## 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",
|
||||||
|

|
||||||
|
"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
|
||||||
|
```
|
||||||
