Native ssh compression has existed for years, and the server is free to disregard the setting, so this should be safe. With things like the kube binaries I see about a 2x speed increase. ``` λ time scp kubes-bin.tar 9.30.182.251:/mnt/build/kubin kubes-bin.tar 100% 344MB 10.7MB/s 00:32 real 0m32.284s user 0m1.679s sys 0m1.263s λ time scp -C kubes-bin.tar 9.30.182.251:/mnt/build/kubin kubes-bin.tar 100% 344MB 22.9MB/s 00:15 real 0m14.810s user 0m12.858s sys 0m0.994s λ ls -lah kubes-bin.tar -rw-r--r-- 1 mhb staff 344M Jun 2 15:29 kubes-bin.tar λ tar -tf kubes-bin.tar kubectl master/ master/etcd master/etcdctl master/flanneld master/kube-apiserver master/kube-controller-manager master/kube-scheduler node/ node/flanneld node/kube-proxy node/kubelet ```
Cluster Configuration
Deprecation Notice: This directory has entered maintainence mode and will not be accepting new providers. Please submit new automation deployments to kube-deploy. Deployments in this directory will continue to be maintained and supported at their current level of support.
The scripts and data in this directory automate creation and configuration of a Kubernetes cluster, including networking, DNS, nodes, and master components.
See the getting-started guides for examples of how to use the scripts.
cloudprovider/config-default.sh contains a set of tweakable definitions/parameters for the cluster.
The heavy lifting of configuring the VMs is done by SaltStack.
