Note: all scripts in tools/deployment/aiab directory have been
moved into this repository as is (except a few changes to make
them work), they require a heavy refactoring that will be done
in separate patch-sets.
* Add a virtual single node manifests that are based on a sloop type.
* Use NFS provisioner instead of Ceph.
* Update tools/openstack to be non-seaworthy specific, use a default
region name and auth url.
* Make type/sloop/config/common-software-config.yaml to be site specific,
to allow to configure custom region_name.
* Remove max-pods-per-cpu parameter for kubelet, treasuremap needs
to support a diverse set of environments, without constraints
on the number of available cores. Max pods configuration parameter
is still present and helps to mitigate problems when kubernetes
unexpectedly starts a large number of pods.
Override default "metadata_proxy_shared_secret" parameter.
This secret is used by Neutron to sign instance-id headers
to prevent spoofing when proxying metadata requests.
Sloop type/site is a minimalistic approach to Airship with reduced
requirements towards hardware and external dependencies while keeping
all the functional features.
Major differences compared to reference site airship-seaworthy
- Two bare-metal server setup with 1 control, and 1 compute.
Most components are scaled to a single replica and doesn't carry
any HA as there is only a single control plane host.
- No requirements for DNS/certificates.
HTTP and internal cluster DNS is used.
- Ceph set to use the single (root) disk. This generally
provides minimalistic no-touch ceph deployment.
No replication of ceph data (single copy).
- Simplified networking (no bonding).
Two network interfaces are used by default (flat PXE, and DATA network
with VLANs for OAM, Calico, Storage, and OpenStack Overlay)
- Generic hostnames used (airsloop-control-1, airsloop-compute-1) that
simplifies generation of k8s certificates
- Usage of standard Ubuntu 16.04 GA kernel (as oppose to HWE)
