This is so damn cool. Relatively secure docker in docker with very an isolated docker daemon context and low overhead. A great alternative to MicroVM's like #Firecracker.

I love the presentation style too. I followed along in my terminal and everything worked. So much more helpful for me than "go to this website to learn more".

DockerDocker-in-Docker: Containerized CI Workflows | DockerDocker-in-Docker (DinD) is a technique to run Docker containers inside another Docker container. DinD makes it easy to create an isolated environment for each application or service under test in a CI platform. Learn the basics of DinD, its benefits, and use cases in this presentation.

@fyw321 @geerlingguy My 8 node cluster costs around 55W via POE. It is 3 pi4 8G control+worker nodes, and 5 pi4 4G worker-only nodes (1 is actually 8G.)

Storage is on spinning rust on , but you can do all this on local disks.

It handles a LOT:
- , , , various scrapers
-
- (another adblocking )
-
- , Prowlarr, *arr, Deluge
- Home automation helpers ( instances, /#zwave 2mqtt, but not HA itself)
- for builds (deprecated in favor of the x64 cloud lab. Building x64 docker containers on arm is BAD)
- Democratic CSI for iscsi/nfs
- container registry & cache
- recipe manager
- contact manager
- relay to gmail
- console (bootstrapping becomes a chicken and egg problem though, if it goes down wrong)
- server
-
- and a sidecar
- SSL termination for most of the rest of the network

The one with the headscarf 🧕

It's just that the test setup is cursed:

The tests run on #GitLab runners using the #Docker executor in privileged mode. This enables us to start a #KVM based #AVD for Android tests and to deploy all individual homeserver implementations using #DinD.

In order to get better debugging information, the headless virtual screen is recorded via #VNC in order to record all ongoing tests for later use.

Some people told us they don't like our tests.
