使用GCE（Google Container Engine）体验容器云服务 (1)
2015-09-09 wcdj
摘要：本文记录使用GCE（Google Container Engine）体验容器云服务的过程和方法。
（1）要申请一个Google账户。
（2）激活Google账单，即绑定支付信用卡，为使用Google的服务买单。激活过程中为了验证信用卡是否可用，需要支付1美元的费用。
激活支付地址：https://console.developers.google.com/billing?_ga=1.62759852.1080048005.1441690490
支付激活后，可以看到能够使用的一些服务，同时看到可以免费使用60天。
（3）激活Google API
激活后，可以使用如下两种服务：
- Google Container Engine API
- Google Compute Engine and associated APIs
创建一个gerry-test-proj工程：
然后点击建立，会自动跳转到当前创建好的工程中：
（4）安装gcloud
The Container Engine API uses the gcloud command line tool for clusteroperations and for managing credentials.
Install thegcloud tool.
安装完成后，可以看下gcloud的使用方法：
root@gerryyang:~# gcloud -h
Usage: gcloud [optional flags]
group may be auth | components | compute | config | container |
deployment-manager | dns | sql | topic
command may be docker | feedback | help | info | init | version
The *gcloud* CLI manages authentication, local configuration, developer
workflow, and interactions with the Google Cloud Platform APIs.
optional flags:
--account ACCOUNT Google Cloud Platform user account to use for
invocation.
--format FORMAT Format for printed output.
--help Display detailed help.
--log-http LOG_HTTP Logs all HTTP server requests and responses to stderr.
(true/false)
--project PROJECT_ID Google Cloud Platform project ID to use for this
invocation.
--quiet, -q Disable all interactive prompts.
--trace-token TRACE_TOKEN
Token used to route traces of service requests for
investigation of issues.
--user-output-enabled USER_OUTPUT_ENABLED
Control whether user intended output is printed to the
console. (true/false)
--verbosity VERBOSITY Override the default verbosity for this command. This
must be a standard logging verbosity level: [debug,
info, warning, error, critical, none] (Default:
[warning]).
-h Print a summary help and exit.
-v, --version Print version information.
command groups:
auth Manage oauth2 credentials for the Google Cloud SDK.
components List, install, update, or remove Google Cloud SDK
components or packages.
compute Read and manipulate Google Compute Engine resources.
config View and edit Google Cloud SDK properties.
container Deploy and manage clusters of machines for running
containers.
deployment-manager Manage deployments of cloud resources.
dns Manage your Cloud DNS managed-zones and record-sets.
sql Manage Cloud SQL databases.
topic gcloud supplementary help.
commands:
docker Provides the docker CLI access to the Google Container
Registry.
feedback Provide feedback to the Google Cloud SDK team.
help Prints detailed help messages for the specified
commands.
info Display information about the current gcloud
environment.
init Create and initialize a gcloud workspace in the current
directory.
version Print version information for Cloud SDK components. 然后使用gcloud登陆GCP账户（即，完成认证）：
然后，就可以做下面这些事情了：
Get started with a Google Cloud Platform service
With the Cloud SDK command-line interface, you can easily manage your service resources and your development workflow.
- Manage development workflow common to all services.
To get started, see the gcloud command-line tool. - Build a web app and host it on Google App Engine.
To get started, follow the walkthrough in the Developer Console to Try Google App Engine Now. - Launch large compute clusters on Google Compute Engine.
To get started, follow the Compute Engine Quickstart Guide. - Store vast amounts of data on Google Cloud Storage.
To get started, follow the Hello Google Cloud Storage Tutorial. - Analyze Big Data in the cloud with Google BigQuery.
To get started, follow the bq Command-Line Tool Quickstart. - Store and manage data using a MySQL database with Google Cloud SQL.
To get started, see Managing Instances Using the Cloud SDK. - Make your applications and services available to your users with Google Cloud DNS.
To get started, see Getting started with Google Cloud DNS.

比如，使用gcloud安装额外的一些组件：（可以参考gcloud的使用说明：https://cloud.google.com/sdk/gcloud/）
When you install the Google Cloud SDK, some components might be installed by default. To see a list of currently-installed components and a list of any available component updates, type the following command:
$ gcloud components list
To install additional components, type the update command, followed by the name of the component. For example, to installgsutil, type the following command:
$ gcloud components update gsutil
Running the above update command installs the gsutil tool into thegoogle-cloud-sdk/bin directory, and installs the tool's dependencies elsewhere in the Cloud SDK. If you correctly addedgoogle-cloud-sdk/bin to your PATH, you will be able to rungsutil from the command line.
To update all of your installed components, type gcloud components update.
先看下安装完gcloud默认安装了哪些组件：

To install new components or update existing ones, run:
$ gcloud components update COMPONENT_ID然后，使用gcloud安装kubectl：
root@gerryyang:~# gcloud components update kubectl

Update done!
WARNING: There are older versions of Google Cloud Platform tools on your system PATH.
Please remove the following to avoid accidentally invoking these old tools:
/root/Docker/tools/kubectl
设置gcloud的默认值：
-
Tell the command line interface which Google Developers Console project to use:
$ gcloud config set project PROJECTTo find the value of
PROJECT, visithttps://console.developers.google.com/projectand refer to theProject ID column. -
Set your default Compute Engine zone:
$ gcloud config set compute/zone ZONE -
If you've created a cluster, you can set it as the default so that you can omit the
--cluster CLUSTER_NAMEflag from your commands:$ gcloud config set container/cluster CLUSTER_NAME
To view your gcloud defaults at any time, run:
$ gcloud config list例如：
（5）接下来要做的事情。
Follow one of our walkthroughs to build an application from start to finish:
- Deploy Your Node.js Code
- Running WordPress with a Single Pod
- Create a Guestbook with Redis and PHP
- Using Persistent Storage with WordPress and MySQL
If you'd like to get started on your own, your first step is to create a container cluster.
