The username you provided is not allowed to use the text-based Tomcat Manager (error 403) when deploying on remote Tomcat8 using Jenkins

This seems to be a Jenkins bug but I got around the problem by setting up following configuration in Tomcat:

Edit the file /webapps/manager/META-INF/context.xml:

Previous:

<Context antiResourceLocking="false" privileged="true">
  <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
</Context>

Change this file to comment the Value:

<Context antiResourceLocking="false" privileged="true">
  <!--
    <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
    -->
</Context>

This resolved the issue. Hope this helps someone :)

I was facing the same issue while deploying artifact to tomcat with jenkins via container plugin, Solution:- i have added manager-script and manager-gui in the roles of the user and provide the full access to webapps/* directory. It helps me to deploy the artifact successfully and able to view it with manager-app.
