I have an environment variable defined in my windows settings as a user variable.
It is called GITLAB_AUTH_TOKEN.
In my Dockerfile I am trying to assign this variable to an environment variable called GAT like so:
ENV GAT=${GITLAB_AUTH_TOKEN}
This results in the GAT env var to be blank inside my container.
I have seen that it may be possible via docker-compose but that is not a solution for me, as my RUN command relies on this variable.
I have several environment variable from a text.txt file , i set them with export variable = value manually one by one myself in terminal Ubuntu 18.04 but now no one of them appear in printenv !
I need to set them somehow never remove again(unless i delete them myself).any idea?thank you
Add your variables in ~/.bashrc or in /etc/environment this way on every reboot they will be exported.
in bashrc should be like this
export VARIABLE='<value>'
in /etc/environment
VARIABLE=<value>
I tried to get the variable in docker-compose.yml like ${NODE_ENV} but doesn't work.
Also I don't want to send any param on my commands. I have defined already an environment variable on my system and I'd like to take that one from either one of these 2 files.
the solution was running export NODE_ENV=development again. I was losing this env var every time I was closing the terminal
When I hit the cmd set in csh it shows me a list of env variables I have right now in my session.
I was wondering where they are set/saved and couldn't find the location.
I have tried in files ~/.cshrc and ~/.cshrc.myusername and in both I saw none of the environment variables that set shows .
Where are they?
In memory. Each instance of csh will get a new copy of your default environment. Setting variables at the command prompt does not persist them anywhere for future sessions.
When I use vim to update my environmental variables (in ~/.bashrc), PyCharm does not get the updates right away. I have to shut down the program, source ~/.bashrc again, and re-open PyCharm.
Is there any way to have PyCharm source the changes automatically (or without shutting down)?
When any process get created it inherit the environment variables from it's parent process (the O.S. itself in your case). if you change the environment variables at the parent level, the child process is not aware of it.
PyCharm allows you to change the environment variables from the Run\Debug Configuration window.
Run > Edit Configurations > Environment Variables ->
In my case pycharm does not take env variables from bashrc even after restarting
Pycharm maintains it's own version of environment variables and those aren't sourced from the shell.
It seems that if pycharm is executed from a virtualenv or the shell containing said variables, it will load with them, however it is not dynamic.
the answer below has a settings.py script for the virtualenv to update and maintain settings. Whether this completely solves your question or not i'm not sure.
Pycharm: set environment variable for run manage.py Task
I recently discovered a workaround in windows. Close Pycharm, copy the command to run Pycharm directly from the shortcut, and rerun it in a new terminal window: cmd, cmder, etc.
C:\
λ "C:\Program Files\JetBrains\PyCharm 2017.2.1\bin\pycharm64.exe"
I know this is very late, but I encountered this issue as well and found the accepted answer tedious as I had a lot of saved configurations already.
The solution that a co-worker told me is to add the environment variables to ~/.profile instead. I then had to restart my linux machine and pycharm picked up the new values. (for OSX, I only needed to source ~/.profile and restart pycharm completely)
One thing to be aware is that another coworker said that pycharm would look at ~/.bash_profile so if you have that file, then you need the environment variables added there
In case you are using the "sudo python" technique, be aware that it does not by default convey the environment variables.
To correctly pass on the environment variables defined in the PyCharm launch configuration, use the -E switch:
sudo -E /path/to/python/executable "$#"
This is simply how environment variables work. If you change them you have to re-source your .bashrc (or whatever file the environment variables are located in).
from dotenv import load_dotenv
load_dotenv(override=True)
Python-dotenv can interpolate variables using POSIX variable expansion.
With load_dotenv(override=True) or dotenv_values(), the value of a variable is the first of the values defined in the following list:
Value of that variable in the .env file.
Value of that variable in the environment.
Default value, if provided.
Empty string.
With load_dotenv(override=False), the value of a variable is the first of the values defined in the following list:
Value of that variable in the environment
Value of that variable in the .env file.
Default value, if provided.
Empty string.
