# Run Docker-OSX
```bash
docker pull sickcodes/docker-osx:latest
docker run \
--device /dev/kvm \
--device /dev/snd \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \
sickcodes/docker-osx:latest
# press ctrl G if your mouse gets stuck
# scroll down to troubleshooting if you have problems
# need more RAM and SSH on localhost -p 50922?
```
# Run but allow SSH into OSX!
```bash
docker run \
--device /dev/kvm \
--device /dev/snd \
-e RAM=4 \
-p 50922:10022 \
-v /tmp/.X11-unix:/tmp/.X11-unix \

# turn on SSH after you've installed OSX in the "Sharing" settings.
ssh fullname@localhost -p 50922
```
# Autoboot into OSX after you've installed everything
```bash
# find you containerID
docker ps
# move the no picker script on top of the Launch script
# NEW CONTAINERS
docker exec containerID mv ./Launch-nopicker.sh ./Launch.sh
# LEGACY CONTAINERS
docker exec containerID bash -c "grep -v InstallMedia ./Launch.sh > ./Launch-nopicker.sh
chmod +x ./Launch-nopicker.sh

# Requirements: KVM on the host
Need to turn on hardware virtualization in your BIOS, very easy to do.
Then have QEMU on the host if you haven't already
```bash
# 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
# CENTOS RHEL FEDORA
sudo yum install libvirt qemu-kvm
# then run
sudo systemctl enable libvirtd.service
sudo systemctl enable virtlogd.service
sudo modprobe kvm
# reboot
```
# Start the same container later (persistent disk)
This is for when you want to run the SAME container again later.
If you don't run this you will have a new image every time.
```bash
# look at your recent containers and copy the CONTAINER ID
docker ps --all
# docker start the container ID
docker start 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"
```
# Additional Boot Instructions
- Boot the macOS Base System
- 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`
## Creating images:
```bash
# You can create an image of an already configured and setup container.
# This allows you to effectively duplicate a system.
# To do this, run the following commands
# make note of your container id
docker ps --all
docker commit containerid newImageName
# To run this image do the following
docker run \
--device /dev/kvm \
--device /dev/snd \
-v /tmp/.X11-unix:/tmp/.X11-unix \
newImageName
```
# Troubleshooting
libgtk permissions denied error, thanks @raoulh + @arsham
```bash
echo $DISPLAY
# ARCH
sudo pacman -S xorg-xhost
# UBUNTU DEBIAN
sudo apt install x11-xserver-utils
# CENTOS RHEL FEDORA
sudo yum install xorg-x11-server-utils
# then run
xhost +
```
PulseAudio for sound (note neither [AppleALC](https://github.com/acidanthera/AppleALC) and varying [`alcid`](https://dortania.github.io/OpenCore-Post-Install/universal/audio.html) or [VoodooHDA-OC](https://github.com/chris1111/VoodooHDA-OC) have [codec support](https://osy.gitbook.io/hac-mini-guide/details/hda-fix#hda-codec) though [IORegistryExplorer](https://github.com/vulgo/IORegistryExplorer) does show the controller component working):
```bash
docker run \
--device /dev/kvm \
-e AUDIO_DRIVER=pa,server=unix:/tmp/pulseaudio.socket \
-v "/run/user/$(id -u)/pulse/native:/tmp/pulseaudio.socket" \
-v /tmp/.X11-unix:/tmp/.X11-unix \
sickcodes/docker-osx
```
PulseAudio debugging:
```bash
docker run \
--device /dev/kvm \
-e AUDIO_DRIVER=pa,server=unix:/tmp/pulseaudio.socket \
-v "/run/user/$(id -u)/pulse/native:/tmp/pulseaudio.socket" \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e PULSE_SERVER=unix:/tmp/pulseaudio.socket \
sickcodes/docker-osx pactl list
```
Alternative run, thanks @roryrjb
```bash
docker run \
--privileged \
--net host \
--cap-add=ALL \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-v /dev:/dev \
-v /lib/modules:/lib/modules \

Check if your hardware virt is on
```bash
egrep -c '(svm|vmx)' /proc/cpuinfo
```
Try adding yourself to the docker group
```bash
sudo usermod -aG docker "${USER}"
```
Turn on docker daemon
```bash
# run ad hoc
sudo dockerd
# or daemonize it
sudo nohup dockerd &
# or enable it in systemd
sudo systemctl enable docker
```
# How to Enable Network Forwarding
Allow ipv4 forwarding for bridged networking connections:
This is not required for LOCAL installations and may cause containers behind [VPN's to leak host IP](https://sick.codes/cve-2020-15590/).
If you are connecting to a REMOTE Docker-OSX, e.g. a "Mac Mini" in a datacenter, then this may boost networking:
```bash
# enable for current session
sudo sysctl -w net.ipv4.ip_forward=1
# OR
# sudo tee /proc/sys/net/ipv4/ip_forward <<< 1
# enable permanently
sudo touch /etc/sysctl.conf
sudo tee -a /etc/sysctl.conf <<EOF
net.ipv4.ip_forward = 1
EOF
# OR edit manually
nano /etc/sysctl.conf || vi /etc/sysctl.conf || vim /etc/sysctl.conf
# now reboot
```
# How to install Docker if you don't have Docker already
```bash
### Arch
sudo pacman -S docker
sudo groupadd docker
sudo usermod -aG docker "${USER}"
### Ubuntu
sudo apt remove docker docker-engine docker.io containerd runc -y
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -y
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update -y
sudo apt install docker-ce docker-ce-cli containerd.io -y
sudo groupadd docker
sudo usermod -aG docker "${USER}"
```
### Fedora: if you have no internet connectivity from the VM, and you are using bridge networking:
```bash
# Set the docker0 bridge to the trusted zone
sudo firewall-cmd --permanent --zone=trusted --add-interface=docker0
sudo firewall-cmd --reload
```
# Backup the disk (Where's my disk?)
You can use `docker cp`
```bash
# docker copy your image OUT of your container (warning, double disk space)
docker cp oldcontainerid:/home/arch/OSX-KVM/mac_hdd_ng.img .
```
Or if you lost your container, find it with this:
```bash
# fast way
sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img
# you can move (mv) it somewhere
sudo mv somedir/mac_hdd_ng.img .
# start a new container
# get the new container id
docker ps
# docker cp INTO new container
docker cp ./mac_hdd_ng.img newcontainerid:/home/arch/OSX-KVM/mac_hdd_ng.img
```
# DESTROY: Wipe old images
This is useful for getting disk space back.
It will delete your old (and new) docker containers.
```bash
# WARNING deletes all old images, but saves disk space if you make too many containers
# The following command will make your containers RIP
docker system prune --all
docker image prune --all
```
# INSTANT OSX-KVM in a BOX!
This Dockerfile automates the installation of OSX-KVM inside a docker container.
It will build a Catalina Disk with up to 200GB of space.
You can change the size and version using build arguments (see below).
This file builds on top of the work done by Dhiru Kholia and many others on the OSX-KVM project.
# Custom Build
```bash
docker build -t docker-osx:latest \
--build-arg VERSION=10.14.6 \
--build-arg SIZE=200G
```
```bash
docker run \
-e RAM=4 \
-e SMP=4 \
-e CORES=4 \
-e EXTRA='-usb -device usb-host,hostbus=1,hostaddr=8' \
-e INTERNAL_SSH_PORT=23 \
--device /dev/kvm --device /dev/snd -v /tmp/.X11-unix:/tmp/.X11-unix docker-osx:latest
```
## What is `${DISPLAY:-:0.0}`?
`$DISPLAY` is the shell variable that refers to your X11 display server.
`${DISPLAY}` is the same, but allows you to join variables like this:
- e.g. `${DISPLAY}_${DISPLAY}` would print `:0.0_:0.0`
- e.g. `$DISPLAY_$DISPLAY` would print `:0.0`
...because `$DISPLAY_` is not `$DISPLAY`
`${variable:-fallback}` allows you to set a "fallback" variable to be substituted if `$variable` is not set.
You can also use `${variable:=fallback}` to set that variable (in your current terminal).
In Docker-OSX, we assume, `:0.0` is your default `$DISPLAY` variable.
You can see what yours is
```bash
echo $DISPLAY
```
Hence, `${DISPLAY:-:0.0}` will use whatever variable your X11 server has set for you, else `:0.0`
## Todo:

- GPU Acceleration (Hackintosh? Passthru bus id of cards? AMD Vega? Nvidia-SMI?)
- Virt-manager
