Generic folder structure for docker:

/home/sysadmin/dock
/home/sysadmin/apps

In this case, you should create a homepage and a code-server folder in the apps/ folder:

/home/sysadmin/apps/homepage
/home/sysadmin/apps/code-server

Make sure they have have the right permissions:

sudo chown -R 1000:1000 /home/sysadmin/apps/homepage
sudo chown -R 1000:1000 /home/sysadminapps/code-server
