Thanks for creating this PR.
Can you please provide more information about this issue? fails where? under which circumstances?
5.5.0.3 is being used more than a year and tests completes successfully.

@roimenashe, this is what I'm getting when trying to pull 5.5.0.3:

% docker pull aerospike/aerospike-server:5.5.0.3  
5.5.0.3: Pulling from aerospike/aerospike-server
cae7303ade7f: Verifying Checksum 
aca507f16e13: Verifying Checksum 
829a4d716723: Download complete 
daeb228a2a38: Download complete 
filesystem layer verification failed for digest sha256:aca507f...

Unfortunately newer versions fail checksum validation as well. However 5.5.0.2 works like a charm.

Just to be clear, the main goal of this PR is to move bootstrap.properties to the test resources, where they belong.
Aerospike container version is the second [optional] question. I can of course leave the current one, but it just doesn't work.
WDYT?

@jnopnop the image is available, and you should be able to pull it. Try to restart your docker daemon and remove Aerospike images before.

The main issue is spring-data-aerospike providing it's test properties in production resources, thus overriding user properties.
@jnopnop please revert change with the version and leave only moving of the bootstrap.properties file to the test resources folder.
