# K8up Backup Operator
K8up is a Kubernetes backup operator based on [Restic](https://restic.readthedocs.io) that will handle PVC and application backups on a Kubernetes or 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 production ready. It is used in production deployments since 2019.
## Documentation
The documentation is written in AsciiDoc and published with Antora to [k8up.io](https://k8up.io/).
It's source is available in the `docs/` directory.
Run `make docs-preview` to build the docs and preview changes.
## Contributing
K8up is written using [Kubebuilder](https://github.com/kubernetes-sigs/kubebuilder).
You'll need:
- A running Kubernetes cluster (minishift, minikube, k3s, ... you name it)
- [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
- Go development environment
- Your favorite IDE (with a Go plugin)
- Docker
- `make`
- `sed` (or `gsed` for MacOS)
To run the end-to-end test (e.g. `make e2e-test`), you additionally need:
- `helm` (version 3)
- `jq`
- `yq`
- `node` and `npm`
- `bash` (installed, doesn't have to be your default shell)
- `base64`
- `find`
These are the most common make targets: `build`, `test`, `docker-build`, `run`, `kind-run`.
Run `make help` to get an overview over the relevant targets and their intentions.
You can find the project roadmap at [k8up.io](https://k8up.io/k8up/about/roadmap.html).
We use [Snyk](https://snyk.io/test/github/k8up-io/k8up) to test the code regularly for vulnerabilities and other security issues.
If you find any security issue, please follow our [Vulnerability Reporting](https://k8up.io/k8up/about/vulnerability_reporting.html) process.
### Code Structure
K8s consists of two main modules:
- The _operator_ module is the part that runs constantly within K8s and contains the various reconciliation loops.
- The _restic_ module is our interface to the `restic` binary and is invoked whenever a `Backup` or `Restore` (or similar) custom resource is instantiated.
If it's job (like doing a backup or a restore) is done, the process ends.
```asciidoc
/
- api Go Types for the Custom Resource Definitions (CRDs) [o]
- cmd CLI definition and entrypoints
- common Code that is not specific to either
- config Various configuration files for the Operator SDK [o]
- controllers The reconciliation loops of the operator module [o]
- docs Out ASCIIdoc code as published on https://k8up.io
- e2e The Bats-based End-To-End tests
- envtest Infrastructure code for the integration tests
- operator Code that is otherwise related to the _operator module_,
but not part of the recommended Operator SDK structure.
- restic Code that makes up the _restic module_.
[o]: this is part of the recommended Operator SDK structure
```
### Generate Kubernetes code
If you make changes to the CRD structs you'll need to run code generation.
This can be done with make:
```bash
make generate
```
### Install CRDs
CRDs can be either installed on the cluster by running `make install` or using `kubectl apply -f config/crd/apiextensions.k8s.io/v1`.
Currently there's an issue using [`make install`](https://github.com/kubernetes-sigs/kubebuilder/issues/1544) related to how the CRDs are specified.
Therefore settle to the second approach for now.
### Run the operator
You can run the operator in different ways:
1. as a container image (see [quickstart](https://sdk.operatorframework.io/docs/building-operators/golang/quickstart/))
2. using `make run-operator` (provide your own kubeconfig)
3. using `make kind-run` (uses KIND to install a cluster in docker and provides its own kubeconfig in `testbin/`)
4. using a configuration of your favorite IDE
Best is if you have [minio](https://min.io/download) installed somewhere to be able to setup the needed env values. It needs to be reachable from within your dev cluster.
### Run E2E tests
You need `node` and `npm` to run the tests, as it runs with [DETIK][detik].
To run e2e tests, execute:
```bash
make e2e-test
```
To test just a specific e2e test, run:
```bash
make e2e-test -e BATS_FILES=test-02-deployment.bats
```
To remove the local KIND cluster and other e2e resources, run:
```bash
make e2e-clean
```
To cleanup all created artifacts, there's always:
```bash
make clean
```
### Example configurations
There are a number of example configurations in [`config/samples`](config/samples).
Apply them using `kubectl apply -f config/samples/somesample.yaml`
