Feature request: more efficient elasticsearch docker image #50838
Description
Describe the feature:
When calculating the efficiency score of the elasticsearch 7.4.0 image with https://github.com/wagoodman/dive the image receives a very bad score of 81% efficiency and a potential wasted space of 305MB.
The wasted space includes files like
Total Space Path
35 MB /var/lib/rpm/Packages
11 MB /usr/bin/ld.gold
6.4 MB /usr/bin/dwp
5.1 MB /usr/lib/locale/locale-archive
5.0 MB /usr/lib64/libcrypto.so.1.0.2k
4.3 MB /usr/lib64/libc-2.17.so
3.7 MB /usr/lib64/libdb-5.3.so
3.7 MB /usr/lib64/libpython2.7.so.1.0
3.5 MB /var/lib/rpm/Providename
For which it's questionable whether they're used at runtime. Perhaps the image can be made more efficient by moving all the COPY steps to the top, combining all the RUN statements (resulting in 1 layer) and cleaning unused files added during the RUN steps.
You can run the analysis with the following commands:
brew install dive
dive docker.elastic.co/elasticsearch/elasticsearch:7.4.0
