How to connect google bucket on upload?

Question

Google Cloud Platform

I can not connect storage, when loading.
found an example of a service for systemd, edited it for myself.

[Unit]
Description=Google Cloud Storage FUSE mounter
After=local-fs.target network-online.target google.service sys-fs-fuse-connections.mount
Before=shutdown.target
[Service]
Type=forking
User=apache
ExecStart= /bin/gcsfuse --key-file=/home/alexeymish/test1-087057f69913.json dtco-rsync-dst /mnt/dtco-rsync-dst
ExecStop=/bin/fusermount -u /mnt/dtco-rsync-dst
Restart =always
[Install]
WantedBy=multi-user.target

But here the launch is on behalf of Apache, I don’t have such a user.
Tell me how to edit the config correctly?
Should I put the key-file in /home/user or will there be problems accessing it?
