How does one access the hassio file system via docker from the command line?

Configuration
1

I’m using Ubuntu on a VM and am installing via

curl -sL https://raw.githubusercontent.com/home-assistant/hassio-build/master/install/hassio_install | bash -s

It installs and runs, though I’m having DNS issues that others have reported with LE and DuckDns. How can I, from the Ubuntu command line gain access to the Hassio shell? I believe there is a docker command, but I can’t figure out how to get in.

docker exec -it hass /bin/bash
that’s provided your docker is called hass, not sure what the name is for hass.io
you should be able to get the name using docker ps -a

@lolouk44 forgive me for being dense, but why do ups have two of them? Which one is correct?

CONTAINER ID        IMAGE                                    COMMAND                  CREATED             STATUS              PORTS               NAMES

I’m sorry I don’t know the answer for this one. As hass.io is an all in one solution, I can only think the 2nd container is for admin purposes (hence the name amd64-hassio-supervisor?), like maybe check for updates and install them?

the supervisor is what coordinates hassio. The other is just your home assistant docker.

You really should understand what it’s doing before randomly installing scripts from the internet.

based on this, I’m guessing your are running Ubuntu Bionic.
If so, this is a known issue with Docker & Ubuntu Bionic, which I hope someone is going to resolve, since the internet is full of it.

A quick workaround, run this on your Host machine (Ubuntu) as root user:

mkdir -p /etc/docker
echo '{"dns": ["8.8.8.8", "8.8.4.4"]}' > /etc/docker/daemon.json

Reboot and voila.

(About the reboot, there are other ways, but this is by far the quickest and easiest method).
