symfony classes.map failed to open stream: No such file or directory
I get this error when I tried to deploy symfony in a Docker swarm node
ContextErrorException in Kernel.php line 338:
Warning: file_put_contents(/home/backend_microservice/private_webapp/var/cache/dev/classes.map): failed to open stream: No such file or directory
I tried to remove the cache manually, I remove the vendor directory and I generate a new one with composer, but still give the same error.
The same config works fine with only docker engine but does not work in swarm mode.
OS : CentOS 7.3
Virtualization : Docker version 17.06.0-ce, build 02c1d87 Swarm mode
Any help or suggestion??
thank you in advance.
