docker 容器中的 Running.env 文件

Question

I have been struggling to add env variables into my container for the past 3 hrs:( I have looked through the docker run docs but haven't managed to get it to work.

I have built my image using docker build -t sellers_json_analysis. which works fine.

I then go to run it with: docker run -d --env-file./env sellers_json_analysis

As per the docs: $ docker run --env-file./env.list ubuntu bash but I get the following error:

docker: open ./env: no such file or directory.

The .env file is in my root directory

But when running docker run --help I am unable to find anything about env variables, but it doesn't provide the following:

Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

So not sure I am placing things incorrectly. I could add my variables into the dockerfile but I want to keep it as a public repo as it's a project I would like to display.

Your problem is wrong path, either use .env or ./.env , when you use ./env it mean a file named env in current directory

docker run -d --env-file .env sellers_json_analysis
