I installed Docker on my Windows Server 2012 R2 machine and tried to use the Keycloak Docker image. I ran "docker run -it -p 8080:8080 -p 9090:9090 jboss/keycloak" and received the following error: java.lang.IllegalArgumentException: Failed to instantiate class "org.jboss.logma nager.handlers.PeriodicRotatingFileHandler" for handler "FILE" at org.jboss.logmanager.config.AbstractPropertyConfiguration$ConstructAc tion.validate(AbstractPropertyConfiguration.java:119) . . . at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at org.jboss.logmanager.config.AbstractPropertyConfiguration$ConstructAc tion.validate(AbstractPropertyConfiguration.java:117) ... 19 more Caused by: java.io.FileNotFoundException: /opt/wildfly/standalone/log/server.log (No such file or directory) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.<init>(FileOutputStream.java:221) Any ideas?
