At the moment CMA has a few limitations that you should be aware of:

  • You can create a maximum of 30 CMA instances running at the same time before running into network limits. To remove custom networks not used by at least one container you can use the command docker network prune OR update to magento-scripts version 1.7.0 or newer which will remove project network during stop command, freeing the network.

  • Not all ports can be used for Magento to run on. Some browsers can throw an error ERR_UNSAFE_PORT on some ports below 1024. If you encountered such issue, use -p option in the start command and use ports above 1024.
