### Big Sur [](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
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):
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

### Already set up or just looking to make a container quickly? Check out our [container creation examples](https://github.com/sickcodes/Docker-OSX#container-creation-examples) section.
There are several different Docker images available, which are suitable for different purposes.
-`sickcodes/docker-osx:latest` - [I just want to try it out.](https://github.com/sickcodes/Docker-OSX#quick-start-large-pre-made-image)
-`sickcodes/docker-osx:latest` - [I want to use Docker-OSX to develop/secure apps in Xcode (sign into Xcode, Transporter)](https://github.com/sickcodes/Docker-OSX#basic-quick-start-docker-osx)
-`sickcodes/docker-osx:naked` - [I want to use Docker-OSX for CI/CD-related purposes (sign into Xcode, Transporter)](https://github.com/sickcodes/Docker-OSX#fully-headless-using-my-own-image-for-cicd)
Create your personal image using `:latest`. Then, extract the image. Afterwards, you will be able to duplicate that image and import it to the `:naked` container, in order to revert the container to a previous state repeatedly.
-`sickcodes/docker-osx:auto` - [I'm only interested in using the command line. (Useful for compiling software or using Homebrew headlessly).](https://github.com/sickcodes/Docker-OSX#pre-built-image-arbitrary-command-line-arguments)
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.
- (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.)

More specific/advanced troubleshooting questions and answers may be found in [More Questions and Answers](https://github.com/sickcodes/Docker-OSX#more-questions-and-answers). You should also check out the [closed issues](https://github.com/sickcodes/Docker-OSX/issues?q=is%3Aissue+is%3Aclosed). Someone else might have gotten a question like yours answered already even if you can't find it in this document!
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](https://www.x.org/archive/X11R6.8.0/doc/RELNOTES5.html)
1. You can now 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 above.
2. This is for when you want to run the SAME container again later.
[Extract the .img file](https://github.com/sickcodes/Docker-OSX#backup-the-disk-wheres-my-disk), and then use that [.img file with :naked](https://github.com/sickcodes/Docker-OSX#quick-start-own-image-naked-container-image)
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](https://github.com/sickcodes/Docker-OSX#initial-setup) section and the [routine checks](https://github.com/sickcodes/Docker-OSX#routine-checks) section as you may have missed a setup step or may not have all the needed Docker dependencies ready to go.
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`.
For example (below) the `buff/cache` already contains 20 Gigabytes of allocated RAM:
Note: [AppleALC](https://github.com/acidanthera/AppleALC), [`alcid`](https://dortania.github.io/OpenCore-Post-Install/universal/audio.html) and [VoodooHDA-OC](https://github.com/chris1111/VoodooHDA-OC) do not have [codec support](https://osy.gitbook.io/hac-mini-guide/details/hda-fix#hda-codec). However, [IORegistryExplorer](https://github.com/vulgo/IORegistryExplorer) does show the controller component working.
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:
Fedora's default firewall settings may prevent Docker's network interface from reaching the internet. In order to reoslve this, you will need to whitelist the interface in your firewall:
- 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
First make sure [autoboot is enabled](#autoboot-into-osx-after-youve-installed-everything)
Next, you will want to set up SSH to be automatically started.
```bash
sudo systemsetup -setremotelogin on
```
Make sure to commit the new docker image and save it, or rebuild as described in the [section on reducing disk space](#how-to-reduce-the-size-of-the-image).
Then run it with these arguments.
```bash
# Run with the -nographic flag, and enable a telnet interface
Inside the `./custom` folder you will find `4` scripts.
-`config-nopicker-custom.plist`
-`opencore-image-ng.sh`
These two files are from OSX-KVM.
You don't need to touch these two files.
The config.plist has 5 values replaced with placeholders. [Click here to see those values for no reason.](https://github.com/sickcodes/Docker-OSX/blob/master/custom/config-nopicker-custom.plist#L705)
-`generate-unique-machine-values.sh`
This script will generate serial numbers, with Mac Addresses, plus output to CSV/TSV, plus make a `bootdisk image`.
You can create hundreds, `./custom/generate-unique-machine-values.sh --help`
```bash
./custom/generate-unique-machine-values.sh \
--count 1 \
--tsv ./serial.tsv \
--bootdisks \
--output-bootdisk OpenCore.qcow2 \
--output-env source.env.sh
```
Or if you have some specific serial numbers...
-`generate-specific-bootdisk.sh`
```bash
generate-specific-bootdisk.sh \
--model "${DEVICE_MODEL}" \
--serial "${SERIAL}" \
--board-serial "${BOARD_SERIAL}" \
--uuid "${UUID}" \
--mac-address "${MAC_ADDRESS}" \
--output-bootdisk OpenCore-nopicker.qcow2
```
#### This example generates a random set of serial numbers at runtime, headlessly
- Supply your own local image with the command argument `-v "${PWD}/mac_hdd_ng.img:/image"` and use `sickcodes/docker-osx:naked` when instructing Docker to create your container.
- Naked image is for booting any existing .img file, e.g in the current working directory (`$PWD`)
- By default, this image has a variable called `NOPICKER` which is `"true"`. This skips the disk selection menu. Use `-e NOPICKER=false` or any other string than the word `true` to enter the boot menu.
# run local copy of the auto image + SSH + Boot menu
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
-v "${PWD}/mac_hdd_ng_auto.img:/image" \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \
-e "NOPICKER=false" \
sickcodes/docker-osx:naked
```
### Building an OSX container with video output
The Quick Start command should work out of the box, provided that you keep the following lines. Works in `auto`&`naked` machines:
```
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \
```
#### Download the image manually and use it in Docker [](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
#### Use a prebuilt image with arbitrary command line arguments [](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
There's a myriad of other potential use cases that can work perfectly with Docker-OSX, some of which you'll see below!
### Building a headless OSX container
For a headless container, **remove** the following two lines from your `docker run` command:
```
# -v /tmp/.X11-unix:/tmp/.X11-unix \
# -e "DISPLAY=${DISPLAY:-:0.0}" \
```
#### Building a headless container from a custom image [](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
This is particularly helpful for CI/CD pipelines.
```bash
# run your own image headless + SSH
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
-v "${PWD}/mac_hdd_ng.img:/image" \
sickcodes/docker-osx:naked
```
### Building a headless container which allows insecure VNC on localhost (!for local use only!)
**Must 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`.**
In the Docker terminal, press `enter` until you see `(qemu)`.
Type `change vnc password`
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 connect using the Docker container IP, for example `172.17.0.2:5999`
Remote VNC over SSH: `ssh -N root@1.1.1.1 -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!
### I'd like to use SPICE instead of VNC
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](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.
#### Creating images based on an already configured and set up container
```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
```
#### Run Catalina Pre-Installed [](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
```bash
docker pull sickcodes/docker-osx:auto
# boot directly into a real OS X shell with a visual display [NOT HEADLESS]
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \
sickcodes/docker-osx:auto
# username is user
# passsword is alpine
```
```bash
docker pull sickcodes/docker-osx:auto
# boot directly into a real OS X shell with no display (Xvfb) [HEADLESS]
docker run -it \
--device /dev/kvm \
-p 50922:10022 \
sickcodes/docker-osx:auto
# username is user
# passsword is alpine
# Wait 2-3 minutes until you drop into the shell.
```
#### Run the original version of Docker-OSX
```bash
docker pull sickcodes/docker-osx:latest
docker run -it \
--device /dev/kvm \
--device /dev/snd \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${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 enable SSH in OS X (Original Version)!
```bash
docker run -it \
--device /dev/kvm \
--device /dev/snd \
-p 50922:10022 \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-e "DISPLAY=${DISPLAY:-:0.0}" \
sickcodes/docker-osx:latest
# turn on SSH after you've installed OS X in the "Sharing" settings.
ssh user@localhost -p 50922
```
#### Autoboot into OS X after you've installed everything
Add the extra option `-e NOPICKER=true`.
Old machines:
```bash
# find your containerID
docker ps
# move the no picker script on top of the Launch script
