Travis CI test matrix
|
||||
=====================
|
||||
|
||||
GCE instances
|
||||
-------------
|
||||
|
||||
Here is the test matrix for the Travis CI gates:
|
||||
|
||||
| Network plugin| OS type| GCE region| Nodes layout|
|
||||
|-------------------------|-------------------------|-------------------------|-------------------------|
|
||||
| flannel| debian-8-kubespray| europe-west1-b| default|
|
||||
| calico| debian-8-kubespray| us-central1-c| default|
|
||||
| flannel| centos-7-sudo| asia-east1-c| default|
|
||||
| calico| centos-7-sudo| europe-west1-b| default|
|
||||
| weave| centos-7-sudo| us-central1-c| default|
|
||||
| calico| rhel-7-sudo| asia-east1-c| default|
|
||||
| weave| rhel-7-sudo| europe-west1-b| default|
|
||||
| canal| ubuntu-1604-xenial| us-central1-c| default|
|
||||
| weave| ubuntu-1604-xenial| asia-east1-c| default|
|
||||
| weave| coreos-stable| europe-west1-b| default|
|
||||
| canal| coreos-stable| us-east1-d| default|
|
||||
| canal| rhel-7-sudo| europe-west1-b| separate|
|
||||
| calico| ubuntu-1604-xenial| us-central1-a| separate|
|
||||
| weave| debian-8-kubespray| us-east1-d| separate|
|
||||
| calico| coreos-stable| asia-east1-c| separate|
|
||||
|
||||
Where the nodes layout `default` is that is given in the example inventory file.
|
||||
And the `separate` layout is when there is only node of each type, which is a kube master,
|
||||
compute and etcd cluster member.
|
||||
|
||||
Note, the canal network plugin deploys flannel as well plus calico policy controller.
|
||||
|
||||
Hint: the command
|
||||
```
|
||||
bash scripts/gen_matrix.sh
|
||||
```
|
||||
will (hopefully) generate the CI test cases from the current ``.travis.yml``.
