docker 若干错误 - Shuang0420/Shuang0420.github.io GitHub Wiki

docker的新手，在用 Scrapy-Splash 时遇到的错误。

错误1

$ docker run -p 8050:8050 scrapinghub/splash
Post http:///var/run/docker.sock/v1.20/containers/create: dial unix /var/run/docker.sock: no such file or directory.
* Are you trying to connect to a TLS-enabled daemon without TLS?
* Is your docker daemon up and running?

解决

Start boot2docker-vm

查看 docker service 是不是在 run。

$ ps aux | grep docker

发现没有启动，start it.

$ boot2docker start

  WARNING: The 'boot2docker' command line interface (not to be confused with
  'boot2docker' the operating system) is officially deprecated.

  Please switch to Docker Machine (https://docs.docker.com/machine/) ASAP.

  Docker Toolbox (https://docker.com/toolbox) is the recommended install method.
