RUN sysctl

Getting below error, when i try to build sonarqube image locally from docker file, this line is causing the issue RUN sysctl -w vm.max_map_count=262144

Step 7/12 : RUN sysctl -w vm.max_map_count=262144 ---> Running in dfc9a807faa1 sysctl: setting key "vm.max_map_count": Read-only file system The command '/bin/sh -c sysctl -w vm.max_map_count=262144' returned a non-zero code: 255

Below is my dockerfile code.

FROM openjdk:8

ENV SONAR_VERSION=7.8 SONARQUBE_HOME=/opt/sonarqube # Database configuration # Defaults to using H2 # DEPRECATED. Use -v sonar.jdbc.username=... instead # Drop these in the next release, also in the run script SONARQUBE_JDBC_USERNAME=sonar SONARQUBE_JDBC_PASSWORD=sonar SONARQUBE_JDBC_URL=
