Unable to run Docker inside Docker-OSX

[rationalthinker1]

Hello,
I want to install Docker to get it test some build process. However, I get this error. Docker requires a processor with virtualization capabilities and hypervisor support.

I used to do it before in vmware. Linux -> windows 10 -> Linux

Use the sysctl kern.hv_support (output 1 is good) command to check if Hypervisor is enabled within the macOS VM.

If Hypervisor is not enabled, check that you have the required CPU features. Run the sysctl -a | grep machdep.cpu.features command and look for the presence of VMX flag.

How do I add the vmx flag? How do i do the following:

Make sure that kvm_intel module is loaded properly. This is documented in our main documentation.

Make sure the VM is booted with VMX support passed through using one of the two below strategies:

You may add vmx,rdtscp arguments to the -cpu option in boot-macOS.sh file (easier option).

You may add +vmx, to the front of MY_OPTIONS in the boot script while changing -cpu Penryn to -cpu Skylake-Client or any other suitable supported CPU.

Note: Host CPU passthrough is troublesome and not generally recommended.

Just wanted to give an update. I did get it to work.
I did the following

• I cloned this project
• found all references in dockerfiles to Penryn to changed to max.
• Added +vmx flag in helm.values. Also changed Penryn to max in helm.values

Ran docker build -t docker-osx -f Dockerfile.naked -t docker-osx-custom . in the project folder.

Ran this to start docker-osx

docker run -it \
 --device /dev/kvm \
 -p 50922:10022 \
 -p 24800:24800 \
 -p 222:22 \
 -v "${PWD}/mac_hdd_ng.img:/image" \
 -v /tmp/.X11-unix:/tmp/.X11-unix \
 -e "DISPLAY=${DISPLAY:-:0.0}" \
 -e "NOPICKER=false" \
 -e "RAM=8" \
 -v "/home/raza:/mnt/hostshare" \
 -e EXTRA="-virtfs local,path=/mnt/hostshare,mount_tag=hostshare,security_model=passthrough,id=hostshare" \
 docker-osx-custom

Thanks @rationalthinker1 . I am trying out on the same stuff now! Will @sickcodes merge the change if it works? Or I have to follow @rationalthinker1 's guide and build my custom image?

Looks good to me, I think it's time to merge the max. Will try and test all the images over the weekend.

Need to test this on all 4 first:
