MacOS Sierra 10.12.2

Docker 1.12.5

Docker的新功能,每次我尝试构建Docker文件时都会出现此错误:

$ sudo docker build -t tutorial .
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

我按照SO帖子的说明进行操作,但问题并未解决: Docker can't connect to docker daemon

Docker版本:

$ docker --version
Docker version 1.12.5, build ...

目录:

$ ls
Dockerfile  README.md   apache      supervisord

启动Docker的虚拟机:

$ docker-machine start
Starting "default"...
Machine "default" is already running.
...
$ docker-machine env
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.00.00:2576" #edit
export DOCKER_CERT_PATH="/Users/myUser/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell: 
# eval $(docker-machine env)
...
$ eval "$(docker-machine env default)"

再次运行:

$ sudo docker build -t tutorial .
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

已解决:无法使用sudo

$ docker build -t tutorial .

尝试不使用docker build -t tutorial .运行此命令sudo或使用sudo运行eval "$(docker-machine env default)"
