I recently stumbled across the balenaDash starter project thanks to the advertisement when I was using Etcher to create a linux mint bootable usb and decided to pull out my old Raspberry Pi 2.
I am trying to become more familiar with linux and utilizing the command prompt, but need some help following the starter project.
- Raspberry Pi 2 is flashed with balena-cloud-balenaDash-raspberry-pi2-2.26.0+rev1-dev-v8.0.0.img and is online and accessible from the balenaCloud
- Successfully logged into balena through “balena login” and web authorization on windows through balena-cli.
1. balena push balenaDash
When I “balena push balenaDash” I get the following error:
[Info] Starting build for balenaDash, user my_username_was_here
[Info] Dashboard link: https://my_device_dash_url_was_here
[Info] Building on arm01
[Info] Pulling previous images for caching purposes…
[Success] Successfully pulled cache images
[Error] Some services failed to build:
[Error] Service: main
[Error] Error: Cannot locate specified Dockerfile: Dockerfile
[Error] Not deploying release.
Remote build failed
2. LCD Screen Install
Need help installing my LCD screen, but unsure how to access sudo command.
Here are the instructions:
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
I am confused about how to use sudo commands within balenaOS, whether it’s through balena-cli or directly with a keyboard attached to my Raspberry Pi 2 and the balenaOS command prompt. Even when I go to “root”, it says that sudo is unknown. Additionally, I do not know the default password.
I realize these are beginner level issues, but I could not find any solutions when searching around.
