vm.max_map_count [65530] is too low during deployement

Hi everyone, I currently try to deploy a SonarQube application on Railway and during deployement, I got the following error : max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

Do you know where this error can come from ?

I'm Hobby plan, normally I have 8 GB RAM / 8 vCPU per Service.
Or it is because Railway cannot host Elastic Search anymore as I understand ?

Have a good day guys 😉

@interstellartaco is the java dood

Try adding a JAVA_OPTS=-Dvm.max_map_count=262144 environment variable.

I've try but it doesn't work, I found this on the sonarqube dockerhub (https://hub.docker.com/_/sonarqube)

In the section "Docker Host Requirements", there is some command to run before running the image

sysctl -w vm.max_map_count=524288
sysctl -w fs.file-max=131072
ulimit -n 131072
ulimit -u 8192

Do you think it is possible to configure the docker host from environement variable of railway ?
If it's not possible, I will try to use DinD to create my own environnement

its not

I will try to use DinD to create my own environment

thats also not possible on railway
lets wait and see if aleks can come up with something else

For DinD, it's for security reasons ? Or infrastructure ? Or another reason ?

the containers are not started with the permissions to allow that

Okay ^^

Hmm, I think this is actually a Railway infra thing
@jr since I'm not sure who to ping for what any more (sorry if I should have pinged someone else) - thoughts on increasing various system limits?

is this not a setting for the java virtual machine?

Nop unfortunately it's a setting for the docker host

In the source code of sonarqube, there is already this environment variable set : https://github.com/SonarSource/sonarqube/blob/12639b9a55950a24a971eeee7044e474dbb72e46/server/sonar-main/src/main/java/org/sonar/application/es/EsSettings.java#L165
And I don't think it's rewrite elsewhere because I dind't find any other occurance of this key inside the repository
I think sonar is not compatible with railway, don't spend more time on this issue, thanks for your help
