That line is creating the global settings file in ~/.ddev/global_config.yaml and enables Mutagen for every future project per default. Just enter the following line into the terminal. That significantl elevates the performance for older Macs making them usable again with Docker. With the release of DDEV 1.8.0 the option of using Mutagen instead of the NFS filesystem got introduced. Since the Homebrew support is dropped for older versions of MacOS the most convenient option to install or update to latest version of DDEV and MKCERT is downloading and running the following line in the terminal: curl -LO & bash install_ddev.sh In case the suffix is something else go to ~/Library/Group Containers//settings.json and alter the filePath property from. Over all you adjust and play around with the assigned resources until you reach the sweet spot for your daily usage.įinally you should also make sure that the 'Disk image location' path ends with the file type Docker.raw to ensure you are using the latest image format for performance. There you are able to see how much CPU is utilized, the amount of memory is consumed, as well as the network i/o and block i/o and PIDS. docker stats aside the perceived experience provides further clues what ressources are consumed by the running ddev setup. In general you should play a bit with those settings and see what brings the best user experience.

In case you have more than 2 CPU cores available for your computer it makes also sense to tweak the limit of available cores to alleviating high I/O load. In case you have the available hardware resources quite a simple performance tweak would be increasing the RAM limit for Docker to half of the available amount on board tops. The defaults are usually fine for smaller projects. Īfter the install go to the Docker preference and into the resources tab. There are versions for even older revision of MacOS at.

For High Sierra the last supported version is Docker Desktop Community 2.4.0.0. To find a previous version not supported anymore you have to go to.
