If you make changes to the CRD structs you'll need to run code generation. This can be done with make:
cd /project/root
make generate
This creates the client folder and deepcopy functions for the structs. This needs to be run on a local docker instance so it can mount the code to the container.
cd /to/go/project
minishift start
oc login -u system:admin # default developer account doesn't have the rights to create a crd
#The operator has the be run at least once before to create the CRD
go run cmd/operator/*.go -development
#Add a demo backupworker (adjust the variables to your liking first)
kubectl apply -f manifest-examples/baas.yaml
#Add a demo PVC if necessary
kubectl apply -f manifest-examples/pvc.yaml
The container has to exist on the registry in order for the operator to find the correct one.
minishift start
oc login -u developer
docker build -t $(minishift openshift registry)/myproject/baas:0.0.1 .
docker save $(minishift openshift registry)/myproject/baas:0.0.1 > tmp.tar
eval $(minishift docker-env)
docker load -i tmp.tar
rm tmp.tar
docker login -u developer -p $(oc whoami -t) $(minishift openshift registry)
docker push $(minishift openshift registry)/myproject/baas:0.0.1
