我现在用的是JClouds厨师 API来引导一个Linux VM（ myapp01.me.example.com ）与厨师客户端，并再运行客户端，并通过其应用程序堆栈配置VM typicalapp作用： 

package com.me.myorg.chef;

import org.jclouds.Constants
import org.jclouds.ContextBuilder
import org.jclouds.chef.ChefContext

import com.google.common.collect.ImmutableSet
import com.google.common.io.Files
import com.google.common.net.HostAndPort
import com.google.inject.Key
import com.google.inject.TypeLiteral

public class ChefProvisioner {
    public static void main(String[] args) {
        ChefProvisioner.provision()
    }

    public static provision() {
        String vmIp = "myapp01.me.example.com";     // A Linux VM living in our local vCenter
        String vmSshUsername = "admin";
        String vmSshPassword = "12345";

        String endpoint = "https://mychefserver";
        String client = "myuser";
        String validator = "chef-validator";
        String clientCredential = Files.toString(new File("C:\\Users\\myuser\\sandbox\\chef\\myuser.pem"), Charsets.UTF_8);
        String validatorCredential = Files.toString(new File("C:\\Users\\myuser\\sandbox\\chef\\chef-validator.pem"), Charsets.UTF_8);

        Properties props = new Properties();
        props.put(ChefProperties.CHEF_VALIDATOR_NAME, validator);
        props.put(ChefProperties.CHEF_VALIDATOR_CREDENTIAL, validatorCredential);
        props.put(Constants.PROPERTY_RELAX_HOSTNAME, "true");
        props.put(Constants.PROPERTY_TRUST_ALL_CERTS, "true");

        ChefContext ctx = ContextBuilder.newBuilder("chef")
            .endpoint(endpoint)
            .credentials(client, clientCredential)
            .overrides(props)
            .modules(ImmutableSet.of(new SshjSshClientModule())) //
            .buildView(ChefContext.class);
        ChefService chef = ctx.getChefService();

        List<String> runlist = new RunListBuilder().addRole("typicalapp").build();
        BootstrapConfig bootstrapConfig = BootstrapConfig.builder().runlist(runlist).build();

        chef.updateBootstrapConfigForGroup("jclouds-chef", bootstrapConfig);
        Statement bootstrap = chef.createBootstrapScriptForGroup("jclouds-chef");

        SshClient.Factory sshFactory = ctx.unwrap().utils()
            .injector().getInstance(Key.get(new TypeLiteral<SshClient.Factory>() {}));
        SshClient ssh = sshFactory.create(HostAndPort.fromParts(vmIp, 22),
        LoginCredentials.builder().user(vmSshUsername).password(vmSshPassword).build());

        ssh.connect();
        try {
            String rawScript = bootstrap.render(OsFamily.UNIX);
            ExecResponse result = ssh.exec(rawScript);
        } finally {
            ssh.disconnect();
        }
    }
}

当我运行此我得到：

任何想法，这是怎么回事？

Answer 1:

你将需要以下，为了能够引导你的虚拟机：

  • 虚拟机的IP地址。 它必须是可达的，有22端口打开（如引导将通过SSH进行），并具有接入互联网，因此它可以安装Ruby和厨师。
  • 厨师服务器在客户端和其相应的私钥。 该客户端使用jclouds兑厨师服务器REST API执行的操作。
  • 验证证书。 该证书将被上传到节点，以便它可以在厨师服务器自行注册。

在这种情况下，如不使用jclouds ComputeService，你必须手动实例化一个SSH客户端连接到虚拟机，但它应该是相当简单的。

在你提到的例子中，Git的回购使用ChefSolo当克隆，但因为你有一个厨师服务器，你需要做的唯一一件事就是配置连接和所需的运行列表和属性。

一个最小的程序要做到这一点就需要下面的依赖关系： 

<!-- Required dependencies -->
<dependency>
    <groupId>org.apache.jclouds.driver</groupId>
    <artifactId>jclouds-sshj</artifactId>
    <version>${jclouds.version}</version>
</dependency>
<dependency>
    <groupId>org.apache.jclouds.api</groupId>
    <artifactId>chef</artifactId>
    <version>${jclouds.version}</version>
</dependency>

它可能是类似以下内容：

更新：我已经改变了配置，以匹配提供knife.rb配置，同时还增加了几个属性，以避免SSL错误，因为你的厨师终点为https。 

// Configuration
String vmIp = "vm-ip";
String vmSshUsername = "root";
String vmSshPassword = "foo";

String endpoint = "https://mychefserver.example.com";
String client = "myuser";
String validator = "chef-validator";
String clientCredential = Files.toString(new File("/home/myuser/.chef/myuser.pem"), Charsets.UTF_8);
String validatorCredential = Files.toString(new File("/home/myuser/.chef/chef-validator.pem"), Charsets.UTF_8);

Properties props = new Properties();
props.put(ChefProperties.CHEF_VALIDATOR_NAME, validator);
props.put(ChefProperties.CHEF_VALIDATOR_CREDENTIAL, validatorCredential);
props.put(Constants.PROPERTY_RELAX_HOSTNAME, "true");
props.put(Constants.PROPERTY_TRUST_ALL_CERTS, "true");

/* *** First, create the context to connect to the Chef Server *** */

// Create the context and configure the SSH driver to use. sshj in this example
ChefContext ctx = ContextBuilder.newBuilder("chef")
    .endpoint(endpoint)
    .credentials(client, clientCredential)
    .overrides(props)
    .modules(ImmutableSet.of(new SshjSshClientModule())) //
    .buildView(ChefContext.class);
CherService chef = ctx.getChefService();

/* *** Second, generate the bootstrap script *** */

// Generate the bootsrap configuration
List<String> runlist = new RunListBuilder().addRole("typicalapp").build();
BootstrapConfig bootstrapConfig = BootstrapConfig.builder().runlist(runlist).build();

// Generate the bootstrap script to be executed in the VM (this will persist
// the configuration in a data bag under the key 'jclouds-chef' so it can be reused
// and then build the bootstrap script with the information in the configuration data bag)
chef.updateBootstrapConfigForGroup("jclouds-chef", bootstrapConfig);
Statement bootstrap = chef.createBootstrapScriptForGroup("jclouds-chef");

/* *** Finally create an SSH connection manually and run the script on the VM *** */

SshClient.Factory sshFactory = ctx.unwrap().utils()
    .injector().getInstance(Key.get(new TypeLiteral<SshClient.Factory>() {}));
SshClient ssh = sshFactory.create(HostAndPort.fromParts(vmIp, 22),
    LoginCredentials.builder().user(vmSshUsername).password(vmSshPassword).build());

ssh.connect();
try {
    String rawScript = bootstrap.render(OsFamily.UNIX);
    ExecResponse result = ssh.exec(rawScript);
} finally {
    ssh.disconnect();
}
