There's a lot of programs out there that can utilize .env files. Most of them support the basic bash-syntax, others support more advanced things like templating within the .env files. The way you're supposed to use .env files varies a lot as well.
Is it possible to list all environment variables from a Windows' command prompt? Something equivalent to PowerShell's gci env: (or ls env: or dir env:).
Consider if your .env was created with the following code: printf '%s\n' 'password="two words"' 'another=foo' >.env. In that case, the arguments passed to export would be password=two , words , and another=foo ; words would no longer be part of the password , and would be a separate argument on its own (so the command would be trying to export a preexisting variable with the name words ).
gci env:* ls Env: However, I have a script being called from another program, and when I use one of the above calls in the script, instead of being presented with environment variables and their values, I instead get a list of System.Collections.DictionaryEntry types instead of the variables and their values.
I am using a base.env as an env_file for several of my docker services.In this base.env I have several parts of the environment variable that repeat throughout the file. For example, port and ip are the same for three different environment variables.
You can use ENV for environment variables to use during the build and in containers. With this Dockerfile: FROM ubuntu ARG BUILD_TIME=abc ENV RUN_TIME=123 RUN touch /env.txt RUN printenv > /env.txt You can override the build arg as you have done with docker build -t temp --build-arg BUILD_TIME=def .. Then you get what you expect:
I'd like to add a few comments: - You cannot have empty lines in your .env file - Comments in your .env file will break your script - If multiple scripts use the same .env file, you will have to repeat that - I had to remove the space before && for it to work - If you have multiple .env files, it may be a little harder to maintain Your answer inspired me to prepare this suggestion ...
That way when I use cygwin or something that can't read windows env variables, I still have a quick way of swapping versions. And it's much easier to remember the shorter path without the minor version. –
I would like to know how I can display the location of Program Files (x86) in Command Prompt. I'm using Windows 7 64bit.
docker run --rm -it --env-file <(bash -c 'env | grep <your env data>') Is a way to grep the data stored within a .env and pass them to Docker, without anything being stored unsecurely (so you can't just look at docker history and grab keys. Say you have a load of AWS stuff in your .env like so:
