[SOLVED] Pull Docker Image - a.w.d.m. - July-8th-2019

When I try to pull any docker image, the only thing that happens is the name of the image and the registry disappear and nothing gets pulled.

Hi there,

did you setup the system time on netPI like shown in this video: https://www.youtube.com/watch?v=CB6bYfMbFhA

Thx
Armin

I set up the time and now I can pull public images from docker hub, but when I try to pull from my companies private azure registry it still doesn't work.


RE: Pull Docker Image - Armin@netPI - July-8th-2019

Two things need to be said

1.) While Docker Hub is a site that is officially certified by an official notified CA body (https://en.wikipedia.org/wiki/Certificate_authority), your local/private repository isn't and then Docker running on netPI denies a https pull from this "trusted" registry until its certificate is loaded onto netPI additionally.
What is necessary to allow also pulls from any own repository is to load the certificate from your repository onto your netPI. For that use the Control Panel tile on netPI's landing page and in there the option "Secutiry/Public Key Infrastructure" to upload your *.pem certificate file.

2.) In the Docker web GUI you have to use the menu option "Registry" and define your custom registry in terms of IP address and symbolik name. Doing so requires at least netPI's software version 1.1.5.0 running. If the registry was setup right, if you now add a container you can now select in a drop down box you want to pull from Docker Hub or your registry.

Thx

Under Scurity I only have the option SSL/TLS Certificate.


RE: Pull Docker Image - Armin@netPI - July-8th-2019

Your netPI needs an update as I described it before. At least software version 1.1.5.0 is needed. The latest version available is 1.1.6.0

Here is how it looks like:

How do I update? I can neither find a button nor documentation.


RE: Pull Docker Image - Armin@netPI - July-8th-2019

Using the search option in the forum here with the words "firmware update" might help you.
