克隆现有机器

为了在多个节点上构建集群，您可以将已配置的实例克隆到新的节点。您无需重新安装所有内容！

首先创建正在运行实例的镜像并将其上传到 Google Cloud Storage

# Create an image of your current instance
sudo /usr/bin/gcimagebundle -d /dev/sda -o /tmp/

# An image has been created in `/tmp` directory:
ls /tmp
e4686d7f5bf904a924ae0cfeb58d0827c6d5b966.image.tar.gz

# Upload your image to Google Cloud Storage:
# Create a bucket to hold your image, let's say `esimage`:
gsutil mb gs://esimage

# Copy your image to this bucket:
gsutil cp /tmp/e4686d7f5bf904a924ae0cfeb58d0827c6d5b966.image.tar.gz gs://esimage

# Then add your image to images collection:
gcloud compute images create elasticsearch-2-0-0 --source-uri gs://esimage/e4686d7f5bf904a924ae0cfeb58d0827c6d5b966.image.tar.gz

# If the previous command did not work for you, logout from your instance
# and launch the same command from your local machine.

启动新实例

编辑

现在您有了镜像，您可以根据需要创建任意数量的实例。

# Just change node name (here myesnode2)
gcloud compute instances create myesnode2 --image elasticsearch-2-0-0 --zone europe-west1-a

# If you want to provide all details directly, you can use:
gcloud compute instances create myesnode2 --image=elasticsearch-2-0-0 \
       --zone europe-west1-a --machine-type f1-micro --scopes=compute-rw

移除实例（也称为关闭实例）

编辑

您可以使用 Google Cloud Console 或 CLI 来管理您的实例。

# Stopping and removing instances
gcloud compute instances delete myesnode1 myesnode2 \
       --zone=europe-west1-a

# Consider removing disk as well if you don't need them anymore
gcloud compute disks delete boot-myesnode1 boot-myesnode2  \
       --zone=europe-west1-a
