## Technical details
**Current large image size:** 17.5GB
The images (excluding `:naked`) launch a container with an existing installation with a couple of premade configurations. This special image was developed by [Sick.Codes](https://sick.codes):
- username: `user`, password: `alpine`
- ssh enabled (`localhost:50922`)
- vnc enabled (`localhost:8888`)
- auto-updates disabled
- serial number generators!
- x11 forwarding is enabled
- runs on top of QEMU + KVM
- supports big sur, custom images, xfvb headless mode
- you can clone your container with `docker commit`
### Requirements
- at least 50 GBs (half for the base image, half for your runtime image
- virtualization should be enabled in your bios settings
- a kvm-capable host
### To be done
- documentation for security researchers
- gpu acceleration
- support for virt-manager
## Docker
Images built on top of the contents of this repository are also available on **Docker Hub** for convenience: https://hub.docker.com/r/sickcodes/docker-osx
A comprehensive list of the available Docker images and their intended purpose can be found in the [Instructions](README.md#Instructions)

#### Further examples
**Current large image size:** 17.5GB
Apart from the previous examples, there's a myriad of other potential use cases that can work perfectly with Docker-OSX.
The images (excluding `:naked`) launch a container with an existing installation with a couple of premade configurations. This special image was developed by [Sick.Codes](https://sick.codes):
- SSH enabled
- username is `user`
- password is `alpine`
- auto-updates are disabled
## Requirements
You will need around *50 GB* of space to run this image: half for the base image + half for your runtime image.
If you run out of space, you can delete all your old Docker images/history/cache by simply deleting `/var/lib/docker`, and restarting `dockerd`.

# How to Enable Network Forwarding
### Enable IPv4 forwarding for bridged network connections

### I'd like to use SPICE instead of VNC
This is useful for getting disk space back.
Optionally, you can enable the SPICE protocol, which allows you to use `remote-viewer` to access it rather than VNC.
It will delete ALL your old (and new) docker containers.
Note: `-disable-ticketing` will allow unauthenticated access to the VM. See the [spice manual](https://www.spice-space.org/spice-user-manual.html) for help setting up authenticated access ("Ticketing").

Then simply do `remote-viewer spice://localhost:3001` and add `--spice-debug` for debugging.
### CI/CD Related Improvements
#### Tips for reducing the size of the image
- 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.img` to fix any errors.
* Run `qemu-img convert -O qcow2 mac_hdd_ng.img deduped.img` and check for errors again
* OPTIONAL: Run `qemu-img convert -c -O qcow2 deduped.img compressed.img` to 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
