Dockerfile 與 Tomcat catalina.sh 運行不運行

Question

我可以構建 Dockerfile。 當我執行 docker 運行 -it path-to-image/tomcat9:latest 並檢查日志時，沒有 catalina.out 並且運行失敗並獲取 /bin/sh: ["catalina.sh",: command not成立。

這是我的 Dockerfile

FROM gitlab-registry.gs.mil/gets-development/docker/openjdk11

USER root

# Copy Tomcat and start
ADD imageFiles/apache-tomcat-9.0.65.tar.gz /usr/local/
RUN mv /usr/local/apache-tomcat-9.0.65/ /usr/local/tomcat

ENV WORKPATH /usr/local
WORKDIR $WORKPATH

ENV CATALINA_HOME /usr/local/tomcat
ENV CATALINA_BASE /usr/local/tomcat

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

EXPOSE 8080
CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]

構建命令：

docker build -t gitlab-registry.gs.mil/gets-development/docker/tomcat9-test .

啟動命令：

docker run --name tomcatTest -it gitlab-registry.gs.mil/gets-development/docker/tomcat9-test:latest /bin/bash

嘗試在 docker 容器內連接到本地主機失敗

curl: (7) Failed to connect to localhost port 8080: Connection refused

沒有日志文件

[root@b058163e9605 local]# cd tomcat/logs/
[root@b058163e9605 logs]# ls -als
total 0
0 drwxr-x--- 2 root root   6 Jul 14 12:28 .
0 drwxr-xr-x 9 root root 220 Aug  5 16:17 ..
[root@b058163e9605 logs]# 

這告訴我 Tomcat 沒有啟動。 在容器內啟動Tomcat，tomcat可以啟動成功：

[root@b058163e9605 bin]# ./catalina.sh run

最后，我檢查了 Docker 日志，顯示了我在容器內做了什么，但沒有其他信息。

請協助。

Answer 1

您的docker run命令不會啟動 Tomcat，而只是啟動 bash。 注意最后一個參數

docker run --name tomcatTest -it gitlab-registry.gs.mil/gets-development/docker/tomcat9-test:latest /bin/bash

把它改成

docker run --name tomcatTest gitlab-registry.gs.mil/gets-development/docker/tomcat9-test:latest

如果您想要 shell 調查正在運行的容器內發生的情況，請使用

docker exec -it tomcatTest /bin/bash
