Environment setup

IMPORTANT: These instructions are meant for advanced users and are not necessary for the basic get-started guide. These dependencies will be needed for installing containers and building Pantavisor. They are prepared for any apt based system such as Ubuntu, but can be adapted for your favorite distro.

The following packages are needed for building: curl, squashfs, git, docker and repo

Installing dependencies

Every package except repo is available in apt and can be installed with the following commands:

sudo apt update
sudo apt install curl squashfs git docker.io

For docker, you can follow the alternative instructions released by docker team for various Linux Distributions here: https://docs.docker.com/engine/install/

We use the repo tool used by Android project to maintain our source distribution for pantavisor.

To install repo:

mkdir -p ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
export PATH=$PATH:~/bin

If you run into any problem with repo installation, further documentation can be found in the Android Project.

Setting up dependencies

Some dependencies require further setup.

git setup

Before you use git, remember to configure your name and email globally:

git config --global user.name "Your Name"
git config --global user.email "your@email.tld"

docker setup

After installing docker, you need to grant rights to your non-root user, so you can run all of docker's commands without sudo. To do so, you can execute the following commands. Make sure to log out and log back in to activate the new group rules.

sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

Now check that you can actually use docker echo container using your normal user:

docker run hello-world

Expected output of that command should be similar to:

docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
1b930d010525: Pull complete 
Digest: sha256:41a65640635299bab090f783209c1e3a3f11934cf7756b09cb2f1e02147c6ed8
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
