## Examples ## Usage Examples
*If you are reading this it means that you are testing ucloud before its general public release. So, this document assume that you are both maintainer (person who install/manage ucloud installation) and enduser of ucloud.*
### Create Image From File
The first step after installation of ucloud is to create a base image on which VMs would base themself. To do this, perform the following steps
1. Upload a **.qcow2** OS image under /var/www/$username where $username would be your username.
2. Wait for few seconds so that your image/file get tracked by ucloud-file-scanner
3. Now, list all of your files. You can do this by executing `python ucloud.py user files --name $username --realm $realm --seed $seed`. A sample output is given below
```json
{
"message": [
{
"filename": "alpine.qcow2",
"uuid": "aa323e6a-2479-4554-b2b2-7a2eb1b9952f"
},
]
}
```
4. As, you can see we uploaded alpine.qcow2 image. You can upload any image as far as it is in qcow2 format.
5. Now, execute the following command to ask ucloud to create base image and make it publicly available for other as well.
```shell
python ucloud.py image create-from-file --name alpineLinux --uuid aa323e6a-2479-4554-b2b2-7a2eb1b9952f ----image_store_name images
```
6. If you list public images at this point by executing the command `python ucloud.py image list --public` you would get something like this
```json
{
"aa323e6a-2479-4554-b2b2-7a2eb1b9952f": {
"filename": "alpine.qcow2",
"name": "alpine",
"owner": "ahmedbilal-admin",
"status": "TO_BE_CREATED",
"store_name": "images",
"visibility": "public"
}
}
```
Note the **TO_BE_CREATED** status. It means that it is not yet to be available to use.
7. If you wait for few seconds and run the command again you would see something like this if everything goes correctly.
```json
{
"aa323e6a-2479-4554-b2b2-7a2eb1b9952f": {
"filename": "alpine.qcow2",
"name": "alpine",
"owner": "ahmedbilal-admin",
"status": "CREATED",
"store_name": "images",
"visibility": "public"
}
}
```
It means that the image is available for consumption now.
### List Public Base Images (OS Images)
Execute the following command to get list of all publicly available base images. Then, you can use these images to create a VM for yourself.
```bash
python ucloud.py image list --public
```
Sample output is as follows
```json
{
"aa323e6a-2479-4554-b2b2-7a2eb1b9952f": {
"filename": "alpine.qcow2",
"name": "alpine",
"owner": "ahmedbilal-admin",
"status": "CREATED",
"store_name": "images",
"visibility": "public"
}
}
```

### Start/Stop/Delete a VM
1. First you need to know the [UUID](https://en.wikipedia.org/wiki/Universally_unique_identifier) of a vm to start/stop/delete it
2. For that, you would need to list your vms. You can do this by executing the following command
```bash
python ucloud.py user vms --name $username --realm $realm --seed $seed
```
It will show list of your VMs and their details. Sample output is as follow
```json
{
"message": [
{
"hostname": "/v1/host/cc7f5d199c2a419eb103c2bf10d9ca79",
"specs": {
"cpu": 2,
"hdd": 10000000000,
"ram": 2000000000
},
"status": "STOPPED",
"vm_uuid": "dbe8810e7a224aaea93929c4cee0ccea"
}
]
}
```
3. Now, we got VM's UUID. So, we can start/stop/delete it. Execute, the following command to start/stop/delete the vm.
**Note:** Replace the $action with either **start**, **stop** or **delete**.
```bash
python ucloud.py vm $action --uuid dbe8810e7a224aaea93929c4cee0ccea --name $username --realm $realm --seed $seed
```
It would show something like the following
```json
{
"message": "VM $action Queued"
}
```
### Get Status of a VM
Run the following command to get detailed status of a VM
```bash
python ucloud.py vm status --uuid dbe8810e7a224aaea93929c4cee0ccea
```
Sample output is as follow.
```json
{
"owner": "ahmedbilal-admin",
"specs": {
"cpu": 2,
"ram": 2000000000,
"hdd": 10000000000

}
```
### List VMs
Run the following command
```bash
python ucloud.py user vms --name $username --realm $realm --seed $seed
```
It would show your VMs. Sample output is as follow.
```json
