# Kubectl Openstack Plugin
[](https://travis-ci.org/sbueringer/kubectl-openstack-plugin)[](https://codecov.io/gh/sbueringer/kubectl-openstack-plugin)[](https://www.codefactor.io/repository/github/sbueringer/kubectl-openstack-plugin)[](https://goreportcard.com/report/github.com/sbueringer/kubectl-openstack-plugin)[](https://github.com/sbueringer/kubectl-openstack-plugin/releases)
based on [k8s.io/sample-cli-plugin](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/sample-cli-plugin)
# Installation
## Prerequisites
* Afaik kubectl plugins without plugin.yaml only work with kubectl >=1.12
## Installation via go get
Just execute the following and make sure `$GOPATH/bin` is in your `$PATH`:
````
GO111MODULE=on go get github.com/sbueringer/kubectl-openstack-plugin/cmd/[email protected]
````
Note: this currently only works without GO111MODULE=on because a replace directive for gophercloud is used. (see also: https://github.com/golang/go/issues/30354)
## Installation via download
Download the binary from [Releases](https://github.com/sbueringer/kubectl-openstack-plugin/releases) and place it in a directory in your `PATH`.
# Configuration
To access OpenStack via this plugin the OpenStack credentials must be configured either via env variables or via [clouds.yaml](https://docs.openstack.org/python-openstackclient/pike/configuration/index.html) config file.
## Configuration via Environment Variables
The plugin can be configured by setting the following env variables:
* `OS_USERNAME`
* `OS_PASSWORD`
* `OS_PROJECT_NAME` or `OS_TENANT_NAME`
* `OS_AUTH_URL`
## Configuration via config file
The location of the config file must be configured via `OPENSTACK_CONFIG_FILE` env var. An example `clouds.yaml`:
````
clouds:
i01p015:
auth:
auth_url: http://192.168.122.10:35357/
project_name: i01p015
username: demo
password: password
````
*Note*: The cloud/project_name is automatically discovered from the current kube context. E.g. a kube context named `i01p015-cluster-admin` leads to a cloud/project_name of `i01p015`.
*Note*: The clouds.yaml file can be created from `.rc` files via the `import-config` sub command.
# Usage
The kubectl OpenStack plugin currently has three commands, which are shown here.
## kubectl openstack server
The `server` command combines information about Kubernetes Nodes with OpenStack Server.
````
$ kubectl openstack server
NODE_NAME STATUS KUBELET_VERSION KUBEPROXY_VERSION RUNTIME_VERSION SERVER_ID STATE CPU RAM IP

````
## kubectl openstack volumes
The `volumes` command combines information about Kubernetes Persistent Volumes & Nodes with OpenStack Volumes.
````
$ kubectl openstack volumes

# Roadmap
* enable output via go template like json path (from both openstack & kube object)
* unit tests
