environment-variables

问题 I am deploying a create-react-app Service onto Google Cloud Run using a Dockerfile, but I want to move away from declaring env variables in a .env file, and instead, declare them on Google Cloud Run's Dashboard like so: However, when I call the env var using console.log("REDIRECT", process.env.REACT_APP_REDIRECT_URI) null is returned for any env variable I try to reference. Is there another step to access these variables that I am missing? Here is my Dockerfile: FROM node:10-alpine as react

问题 Is there some java utility, which will expand ~ and env. variables in a string? Like "~/bin;${MY_PATH}" -> "/home/john/bin;/dev/null" Thank you 回答1: Basically, you want to do String interpolation with environment variables and expand home directories. I don't know of an easy way to do the latter, but if you use Spring to do your set-up you can use it's PropertyPlaceholderConfigurer to replace placeholders in strings. By default, environment variables are included in the set of placeholder

问题 My OS is Ubuntu 12.04, I have installed separately Apache, Php and Mysql. I've never had a problem, but after an Ubuntu update I always get a "404 Not Found" error when I try to access a php file on my web server.

问题 I need to write a unit test for some C++ code that checks for the presence of an environmental variable. I'm using MSVS 2008 and gtest as my framework. I add the environmental variable using putenv, I check the environmental variable using getevn, but I can't figure out how to remove it so that no other test will see it. I realize this is probably easy, but I can't find the answer on the internet. Thanks 回答1: Calling putenv again specifying "SOME_VAR=" as parameter will delete environment

问题 I added the key into heroku config var, but I'm still getting the error. Is this the correct way? I ignored secrets.yml as I read from other sources that its not a good idea to push this to the public. in the heroku config var: [key] SECRET_KEY_BASE [value] 3280570382948240938 in secrets.yml production: secret_key_base: <%= ENV["SECRET_KEY_BASE"] %> What am I still doing wrong? Furthermore, if I put my secret keys into heroku's config variable, don't other developers get to see this too? So,
