Question

我创建了一个Scala项目，该项目使用两个Docker的容器（奇异性/ datastore-emulator和bigtruedata / gcloud-pubsub-emulator）创建了一个testcontainer（通过com.dimafeng.testcontainers）。成功创建了testcontainer，当我运行docker ps命令时，这就是我看到的内容：

CONTAINER ID        IMAGE                               COMMAND             CREATED             STATUS              PORTS                     NAMES
ddc16471205a        quay.io/testcontainers/ryuk:0.2.2   "/app"              2 minutes ago       Up 2 minutes        0.0.0.0:32771->8080/tcp   testcontainers-ryuk-371a41c2-3d23-426f-943d-608a816c96d3

现在，当我尝试运行容器时会出现问题：

$ docker run -p 4000:80 quay.io/testcontainers/ryuk:0.2.2
2018/12/13 10:59:48 Starting on port 8080...
panic: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

goroutine 1 [running]:
main.main()
    /go/src/github.com/bsideup/moby-ryuk/main.go:31 +0xe2e

如果我进入容器并运行/ app命令，这就是我得到的：

$ docker exec -it ddc /bin/sh
/ # /app
2018/12/13 11:40:55 Starting on port 8080...
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x64f8d6]

goroutine 9 [running]:
main.main.func1(0xc4200685a0, 0xc4201bd890, 0xc420068600)
    /go/src/github.com/bsideup/moby-ryuk/main.go:42 +0x286
created by main.main
    /go/src/github.com/bsideup/moby-ryuk/main.go:39 +0x1b5

从设置docker-machine eval默认值到检查所有可能的权限问题，我实际上已经尝试了所有方法。我想念什么？

（我根本无法访问出现在错误中的go文件）

这是有关我的docker安装的信息
