How do I undo the command $ eval "$(docker-machine env blog)"
提问by JAstuccio
I think that command redirected $ dockercommands to the docker machine. Now all my docker commands are giving me an error FATA[0000] Couldn't read ca cert...follwed by the path to the docker-machine I created. How can I fix my shell?
我认为该命令将$ docker命令重定向到 docker 机器。现在我所有的 docker 命令都给我一个错误FATA[0000] Couldn't read ca cert...，然后是我创建的 docker-machine 的路径。如何修复我的外壳？

What you are looking for is:
您正在寻找的是：
eval "$(docker-machine env -u)"
It will unset the DOCKER_*variables.
它将取消设置DOCKER_*变量。
For the record, here's the output of docker-machine env -u:
为了记录，这里是输出docker-machine env -u：
unset DOCKER_TLS_VERIFY
unset DOCKER_HOST
unset DOCKER_CERT_PATH
unset DOCKER_MACHINE_NAME

You could also restart your shell. This will drop the variables that minkube docker-envexports.
您也可以重新启动您的外壳。这将删除minkube docker-env导出的变量。

I had been searching for an answer to this for quite awhile. Shortly after posting the question on stackoverflow I realized typing in to the terminal the export commands docker gives on startup resolved my issue.
我一直在寻找这个问题的答案很长一段时间。在stackoverflow上发布问题后不久，我意识到在终端中输入docker在启动时给出的导出命令解决了我的问题。
To connect the Docker client to the Docker daemon, please set:
export DOCKER_HOST=tcp:// some IP address
export DOCKER_CERT_PATH= some file path
export DOCKER_TLS_VERIFY=1

I can see that this is an old post but if someone else runs into this issue, who is new to docker like me this can help. By typing:
我可以看到这是一个旧帖子，但是如果其他人遇到这个问题，像我这样的 docker 新手这可以提供帮助。通过键入：
eval $(docker-machine env nameOfVm)
you are setting your current shell to use docker in that docker-machine. You can check if you type docker-machine lsthat under active tab, that status is changed from - to *for that machine. You can also check which machine is active by running docker-machine active.
您正在设置当前的 shell 以在该 docker-machine 中使用 docker。您可以检查您docker-machine ls是否在活动选项卡下键入，- to *该机器的状态已更改。您还可以通过运行来检查哪台机器处于活动状态docker-machine active。
If you want to undo eval, just run:
如果要撤消 eval，只需运行：
eval $(docker-machine env -u)
and it will unset variables for active machine (You don't have to specify the name of the machine). This is all under macOS but I think it should be same on linux as well. You can read more about this here: Docker documentation: docker-machine env
它将取消活动机器的变量设置（您不必指定机器的名称）。这都是在 macOS 下，但我认为在 linux 上也应该是一样的。您可以在此处阅读更多相关信息： Docker 文档：docker-machine env
