+# Red Hat Enterprise Linux / CentOS SELinux policy module for GitBucket
+
+One way to run GitBucket on Enterprise Linux is under Tomcat. Since EL 7.4, Tomcat is no longer unconfined.
+Thus since 7.4, Enterprise Linux blocks certain operations that are required for GitBucket to work properly:
+
+* Tomcat is not allowed to connect to SMTP ports, which is required to send email notifications.
+* Tomcat is not allowed to execute files, which is required for creating repositories.
+* Tomcat is not allowed to act as a server on unreserved ports, which is required for serving repositories via SSH.
+
+To mitigate this, you can use the SELinux policy module provided as `gitbucket.te`. You can deploy the module with the
+attached script, e.g.:
+
+~~~
+./sedeploy.sh gitbucket
+~~~
+
+You most likely also need to fix file contexts on your system. Assuming a new, default Tomcat installation on 7.4, you
+can do so by issuing the following commands:
+
+~~~
+GITBUCKET_HOME='/usr/share/tomcat/.gitbucket'
+mkdir -p ${GITBUCKET_HOME}
+chown tomcat.tomcat ${GITBUCKET_HOME}
+semanage fcontext -a -t tomcat_var_lib_t "${GITBUCKET_HOME}(/.*)?"
+restorecon -rv ${GITBUCKET_HOME}
+
+JAVA_CONF='/usr/share/tomcat/.java'
+mkdir -p ${JAVA_CONF}
+chown tomcat.tomcat ${JAVA_CONF}
+semanage fcontext -a -t tomcat_cache_t "${JAVA_CONF}(/.*)?"
