-# Overview
-
-This is a [Juju] layer intended to ease the development of charms that need
-to execute commands over SSH, such as proxy charms.
-
-# What is a proxy charm?
-
-A proxy charm is a limited type of charm that does not interact with software running on the same host, such as controlling and configuring a remote device (a static VM image, a router/switch, etc.). It cannot take advantage of some of Juju's key features, such as [scaling], [relations], and [leadership].
-
-Proxy charms are primarily a stop-gap, intended to prototype quickly, with the end goal being to develop it into a full-featured charm, which installs and executes code on the same machine as the charm is running.
-
-# Integration
-
-After you've [created your charm], open `interfaces.yaml` and add
-`layer:sshproxy` to the includes stanza, as shown below:
-```
-includes: ['layer:basic', 'layer:sshproxy']
-```
-
-## Reactive states
-
-This layer will set the following states:
-
-- `sshproxy.configured` This state is set when SSH credentials have been supplied to the charm.
-
-
-## Example
-In `reactive/mycharm.py`, you can add logic to execute commands over SSH. This
-example is run via a `start` action, and starts a service running on a remote
-host.
-```
-...
-import charms.sshproxy
-
-
-@when('sshproxy.configured')
-@when('actions.start')
-def start():
- """ Execute's the command, via the start action` using the
- configured SSH credentials
- """
- sshproxy.ssh("service myservice start")
-
-```
-
-## Actions
-This layer includes a built-in `run` action useful for debugging or running arbitrary commands:
-
-```
-$ juju run-action mycharm/0 run command=hostname
-Action queued with id: 014b72f3-bc02-4ecb-8d38-72bce03bbb63
-
-$ juju show-action-output 014b72f3-bc02-4ecb-8d38-72bce03bbb63
-results:
- output: juju-66a5f3-11
-status: completed
-timing:
- completed: 2016-10-27 19:53:49 +0000 UTC
- enqueued: 2016-10-27 19:53:44 +0000 UTC
- started: 2016-10-27 19:53:48 +0000 UTC
-
-```
-## Known Limitations and Issues
-
-### Security issues
-
-- Password and key-based authentications are supported, with the caveat that
-both (password and private key) are stored plaintext within the Juju controller.
-
-# Configuration and Usage
-
-This layer adds the following configuration options:
-- ssh-hostname
-- ssh-username
-- ssh-password
-- ssh-private-key
-
-Once [configure] those values at any time. Once they are set, the `sshproxy.configured` state flag will be toggled:
-
-```
-juju deploy mycharm ssh-hostname=10.10.10.10 ssh-username=ubuntu ssh-password=yourpassword
-```
-or
-```
-juju deploy mycharm ssh-hostname=10.10.10.10 ssh-username=ubuntu ssh-private-key="`cat ~/.ssh/id_rsa`"
-```

-## Overview
-
-This charm layer is intended for use by vendors who wish to integrate with
-OSM. The current release of OSM only supports a lightweight version of Juju
-charms, which we will refer to as "proxy charms". Consider the diagram below:
-
-```
-+---------------------+ +---------------------+
-| <----+ |
-| Resource | | Service |
-| Orchestrator (RO) +----> Orchestrator (SO) |
-| | | |
-+------------------+--+ +-------+----^--------+
- | | |
- | | |
- | | |
- +-----v-----+ +-v----+--+
- | <-------+ |
- | Virtual | | Proxy |
- | Machine | | Charm |
- | +-------> |
- +-----------+ +---------+
-```
-
-The Virtual Machine (VM) is created by the Resource Orchestrator (RO), at the
-request of the Service Orchestrator (SO). Once the VM has been created, a
-"proxy charm" is deployed in order to facilitate operations between the SO and
-your service running within the VM.
-
-As such, a proxy charm will expose a number of "actions" that are run via the
-SO. By default, the following actions are exposed:
-
-```bash
-actions
-├── reboot
-├── restart
-├── run
-├── start
-└── stop
-```
-
-Some actions, such as `run` and `reboot`, do not require any additional configuration. `start`, `stop` and `restart`, however, will require you to
-implement the command(s) required to interact with your service.
-
-## Usage
-
-Create the framework for your proxy charm:
-
-```bash
-$ charm create pingpong
-$ cd pingpong
-```
-
-Modify `layer.yaml` to the following:
-```yaml
-includes:
- - layer:basic
- - layer:vnfproxy
-```
-
-The `metadata.yaml` describes your service. It should look similar to the following:
-
-```yaml
-name: vnfproxy
-summary: A layer for developing OSM "proxy" charms.
-maintainer: Adam Israel <adam.israel@canonical.com>
-description: |
- VNF "proxy" charms are a lightweight version of a charm that, rather than
- installing software on the same machine, execute commands over an ssh channel.
-series:
- - trusty
- - xenial
-tags:
- - osm
- - vnf
-subordinate: false
-```
-
-Implement the default action(s) you wish to support by adding the following code to reactive/pingpong.py and fill in the cmd to be run:
-
-```python
-@when('actions.start')
-def start():
- err = ''
- try:
- cmd = ""
- result, err = charms.sshproxy._run(cmd)
- except:
- action_fail('command failed:' + err)
- else:
- action_set({'outout': result})
- finally:
- remove_flag('actions.start')
-
-
-@when('actions.stop')
-def stop():
- err = ''
- try:
- # Enter the command to stop your service(s)
- cmd = "service myname stop"
- result, err = charms.sshproxy._run(cmd)
- except:
- action_fail('command failed:' + err)
- else:
- action_set({'outout': result})
- finally:
- remove_flag('actions.stop')
-
-
-@when('actions.restart')
-def restart():
- err = ''
- try:
- # Enter the command to restart your service(s)
- cmd = "service myname restart"
- result, err = charms.sshproxy._run(cmd)
- except:
- action_fail('command failed:' + err)
- else:
- action_set({'outout': result})
- finally:
- remove_flag('actions.restart')
-```
-
-Rename `README.ex` to `README.md` and describe your application and its usage.
-
--- fix this. there are cases where the config is useful -- Delete `config.yaml`, since the charm's configuration will be driven by the SO.
-
-Create the `actions.yaml` file; this will describe the additional operations you would like to perform on or against your service.
-
-```yaml
-set-server:
- description: "Set the target IP address and port"
- params:
- server-ip:
- description: "IP on which the target service is listening."
- type: string
- default: ""
- server-port:
- description: "Port on which the target service is listening."
- type: integer
- default: 5555
- required:
- - server-ip
-set-rate:
- description: "Set the rate of packet generation."
- params:
- rate:
- description: "Packet rate."
- type: integer
- default: 5
-get-stats:
- description: "Get the stats."
-get-state:
- description: "Get the admin state of the target service."
-get-rate:
- description: "Get the rate set on the target service."
-get-server:
- description: "Get the target server and IP set"
-```
-
-
-Once you've implemented your actions, you need to compile the various charm layers:
-```bash
-$ charm build
-
-```

- installing software on the same machine, execute commands over an ssh channel.
