SEVERE [main] org.apache.catalina.startup.HostConfig.beforeStart Unable to create directory for deployment: [/usr/local/tomcat/conf/Catalina/localhost] Caused by: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myapp]]

When running a tomcat Docker image, this error appears, despite the container seems to go on with the execution:
SEVERE [main] org.apache.catalina.startup.HostConfig.beforeStart Unable to create directory for deployment: [/usr/local/tomcat/conf/Catalina/localhost] Caused by: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myapp]]

Steps to reproduce:
Distributor ID: Ubuntu
Description: Ubuntu 20.04.5 LTS
Release: 20.04
Codename: focal

Docker version 20.10.23, build 7155243

With the Docker image:

FROM tomcat:10.1.25-jdk17

#RUN mkdir -p /usr/local/tomcat/conf/Catalina/localhost #Hardcoding this privilege will obviously solve the problem

ADD ./asapianpr/asapianpr.war /usr/local/tomcat/webapps/
ADD ./asapianpr/ROOT /usr/local/tomcat/webapps/ROOT
RUN chown -R 8877:8877 /usr/local/tomcat/webapps/
RUN chmod -R g+rwx /usr/local/tomcat/webapps/

RUN chown -R 8877:8877 /usr/local/tomcat/temp/
RUN chmod -R g+rwx /usr/local/tomcat/temp/

RUN chown -R 8877:8877 /usr/local/tomcat/work/
RUN chmod -R g+rwx /usr/local/tomcat/work/

RUN mkdir -p /usr/local/tomcat/config
ADD ./asapianpr/config/asapianpr.settings /usr/local/tomcat/config/
RUN chown -R 8877:8877 /usr/local/tomcat/config/
RUN chmod -R g+rwx /usr/local/tomcat/config/

ADD ./setenv.sh /usr/local/tomcat/bin
RUN chown -R 8877:8877 /usr/local/tomcat/bin/
RUN chmod -R g+rwx /usr/local/tomcat/bin/

ENV TZ="Europe/Rome"

RUN useradd -ms /bin/bash -u 8877 user

USER user

EXPOSE 8080

CMD ["catalina.sh", "run"]

This seems to be a known old problem: #128 and #209 .

Start with the supplied Dockerfile, the tomcat:10.1.25-jdk17 image, and the catalina.sh entry point; reproduce the startup under USER user on Ubuntu 20.04. Review the related issues #128 and #209 for prior context. Done should include a confirmed cause and a documented startup behavior without the reported SEVERE error.
