Elasticsearch docker image

Did anyone manage to run elasticsearch docker image in Railway? I created a docker image service from elasticsearch:8.12.1 with the following env

ELASTIC_PASSWORD=SUPER_SECRET_PASSWORD
ELASTIC_USERNAME=elastic
discovery.type=single-node

ELASTIC_PASSWORD=SUPER_SECRET_PASSWORD
ELASTIC_USERNAME=elastic
discovery.type=single-node

but it keeps crashing with the following logs

loaded module [runtime-fields-common]

loaded module [x-pack-async]

loaded module [vector-tile]

loaded module [lang-expression]

loaded module [x-pack-eql]

fatal exception while booting Elasticsearch

ERROR: Elasticsearch did not exit normally - check the logs at /usr/share/elasticsearch/logs/docker-cluster.log

ERROR: Elasticsearch exited unexpectedly, with exit code 1

It runs fine locally with railway run docker run elasticsearch:8.12.1 I have no clue how to get said logs as the container dies on exit and I can't mount a volume on another path than /usr/share/elasticsearch/data

Solution:

looks like the image wants a volume mounted at /usr/share/elasticsearch/data instead

please send the full dockerfile you are using

Raigato•7mo ago

Sure, I am using the official elastic search image: https://hub.docker.com/layers/library/elasticsearch/8.12.1/images/sha256-f9a807ef8f888a9d3f9ab680bbb8917869e66d30b3d2f086eca796545040a2fe?context=explore Dockerfile: https://github.com/elastic/dockerfiles/blob/e15eb421da49ad627d48e5b3492948c76bcb8158/elasticsearch/Dockerfile

Brody•7mo ago

any reason why you are using a dockerfile instead of deploying the image directly? (I have never used elastic search before)

Raigato•7mo ago

I am using the image directly

Raigato•7mo ago

I think the solution is this: https://stackoverflow.com/a/53097050/13735374 but I have no idea how to pull this up in Railway

Brody•7mo ago

you can't, is that needed?

Raigato•7mo ago

I think so but I can't be sure as I can't access the logs when the container crashed after writing in the logs 🥲

Brody•7mo ago

why can't you mount a volume to /usr/share/elasticsearch/logs?

Raigato•7mo ago

When I do, I get this:

message.txt

Raigato•7mo ago

It somehow need a volume on /usr/share/elasticsearch/data to run

Brody•7mo ago

set a service variable RAILWAY_RUN_UID to 0

Raigato•7mo ago

Ok, it still doesn't work but I can move logs to the volume, I can investigate now 🙏

Brody•7mo ago

progress!

Raigato•7mo ago

Ok made some progress, it seems to be somehow related to volumes. With no volume attached, it works fine. When I mount a volume on /usr/share/elasticsearch, I get

/usr/local/bin/docker-entrypoint.sh: line 49: /usr/share/elasticsearch/bin/elasticsearch-env-from-file: No such file or directory

Also, I still have the vm.max_map_count=262144 thing (https://discord.com/channels/713503345364697088/1206911735399849984/1207002891022372967) but as I understand from your previous answer, I cannot change it, right ? Any solution ?
