django - 通过 shell 记录时未设置 Docker 环境变量

Question

在我的设置文件中，我得到了这样的环境变量

'NAME': os.environ['PG_DBNAME'],  # Database

我正在像这样在 docker 文件中设置

-e PG_DBNAME= "mapp"

现在

1. 网络应用运行良好
2. 如果我通过 docker exec ... bash 登录到 shell，那么 env 变量也会被设置

但是如果我通过 ssh 客户端的 ipaddress 和端口号登录，那么我可以登录但未设置 env 变量

Answer 1

正如 issue 2569 中的评论:

This is expected. SSH wipes out the environment as part of the login process.

One way to work around it is to dump the environment variables in /etc/environment (e.g. env | grep _ >> /etc/environment) before starting Supervisor.
Further "login processes" should source this file, and tada! There is your environment.

那个env | grep _ >>/etc/environment 可能是与您的图像关联(通过 ENTRYPOINT 或 CMD)的默认运行脚本的一部分。

Daniel A.A. Pelsmaeker建议jenkinsci/docker-ssh-agent issue 33对于选择和设置除特定拒绝名单之外的所有环境变量的方法:

For my own uses I changed that line to the following:

env | egrep -v "^(HOME=|USER=|MAIL=|LC_ALL=|LS_COLORS=|LANG=|HOSTNAME=|PWD=|TERM=|SHLVL=|LANGUAGE=|_=)" >> /etc/environment

This takes all environment variables, except those listed, and appends then to /etc/environment, overriding any previously defined there.
