[英]How to incorporate Environments with JClouds-Chef API?
我正在使用JClouds-Chef :
重要的是要注意,我當前配置Chef所需要的只是一個角色(僅此而已;其他所有設置都在Chef服務器上為我完成):
public class ChefClient {
public configure() {
String vmIp = "myapp01.example.com";
String vmSshUsername = "myuser";
String vmSshPassword = "12345";
String endpoint = "https://mychefserver.example.com";
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("platformcontrol_dev").build();
ArrayList<String> runList2 = new ArrayList<String>();
for(String item : runlist) {
runList2.add(item);
}
BootstrapConfig bootstrapConfig = BootstrapConfig.builder().runList(runList2).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 {
StringBuilder rawScript = new StringBuilder();
Map<String, String> resolvedFunctions = ScriptBuilder.resolveFunctionDependenciesForStatements(
new HashMap<String, String>(), ImmutableSet.of(bootstrap), OsFamily.UNIX);
ScriptBuilder.writeFunctions(resolvedFunctions, OsFamily.UNIX, rawScript);
rawScript.append(bootstrap.render(OsFamily.UNIX));
ssh.put("/tmp/chef-bootstrap.sh", rawScript.toString());
ExecResponse result = ssh.exec("bash /tmp/chef-bootstrap.sh");
} catch(Throwable t) {
println "Exception: " + t.message
} finally {
ssh.disconnect();
}
}
}
現在,我們的內部“廚師”(我們的開發人員)除現有角色外,還希望將廚師“ 環境 ”的概念添加到我們的所有食譜中。 這樣我們就可以為每個節點指定特定於環境的角色。 我的問題:JClouds-Chef API是否可以處理環境? 如果是這樣,我將如何修改代碼以包含特定於環境的角色?
就像這樣簡單嗎:
BootstrapConfig bootstrapConfig = BootstrapConfig.builder()
.environment("name-of-env-here?").runList(runList2).build();
是的,就是這么簡單。 這將告訴引導腳本在指定的環境中注冊該節點。
但是,請考慮到該環境必須已經在Chef Server中存在 。 如果要在新環境中創建節點,則還可以按照以下方式以編程方式創建它們:
ChefApi api = ctx.unwrapApi(ChefApi.class);
if (api.getEnvironment("environment-name") == null) {
Environment env = Environment.builder()
.name("environment-name")
.description("Some description")
.build();
api.createEnvironment(env);
}
