Docker in Vagrant Ubuntu VM

Prereqs:

virtualbox
virtualbox-extension-pack
vagrant
vagrant-vbguest

Features

Folder share

By default, docker mounts will work within $HOME/workspace folder, but feel free to adjust this to your needs.

Use vagrant reload to apply new configuration - beware this will reboot your VM with all the containers running on it

Port forwaring

If you mount any ports on docker host to container, you can reach them from actual VM host by editiling Vagrant file ports array.

Run

Clone the repo

git clone https://github.com/toshke/vagrant-ubuntu-docker.git && cd vagrant-ubuntu-docker

To create and run the VM

make provision

To connect to Docker from the host

eval $(make env) && docker info

Why?

Docker desktop application for MacOS seems to be taking 2 full cores on my mac, all of the time. It's not hyperkit issues it's actual Docker app that is having 100% cpu usage

Alternatives

Running docker via minikube as suggested by this post yielded veeery poor disk perfromance for myself. E.g. running du -h -d1 within average node_modules folders took > 10 secs. On VMBox/Ubuntu mounted option, this works with sub-second performance.

While aforemntioned post suggests against 3 layer drive mapping, this works just fine for myself, and in competition of 3 (Docker 4 desktop, Minikube, Vagrant provisioned VM) works the best.

Potential issues

VBox may complain if 192.168.56.2 ip is already reserved by another network iface on your computer. Just edit Vagrantfile#4 to apply available IP
