With these it helps I dont want to repeat myself, can I do something like this?: , It should get what you are looking for:
ENV VAR1=sdfsdf \
    VAR2=dlksjdlfks \
    VAR3=1.2.3
...
LABEL VA1=$VAR1 \
      VA2=$VAR2 \
      VA3=$VAR3

How to get the hostname of the docker host from inside a docker container on that host without env vars


Tag : docker , By : k19k

Does that help You can pass in the hostname as an environment variable. You could also mount /etc so you can cat /etc/hostname. But I agree with Vitaly, this isn't the intended use case for containers IMO.

Docker seems to ignore DOCKER_HOST and other vars set from `eval $(docker-machine env)`

seems to work fine From the comments, your docker command was aliased to sudo docker. The sudo command will not pass through the environment variables defined by docker-machine so it will default back to the /var/lib/docker.sock.
As for which vs type, which will point to a binary in the $PATH to let you know where something is located. type will let you know how the shell is running that command including shell built-ins, any aliases, or function definitions.

docker-compose: start service from same docker-compose file using env vars to alter container name


Tag : docker , By : Dmitry

it fixes the issue Rather than mucking about with variables in docker-compose.yml, it's probably easier just to make use of the --project-name (-p) option to docker-compose.
Normally, docker-compose derives the project name from the name of the directory that contains your docker-compose.yaml file. So if two people try to start an application from a directory named myapp, they will end up with a conflict because both instances will attempt to use the same name.
docker-compose --project-name ${USER}_myapp ...
COMPOSE_PROJECT_NAME=alice_myapp

Missing Environment Vars in docker python:3 with docker-compose


Tag : python , By : Josh

hop of those help? The RUN is used only when building image. The CMD is the command that is started when you start container from your image. If you run migrate when building image it is wrong, migrate is building your database and you want to run it each time before runserver
# Dockerfile -- api

FROM python:3

RUN pip3 -q install -r requirements.txt
RUN echo `$DJANGO_SECRET_KEY`
CMD /bin/bash -c "python manage.py migrate --settings=falcon.settings.dev-microservice && python manage.py runserver 0.0.0.0:8001 --settings=falcon.settings.dev-microservice"
