如果目标环境是远程的，将尝试 SSH 连接， 如果可以找到 Capistrano 配置。
Json
默认值将被漂亮地打印出来，但也可以在 JSON 中列出：
$ 12g env list -e [target environment name] -o json
-o 或 --output 设置输出格式。
Current environment
$ 12g env name
这将打印出当前环境的名称。
Docker shortcut
使用 12g dock [command] 直接在您的 Docker Compose 网络服务器上执行 Docker 命令。 它必须运行，并且必须遵守我们在 @grrr-amsterdam，这基本上是将您的 httpd 服务称为“web”。
示例：
$ 12g dock bash
$ 12g dock g spawn
$ 12g dock g snippet create
Shorthand
您可以在为常见环境名称提供的参数中使用简写语法：
pbecomesproductionsbecomesstagingibecomesintegrationdbecomesdevelopmenttbecomestesting
例如：
$ 12g env list -e s
列出staging 的环境。
12g
Administration tool for development and devops, according to the 12factor principles as applied by Grrr
Install
$ npm install -g 12g
Commands
Display help
$ 12g -h [command] [subcommand]
Environment
Create a template .env file
$ 12g env template
This will create a copy of your local .env file, named .env.template, with all values emptied.
Get variable from a .env file
$ 12g env get -e [target environment name] --var=DB_HOST
This will print the value from the environment variable set in the .env file on the target. Will return undefined if the variable is not set.
List variables from a .env file
$ 12g env list -e [target environment name]
This will list the variables from the .env file on the target, without quotes or comments. Target environment is probably development, staging, production, etcetera, depending on your setup.
If the targeted environment is remote, an SSH connection will be attempted, if Capistrano configuration can be found.
Json
Default the values will be pretty-printed, but listing in JSON is also possible:
$ 12g env list -e [target environment name] -o json
-o or --output sets the output format.
Current environment
$ 12g env name
This will print out the name of the current environment.
Docker shortcut
Use 12g dock [command] to execute a Docker command directly on your Docker Compose webserver. It has to be running and it will have to adhere to the naming standards as we use them at @grrr-amsterdam, which is basically calling your httpd service 'web'.
Examples:
$ 12g dock bash
$ 12g dock g spawn
$ 12g dock g snippet create
Shorthand
You can use shorthand syntax in the provided argument for common environment names:
pbecomesproductionsbecomesstagingibecomesintegrationdbecomesdevelopmenttbecomestesting
For instance:
$ 12g env list -e s
To list the environment for staging.
