After a fresh install of Ubuntu server 20.04 on a Raspberry Pi (3b+ in this case) you may find that the default login (user: “ubuntu” password: “ubuntu”) won’t get you logged in.
After waiting for a few minutes while googling this the Rpi output some cloud-init and SSH-key messages. When trying again the default ubuntu/ubuntu login worked just fine.
So, it turns out that even though the login screen is shown and it looks like the OS has fully booted, it won’t be possible to log in until the cloud-init etc. have finished (which may take 5min or so)!
After having received several inquiries from people about how to get started with EdgeX Foundry I’ve decided to write a hands-on tutorial. Hopefully this will make it easier for newcomers to setup a system, configure data ingestion, data export & many other things.
Incidentally, getting started with EdgeX Foundry is also an excellent way to learn how to practically leverage new concepts and technologies in IT. In addition to learning about open source IoT solutions, the guide also covers topics like:
Building, running and monitoring containers
Grouping containers with docker-compose
Tools like Postman, cURL, etc.
The guide started as a blog post but ended up being way too long. Now it’s in PDF format and clocks in at 48 pages. Hopefully not too long for those looking to get started 🙂
