Post: Poor Man's On-Premise Backups of a Kubernetes Cluster

[jofas]

• [x] Fix mounting of /dev/sdb1 (no mount point defined)
• [x] Parent image with self-built admin cli tools installed
• [x] Try out docker run --dns $DNS instead of setting the dns from inside the Dockerfile
• [x] Replace ssmtp with a simple python script (just because I'm more familiar with it and find ssmtp a little clunky)
• [x] Don't compile config files into the image but mount them via volume at runtime
• [x] Move everything from Dockerfile to backup.sh (no need for supervisord anymore)
• [x] DNS settings inside backup.sh (DNS from env file) instead of --dns to keep config in two places

• [x] env file in config volume as well and source it in backup script

• [x] Diagram
• [x] Dark version of Diagram
• [ ] Write the thing
