According to the official Docker documentation, proxy related envionment variables of the host are readily available as build arguments. My situation is the following:
- Host machine has no environment proxy variables, but has a proxy configuration in
Dockerfilefor the images makes no use of the proxy build arguments nor envionment variables
- Containers have proxy environment variables setted with the values configured in the
I don’t want the proxy variables in the container, why are they being configured? How can I prevent this from happening?
I’m using as a base image
php:7.3-apache-buster. It’s Dockerfile doesen’t seem to have any use of the proxy env variables. Could the problem be with their image?
I get this problem running containers with
docker run and
docker-compose up, but the variables are not in the containers if I use
docker stack deploy.
