#container

6 posts6 participants0 posts today

Is there any standard or existing solution for updating #container deployments offline? I'm well aware of docker image save|load, but there's no signature validation or metadata (beyond image tag, labels, etc. included in the image itself). I'm looking for a bundle format to put on a USB disk or similar, possibly holding multiple images. ​:neocat_book:

When starting a Docker #container, this uses a so-called "#Docker Image" in the background. These images can be built on top of each other (called layers).

An image can be created from yet another image, potentially resulting in many many layers.

To extract files and directories from all these layers, there's some patience and wizardry needed.

Or you use our #HowTo which shows a really nice helper script doing all the work for you. 👇

Container technology as a service, hosted on a Swiss infrastructure – that's the legendary Nine Kubernetes Engine. 💻🇨🇭 The Kubernetes clusters we manage include a fully managed software stack that offers everything you need to run your applications in production successfully. ✅ See our Kubernetes offerings for yourself on our website: nine.ch/products/kubernetes/ – so that in the future, you can spend more time on your applications again. 👈 #nke #kubernetes #managed #container #cluster #nine

I haven't had the need 'til now, but #TIL that you can store #container images in a file and load the image from the file later. Very useful for workshops and disconnected computers:
```
docker save -o /Volumes/MyUSB/oracle-db23ai-free.image.tar container-registry.oracle.com/database/free:latest
docker load -i /Volumes/MyUSB/oracle-db23ai-free.image.tar
```

Wrote a little parser for meshcore packets tonight. It's still messy and a lot more to implement. But, it reads the container format so I'm happy for now.

I have meshcore packets flowing from multiple repeaters(on different frequencies) talking on wifi using udp broadcasts.

The repeaters automatically discover each other on the network and now I'm able to watch their chatter with a quick nodejs server.
