# pv_inspect
Small utility to "shell into" a Kubernetes volume and mount it locally if desired.
This allows easily inspecting or accessing volumes, even when they are not already mounted.
This works by automatically:
- Creating a new pod with the volume attached.
- Opening a shell into the pod.
- Optionally mounting the volume locally via SSHFS, after port forwarding on an OpenSSH server running on the pod.
- Deleting the pod when the tool is exited.
## Installation
See the packages on the [releases page](https://github.com/cpg314/pv_inspect/releases).
Alternatively, compile with cargo:
```console
$ cargo install --git https://github.com/cpg314/pv_inspect
```
## Usage
```
Mount a PVC on a new pod, shell into it, and mount it (via SSHFS) if desired
Usage: pv_inspect [OPTIONS] [NAME]
Arguments:
[NAME] Name of the PVC to inspect. If not provided, a list will be shown.
Options:
-n, --namespace [default: default]
-m, --mountpoint
--rw Mount the volume in read/write mode rather than read only
--nowait Do not wait until the pod has been deleted
--cleanup Cleanup stale pv_inspect pods and exit
--cleanup-min Age in minutes to cleanup pods [default: 240]
-h, --help Print help
-V, --version Print version
```
For example:
```console
$ pv_inspect -n mynamespace --rw mypvc
$ # Mount locally
$ pv_inspect -n mynamespace --rw -m ~/mounts/volume mypvc
```
### As a `k9s` plugin
If you use the [k9s Kubernetes TUI](https://k9scli.io/), you can install `pv_inspect` as a plugin by editing your plugins configuration (see the output of `k9s info`) as follows:
```yaml
plugins:
pv_inspect:
shortCut: p
description: pv_inspect
scopes:
- pvc
command: pv_inspect
args:
- -n
- $NAMESPACE
- $NAME
```
When viewing `PersistentVolumeClaims`, the `p` key (or any other you might choose) will launch `pv_inspect`:
## Cleanup
The `--cleanup` command allows delete `pv_inspect` dangling pods, due to the client aborting before deletion. It can also be executed on the cluster as a cronjob, see [`cleanup_job.yaml`](cleanup_job.yaml).
## TODO
- `rsync`-style subcommand.
