Installation tarballs
Installation
Base tarball
Given kubernetes.tar.gz:
$ tar xzf kubernetes.tar.gz
then script runs:
download_kube_binariescreate_cluster
download_kube_binaries()
Invokes get-kube-binaries.sh:
# Use the script from inside the Kubernetes tarball to fetch the client and
# server binaries (if not included in kubernetes.tar.gz).
function download_kube_binaries {
(
cd kubernetes
if [[ -x ./cluster/get-kube-binaries.sh ]]; then
# Make sure to use the same download URL in get-kube-binaries.sh
KUBERNETES_RELEASE_URL="${KUBERNETES_RELEASE_URL}" \
./cluster/get-kube-binaries.sh
fi
)
}
create_cluster()
Invokes kube-up.sh:
function create_cluster {
if [[ -n "${KUBERNETES_SKIP_CREATE_CLUSTER-}" ]]; then
exit 0
fi
echo "Creating a kubernetes on ${KUBERNETES_PROVIDER:-gce}..."
(
cd kubernetes
./cluster/kube-up.sh
echo "Kubernetes binaries at ${PWD}/cluster/"
if [[ ":$PATH:" != *":${PWD}/cluster:"* ]]; then
echo "You may want to add this directory to your PATH in \$HOME/.profile"
fi
echo "Installation successful!"
)
}
cluster/get-kube-binaries.sh
KUBE_ROOT=$(cd $(dirname "${BASH_SOURCE}")/.. && pwd)
KUBE_VERSION=$(cat "${KUBE_ROOT}/version")
CLIENT_PLATFORM="linux"
CLIENT_ARCH="amd64"
SERVER_TAR="kubernetes-server-${SERVER_PLATFORM}-${SERVER_ARCH}.tar.gz"
CLIENT_TAR="kubernetes-client-${CLIENT_PLATFORM}-${CLIENT_ARCH}.tar.gz"
Result:
Will download kubernetes-server-linux-amd64.tar.gz from https://dl.k8s.io/v1.10.0 Will download and extract kubernetes-client-linux-amd64.tar.gz from https://dl.k8s.io/v1.10.0
