Nicolas Ferrario commented on FLINK-28057:
------------------------------------------

Hi [~yunta]. Flink is building official ARM images since 1.15 as far as I know, 
right? ([https://hub.docker.com/_/flink])

Everything works perfectly except for jemalloc, which doesn't prevent Flink 
from starting anyway.

 

A current workaround is to use these configs:
{code:yaml}
containerized.jobmanager.env.DISABLE_JEMALLOC: true
containerized.jobmanager.env.LD_PRELOAD: 
/usr/lib/aarch64-linux-gnu/libjemalloc.so
containerized.taskmanager.env.DISABLE_JEMALLOC: true
containerized.taskmanager.env.LD_PRELOAD: 
/usr/lib/aarch64-linux-gnu/libjemalloc.so 
{code}

> LD_PRELOAD is hardcoded to x64 on flink-docker

> ARM images are not using jemalloc because LD_PRELOAD is hardcoded to use an 
> x64 path, causing this error:
> {noformat}
> ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libjemalloc.so' from 
> LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
> {noformat}
> Right now docker-entrypoint is using this:
> {code:sh}
> maybe_enable_jemalloc() {
>     if [ "${DISABLE_JEMALLOC:-false}" == "false" ]; then
>         export LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libjemalloc.so
>     fi
> }
> {code}
> I propose we use this instead:
> {code:sh}
> maybe_enable_jemalloc() {
>     if [ "${DISABLE_JEMALLOC:-false}" == "false" ]; then
>         # Maybe use export LD_PRELOAD=$LD_PRELOAD:/usr/lib/$(uname 
> -i)-linux-gnu/libjemalloc.so
>         if [[ `uname -i` == 'aarch64' ]]; then
>             export 
> LD_PRELOAD=$LD_PRELOAD:/usr/lib/aarch64-linux-gnu/libjemalloc.so
>         else
>             export 
> LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libjemalloc.so
>         fi
>     fi
> }
