LinuxKit with OpenStack
LinuxKit interacts with OpenStack through its native APIs and requires access to both an OpenStack Keystone server for authentication and a OpenStack Glance server in order to host the LinuxKit images.
Supported (Tested) Versions:
- OpenStack Ocata Release
- Keystone v3 API
- Glance v2 API
##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/supported 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.
The openstack backend also supports OpenStack projects to provide
multi-tenancy support when uploading images.
Usage
The openstack backend uses the password authentication method in order to
retrieve a token that can be used to interact with the various components of
OpenStack. The URLs for the Keystone/Glance server components need to have
the ports detailed as below.
./linuxkit push openstack \
-keystoneAddr=http://keystone.com:5000 \
-username=admin \
-password=XXXXXXXXXXX \
-project=linuxkit \
-glanceAddr=http://glance.com:9292 \
./linuxkit.iso
Execution Flow
- Log in to OpenStack (Keystone)
- Retrieve the OpenStack Key from the response header
- Create a "queued" image on the glance server and return the new image ID
- Use the new image ID and upload the LinuxKit image under this new ID
