kubernetes pods dying

Why are my pods dying?

pods that die:
homlishWeb
jukebox
weather
pods that don't die:
hcr
prometheus & grafana
nginx

Internets seems to blame the logs. My logs seem to indicate a volume mount issue, possibly NFS?

ffmpeg to sound card

I never did figure this out. Maybe ffmpeg needs to be compiled w/ devices

ffmpeg –devices
linux:
[NULL @ 0x3171700] Unable to find a suitable output format for ‘–devices’
–devices: Invalid argument

mac:
[NULL @ 0x7ff53c810600] Unable to find a suitable output format for ‘–devices’
–devices: Invalid argument

The problem: latest java required TLS 1.2

Solution 1: edit java config to allow TLS1.1
issue: everytime we update java we would need to fix the java config

Solution 2: roll my own
failed miserably

Solution 3: install maridb to kubernetes

kmysql.homlish.net 10.11.168.244

had to connect to the pod to create users
CREATE USER ‘phomlish’@’%’ IDENTIFIED BY ‘****’;
