Question

我使用JClouds-Chef API通过Chef Client引导Linux VM（myapp01.me.example.com），然后运行客户端并通过typicalapp配置VM及其应用堆栈作用：

package com.me.myorg.chef;

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();
        }
    }
}

当我跑步时，我得到：

关于这里发生了什么的任何想法？

Answer 1

为了能够引导您的VM，您将需要以下内容：

VM的IP地址。它必须是可访问的，端口22打开（因为引导程序将通过SSH完成）并且可以访问Internet，因此它可以安装Ruby和Chef。
Chef Server中的客户端及其对应的私钥。 jclouds使用该客户端来执行针对Chef Server REST API的操作。
验证者证书。该证书将上传到节点，以便它可以在Chef服务器中自行注册。

在这种情况下，由于未使用jclouds ComputeService，您必须手动实例化SSH客户端以连接到虚拟机，但它应该非常简单。

在您提到的示例中，使用ChefSolo时会克隆Git仓库，但由于您拥有Chef服务器，因此您唯一需要做的就是配置连接以及所需的运行列表和属性。

执行此操作的最小程序需要以下依赖项：

<!-- 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>

它可能类似于以下内容：

更新：我已更改配置以匹配提供的 knife.rb 配置，并且还添加了一些属性以避免SSL错误，因为您的Chef端点是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();
}

JClouds-Chef：TokenType2上的IllegalAccessError？
