docker swarm upgrade
View swarm-upgrade.md

Replace your Swarm Manager and Workers with updated versions of docker

  • it's best to replace nodes, don't do apt/yum upgrades.
  • both would work, but VM replacment forces me to think of it as immutable and prevents making pets
  • if you don't want to update join scripts for manager IP's, then do something like Elastic IP's so manager IP's won't change.

Lets assume you have 3 managers and 3 workers on 17.06 and you want to update to 17.12

  • managers: m1, m2, m3

ffmpeg youtube live event rtmp stream from raspberry pi with raspi camera (raspivid)
View readme.md
  1. compile ffmpeg for arm https://github.com/fiorix/ffmpeg-arm
  2. create youtube 'live event'. get rtmp url + session id
  3. run this:
raspivid -o - -t 0 -vf -hf -fps 30 -b 6000000 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i - -vcodec copy -acodec aac -ab 128k -g 50 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/<SESSION>

you can tweak -b and -fps to your liking. the settings above work well for 1080p. by not specifying width or height we get the full 1920x1080 resolution from the raspi camera
