I have created a .env file in my local system while developing a project. If I upload my project along with .env file, will it work fine or do i have to assign env variables separately?
According to the documentation it won't work like that.
You can set them in Console or provide with --set-env-vars flags during deployment from command line or set id Dockerfile with ENV parameter.

I need to inject env variables into my code.
I'm using azure pipelines to build my android app in react native.
I have set env variables in the build configuration and I have created a file called appcenter-post-clone.sh. The contents of this file are as follows:
ENV ADMIN_HOST= $ADMIN_HOST
And in my build configuration I have defined
ADMIN_HOST = https://example.com.
But I'm getting this error, [command]/bin/bash /Users/runner/runners/2.160.1/work/1/s/appcenter-post-clone.sh
ENV: https://example.com: No such file or directory. What I fail to understand here is, why is azure treating the value of my env variables as a file? How do I make this work?
The blunder I made here is, I should have used
ENV ADMIN_HOST=$ADMIN_HOST
Without the space. That solved it for me.
I'm using bitbucket pipelines as a build server.
I need to pass environmental variables from a host machine into a .env file which will then set the var values to be used in the build.
For example, lets say an environmental variable in a docker container running the build is AWS_ACCESS_KEY_ID.
In my .env file I'd like something like the following:
ACCESS_KEY=${AWS_ACCESS_KEY_ID}
I would then run the build and the ACCESS_KEY var would have a value equal to the env var in the docker container.
My current idea for a solution right now involves replacing values with sed, but that feels pretty hacky. Example:
.env file contains the following line:
ACCESS_KEY=<_access_key_replace_me_>
sed "s/<_access_key_replace_me_>/${AWS_ACCESS_KEY_ID}/g" .env
Any better solution than this?
I want to set up multiple paths in the user environmental variables in windows 10. but can only set a single path, how to overcome this issue?
If you want to add user defined environment variable then use react-native-config library. So in short if there are variables defined in .env file then you can use it anywhere in the react-native app like below:-
.env file
API_URL = "https://baseurl/endpoint"
//To use the above environment variable
import config react-native-config
function apiCall() { axios(config) }
With the help of react-native-config you can use environment variable in native code also and vise-versa.
For better use define .env.staging file. By default config lib finds .env file. To run the application with .env.staging file see below command.
$ ENVFILE=.env.staging react-native run-ios # bash
$ SET ENVFILE=.env.staging && react-native run-ios # windows
$ env:ENVFILE=".env.staging"; react-native run-ios # powershell

Happy coding mate :)
to add multiple paths for a single environment variable, list them all with a semicolon(";") in between like that:
C:\Cpp_Headers\pybind11;C:\Cpp_Headers\cpython\Include;C:\Users\admin\Cpp_Headers\cpython\PC
(and so forth). From this input Windows will automatically recognize multiple definitions.
I have a docker-compose file that contains a secret for my database.
port: 4466
managementApiSecret: ${DB_SECRET}
So I would like to use Docker-Compose's Variable Substitution (https://docs.docker.com/compose/compose-file/#variable-substitution) to be able to provide my secrets through an environment variable instead of my yaml file.
Is this at all possible using the "Application Settings" variables on my Azure Linux Docker Instance?
It doesn't seem to work for me, I've tried both ${VAR} and $VAR syntax and neither worked. I also tried with secrets that only contain alphanumerics and numbers.
Thanks in advance.

Environment variables that you need to start the container (for example: you want to include build number in container name) can be added to .env file in same directory as the docker-compose.yml file.
sample .env file:
DB_SECRET=foo
run: docker-compose config and verify that the variable has been substituted with the value you have in .env file
Also, I recommend using managementApiSecret:"${DB_SECRET}" (note the quotes around the variable) in your docker-compose.yml file
There might be azure specific way to share secrets but I didn't try that yet.
If you want to pass in environment variables that the container needs, then https://docs.docker.com/compose/compose-file/#env_file is what you want. Those environment vars will become part of environment inside docker container.
setting environmental variables for a Hubot is pretty easy on the production server. However when I want to test the bot locally, I need the env vars inside a file. I already have the file .env for env vars that heroku is using for running locally.
But I can't seem to find a way to load env vars inside the Hubot scripts from a file.
Merry Christmas :-)
okay it's possible with hubot-env.
https://www.npmjs.com/package/hubot-env
The following command will load the file from a relative path:
hubot env load --filename=[filename].
It previously didn't work for me because I had HUBOT_ENV_BASE_PATH set on my mac so the command searched in the wrong folder for the file.
