Sonarqube has docker server configuration requirements. Same as in the document description.
Because SonarQube uses an embedded Elasticsearch, make sure that your
Docker host configuration complies with the Elasticsearch production
mode requirements and File Descriptors configuration.
For example, on Linux, you can set the recommended values for the
current session by running the following commands as root on the host:
sysctl -w vm.max_map_count=524288
sysctl -w fs.file-max=131072
ulimit -n 131072
ulimit -u 8192
For windows with docker wsl, I have configured
wsl -d docker-desktop
sysctl -w vm.max_map_count=524288
sysctl -w fs.file-max=131072
ulimit -n 131072
And it seems to have worked correctly.
Hope this helps you.
