File directory:
.env
docker-compose.yml
.env:
-sharp
ROOT_PATH=./services
-sharp
WWW_PATH=./www
-sharp nginx
NGINX_WWW_DIR=$(WWW_PATH)
docker-compose.yml
- ${NGINX_WWW_DIR}:/data/www:rw
: Named volume "WWW_PATH:/data/www:rw" is used in service "nginx" but no declaration was found in the volumes section.
question:
.env? NGINX_WWW_DIR=$(WWW_PATH)
you should remove the parentheses here
= >
NGINX_WWW_DIR=$WWW_PATH
or change to curly braces
NGINX_WWW_DIR=${WWW_PATH}
but according to the docker volume mapping rules, it is best to use the absolute path, that is,
NGINX_WWW_DIR=$PWD/$WWW_PATH
-v should only accept absolute path.
I think of combining variables myself in docker-compose.yml.
such as $(ROOT_PATH) $(SUB_PATH)
