I installed PhotonOS in a VM on VMware Fusion. The only things I changed where: allow root login trough SSH and I installed docker-compose
To play around I pulled a Nextcloud image and started the container. It couldn't start successfully because port 80 is in use from httpd on PhotonOS itself.
After I stopped httpd on PhotonOS the container could be started.
Is there any reason why httpd on PhotonOS should be started...?
