I am trying to view a small demo of Siren on my Windows desktop with WSL. Running Elasticsearch on WSL does not usually work out of the box because the vm.max_map_count
value is too low (65530, ES needs at least 262144) – vm.max_map_count in docker-desktop distro for WSL2 · Issue #5202 · docker/for-win · GitHub
The recommended workaround for development is to set discovery.type=single-node
.
When I try that with both vanilla elasticsearch and siren-platform-demo-data, it works in ES but not Siren. If I do not include the discovery.type
environment variable in the ES container, then I see the same vm.max_map_count bootstrap error for Siren and vanilla ES.
Is there an environment setting or config I can set to turn off that bootstrap check in Siren?
Another suggested workaround is to update WSL wsl -d docker-desktop sysctl -w vm.max_map_count=262144
, which does work. Unfortunately that has to be done after every restart, and can’t be included as part of the docker-compose.yaml or anything.
