SonarQube - max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

公司個project 開始成形… 係時候要用D tools 去 做多D checking 去 ensure D code quality 係 OK…
朋友介紹可以用 SonarQube run D test 去Scan 下個project 有無 potential issue
bugs / vulnerability / code smell 等等
為左唔好係部電腦上 install 太多野.. 所以都用docker 係local 度run SonarQube
當我嘗試 docker-compose 時 出現左以下個 error message

max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

解決方法
只要係部機/VM 度 allocate 足夠 memory 便可
由於我個docker host 係 Ubuntu 所以我可以執行下面個command 便可

sudo sysctl -w vm.max_map_count=262144

hope you find it useful
