Jenkins is not runnig jobs on the slave

I'm trying to launch a Jenkins agent through ECS. Below is my Dockerfile. When I start a job on this agent, ECS task shows PENDING and then STOPPED and the Jenkins job is stuck with a message that agent is offline. Am I making a mistake with the Jenkins file?

COPY jenkins-slave.sh /usr/local/bin/jenkins-slave.sh
RUN chmod 744 /usr/local/bin/jenkins-slave.sh

USER ${user}
ENV AGENT_WORKDIR=${AGENT_WORKDIR}
RUN mkdir /home/${user}/.jenkins && mkdir -p ${AGENT_WORKDIR}

VOLUME /home/${user}/.jenkins
VOLUME ${AGENT_WORKDIR}
WORKDIR /home/${user}
ENTRYPOINT ["jenkins-slave.sh"]

Solution

There was a permission issue with the entry point.
