Cloud Foundry 运行bosh create-env时

在Linux上使用Bosh创建Director的时候报错，如下：

bosh create-env bosh-deployment/bosh.yml \
  --state state.json \
  --vars-store ./creds.yml \
  -o bosh-deployment/virtualbox/cpi.yml \
  -o bosh-deployment/virtualbox/outbound-network.yml \
  -o bosh-deployment/bosh-lite.yml \
  -o bosh-deployment/jumpbox-user.yml \
  -v director_name=vbox \
  -v internal_ip=192.168.50.6 \
  -v internal_gw=192.168.50.1 \
  -v internal_cidr=192.168.50.0/24 \
  -v network_name=vboxnet0 \
  -v outbound_network_name=NatNetwork

...
Deploying:
  Creating instance 'bosh/0':
    Waiting until instance is ready:
      Post https://mbus:<redacted>@192.168.50.6:6868/agent: net/http: TLS handshake timeout

解决办法：

编辑 bosh-deployment/virtualbox/cpi.yml 文件，将其中 memory 由 4096 改成 2048。然后重新运行bosh create-env 命令。
