By using docker I created container in windows after that I got requirement like need to add environment variables for existing container for that I wrote script by using “-e” flag like as shown below

docker run -d -t -i -e environment_variable container_name

In above syntax we need to replace environment_variable with your required variable name and container_name with your containerid

Example
