docker - 为什么docker容器启动成功时tomcat没有启动？

Question

tomcate 和 jdk 从他们的官方网站下载

以下是我的 Dockerfile：

FROM centos
MAINTAINER jachen<[e-mail]>
COPY readme.txt /usr/local/readme.txt

ADD jdk-8u261-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.22.tar.gz /usr/local/

#RUN yum -y install vim

ENV MYPATH /usr/local
WORKDIR $MYPATH

ENV JAVA_HOME /usr/local/jdk1.8.0_261
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.22
ENV CATALINA_BASH /usr/local/apache-tomcat-9.0.22

ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin

EXPOSE 8080

CMD ["/usr/local/apache-tomcat-9.0.22/bin/catalina.sh" "run"]

构建命令：

docker build -t diytomcat3:0.3 .

启动命令：

docker run -it -d diytomcat3:0.3 /bin/bash

然后进入码头：

[root@localhost ~]# docker exec -it cb4aebe4a834 /bin/bash
[root@cb4aebe4a834 local]# pwd
/usr/local
[root@cb4aebe4a834 local]# curl localhost:8080
curl: (7) Failed to connect to localhost port 8080: Connection refused
[root@cb4aebe4a834 local]# 

这意味着 tomcat luanch 失败了。

但是当运行 catalina.sh 时，tomcat 可以启动成功：

[root@cb4aebe4a834 local]# catalina.sh run

Using CATALINA_HOME:   /usr/local/apache-tomcat-9.0.22

Using CLASSPATH:       /usr/local/apache-tomcat-9.0.22/bin/bootstrap.jar:/usr/local/apache-tomcat-9.0.22/bin/tomcat-juli.jar

我试图获取一些日志，但一无所获：

[root@localhost ~]# docker ps
