## Example
|
|
|
|
When Heptio Ark finishes a Restore, its status changes to "Completed" regardless of whether or not there are issues during the process. The number of warnings and errors are indicated in the output columns from `ark restore get`:
|
|
|
|
```
|
|
NAME BACKUP STATUS WARNINGS ERRORS CREATED SELECTOR
|
|
backup-test-20170726180512 backup-test Completed 155 76 2017-07-26 11:41:14 -0400 EDT <none>
|
|
backup-test-20170726180513 backup-test Completed 121 14 2017-07-26 11:48:24 -0400 EDT <none>
|
|
backup-test-2-20170726180514 backup-test-2 Completed 0 0 2017-07-26 13:31:21 -0400 EDT <none>
|
|
backup-test-2-20170726180515 backup-test-2 Completed 0 1 2017-07-26 13:32:59 -0400 EDT <none>
|
|
```
|
|
|
|
To delve into the warnings and errors into more detail, you can use the `-o` option:
|
|
```
|
|
kubectl restore get backup-test-20170726180512 -o yaml
|
|
```
|
|
The output YAML has a `status` field which may look like the following:
|
|
```
|
|
status:
|
|
errors:
|
|
ark: null
|
|
cluster: null
|
|
namespaces: null
|
|
phase: Completed
|
|
validationErrors: null
|
|
warnings:
|
|
ark: null
|
|
cluster: null
|
|
namespaces:
|
|
cm1:
|
|
- secrets "default-token-t0slk" already exists
|
|
```
|
|
|
|
## Structure
|
|
The `status` field in a Restore's YAML has subfields for `errors` and `warnings`. `errors` appear for incomplete or partial restores. `warnings` appear for non-blocking issues (e.g. the restore looks "normal" and all resources referenced in the backup exist in some form, although some of them may have been pre-existing).
|
|
|
|
Both `errors` and `warnings` are structured in the same way:
|
|
|
|
* `ark`: A list of system-related issues encountered by the Ark server (e.g. couldn't read directory).
|
|
|
|
* `cluster`: A list of issues related to the restore of cluster-scoped resources.
|
|
|
|
* `namespaces`: A map of namespaces to the list of issues related to the restore of their respective resources.
