Summary of Behaviour:

A.   OpenJDK 7 b65.  

1.   Default in java.security is securerandom.source=/dev/urandom   
2.   If securerandom.source=/dev/urandom, NativePRNG is used, SecureRandom.nextBytes() is non-blocking via /dev/urandom ; SecureRandom.generateSeed(x) is blocking via /dev/random
3.   if securerandom.source=/dev/random, then SHA1PRNG is used.  Initial seed is blocking via /dev/random.   No other accesses.
4.   If securerandom.source=/dev/./urandom then SHA1PRNG is used.  Initial seed is non-blocking via /dev/./urandom.  No other accesses.

B.   Oracle JDK 8 b25.

Persistent data storage on CoreOS-cluster

Storing the data on the host machine

Data directories are created in /home/coreos and mounted into the container using volume cli options of docker run. All data the container writes is stored on the host and as long as the host persists safe against container restarts / recreates.

• Pro
  • No effort, just create the directories and mount them into the container
• Contra
• Container is bound to host (unable to failover)
