Binary builds have a glibc version error

$ docker pull registry.gitlab.com/teklia/arkindex/backend:latest-binary
$ docker run -it registry.gitlab.com/teklia/arkindex/backend:latest-binary
arkindex: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by arkindex)

I can't test !2008 (merged) locally ;_;
