es-head does not support building with ARM64 and had to be replaced with the even better elasticvue
elasticvue will now run within the nginx container, freeing some RAM :) on the way
Setting static limits for Elasticsearch / Logstash on Xms, Xmx and Container RAM results in unwanted side effects for some installations. With Elastic supporting dynamic heap management for Java 14+ we now use OpenJDK 16 JRE and as such remove limitations. This should improve stability for T-Pot, provided the minimum requirements will be met.
