Command-line API
The Coriolis Command-line API offers an interface over the REST API provided by
the Coriolis migration service.
Coriolis uses Keystone for identity management. Credentials and endpoints can
be provided via environment variables or command line parameters in the same
way supported by most OpenStack command line interface (CLI) tools, e.g.:
export OS_AUTH_URL=http://example.com:5000/v2.0
export OS_USERNAME=admin
export OS_PASSWORD=blahblah
export OS_TENANT_NAME=admin
Secrets
In order to migrate virtual workloads, Coriolis requires access to external
environments, e.g. VMware vSphere, AWS, Azure, etc.
Connection details including credentials can be stored in Barbican,
OpenStack’s project for secure storage and secrets management:
VMWARE_CONN_INFO='{"host": "example.com", "port": 443, "username":
"[email protected]", "password": "blahblah", "allow_untrusted": true}'
barbican secret store --payload "$VMWARE_CONN_INFO" \
--payload-content-type "text/plain"
The returned Secret href is the id of the secret to be referenced in order
to access its content.
Providers
A provider is a registered extension that supports a given cloud or
virtual environment, like OpenStack, Azure, AWS, VMware vSphere, etc.
There are two types of providers: origin and destination. For example, when
migrating a VM from VMware vSphere to OpenStack, wmware_vsphere is the
origin and openstack the destination.
Target environment
A target environment defines a set of provider specific parameters that can
override default options set by the Coriolis work processes. For example in the
case of the OpenStack’s provider, the following JSON formatted values allow to
specify a custom mapping between origin and Neutron networks, along with a
specific Nova flavor for the migrated instance and a custom worker image name:
TARGET_ENV='{"network_map": {"VM Network Local": "public", "VM Network":
"private"}, "flavor_name": "m1.small", "migr_image_name": "Nano"}'
Starting a migration
Various types of virtual workloads can be migrated, including instances,
templates, network configurations and storage.
The following command migrates a virtual machine named VM1 from VMware
vSphere to OpenStack:
coriolis migration create --origin-provider vmware_vsphere
--destination-provider openstack --origin-connection-secret $SECRET_REF
--instance VM1 --target-environment "$TARGET_ENV"
List all migrations
The following command retrieves a list of all migrations, including their
status:
coriolis migration list
Show migration details
Migrations can be fairly long running tasks. This command is very useful to
retrieve the current status and all progress updates:
coriolis migration show <migration_id>
Cancel a migration
A pending or running migration can be canceled anytime:
coriolis migration cancel <migration_id>
Delete a migation
Only migrations in pending or error state can be deleted. Running migrations
need to be first cancelled:
coriolis migration delete <migration_id>
Python API
The Python interface matches the underlying REST API, it’s used by the CLI and
can be employed in 3rd party projects:
>>> from coriolisclient import client
>>> c = client.Client(session=keystone_session)
>>> c.migrations.list()
[...]
>>> c.migrations.get(migration_id)
[...]
