docker
I struggled for some time getting postgres to run on docker/k8s with /var/lib/postgresql/data mounted on an nfs-server. I reguallary ended up with chown: changing ownership of '/var/lib/postgresql/data/base/**/**': Operation not permitted. I'm no expert in nfs and its export-options

Atm I'm fiddling around with my raspberry pi,orange pi,odroid-Kubernetes,Docker,Ceph-cluster. Here some links: * Install k8s on arm/rpi * k8s: Expose pods externally via services (manual or metacontroller)

Since I'm setting up my orange pi,rpi,odroid cluster for the n-th time I actually found a great tool the helps you do everything at the same time in different terminals. "Terminator"
ZeroMQ-based thrift "peer" that is server (multiple services) and client in one. Using one router for punshing out.

It was GlobalGamJam and I decided to give it a shot. It was very attractive since there was a jam-site in Düren where I live. Very small one organized by headup games. (Big thank to them, Mark and Dieter). Since I do need to get into Unity3d again, that was
