如何为boot2docker永久设置环境变量

I have tried to put my environment variable at /var/lib/boot2docker/profile file at guest machine, and restart it

我尝试将环境变量设置为/var/lib/boot2docker/profile文件，并重新启动它

export http_proxy=http://proxy:port

出口http_proxy = http://proxy:端口

then i open shell from my host machine (Windows 7) by using

然后我用我的主机(Windows 7)打开shell

docker-machine ssh default

docker-machine ssh违约

I can't find 'http_proxy' from my environment variable by using

我无法通过使用环境变量找到“http_proxy”

The docker daemon sources /var/lib/boot2docker/profile before starting. The HTTP_PROXY variable will be available in the docker daemons environment. Users logging in via ssh will not see this variable.

在启动之前，docker守护进程源/var/lib/boot2docker/profile。HTTP_PROXY变量将在docker守护进程环境中可用。通过ssh登录的用户将看不到这个变量。

Any /etc/profile.d/*.sh files will be loaded into a users profile at login but as you pointed out, this is reset back to the base image after every reboot.

任何/etc/profile.d/*.sh文件将在登录时加载到用户配置文件中，但正如您所指出的，这将在每次重新启动后重新设置为基本映像。

The /var/lib/boot2docker/ directory contains the files that are persisted over reboots. The bootlocal.sh will be run at the end of startup. bootsync.sh file will be run before docker.

/var/lib/boot2docker/目录包含在重新引导时持久化的文件。bootlocal。sh将在启动结束时运行。bootsync。sh文件将在docker之前运行。

Edit /var/lib/boot2docker/bootsync.sh to include

编辑/var/lib/boot2docker / bootsync。sh包括

echo 'export HTTP_PROXY="http://whatever"' > /etc/profile.d/proxy.sh

Then the variable will be available for anything that logs in after docker has started for the first time.

然后，对于docker第一次启动后登录的任何内容，该变量都是可用的。

○ → docker-machine restart default-docker
...
○ → docker-machine ssh default-docker
...
docker@default-docker:~$ echo $HTTP_PROXY
http://whatever

When PHPdocker.io generates a docker-compose.yml file, it also puts in a section for the environment variables.

当PHPdocker。io生成一个docker-compose。在yml文件中，它还包含了环境变量部分。

tie-mysql:
  image: mysql:5.7
  container_name: tie-mysql
  environment:
    - MYSQL_ROOT_PASSWORD=root
    - MYSQL_DATABASE=db_name
    - MYSQL_USER=db_user
    - MYSQL_PASSWORD=db_password

It starts running Docker-compose from the Vagrantfile:

它开始运行docker - composer从流浪文件:

config.vm.provision "shell", run: "always", 
      inline: "cd /home/docker/tie/phpdocker && docker-compose up -d 1>&2"

and if you aren't using docker-compose you could also arrange to put an appropriate file (like @Matt's /etc/profile.d/proxy.sh) into the virtual machine as it is being provisioned (with the config.vm.provision "shell"), rather than manually adding it later.

如果您没有使用docker-compose，您也可以安排将一个适当的文件(如@Matt的/etc/profile.d/proxy.sh)放入虚拟机中，因为它正在被配置(与config.vm一起)。提供“shell”，而不是稍后手动添加。

You can create a custom virtual machine with proxy configuration like this

您可以使用这样的代理配置创建一个自定义虚拟机

docker-machine create -d virtualbox --engine-env HTTP_PROXY=http://10.x.y.z:4951  --engine-env HTTPS_PROXY=https://10.x.y.z:4951 testbox

It will create a virtual machine with permanent proxy configuration.

它将创建一个具有永久代理配置的虚拟机。
