JNA temporary directory '/tmp' is not writable

Elastic Stack Elasticsearch
1

I am train to use this YML in a Oracle Container Cloud Service:

version: 2
services:
_ elasticsearch:_
_ image: 'docker.elastic.co/elasticsearch/elasticsearch:6.3.2'_
_ ports:_
_ - '9200:9200/tcp'_
_ - '9300:9300/tcp'_
_ hostname: elasticsearch_
_ container_name: elasticsearch_
_ environment:_
_ - discovery.type=single-node_
_ - ES_TMPDIR=/tmp_
_ - ES_JAVA_OPTS=-Xms512m -Xmx512m_
_ - ES_JVM_OPTS="$JVM_OPTS -Djna.tmpdir=/var/tmp"_
_ volumes:_
_ - 'elasticsearch:/usr/share/elasticsearch/data'_

Unfortunately, I am receiving this error:

018-08-07T23:50:13.172253813Z OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

etc...

Could someone help me to check what values is incorrect in my YML file?

It looks like you have /tmp not writable on your system. I see you try to set the jna tmpdir, but in ES_JVM_OPTS, which is not an env var elasticsearch looks for.

Hi Ryan, I have updated the YML file again:

version: 2
services:
** elasticsearch:**
** image: 'docker.elastic.co/elasticsearch/elasticsearch:6.3.2'**
** ports:**
** - '9200:9200/tcp'**
** - '9300:9300/tcp'**
** hostname: elasticsearch**
** container_name: elasticsearch**
** environment:**
** - discovery.type=single-node**
** - ES_JAVA_OPTS=-Djna.tmpdir=/var/lib.elasticsearch/tmp**
** - ES_TMPDIR=/tmp**
** volumes:**
** - 'elasticsearch:/usr/share/elasticsearch/data'**

and the issue is still happening... I checked using ** image: 'docker.elastic.co/elasticsearch/elasticsearch:6.3.1'** and it workd without errors (weird, isnt?

this is the new output (any idea...?):

Does the directory actually exist?

I dont think so because I am running a docker container... I assume when the container starts the directories are created, but not before...
