Aug 19, 2016 - Expected behavior Amount of disk space used under ~/Library/Containers/com.docker.docker/ should shrink when deleting images and/or. There are many various improvements you can make to Docker for Mac to fine-tune performance, especially when working with large application filesystems such as those with Magento or Zend Framework. Step 1: Computer, Cores & RAM I'm absolutely resolved that a dual-core machine with 8GB RAM will just simply not cut it. My MacBook Air just spins fans, and fswatch events get delayed or stop working just because there is not enough computing power to go around. Once you have (at the very least) a quad-core MacBook Pro with 16GB RAM and an SSD, go to Docker > Preferences > Advanced. Set the 'computing resources dedicated to Docker' to at least 4 CPUs and 8.0 GB RAM. Step 2: Docker Disk Type Next, go to Disk settings. Be sure the 'Disk image location' value ends with the file type 'Docker.raw'. The new raw filesystem ensures you are using the latest image format for performance. If you don't see this or instead see something like 'qcow2', edit the filePath property of the file ~/Library/Group Containers/group.com.docker/settings.json extension from.qcow2 to. Raw, and restart Docker for Mac. Next, set the Overlay2 Filesystem in Daemon > Advanced. Basically, you want to add a property of 'storage-driver': 'overlay2'. For more information on this, see. Note that all previous containers, images and Docker data will be reset and lost with either of these changes, so it's best to apply before doing any other tweaks or performance updates. Step 3: Disable Unneeded File Shares By default, Docker for Mac comes with '/Users', '/Volumes', '/private', and '/tmp' directories available to bind mount into Docker containers. Remove all of these. Add the root location of where your website files and composer home are located. For me, this is '/Users/myusername/Sites' as well as '/Users/myusername/.composer'. These are most likely the only folders you need to bind-mount to Docker. This makes sure Docker is not unnecessarily listening for filesystem changes in other locations. Then I contacted them about which program folders to back up so I would not lose my configurations and he could not (Or would not) tell me. I wanted to get a walk thru of the platform when it first funded (The account rep. Had said that I would get a walk thru and could be trading next day) but the help desk guy said all he could do was refer me to their setup guy and schedule an appointment, but the first available appointment was 4 weeks out. Best mac for photography. Step 4: Use 'delegated' Volume Mounts This is a, and isn't nearly used enough. The 'delegated' flag is the one you want to use. This postpones writes back to the host in order to achieve higher filesystem throughput. Enjoy your modified Docker setup! Hope you experience much better performance as Docker for Mac continues to get better each day. Over time a guest's *.qcow2 disk files can grow larger than the actual data stored within them, this happens because the Guest OS normally only marks a deleted File as zero, it doesn't gets actually deleted (performance reasons), so the underlying qcow2 file cannot differentiate between allocated and used and allocated but not used storage. In order to shrink the *.qcow2 files you've two options, enable TRIM support or zero out all free space of the partitions contained within the guest and then reconvert the image with qemu-img. IMPORTANT WARNING: Always have offsite backups ready, you never know! Contents • • • • • • • • • Recommended Solution The recommended version is to pass TRIM commands (known from SSDs) from the VM to the backing storage. This has the advantage that it works automatically, does not need to write the whole free parts of all disks to zero and must only be setup once. PVE Configuration Requirements: • Thin-provisioned backing storage (qcow2 disk, thin-lvm, zfs.) • Virtio-SCSI controller configured on guest. • Guest scsi* disks with the discard option enabled • See for configuration details. Linux Guest Configuration Modern Linux guest systems can use the well known fstrim command to trim a device and free all unused storage on the underlying device: fstrim -av Many modern Linux distributions have already setup a timer or cron job which executes a TRIM about once a week. Windows Guest Configuration For those Windows versions which support TRIM (Win7/2008R2 and up should be supported, see ) you should not have to setup anything, Windows should periodically trigger a TRIM to the disks.
