I was just wondering how can i point to two env-files, say /var/app/old/file.conf and /var/market/old/db.conf , both in the command line as I find there is support for mutiple -e flags. Does Docker supports pointing to multiple env-file in a command line like the one below
docker run -d --hostname=158.64.72.80 -d -p 80:80 --env-file /var/app/old/file.conf --env-file /var/market/old/db.conf
228
With a Command Line Argument The command used to launch Docker containers, docker run , accepts ENV variables as arguments. Simply run it with the -e flag, shorthand for --env , and pass in the key=value pair: sudo docker run -e POSTGRES_USER='postgres' -e POSTGRES_PASSWORD='password' ...
One solution is to have multiple . env files which each represent different environments. In practice this means you create a file for each of your environments: .
Multiple commands can be executed in a running Docker container using the docker exec command. If the Docker container is stopped, before running the docker exec command it should be started using the docker run command.
You can pass the values of environment variables from the host to your containers without much effort. Simply don't specify a value in the command line, and make sure that the environment variable is named the same as the variable the containerized app expects: $ docker run -e var_name (...)
You can do exactly like the command you are running already. For example:
file1
GGG=/home/ppp
file2
HHH=/ter/ssd
Then run the Docker command:
docker run -it --env-file=/Users/user/file1 --env-file=/Users/users/file2 centos:6.6 /bin/bash
Then once in the container:
[user@99964c311fef ~]# env
HOSTNAME=99964c311fef
TERM=xterm
