#### Using a vagrant image from a previous version

 varnish:
image: varnish:6.0
restart: always
depends_on:
- apache
networks:
- frontend
- backend
- traefik
volumes:
- ./docker/varnish:/etc/varnish
ports:
- 6081:6081


I need the previous version of vagrant, I think it’s version 3.0, but the vagrant box I am using doesn’t allow it. Is there another vagrant box I can use with a prior version, because the VCL completely changed and I can’t test out the default.vcl file from the previous version.

vcl 4.0;

backend default {
.host = "apache:80";
}


This one works, but the one from production comes from an earlier version and vagrant version 6.0 throws an error when I am using the vcl file from production.
