    Travis CI test matrix

    GCE instances

    Here is the test matrix for the CI gates:

    Network plugin OS type GCE region Nodes layout
    canal debian-8-kubespray asia-east1-a ha-scale
    calico debian-8-kubespray europe-west1-c default
    flannel centos-7 asia-northeast1-c default
    calico centos-7 us-central1-b ha
    weave rhel-7 us-east1-c default
    canal coreos-stable us-west1-b ha-scale
    canal rhel-7 asia-northeast1-b separate
    weave ubuntu-1604-xenial europe-west1-d separate
    calico coreos-stable us-central1-f separate

    Node Layouts

    There are four node layout types: default, separate, ha, and scale.

    default is a non-HA two nodes setup with one separate kube-node and the etcd group merged with the kube-master.

    separate layout is when there is only node of each type, which includes a kube-master, kube-node, and etcd cluster member.

    ha layout consists of two etcd nodes, two masters and a single worker node, with role intersection.

    scale layout can be combined with above layouts. It includes 200 fake hosts in the Ansible inventory. This helps test TLS certificate generation at scale to prevent regressions and profile certain long-running tasks. These nodes are never actually deployed, but certificates are generated for them.

    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.

    The "Stage" means a build step of the build pipeline. The steps are ordered as part1->part2->special.
