| # Destroy Cluster | ||
|
|
||
| This command is used for destroy CRDS (custom resource definitions) created by rook-ceph | ||
|
|
||
| ## !!! Warning !!! | ||
| **This command is not reversible**, and it will destroy your rook-ceph cluster completely and your data, | ||
| please only use this command if your sure that your data must be destroyed. | ||
|
|
||
| ## How to use: | ||
|
|
||
| Just you need to run the command, and you will be asked for the confirmation | ||
| ```bash | ||
| $ kubectl rook-ceph -n rook-ceph destroy-cluster | ||
| Are you sure you want to destroy the cluster in namespace "rook-ceph"? | | ||
| ``` | ||
|
|
||
| You must write exactly this answer **yes-really-destroy-cluster** | ||
| to confirm that you really want to execute the command and destroy | ||
| your cluster, any other response will be rejected and | ||
| the process will be stopped even responding yes | ||
|
|
||
| ```bash | ||
| $ kubectl rook-ceph -n rook-ceph destroy-cluster | ||
| Are you sure you want to destroy the cluster in namespace "rook-ceph"? yes | ||
| Error: you need to response "yes-really-destroy-cluster" to confirm the cluster deletion | ||
| exit status 1 | ||
|
|
||
| ``` | ||
|
|
||
| Once you respond with the right answer the process will start, and it will be deleteing the CRDS created by rook-ceph | ||
|
|
||
| ```bash | ||
| $ kubectl rook-ceph -n rook-ceph destroy-cluster | ||
| Warning: Are you sure you want to destroy the cluster in namespace "rook-ceph"? | ||
| yes-really-destroy-cluster | ||

| # Developer changes | ||
| We are adding unittests in order to ensure that the destroy-cluster command is working as we expected, | ||
| so if you want to expand the functionality, and you need to change the `pgk/k8sutil/interface.go` remember to recreate the mocks by using `make generate` | ||
|
|
||
| ```bash | ||
| $ make generate | ||
| generating mocks... | ||
| completed | ||
| $ | ||
| ``` | ||
|
|
||
| # Run test | ||
|
|
||
| To run the tests you should to execute `make test` | ||
| ```bash | ||
| $ make test | ||
| running unit tests | ||
| go test ./... | ||
