Description
I'm puzzled by crashes at runtime of SonarQube built on top of openjdk:8-alpine, on Linux hosts.
Relevant log from the crash of SonarQube 6.7.5-alpine:

Relevant log from the crash of SonarQube 6.7.6-community-alpine, same as from 7.4-community-alpine:
2018.11.23 10:56:06 INFO app[][o.s.a.p.ProcessLauncherImpl] Launch process[[key='web', ipcIndex=2, logFilenamePrefix=web]] from [/opt/sonarqube]: /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djava.io.tmpdir=/opt/sonarqube/temp -Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -Djava.security.egd=file:/dev/./urandom -cp ./lib/common/*:/opt/sonarqube/lib/jdbc/h2/h2-1.3.176.jar org.sonar.server.app.WebServer /opt/sonarqube/temp/sq-process8139424421906286412properties
Error: Could not find or load main class org.sonar.server.app.WebServer
I run the built images with the simplest possible command, docker run imagename.
If I do the same on OSX, it works, I only get the above errors on Linux.
I see others have similar issues, strangely on first run only. For example if I run docker run -it imagename bash, and then within the container /opt/sonarqube/bin/run.sh, the first run fails and the 2nd and subsequent runs work fine.
What's going on?
- How can it work on OSX but not on Linux hosts?
- How can it work for 2nd+ runs but not for the first?
