docker工人造成stream浪箱子失败

我有一个任务，在一个stream浪者箱子（centos / 7）中创build一些Docker容器，但是我遇到了“stream浪汉”的执行问题。

在stream浪的实例中，我使用docker合成来启动服务。

这是我在调用docker-compose时遇到的错误：

> ==> default: [Provisioning] Bring up Docker Containers > ==> default: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running? > ==> default: > ==> default: If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable. 

如果我检查stream浪者实例，我可以看到docker工人正在运行，而且我的用户是docker组的一部分

 c:\temp\vagrant\kpi-engine>vagrant ssh [vagrant@localhost ~]$ ps aux | grep docker root 425 0.1 4.6 496652 23152 ? Ssl 09:54 0:00 /usr/bin/dockerd root 428 0.0 1.0 265176 5360 ? Ssl 09:54 0:00 docker-containerd -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --shim do cker-containerd-shim --metrics-interval=0 --start-timeout 2m --state-dir /var/run/docker/libcontainerd/containerd --runtime docker-runc vagrant 1363 0.0 0.1 112652 972 pts/0 S+ 09:55 0:00 grep --color=auto docker [vagrant@localhost ~]$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [vagrant@localhost ~]$ grep vagrant /etc/group vagrant:x:1000:vagrant docker:x:992:vagrant 

但是，如果我在“stream浪汉”之后运行“stream浪汉条款”，所有事情都可以顺利通过Docker。

 ==> default: [Provisioning] Clone repositories ==> default: fatal: destination path 'kpi_data' already exists and is not an empty directory. ==> default: [Provisioning] Bring up Docker Containers ==> default: Creating network "vagrant_default" with the default driver ==> default: Creating volume "vagrant_mongo_db" with default driver ==> default: Creating volume "vagrant_maria_db" with default driver ==> default: Pulling mariadb (docker-registry.ptk02.ipaccess.com/mariadb:latest)... ==> default: latest: Pulling from mariadb ==> default: Digest: sha256:d17cfbf8e7e9b9ed79f2de17125a01f66f350ddf5bcdd8b62da20634cfa0b425 ==> default: Status: Downloaded newer image for docker-registry.ptk02.ipaccess.com/mariadb:latest ==> default: Pulling mongo (docker-registry.ptk02.ipaccess.com/mongo:latest)... ==> default: latest: Pulling from mongo ==> default: Digest: sha256:4059a5c7c1f7d44a0ea3c1f8bda0e240f74f8cf16d6cc08e81d0fbc59b475553 ==> default: Status: Downloaded newer image for docker-registry.ptk02.ipaccess.com/mongo:latest ==> default: Creating mongo ==> default: Creating mariadb 

Docker使用vagrant provisioner安装

 config.vm.provision :docker 

我用–debug跑了“stream浪汉”，但没有提供更多的见解。

任何想法可能是什么问题。
