[mesh-dev] Salt, Docker, generator images

Hi! Just wanting to share some new stuff we have been using in wlan slovenija network. So for managing our servers, we started using Salt and Docker. You can find our Salt configurations here: https://github.com/wlanslovenija/servers-salt-states https://github.com/tozd/salt We are putting all stuff into Docker images. Like nodewatcher, routing, etc. https://github.com/wlanslovenija/docker-router-olsrd And interesting thing we started doing is putting OpenWrt firmware generators for each platform into its own Docker image: https://github.com/wlanslovenija/firmware-core In this way it is easy to share already compiled firmware generators. People do not have to compile them themselves. You can then simply SSH into it and compile images for that platform. (We use nodewatcher to connect to them and compile based on the set of packages our users want and with configuration baked in into the image itself.) For gateways and VPN servers, we are simply using (or planing to use) OpenWrt images generated by nodewatcher. :-) For x86 platform and it works. In this way it is easy to reuse the existing stack. The servers above are mostly for website, nodewatcher itself, etc. We have also quite few OpenWrt packages: https://github.com/wlanslovenija/firmware-packages-opkg So for OpenWrt we are trying to put everything into packages. For servers into Docker images. For configuring the network stack for Docker we are using: https://github.com/wlanslovenija/netcfg Some random apps we created: https://github.com/wlanslovenija/wireless-info https://github.com/wlanslovenija/netmeasured I am sharing all this stuff so that others see if there is anything interesting so that we do not duplicate too much things. Or that we might use the same patterns/tools to be easier to reuse. Like Salt, Docker. The most interesting for me is that if we would agree upon a simple format for generator images, it would be a great way to share firmware builders one can simply plug into their own systems. We all use OpenWrt based stuff, this is then just to make module around it so that I can ship to somebody a firmware they are not used to, but they can still generate it with tools they are used to.
