为什么容器无法在DC / OS中获取URI？
我已经在Digital Ocean（DC / OS 1.9）上创build了一个使用terraform的集群，遵循这些指示
一切似乎已经正确安装，从私人docker回购，我需要添加一个压缩的.docker文件到我的/core/home/和部署期间通过将其包含在我的JSON中获取它。
"fetch":[ { "uri":"file:///home/core/docker.tar.gz" } ]
根据这些说明： https ： //docs.mesosphere.com/1.9/deploying-services/momee/docker-creds-agent/
而我仍然遇到错误：
Failed to launch container: Failed to fetch all URIs for container 'abc123-xxxxx' with exit status: 256
在查看其中一个代理的日志时：

您错过了解压缩指令：
"fetch":[ { "uri":"file:///home/core/docker.tar.gz", "extract":true } ]
