+# this is to make the wp_cron job works
+# ! it might not be a very strong solution

+# somehow it didn't work if the local adress is not accessible from inside the wordpress container :
+# if : `curl <PROJECT_URL>` don't work, the cron job does not either (why ?)
+# to make it work, i mapped the docker network gateway ip to the url (without understanding what i'm doing)
+# the default network is named bridge, and it's gateway is 172.17.0.1 : https://docs.docker.com/network/network-tutorial-standalone/
+# also might help, even though i didn't use, it helped me find the ip 172.17.0.1 : https://stackoverflow.com/questions/24319662/from-inside-of-a-docker-container-how-do-i-connect-to-the-localhost-of-the-mach?rq=2
