Hi. I’m new to docker and probably I don’t understand something about relation between containers.
Lets say I have
docker-compose.yml version 3 with Nginx+PHP. How do I add image vitr/casperjs so I can call it from PHP like
exec('/what/is/the/path casperjs --version', $output);
? Is it something about the volume? Is it something about the dependents?
I struggled a lot but i just don’t get it. Casperjs works fine with
$ docker exec my_alias_for_casperjs casperjs --version
but i can’t access it with PHP. How do i?
Is it okay to merge PHP, PhantoJS and Casper JS into single Dockerfile?
