# Ops Toolbelt

[![REUSE status](https://api.reuse.software/badge/github.com/gardener/ops-toolbelt)](https://api.reuse.software/info/github.com/gardener/ops-toolbelt)

## What is the ops-toolbelt?

The `ops-toolbelt` aims to be a standard container image with pre-installed useful tools for troubleshooting issues on gardener landscapes for human operators.

The pods created with this image can be both general pods and node-bound pods (behaving as if being on the node directly).
Starting a pod with the `ops-toolbelt` image requires a running `Kubelet`, a healthy control plane, a working VPN connection, and sufficient capacity on the node.

## Usage

### Running a container locally

The simplest way of using the `ops-toolbelt` is to just run the following command:

```bash
$ docker run -it europe-docker.pkg.dev/gardener-project/releases/gardener/ops-toolbelt:latest

__ _  __ _ _ __ __| | ___ _ __   ___ _ __   ___| |__   ___| | |
 / _` |/ _` | '__/ _` |/ _ \ '_ \ / _ \ '__| / __| '_ \ / _ \ | |
| (_| | (_| | | | (_| |  __/ | | |  __/ |    \__ \ | | |  __/ | |
 \__, |\__,_|_|  \__,_|\___|_| |_|\___|_|    |___/_| |_|\___|_|_|
 |___/

Run ghelp to get information about installed tools and packages
```

You can then add personal configurations to your `ops-toolbelt` container for tools like `kubectl`, `gcloud` and so on.

### Running ops-toolbelt as a privileged pod on a node

Get the names of the nodes on your cluster and then run `hacks/ops-pod` with the node you want to start the pod on:

```bash
$ kubectl get nodes                                                    
NAME                                          STATUS   ROLES    AGE     VERSION
node1                                         Ready    <none>   3h23m   v1.30.4
node2                                         Ready    <none>   24h     v1.30.4
node3                                         Ready    <none>   11h     v1.30.4
node4                                         Ready    <none>   7h44m   v1.30.4

$ ./hacks/ops-pod node1 -n kube-system

                     _                            _          _ _

 \__, |\__,_|_|  \__,_|\___|_| |_|\___|_|    |___/_| |_|\___|_|_|

Run ghelp to get information about installed tools and packages

root at ops-pod in /
$
```

Use `./hacks/ops-pod --help` to check what other options are available

## Building ops-toolbelt images

Dockerfiles for the images are generated from files in the `dockerfile-configs` directory.

To generate the Dockerfile for the ops-toolbelt, run:

```bash
$ make build
```

The generated Dockerfile is created under the `generated_dockerfiles` directory.  
To build the image, use:

```bash
$ make build-image
```

to build the corresponding image.

You can run the image with:

```bash
docker run -ti --rm ops-toobelt:latest

## Known issues

1. Currently, there's a known issue when using `/bin/sh`. We implemented a color scheme and also added some helper function to display in `/bin/bash` terminal which doesn't work in `/bin/sh`. As workaround when you want to use some script which by default needs to utilize `/bin/sh` please use `/bin/bash` instead if possible: (take `chroot` for example).

```bash
$ chroot /some_dir /bin/bash
```
