OneRT arm build

Prerequisites

Remove docker-io

If your ubuntu machine's version is 18.04 you have to remove docker-io.

sudo apt-get -y remove docker docker-engine docker.io containerd runc

Install docker-ce

If docker is not installed you have to install docker.

sudo apt-get update
sudo apt-get -y install \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
arch=$(dpkg --print-architecture)
sudo add-apt-repository \
  "deb [arch=${arch}] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \
  stable"
sudo apt-get update
sudo apt-get -y install docker-ce docker-ce-cli containerd.io

Set your ubuntu user as docker group to use docker as a non-root user

sudo groupadd docker
sudo usermod -aG docker $USER
sudo chown "$USER":"$USER" ~/.docker -R
sudo chmod g+rwx ~/.docker -R
# You have to reboot your ubuntu machine to enable non-root users to use docker.

Pull 'one-devtools' docker image

docker pull nnfw/one-devtools:bionic
