Update Gophercloud dependencies and also bring in the 'utils' package. This provides support for configuring access to OpenStack clouds as detailed in the [official documentation](https://docs.openstack.org/os-client-config/latest/user/configuration.html). By relying on this package we can simplify the code required to interact with OpenStack's APIs. Support is also provided upstream for self-signed and insecure SSL configurations. Tested with a public cloud running OpenStack 'Rocky', the latest release. Signed-off-by: Nick Jones <nick@dischord.org>

# LinuxKit with OpenStack
|
|
|
|
LinuxKit interacts with OpenStack through its native APIs, providing basic support for pushing images and launching virtual instances.
|
|
|
|
Supported (tested) versions of the relevant OpenStack APIs are:
|
|
|
|
- Keystone v3
|
|
- Glance v2
|
|
- Nova v2
|
|
- Neutron v2
|
|
|
|
## Authentication
|
|
|
|
LinuxKit's support for OpenStack includes configuring access to your cloud as detailed in the official [os-client-config](https://docs.openstack.org/os-client-config/latest/user/configuration.html) documentation.
|
|
|
|
## Push
|
|
|
|
### Image types supported:
|
|
- **ami** (Amazon Machine image)
|
|
- **vhd** (Hyper-V)
|
|
- **vhdx** (Hyper-V)
|
|
- **vmdk** (VMware Disk)
|
|
- **raw** (Raw disk image)
|
|
- **qcow2** (Qemu disk image)
|
|
- **iso** (ISO9660 compatible CD-ROM image)
|
|
|
|
A compatible image needs to have the correct extension (must match one from above) in order to be supported by the `linuxkit push openstack` command. The `openstack` backend will use the filename extension to determine the image type, and use the filename as a label for the new image.
|
|
|
|
Images generated with Moby can be uploaded into OpenStack's image service with `linuxkit push openstack`, plus a few options. For example:
|
|
|
|
```shell
|
|
./linuxkit push openstack \
|
|
-img-name=LinuxKitTest
|
|
./linuxkit.iso
|
|
```
|
|
|
|
## Run
|
|
|
|
Virtual machines can be launched using `linuxkit run openstack`. As an example:
|
|
|
|
```shell
|
|
linuxkit run openstack \
|
|
-flavor=hotdog
|
|
-keyname=deadline_ed25519 \
|
|
-sec-groups=allow_ssh,nginx \
|
|
-network c5d02c5f-c625-4539-8aed-1dab3aa85a0a \
|
|
LinuxKitTest
|
|
```
|
|
|
|
This will create a new instance with the same name as the image, and if successful will return the newly-created instance's UUID. You can then check the boot logs as follows, e.g:
|
|
|
|
```shell
|
|
$ openstack console log show 7cdd4d53-78b3-47c7-9a77-ba8a3f60548d
