小编scu*_*dev的帖子

虽然我写了相当数量的厨师,但我对AWS/VPC和管理网络流量(尤其是堡垒主机)都很陌生.

使用刀ec2插件,我希望能够从我的开发人员工作站动态创建和引导VM.VM应该能够存在于我的VPC的公共或私有子网中.我想在不使用弹性IP的情况下完成所有这些工作.我也希望我的堡垒主机可以放手(即我希望避免在我的堡垒主机上创建明确的每个VM侦听隧道)

我已成功使用刀ec2插件在传统EC2模型中创建VM(例如,在我的VPC之外).我现在正在尝试在我的VPC中创建一个实例.在knife命令行中,我指定了一个网关,安全组,子网等.虚拟机被创建,但是之后刀无法ssh到它.

这是我的刀命令行:

knife ec2 server create \
    --flavor t1.micro \
    --identity-file <ssh_private_key> \
    --image ami-3fec7956 \
    --security-group-ids sg-9721e1f8 \
    --subnet subnet-e4764d88 \
    --ssh-user ubuntu \
    --server-connect-attribute private_ip_address \
    --ssh-port 22 \
    --ssh-gateway <gateway_public_dns_hostname (route 53)> \
    --tags isVPC=true,os=ubuntu-12.04,subnet_type=public-build-1c \
    --node-name <VM_NAME>

我怀疑我的问题与我的堡垒主机的配置有关.经过一天的谷歌搜索,我无法找到有效的配置.我可以ssh到堡垒主机,从那里我可以ssh到新创建的VM.我无法使用gateway参数成功复制此刀.

我玩过/ etc/ssh/ssh_config.今天它是如何存在的:

    ForwardAgent yes
#ForwardX11 no
#ForwardX11Trusted yes
#RhostsRSAAuthentication no
#RSAAuthentication yes
#PasswordAuthentication no
#HostbasedAuthentication yes
#GSSAPIAuthentication no
#GSSAPIDelegateCredentials no
#GSSAPIKeyExchange no
#GSSAPITrustDNS no
#BatchMode no
   CheckHostIP no
#AddressFamily any
#ConnectTimeout 0
    StrictHostKeyChecking no
    IdentityFile ~/.ssh/identity …

我正在尝试为我的DAO对象创建一个JUnit测试.JUnit直接从Netbeans运行.我对其中的几种技术都很陌生,因此我有一段时间可以追踪我的错误来自何处.我的代码和我看到的相应错误是:
