This PS seeks to reduce the load exerted on the node in the single node gate test - as a the single node gate is currently broken due to resource starvation on the nodes. Change-Id: I34db5108b4abb48bb452eed73067644cc03270c0
Openstack-Helm Gate Scripts
===========================
These scripts are used in the OpenStack-Helm Gates and can also be run
locally to aid development and for demonstration purposes. Please note
that they assume full control of a machine, and may be destructive in
nature, so should only be run on a dedicated host.
Supported Platforms
~~~~~~~~~~~~~~~~~~~
Currently supported host platforms are:
* Ubuntu 16.04
* CentOS 7
* Fedora 25
Usage (Single Node)
-------------------
The Gate scripts use the ``setup_gate.sh`` as an entrypoint and are
controlled by environment variables, an example of use to run the basic
integration test is below:
.. code:: bash
export INTEGRATION=aio
export INTEGRATION_TYPE=basic
export PVC_BACKEND=ceph
./tools/gate/setup_gate.sh
Usage (Multi Node)
------------------
To use for a multinode deployment you simply need to set a few extra environment
variables:
.. code:: bash
export INTEGRATION=multi
export INTEGRATION_TYPE=basic
export PVC_BACKEND=ceph
#IP of primary node:
export PRIMARY_NODE_IP=1.2.3.4
#IP's of subnodes:
export SUB_NODE_IPS="1.2.3.5 1.2.3.6 1.2.3.7"
#Location of SSH private key to use with subnodes:
export SSH_PRIVATE_KEY=/etc/nodepool/id_rsa
./tools/gate/setup_gate.sh
Options
-------
You can also export some additional environment variables prior to running the
``./tools/gate/setup_gate.sh`` that tweak aspects of the deployment.
Rather than ceph, you may use a nfs based backend. This option is especially
useful on old or low spec machines, though is not currently supported with
Linux Kernels >=4.10:
.. code:: bash
export PVC_BACKEND=nfs
It is also possible to customise the CNI used in the deployment:
.. code:: bash
export KUBE_CNI=calico # or "canal" "weave" "flannel"
export CNI_POD_CIDR=192.168.0.0/16
