# Features In Docker-OSX v2.5
- CI/CD weaponization thru vnc and xdotool
- OSX-KVM
- X11 Forwarding
- SSH on localhost:50922 
- QEMU
- VNC on localhost:8888 [vnc version is inside a separate directory](https://github.com/sickcodes/Docker-OSX/blob/master/vnc-version/Dockerfile)

Pull requests, suggestions very welcome!

```bash

docker pull sickcodes/docker-osx

docker run --privileged -e "DISPLAY=${DISPLAY:-:0.0}" -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osx

# press ctrl G if your mouse gets stuck

# scroll down to troubleshooting if you have problems

# need more RAM and SSH on 0.0.0.0:50922?

docker run -e RAM=4 -p 50922:10022 --privileged -e "DISPLAY=${DISPLAY:-:0.0}" -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osx:latest

ssh fullname@localhost -p 50922

# 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 -y

# 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 your system 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"

```

# Additional Boot Instructions

- Boot the macOS Base System

- Click Disk Utility

- Erase the BIGGEST disk (around 200gb default), DO NOT MODIFY THE SMALLER DISKS.

- Click Reinstall macOS



## Creating images:
```bash
# You can create an image of a already configured and setup container. This allows you to effectively duplicate a system.
# To do this, run the following commands

docker ps --all #make note of your container id
docker commit containerID newImageName

# To run this image do the following
docker run --privileged -e "DISPLAY=${DISPLAY:-:0.0}" -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 +

docker run --privileged -e "DISPLAY=${DISPLAY:-:0.0}" -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osx ./OpenCore-Boot.sh
```

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 sickcodes/docker-osx
```

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
sudo dockerd
# or daemonize it
sudo nohup dockerd &
```

Check /dev/kvm permissions

```bash
sudo chmod 666 /dev/kvm
```

If you don't have Docker already

```bash
### Arch (pacman version isn't right at time of writing)

wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.5.tgz
tar -xzvf docker-19.03.5.tgz
sudo cp docker/* /usr/bin/
sudo groupadd docker
sudo usermod -aG docker "${USER}"

### Ubuntu

apt-get remove docker docker-engine docker.io containerd runc -y
apt-get 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
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
apt-get update -y
apt-get install docker-ce docker-ce-cli containerd.io -y
sudo groupadd docker
sudo usermod -aG docker "${USER}"


```

If you have no internet connectivity from the VM, you are using bridge
networking, and you are running Fedora:

```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

```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 \
--privileged -v /tmp/.X11-unix:/tmp/.X11-unix docker-osx:latest

```

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

```
