7.3 image does not work with overlay2 driver

Open alexandru-2016 opened this issue 5 years ago • 3 comments

Hello,

There seems to be a bug in java, which causes this error when running on overlay2 docker driver

[2020-03-03T09:49:24,727][ERROR][org.elasticsearch.bootstrap.Bootstrap] Exception java.lang.IllegalStateException: failed to obtain node locks, tried [[/usr/share/elasticsearch/data]] with lock id [0]; maybe these locations are not writable or multip at org.elasticsearch.env.NodeEnvironment.(NodeEnvironment.java:299) ~[elasticsearch-7.3.2.jar:7.3.2] .....

Similar issue is also discussed here: https://github.com/pires/kubernetes-elasticsearch-cluster/issues/89

Maybe the version of Java used in this image doesn't include the fix for this bug

alpine 3.11 doesn't have the fix either

I was able to workaround using java 8, and changed the Dockerfile like this

-RUN apk add --no-cache openjdk11-jre-headless su-exec +RUN apk add --no-cache openjdk8-jre su-exec

I do get this warning now, but I can live with it

future versions of Elasticsearch will require Java 11; your Java version from [/usr/lib/jvm/java-1.8-openjdk/jre] does not meet this requirement

Also, as a bonus, the image size decreased an extra 90 MB, and is 197MB now

Thank you for doing this research! Hopefully alpine 3.11 or 3.12's java will fix this? I'll pin this for now, as I am not sure it is better to use old Java to support overlay2 or to wait for better Java 11.
