问题描述
我正在尝试使用Android Test Station。我下载了Android Test Station CLI并运行了./mtt start，但是没有启动UI。然后，我运行docker exec -it mtt cat /data/log/server/current将日志获取到docker之外。这是日志

似乎Cloud Datastore Emulator返回503“服务不可用”。
但是我确定Cloud Datastore Emulator正在通过top命令运行。
在python脚本中添加一些日志，我得到启动Cloud Datastore Emulator的命令，
'/usr/lib/google-cloud-sdk/platform/cloud-datastore-emulator/cloud_datastore_emulator','start','--testing','--regenerate_indexes=false','--auto_id_policy=SCATTERED','--port=8007','--store_on_disk=true','--store_index_configuration_on_disk=true','--index_file=/mtt/index.yaml','--storage_file=/tmp/mtt/datastore.db','--require_indexes','/tmp/tmpwvDVWT'。
此命令是否有问题？谁能说出为什么出现503错误？
解决方法
更新：
我找到了原因。我在.docker / config.json中添加了no_proxy设置，它可以正常工作！ 如果您有类似的问题，只需将noProxy设置为“ localhost，127.0.0.1，metadata.google.internal”即可解决。
