Workaround to docker run “--env-file” supplied file not being evaluated as expected

Question

My current setup for running a docker container is on the lines of this:

1. I\'ve got a main.env file:

# Main
export PRIVATE_IP=\\`echo          


        

Answer 1

I had this issue when using docker run in a separate run script run.sh file, since I wanted the credentials ADMIN_USER and ADMIN_PASSWORD to be accessible in the container, but not show up in the command.

Following the other answers and passing a separate environment file with --env or --env-file didn't work for my image (though it worked for the Bash image). What worked was creating a separate env file...

# env.list
ADMIN_USER='username'
ADMIN_PASSWORD='password'

...and sourcing it in the run script when launching the container:

# run.sh
source env.list
docker run -d \
    -e ADMIN_USER=$INFLUXDB_ADMIN_USER \
    -e ADMIN_PASSWORD=$INFLUXDB_ADMIN_PASSWORD \
    image_repo/name:tag
