SaltStack is used to deploy Kubernetes on top of Ubuntu virtual machines. OpenVpn provides network connectivity. For kubelet authentication, we use basic authentication (username and password). The scripts use the legacy Azure Service Management APIs. We have set up a nightly test job in our Jenkins server for federated testing to run the e2e test suite on Azure. With the cloud provider scripts in this commit, 14 e2e test cases pass in this environment. We plan to implement additional Azure functionality to support more test cases. --- cluster/azure-legacy/config-default.sh | 12 +-- .../templates/create-kubeconfig.sh | 77 ++++++++++++++++ cluster/azure-legacy/templates/salt-master.sh | 26 +++++- cluster/azure-legacy/templates/salt-minion.sh | 20 ++++- cluster/azure-legacy/util.sh | 58 +++++++++++- cluster/get-kube.sh | 2 +- cluster/saltbase/README.md | 2 +- cluster/saltbase/salt/docker/init.sls | 88 +++++++++++++++++++ cluster/saltbase/salt/generate-cert/init.sls | 2 +- .../kube-apiserver/kube-apiserver.manifest | 2 +- .../kube-controller-manager.manifest | 4 +- .../kube-master-addons/kube-master-addons.sh | 6 +- .../kube-node-unpacker/kube-node-unpacker.sh | 2 +- cluster/saltbase/salt/kube-proxy/default | 35 -------- .../salt/kube-proxy/kube-proxy.manifest | 2 +- cluster/saltbase/salt/kubelet/default | 6 +- cluster/saltbase/salt/nginx/init.sls | 64 ++++++++++++++ cluster/saltbase/salt/nginx/kubernetes-site | 66 ++++++++++++++ cluster/saltbase/salt/nginx/nginx.conf | 61 +++++++++++++ cluster/saltbase/salt/nginx/nginx.json | 60 +++++++++++++ cluster/saltbase/salt/openvpn/init.sls | 6 +- cluster/saltbase/salt/top.sls | 7 +- 22 files changed, 542 insertions(+), 66 deletions(-) create mode 100644 cluster/azure-legacy/templates/create-kubeconfig.sh delete mode 100644 cluster/saltbase/salt/kube-proxy/default create mode 100644 cluster/saltbase/salt/nginx/init.sls create mode 100644 cluster/saltbase/salt/nginx/kubernetes-site create mode 100644 cluster/saltbase/salt/nginx/nginx.conf create mode 100644 cluster/saltbase/salt/nginx/nginx.json diff --git a/cluster/azure-legacy/config-default.sh b/cluster/azure-legacy/config-default.sh index aa86c0c6790..988b636ff53 100644 --- a/cluster/azure-legacy/config-default.sh +++ b/cluster/azure-legacy/config-default.sh @@ -18,15 +18,17 @@ INSTANCE_PREFIX=kubernetes AZ_LOCATION='West US' TAG=testing AZ_CS_PREFIX=kube -AZ_VNET=MyVnet -AZ_SUBNET=Subnet-1 +AZ_VNET=${AZ_VNET:-MyVnet} +AZ_SUBNET=${AZ_SUBNET:-Subnet-1} AZ_IMAGE=b39f27a8b8c64d52b05eac6a62ebad85__Ubuntu-14_04_1-LTS-amd64-server-20140927-en-us-30GB -AZ_CS="" # is set in azure/util.sh verify-prereqs +AZ_CS="" # is set in azure-legacy/util.sh verify-prereqs AZ_SSH_KEY=$HOME/.ssh/azure_rsa AZ_SSH_CERT=$HOME/.ssh/azure.pem -NUM_MINIONS=4 +NUM_MINIONS=${NUM_MINIONS:-4} +MASTER_SIZE='Medium' +MINION_SIZE='Medium' MASTER_NAME="${INSTANCE_PREFIX}-master" MASTER_TAG="${INSTANCE_PREFIX}-master" @@ -35,7 +37,7 @@ MINION_NAMES=($(eval echo ${INSTANCE_PREFIX}-minion-{1..${NUM_MINIONS}})) MINION_IP_RANGES=($(eval echo "10.244.{1..${NUM_MINIONS}}.0/24")) MINION_SCOPES="" -SERVICE_CLUSTER_IP_RANGE="10.250.0.0/16" # formerly PORTAL_NET +SERVICE_CLUSTER_IP_RANGE="10.244.244.0/16" # formerly PORTAL_NET # Optional: Install node logging ENABLE_NODE_LOGGING=false diff --git a/cluster/azure-legacy/templates/create-kubeconfig.sh b/cluster/azure-legacy/templates/create-kubeconfig.sh new file mode 100644 index 00000000000..dec14472fa9 --- /dev/null +++ b/cluster/azure-legacy/templates/create-kubeconfig.sh @@ -0,0 +1,77 @@ +#!/bin/bash + +# Copyright 2014 The Kubernetes Authors All rights reserved. +# +# Licensed under the Apache License, Version 2.0 (the "License");
