Solved: [ kubernetes ] client intended to send too large body

To set client_max_body_size in ingress-nginx-controller you must add more this line to yaml file like that: 

apiVersion: networking.k8s.io/v1

kind: Ingress

metadata:

  annotations:

    nginx.ingress.kubernetes.io/proxy-body-size: "20m"

.......

Note: 

1. 20m ~ 20MB and no need restart nginx pod .

2. some template yaml have added this line to annotations : ingress.kubernetes.io/proxy-body-size: "<valuem>" but it is not enough you must add this line : nginx.ingress.kubernetes.io/proxy-body-size there is nginx in the first line .

Upgrade nginx on the fly - no downtime

          #first please check pid file by:

          cat /var/run/nginx.pid  

#copy new binary to /sbin/nginx and force overwrite if you don't use option "-f" you will see this error : 

cp: cannot create regular file ‘/sbin/nginx’: Text file busy

/bin/cp -f nginx /sbin/nginx 

#spawn a new nginx master/workers set

kill -s USR2 `cat /var/run/nginx.pid`

#check process

ps aux | grep nginx

# check pid 

tail -n +1 /var/run/nginx.pid*

#shut down the old master's worker

kill -s WINCH `cat /var/run/nginx.pid.oldbin`

#check 

ps aux | grep nginx

# safely shut down the old master process

kill -s QUIT `cat /var/run/nginx.pid.oldbin`
