Big thanks to @kholia for maintaining the upstream project, which Docker-OSX is built on top of: OSX-KVM.
Also special thanks to @thenickdude who maintains the valuable fork KVM-OpenCore, which was started by @Leoyzen!
Extra special thanks to the OpenCore team over at: https://github.com/acidanthera/OpenCorePkg. Their well-maintained bootloader provides much of the great functionality that Docker-OSX users enjoy :)
If you like this project, consider contributing here or upstream!

This is a particularly good way for downloading the container, in case Docker's CDN (or your connection) happens to be slow.
wget https://images2.sick.codes/mac_hdd_ng_auto.img
docker run -it \
--device /dev/kvm \

Enable SSH in network sharing inside the guest first. Change -e "USERNAME=user" and -e "PASSWORD=password" to your credentials. The container will add itself to ~/.ssh/authorized_keys
Since you can't see the screen, use the PLIST with nopicker, for example:
# Catalina
# wget https://images2.sick.codes/mac_hdd_ng_auto.img
# Monterey
wget https://images.sick.codes/mac_hdd_ng_auto_monterey.img
docker run -it \

sickcodes/docker-osx:naked-autoThe easiest and most secure way is sshfs
# on Linux/Windows
mkdir ~/mnt/osx
sshfs user@localhost:/ -p 50922 ~/mnt/osx
# wait a few seconds, and ~/mnt/osx will have full rootfs mounted over ssh, and in userspace
# automated: sshpass -p <password> sshfs user@localhost:/ -p 50922 ~/mnt/osxIf you have a laptop see the next usbfluxd section.
If you have a desktop PC, you can use @Silfalion's instructions: https://github.com/Silfalion/Iphone_docker_osx_passthrough
Video setup tutorial for usbfluxd is also available here: https://www.youtube.com/watch?v=kTk5fGjK_PM
This method WORKS on laptop, PC, anything!
Thank you @nikias for usbfluxd via https://github.com/corellium!
This is done inside Linux.
Open 3 terminals on Linux
Connecting your device over USB on Linux allows you to expose usbmuxd on port 5000 using https://github.com/corellium/usbfluxd to another system on the same network.
Ensure usbmuxd, socat and usbfluxd are installed.
sudo pacman -S libusbmuxd usbmuxd avahi socat
Available on the AUR: https://aur.archlinux.org/packages/usbfluxd/
yay usbfluxd
Plug in your iPhone or iPad.
Terminal 1
sudo systemctl start usbmuxd
sudo avahi-daemonTerminal 2:
# on host
sudo systemctl restart usbmuxd
sudo socat tcp-listen:5000,fork unix-connect:/var/run/usbmuxdTerminal 3:
sudo usbfluxd -f -nThis is done inside macOS.
Install homebrew.
172.17.0.1 is usually the Docker bridge IP, which is your PC, but you can use any IP from ip addr...
macOS Terminal:
# on the guest
brew install make automake autoconf libtool pkg-config gcc libimobiledevice usbmuxd
git clone https://github.com/corellium/usbfluxd.git
cd usbfluxd
./autogen.sh
make
sudo make installAccept the USB over TCP connection, and appear as local:
(you may need to change 172.17.0.1 to the IP address of the host. e.g. check ip addr)
# on the guest
sudo launchctl start usbmuxd
export PATH=/usr/local/sbin:${PATH}
sudo usbfluxd -f -r 172.17.0.1:5000Close apps such as Xcode and reopen them and your device should appear!
If you need to start again on Linux, wipe the current usbfluxd, usbmuxd, and socat:
sudo killall usbfluxd
sudo systemctl restart usbmuxd
sudo killall socatMake container FASTER using https://github.com/sickcodes/osx-optimizer
SEE commands in https://github.com/sickcodes/osx-optimizer!
- Skip the GUI login screen (at your own risk!)
- Disable spotlight indexing on macOS to heavily speed up Virtual Instances.
- Disable heavy login screen wallpaper
- Disable updates (at your own risk!)
Increase disk space by moving /var/lib/docker to external drive, block storage, NFS, or any other location conceivable.
Move /var/lib/docker, following the tutorial below
- Cheap large physical disk storage instead using your server's disk, or SSD.
- Block Storage, NFS, etc.
Tutorial here: https://sick.codes/how-to-run-docker-from-block-storage/
Only follow the above tutorial if you are happy with wiping all your current Docker images/layers.
Safe mode: Disable docker temporarily so you can move the Docker folder temporarily.
- Do NOT do this until you have moved your image out already https://github.com/dulatello08/Docker-OSX/#quick-start-your-own-image-naked-container-image
killall dockerd
systemctl disable --now docker
systemctl disable --now docker.socket
systemctl stop docker
systemctl stop docker.socketNow, that Docker daemon is off, move /var/lib/docker somewhere
Then, symbolicly link /var/lib/docker somewhere:
mv /var/lib/docker /run/media/user/some_drive/docker
ln -s /run/media/user/some_drive/docker /var/lib/docker
# now check if /var/lib/docker is working still
ls /var/lib/dockerIf you see folders, then it worked. You can restart Docker, or just reboot if you want to be sure.

Before you do anything else, you will need to turn on hardware virtualization in your BIOS. Precisely how will depend on your particular machine (and BIOS), but it should be straightforward.
Then, you'll need QEMU and some other dependencies on your host:
# ARCH
sudo pacman -S qemu libvirt dnsmasq virt-manager bridge-utils flex bison iptables-nft edk2-ovmf
# UBUNTU DEBIAN
sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager libguestfs-tools
# CENTOS RHEL FEDORA
sudo yum install libvirt qemu-kvmThen, enable libvirt and load the KVM kernel module:
sudo systemctl enable --now libvirtd
sudo systemctl enable --now virtlogd
echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs
sudo modprobe kvmRunning Docker-OSX on Windows is possible using WSL2 (Windows 11 + Windows Subsystem for Linux).
You must have Windows 11 installed with build 22000+ (21H2 or higher).
First, install WSL on your computer by running this command in an administrator powershell. For more info, look here.
This will install Ubuntu by default.
wsl --install
You can confirm WSL2 is enabled using wsl -l -v in PowerShell. To see other distributions that are available, use wsl -l -o.
If you have previously installed WSL1, upgrade to WSL 2. Check this link to upgrade from WSL1 to WSL2.
After WSL installation, go to C:/Users/<Your_Name>/.wslconfig and add nestedVirtualization=true to the end of the file (If the file doesn't exist, create it). For more information about the .wslconfig file check this link. Verify that you have selected "Show Hidden Files" and "Show File Extensions" in File Explorer options.
The result should be like this:
[wsl2]
nestedVirtualization=true
Go into your WSL distro (Run wsl in powershell) and check if KVM is enabled by using the kvm-ok command. The output should look like this:
INFO: /dev/kvm exists
KVM acceleration can be used
Use the command sudo apt -y install bridge-utils cpu-checker libvirt-clients libvirt-daemon qemu qemu-kvm to install it if it isn't.
Now download and install Docker for Windows if it is not already installed.
After installation, go into Settings and check these 2 boxes:
General -> "Use the WSL2 based engine";
Resources -> WSL Integration -> "Enable integration with my default WSL distro",
Ensure x11-apps is installed. Use the command sudo apt install x11-apps -y to install it if it isn't.
Finally, there are 3 ways to get video output:
- WSLg: This is the simplest and easiest option to use. There may be some issues such as the keyboard not being fully passed through or seeing a second mouse on the desktop - Issue on WSLg - but this option is recommended.
To use WSLg's built-in X-11 server, change these two lines in the docker run command to point Docker-OSX to WSLg.
-e "DISPLAY=${DISPLAY:-:0.0}" \
-v /mnt/wslg/.X11-unix:/tmp/.X11-unix \
Or try:
-e "DISPLAY=${DISPLAY:-:0}" \
-v /mnt/wslg/.X11-unix:/tmp/.X11-unix \
For Ubuntu 20.x on Windows, see #458
- VNC: See the VNC section for more information. You could also add -vnc argument to qemu. Connect to your mac VM via a VNC Client. Here is a how to
- Desktop Environment: This will give you a full desktop linux experience but it will use a bit more of the computer's resources. Here is an example guide, but there are other guides that help set up a desktop environment. DE Example
Additional boot instructions for when you are creating your container
-
Boot the macOS Base System (Press Enter)
-
Click
Disk Utility -
Erase the BIGGEST disk (around 200gb default), DO NOT MODIFY THE SMALLER DISKS. -- if you can't click
erase, you may need to reduce the disk size by 1kb -
(optional) Create a partition using the unused space to house the OS and your files if you want to limit the capacity. (For Xcode 12 partition at least 60gb.)
-
Click
Reinstall macOS -
The system may require multiple reboots during installation
This is a great place to start if you are having trouble getting going, especially if you're not that familiar with Docker just yet.
Just looking to make a container quickly? Check out our container creation examples section.
More specific/advanced troubleshooting questions and answers may be found in More Questions and Answers. You should also check out the closed issues. Someone else might have gotten a question like yours answered already even if you can't find it in this document!
See initial setup.
docker: unknown server OS: .
See 'docker run --help'.This means your docker daemon is not running.
pgrep dockerd should return nothing
Therefore, you have a few choices.
sudo dockerd for foreground Docker usage. I use this.
Or
sudo systemctl --start dockerd to start dockerd this now.
Or
sudo systemctl --enable --now dockerd for start dockerd on every reboot, and now.
Examples:
-e EXTRA='-smp 6,sockets=3,cores=2'
-e EXTRA='-smp 8,sockets=4,cores=2'
-e EXTRA='-smp 16,sockets=8,cores=2'
Note, unlike memory, CPU usage is shared. so you can allocate all of your CPU's to the container.
If you use sudo dockerd or dockerd is controlled by systemd/systemctl, then you must be in the Docker group.
If you are not in the Docker group:
sudo usermod -aG docker "${USER}"and also add yourself to the kvm and libvirt groups if needed:
sudo usermod -aG libvirt "${USER}"
sudo usermod -aG kvm "${USER}"See also: initial setup.
# run ad hoc
sudo dockerd
# or daemonize it
sudo nohup dockerd &
# enable it in systemd (it will persist across reboots this way)
sudo systemctl enable --now docker
# or just start it as your user with systemd instead of enabling it
systemctl start dockerBig thank you to our contributors who have worked out almost every conceivable issue so far!

Created a container with docker run and want to reuse the underlying image again later?
NB: see container creation examples first for how to get to the point where this is applicable.
This is for when you want to run the SAME container again later. You may need to use docker commit to save your container before you can reuse it. Check if your container is persisted with docker ps --all.
If you don't run this you will have a new image every time.
# look at your recent containers and copy the CONTAINER ID
docker ps --all
# docker start the container ID
docker start -ai abc123xyz567
# if you have many containers, you can try automate it with filters like this
# docker ps --all --filter "ancestor=sickcodes/docker-osx"
# for locally tagged/built containers
# docker ps --all --filter "ancestor=docker-osx"
You can also pull the .img file out of the container, which is stored in /var/lib/docker, and supply it as a runtime argument to the :naked Docker image.
See also: here.
Containers that use sickcodes/docker-osx:auto can be stopped while being started.
# find last container
docker ps -a
# docker start old container with -i for interactive, -a for attach STDIN/STDOUT
docker start -ai -i <Replace this with your ID>You may see one or more libgtk-related errors if you do not have everything set up for hardware virtualisation yet. If you have not yet done so, check out the initial setup section and the routine checks section as you may have missed a setup step or may not have all the needed Docker dependencies ready to go.
See also: here.
If you have not yet set up xhost, try the following:
echo $DISPLAY
# ARCH
sudo pacman -S xorg-xhost
# UBUNTU DEBIAN
sudo apt install x11-xserver-utils
# CENTOS RHEL FEDORA
sudo yum install xorg-x11-server-utils
# then run
xhost +
You cannot allocate more RAM than your machine has. The default is 3 Gigabytes: -e RAM=3.
If you are trying to allocate more RAM to the container than you currently have available, you may see an error like the following: cannot set up guest memory 'pc.ram': Cannot allocate memory. See also: here, here.
For example (below) the buff/cache already contains 20 Gigabytes of allocated RAM:
[user@hostname ~]$ free -mh
total used free shared buff/cache available
Mem: 30Gi 3.5Gi 7.0Gi 728Mi 20Gi 26Gi
Swap: 11Gi 0B 11GiClear the buffer and the cache:
sudo tee /proc/sys/vm/drop_caches <<< 3Now check the RAM again:
[user@hostname ~]$ free -mh
total used free shared buff/cache available
Mem: 30Gi 3.3Gi 26Gi 697Mi 1.5Gi 26Gi
Swap: 11Gi 0B 11GiNote: AppleALC, alcid and VoodooHDA-OC do not have codec support. However, IORegistryExplorer does show the controller component working.

sickcodes/docker-osxIt's possible to forward additional ports depending on your needs. In this example, we'll use Mac OSX to host nginx:
host:10023 <-> 10023:container:10023 <-> 80:guest
On the host machine, run:
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
-e ADDITIONAL_PORTS='hostfwd=tcp::10023-:80,' \
-p 10023:10023 \
sickcodes/docker-osx:autoIn a Terminal session running the container, run:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install nginx
sudo sed -i -e 's/8080/80/' /usr/local/etc/nginx/nginx.confcd
# sudo nginx -s stop
sudo nginxnginx should now be reachable on port 10023.
Additionally, you can string multiple statements together, for example:
-e ADDITIONAL_PORTS='hostfwd=tcp::10023-:80,hostfwd=tcp::10043-:443,'
-p 10023:10023 \
-p 10043:10043 \You might not need to do anything with the default setup to enable internet connectivity from inside the container. Additionally, curl may work even if ping doesn't.
See discussion here and here and here.
This is not required for LOCAL installations.
Additionally note it may cause the host to leak your IP, even if you're using a VPN in the container.
However, if you're trying to connect to an instance of Docker-OSX remotely (e.g. an instance of Docker-OSX hosted in a datacenter), this may improve your performance:
# enable for current session
sudo sysctl -w net.ipv4.ip_forward=1
# OR
# sudo tee /proc/sys/net/ipv4/ip_forward <<< 1
# enable permanently
sudo touch /etc/sysctl.conf
sudo tee -a /etc/sysctl.conf <<EOF
net.ipv4.ip_forward = 1
EOF
# or edit manually with the editor of your choice
nano /etc/sysctl.conf || vi /etc/sysctl.conf || vim /etc/sysctl.conf
# now rebootSharing a folder with guest is quite simple.
Your folder, will go to /mnt/hostshare inside the Arch container which is then passed over QEMU.
Then mount using sudo -S mount_9p hostshare from inside the mac.
For example,
FOLDER=~/somefolder -v "${FOLDER}:/mnt/hostshare" \
-e EXTRA="-virtfs local,path=/mnt/hostshare,mount_tag=hostshare,security_model=passthrough,id=hostshare" \Full example:
# stat mac_hdd_ng.img
SHARE=~/somefolder
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \

# !!! Open Terminal inside macOS and run the following command to mount the virtual file system

To share a folder using NFS, setup a folder for on the host machine, for example, /srv/nfs/share and then append to /etc/exports:
/srv/nfs/share 127.0.0.1/0(insecure,rw,all_squash,anonuid=1000,anongid=985,no_subtree_check)You may need to reload exports now, which will begin sharing that directory.
# reload shared folders
sudo exportfs -arvGive permissions on the shared folder for the anonuid and anongid, where anonuid and anongid matches that of your linux user; id -u
id -u ; id -g will print userid:groupid
chown 1000:985 /srv/nfs/share
chmod u+rwx /srv/nfs/share
Start the Docker-OSX container with the additional flag --network host
Create and mount the nfs folder from the mac terminal:
mkdir -p ~/mnt
sudo mount_nfs -o locallocks 10.0.2.2:/srv/nfs/share ~/mnt
Start your container.
Pick a port, for example, 7700.
lsusb to get vid:pid
On Linux:
sudo usbredirserver -p 7700 1e3d:2096
Now, in the Docker window hit Enter to see the (qemu) console.
You can add/remove the disk using commands like this, even once the machine is started:
chardev-add socket,id=usbredirchardev1,port=7700,host=172.17.0.1
device_add usb-redir,chardev=usbredirchardev1,id=usbredirdev1,debug=4

-e EXTRA="-chardev socket,id=usbredirchardev1,port=${PORT},host=${IP_ADDRESS} -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,debug=4" \`Fedora's default firewall settings may prevent Docker's network interface from reaching the internet. In order to resolve this, you will need to whitelist the interface in your firewall:
# Set the docker0 bridge to the trusted zone
sudo firewall-cmd --permanent --zone=trusted --add-interface=docker0
sudo firewall-cmd --reloadCheck if your machine has hardware virtualization enabled:
sudo tee /sys/module/kvm/parameters/ignore_msrs <<< 1
egrep -c '(svm|vmx)' /proc/cpuinfo-e NETWORKING=vmxnet3
-e NETWORKING=e1000-82545em
- Start the container as usual, and remove unnecessary files. A useful way
to do this is to use
du -sh *starting from the/directory, and find large directories where files can be removed. E.g. unnecessary cached files, Xcode platforms, etc. - Once you are satisfied with the amount of free space, enable trim with
sudo trimforce enable, and reboot. - Zero out the empty space on the disk with
dd if=/dev/zero of=./empty && rm -f empty - Shut down the VM and copy out the qcow image with
docker cp stoppedcontainer:/home/arch/OSX-KVM/mac_hdd_ng.img . - Run
qemu-img check -r all mac_hdd_ng.imgto fix any errors. - Run
qemu-img convert -O qcow2 mac_hdd_ng.img deduped.imgand check for errors again - OPTIONAL: Run
qemu-img convert -c -O qcow2 deduped.img compressed.imgto further compress the image. This may reduce the runtime speed though, but it should reduce the size by roughly 25%. - Check for errors again, and build a fresh docker image. E.g. with this Dockerfile
FROM sickcodes/docker-osx
USER arch
COPY --chown=arch ./deduped.img /home/arch/OSX-KVM/mac_hdd_ng.img
First make sure autoboot is enabled
Next, you will want to set up SSH to be automatically started.
sudo systemsetup -setremotelogin onMake sure to commit the new docker image and save it, or rebuild as described in the section on reducing disk space.
Then run it with these arguments.

First step is to stop the docker daemon
sudo systemctl stop docker
The second step is to change container config in
/var/lib/docker/containers/[container-id]/config.v2.json
(Suppose your original WIDTH is 1024 and HEIGHT is 768, you can search 1024 and replace it with the new value. Same for 768.)
The last step is to restart the docker daemon
sudo systemctl restart docker
Pass the disk into the container as a volume and then pass the disk again into QEMU command line extras with.
Use the config-custom.plist because you probably want to see the boot menu, otherwise omit the first line:

In Docker-OSX, we are using qcow2 images.
This means the image grows as you use it, but the guest OS thinks you have 200GB available.
READ ONLY
# mount the qemu image like a real disk
sudo modprobe nbd max_part=8
sudo qemu-nbd --connect=/dev/nbd0 ./image.img
sudo fdisk /dev/nbd0 -l
mkdir -p ./mnt
sudo mount /dev/nbd0p1 ./mnt
# inspect partitions (2 partitions)
sudo fdisk /dev/nbd0 -l
# mount using apfs-linux-rw OR apfs-fuse
mkdir -p ./part
sudo mount /dev/nbd0p2 ./part
sudo apfs-fuse -o allow_other /dev/nbd0p2 ./part
When you are finishing looking at your disk, you can unmount the partition, the disk, and remove the loopback device:
sudo umount ./part
sudo umount ./mnt
sudo qemu-nbd --disconnect /dev/nbd0
sudo rmmod nbdFirstly, QEMU must be started as root.
It is also potentially possible to accomplish USB passthrough by changing the permissions of the device in the container. See here.
For example, create a new Dockerfile with the following
FROM sickcodes/docker-osx
USER arch
RUN sed -i -e s/exec\ qemu/exec\ sudo\ qemu/ ./Launch.sh
COPY --chown=arch ./new_image.img /home/arch/OSX-KVM/mac_hdd_ng.imgWhere new_image.img is the qcow2 image you extracted. Then rebuild with docker build .
Next we need to find out the bus and port numbers of the USB device we want to pass through to the VM:
lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M
|__ Port 2: Dev 5, If 0, Class=Human Interface Device, Driver=usbhid, 12M
|__ Port 2: Dev 5, If 1, Class=Chip/SmartCard, Driver=, 12M
|__ Port 3: Dev 2, If 0, Class=Wireless, Driver=, 12M
|__ Port 3: Dev 2, If 1, Class=Wireless, Driver=, 12M
|__ Port 5: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M
|__ Port 5: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480MIn this example, we want to pass through a smartcard device. The device we want is on bus 1 and port 2.
There may also be differences if your device is usb 2.0 (ehci) vs usb 3.0 (xhci). See here for more details.
# hostbus and hostport correspond to the numbers from lsusb
# runs in privileged mode to enable access to the usb devices.

mycustomimageYou should see the device show up when you do system_profiler SPUSBDataType in the MacOS shell.
Important Note: this will cause the host system to lose access to the USB device while the VM is running!
This is my favourite container. You can supply an existing disk image as a Docker command line argument.
-
Pull images out using
sudo find /var/lib/docker -name mac_hdd_ng.img -size +10G -
Supply your own local image with the command argument
-v "${PWD}/mac_hdd_ng.img:/image"and usesickcodes/docker-osx:nakedwhen instructing Docker to create your container.-
Naked image is for booting any existing .img file, e.g in the current working directory (
$PWD) -
By default, this image has a variable called
NOPICKERwhich is"true". This skips the disk selection menu. Use-e NOPICKER=falseor any other string than the wordtrueto enter the boot menu.This lets you use other disks instead of skipping the boot menu, e.g. recovery disk or disk utility.

# Boots in a minute or two!
There's a myriad of other potential use cases that can work perfectly with Docker-OSX, some of which you'll see below!
For a headless container, remove the following two lines from your docker run command:
# -v /tmp/.X11-unix:/tmp/.X11-unix \
# -e "DISPLAY=${DISPLAY:-:0.0}" \
This is particularly helpful for CI/CD pipelines.
# run your own image headless + SSH
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
-v "${PWD}/mac_hdd_ng.img:/image" \
sickcodes/docker-osx:nakedMust change -it to -i to be able to interact with the QEMU console
To exit a container using -i you must docker kill <containerid>. For example, to kill everything, docker ps | xargs docker kill.
Native QEMU VNC example
docker run -i \
--device /dev/kvm \
-p 50922:10022 \
-p 5999:5999 \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \
-e EXTRA="-display none -vnc 0.0.0.0:99,password=on" \
sickcodes/docker-osx:big-sur
# type `change vnc password myvncusername` into the docker terminal and set a password
# connect to localhost:5999 using VNC
# qemu 6 seems to require a username for vnc nowNOT TLS/HTTPS Encrypted at all!
Or ssh -N [email protected] -L 5999:127.0.0.1:5999, where 1.1.1.1 is your remote server IP.
(Note: if you close port 5999 and use the SSH tunnel, this becomes secure.)
Add the following line:
-e EXTRA="-display none -vnc 0.0.0.0:99,password=on"
In the Docker terminal, press enter until you see (qemu).
Type change vnc password someusername
Enter a password for your new vnc username^.
You also need the container IP: docker inspect <containerid> | jq -r '.[0].NetworkSettings.IPAddress'
Or ip n will usually show the container IP first.
Now VNC connects using the Docker container IP, for example 172.17.0.2:5999
Remote VNC over SSH: ssh -N [email protected] -L 5999:172.17.0.2:5999, where 1.1.1.1 is your remote server IP and 172.17.0.2 is your LAN container IP.
Now you can direct connect VNC to any container built with this command!
Optionally, you can enable the SPICE protocol, which allows use of remote-viewer to access your OSX container rather than VNC.
Note: -disable-ticketing will allow unauthenticated access to the VM. See the spice manual for help setting up authenticated access ("Ticketing").

echo $DISPLAYThat way, ${DISPLAY:-:0.0} will use whatever variable your X11 server has set for you, else :0.0
-v is a Docker command-line option that lets you pass a volume to the container.
The directory that we are letting the Docker container use is a X server display socket.
/tmp/.X11-unix
If we let the Docker container use the same display socket as our own environment, then any applications you run inside the Docker container will show up on your screen too! https://www.x.org/archive/X11R6.8.0/doc/RELNOTES5.html
You may when initialising or booting into a container see errors from the (qemu) console of the following form:
ALSA lib blahblahblah: (function name) returned error: no such file or directory. These are more or less expected. As long as you are able to boot into the container and everything is working, no reason to worry about these.
