Vikas Kumar added a comment - 2017-03-02 08:36 Hello wolfs , There is nothing in logs. In Debian, only installing graphviz does the job, looks like I am missing few packages in Alpine. # docker logs -f jenkins_master Running from: /usr/share/jenkins/jenkins.war webroot: EnvVars.masterEnvVars.get("JENKINS_HOME") Mar 02, 2017 8:33:07 AM Main deleteWinstoneTempContents WARNING: Failed to delete the temporary Winstone file /tmp/winstone/jenkins.war Mar 02, 2017 8:33:07 AM org.eclipse.jetty.util.log.JavaUtilLog info INFO: Logging initialized @1612ms Mar 02, 2017 8:33:08 AM winstone.Logger logInternal INFO: Beginning extraction from war file Mar 02, 2017 8:33:08 AM org.eclipse.jetty.util.log.JavaUtilLog warn WARNING: Empty contextPath Mar 02, 2017 8:33:08 AM org.eclipse.jetty.util.log.JavaUtilLog info INFO: jetty-9.2.z-SNAPSHOT Mar 02, 2017 8:33:09 AM org.eclipse.jetty.util.log.JavaUtilLog info INFO: NO JSP Support for /, did not find org.eclipse.jetty.jsp.JettyJspServlet Jenkins home directory: /var/jenkins_home found at: EnvVars.masterEnvVars.get("JENKINS_HOME") Mar 02, 2017 8:33:10 AM org.eclipse.jetty.util.log.JavaUtilLog info INFO: Started w.@6e6f2380{/,file:/var/jenkins_home/war/,AVAILABLE}{/var/jenkins_home/war} Mar 02, 2017 8:33:10 AM org.eclipse.jetty.util.log.JavaUtilLog info INFO: Started ServerConnector@1ca3b418{HTTP/1.1}{0.0.0.0:8080} Mar 02, 2017 8:33:10 AM org.eclipse.jetty.util.log.JavaUtilLog info INFO: Started @3865ms Mar 02, 2017 8:33:10 AM winstone.Logger logInternal INFO: Winstone Servlet Engine v2.0 running: controlPort=disabled Mar 02, 2017 8:33:10 AM jenkins.InitReactorRunner$1 onAttained INFO: Started initialization Mar 02, 2017 8:33:11 AM jenkins.InitReactorRunner$1 onAttained INFO: Listed all plugins Mar 02, 2017 8:33:11 AM jenkins.bouncycastle.api.SecurityProviderInitializer addSecurityProvider INFO: Initializing Bouncy Castle security provider.

Fürbacher added a comment - 2017-03-15 12:31 - edited I noticed, that this issue occures, if we use special characters in display names of projects, such as ampersands and that name get put in the label parameter of a diagraph node. Then dot also throws an error, if I manually run dot with the generated graph.vz file:   Error: not well-formed (invalid token) in line 1 ... <td align= "center" href= "http: //myjenkinsinstance/job/MyJob/" >X & Y ... in label of node X & Y   When I manually escape the ampersand character in the generated graph.vz file, then dot can gerate a valid image. I think, there's some problem with special characters that should get escaped. Maybe in this method.
