k8s - liveness probe failure threshold


While troubleshooting production deployment, was ask how many times does k8s hit pod before it gives up. So k8s has a failureThreshold set to 3. So, if a request to probe health 4th times then it will get timeout and deployment fails. 

For an pod that is already running but then fail liveness problem, then it falls back to the configure RestartPolicy.

As documented here.

The specified initialization vector (IV) does not match the block size for this algorithm

If you're getting  exception when trying to assigned key to a symmetric key and getting error message below :- The specified initialization vector (IV) does not match the block size for this algorithm And your code probably look like something below :- Then you need to go into debug mode and start looking into the supported size for IV as shown in diagram below :- As you can see, IV is 16 bytes, so you need to provide 16 bytes. The same goes for Key field too, if you're adding anything to it. As long as you provide a valid key size, then we're good and you're code will be ready.
