Pass argument to docker compose

docker-compose variables
docker-compose environment variables not set
docker-compose multiple env files
dockerfile arguments
pass argument to docker-compose up
docker-compose build-arg
docker build args
docker run arguments example

In my docker compose file there is a dynamic field which I'd like to generate during the running. Actually it is a string template:


And I want to configure this PORT parameter dynamically

docker-compose run <service> PORT=443

In documentation there is ARGS parameters set I suppose I can use. But there is no information how can I use those inside compose file

In docker-compose, arguments are available and usefull only in dockerfile. You can specify what you are doing in the level ahead like following:


Your port can be set in your docker-compose.yml:

  context: .
    - PORT=443

It is actually an environment variable in any case. You can pass it through your run command if that fits to you:

PORT=443 docker-compose run <service>
docker-compose run <service> -e PORT=443

How to pass arguments within docker-compose?, This feature was added in Compose 1.6. Reference:​compose/compose-file/#args services: web: build: context: . args:  TEST= docker-compose up to create and start both app and db container. The api should then be running on your docker daemon on port 3030. TEST=DO docker-compose up to create and start both app and db container. The api should execute the npm run test inside the package.json file.

You can use the flag when using docker-compose build

docker-compose build --build-arg PRODUCTION=VALUE

In Dockerfile you can get the argument PRODUCTION

# Dockerfile
FROM node:latest

Understanding Docker Build Args, Environment Variables and , I struggled with understanding how to pass variables to Docker images, and In docker-compose, you can specify values to pass on for ARG, in an args block:. 1 Answer 1. Please (re)read the docker-compose docs, in docker-compose.yml command refers to the actual command executed inside the container, not the options you pass to docker run. Your example translates to: To detach after container start use docker-compose up -d.

See this answer. You can do it like this: PORT=433 docker-compose <command>

You can even provide multiple values: PORT=433 MYIP='' docker-compose <command>

Environment variables in Compose, You can pass environment variables from your shell straight through to a service's containers  How to pass environment variables to Docker compose with a make file Posted on 13th May 2020 by danieldergrosse We have a line in our Makefile which reads the env file and exports the variables to the shell:

This is possible to with stack deploy

Example Compose File in your environment section:


Stack Deploy Command (I ran this from Gitbash in Windows):

MY_VARIABLE_VALUE=some-value docker stack deploy --compose-file compose_file_here stackname

Docker-compose config: how to pass arguments, I'm not sure it's correct, but I used to use $ docker-compose config to verify if final docker-compose configuration merged from multiple files is  docker-compose is a great tool for orchestrating multiple docker instances. But it is not like kubernetes or docker swarm. Rather, its a simple application which allows you to communicate between docker containers, allow you to easily configure things, even help you generate service, route, build config etc for kubernetes if you use kompose

Docker & ENV: Methods for Passing Variables through Docker , Passing environment variables into your Docker build process and Pass variables into Docker Compose during the `build` or `up` process. Docker Compose allows us to pass environment variables in via command line or to define them in our shell. However, it’s recommended to keep these values inside the actual Compose file and out of

Using Variables in Docker-Compose - Better Programming, Docker Compose allows us to pass environment variables in via command line or to define them in our shell. However, it's recommended to  The default path for a Compose file is ./docker-compose.yml. Tip: You can use either a .yml or .yaml extension for this file. They both work. A service definition contains configuration that is applied to each container started for that service, much like passing command-line parameters to docker container create.

Variables in Docker Compose, Docker Compose starts containers in dependency order by using the depends_on option We can even pass environment variables through to our containers:. Use Case: You need to run a custom shell script in your Docker container with arguments passed to the script. These arguments decide how the script should be run inside the container. In this guide, we will look int to running custom shell scripts inside a Docker container with command line arguments.
