Docker tomcat editing configuration files through dockerfile
I figured it out. The problem was that the user with which I was executing the build tasks did not have sufficient rights to write stuff in those folders. What I did was add a USER root task to the Dockerfile so it executes all the commands as root.
My Dockerfile now looks like this:
FROM tomcat
USER root
COPY tomcat-users.xml /usr/local/tomcat/conf/
COPY context.xml /usr/local/tomcat/webapps/manager/META-INF/
CMD ["catalina.sh","run"]

I have created a dockerfile and docker-compose like below, which is suppost to create an image of tomcat inside my container and edit the tomcat users so that I am able to access the manager gui.
The four files below are all in the same folder as where I run the docker-compose up command.docker-compose.yml
version: '2' services: tomcat: build: . container_name: development ports: - 8001:8080 environment: - spring.profiles.active=development
Dockerfile
FROM tomcat COPY tomcat-users.xml /usr/local/tomcat/conf/ COPY context.xml /usr/local/tomcat/webapps/manager/META-INF/ CMD ["catalina.sh","run"]
tomcat-users.xml
<?xml version='1.0' encoding='cp1252'?> <tomcat-users xmlns="http://tomcat.apache.org/xml" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd" version="1.0"> <user username="manager" password="pass" roles="manager-gui,manager-script"/> <user username="admin" password="pass" roles="tomcat"/> </tomcat-users>
context.xml
<?xml version="1.0" encoding="UTF-8"?> <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>
when I run the command docker-compose up, it generates the container with a tomcat image perfectly, but the existing tomcat-users.xml and context.xml didn't get overwritten. Any idea what I'm doing wrong to overwrite those two files?
