It seems that we are re-copying the accumulator data on every docker version rebuild, which requires a huge download at deploy time.

Fixing this is probably as straightforward as moving the accumulator data copy before any steps that change in a data release (like the code build steps).

Same issue happens with both Dockerfiles I believe, in https://github.com/ethereum/trin/tree/7ab829a74fdd1c03d122ad19aee513fc76817aa3/docker
