Jenkins docker 容器无法将 war 文件部署到 tomcat docker 容器

Question

我无法让 Jenkins 在 Tomcat8 服务器上部署 war 文件。为什么 Jenkins 不能部署到 Tomcat？

当我运行 Jenkins 工作时，我遇到了这个异常：

[DeployPublisher][INFO] Deploying /var/jenkins_home/workspace/Deploy_to_Tomcat_server/webapp/target/webapp.war to container Tomcat 8.x Remote with context null
ERROR: Build step failed with exception
java.net.ConnectException: Connection refused (Connection refused)

我认为docker两个容器都有问题，所以我将描述我所做的事情。

Jenkins 服务器和 Tomcat8 都在运行我本地机器上 docker 容器中。为了让双方都能看到对方，我创建了一个公共网络。

~ % docker network ls
NETWORK ID     NAME                            DRIVER    SCOPE
da6fc157710c   bridge                          bridge    local
...
// network bridge already exists!

我可以同时检查容器和新网络：

~ % docker network ls
NETWORK ID     NAME                            DRIVER    SCOPE
da6fc157710c   bridge                          bridge    local
378ef3f01e21   my_jenkins_tomcat_network       bridge    local

~ % docker inspect my_jenkins_tomcat_network

            }
        },
        "Options": {},
        "Labels": {}
    }
]

我可以在 Jenkins 容器中执行 bash 并 ping tomcat 容器：

~ % docker container ls
CONTAINER ID   IMAGE                 COMMAND                  CREATED             STATUS             PORTS                               NAMES

64 bytes from 172.23.0.3: seq=1 ttl=64 time=0.139 ms
...

在我的 tomcat 容器中，我修改了 tomcat-users.xml 文件，默认内容为：

    <role rolename="manager-gui"/>
    <role rolename="manager-script"/>
    <role rolename="manager-jmx"/>
    <role rolename="manager-status"/>
    <user username="tomcat" password="tomcat" roles="manager-gui"/>
    <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>
    **<user username="deployer" password="deployer" roles="manager-script"/>**

当我创建 Jenkins 作业时，我使用凭证部署器和 tomcat url，如上所示

我也尝试过使用内部 ip，172.23.0.3，没有运气。

我看过thislink，没有回复，有点不一样，所以我觉得回答这个问题是合理的。

实现此目标的一种方法是安装此 plugin，在 tomcat 容器中配置 sshd 并在 Jenkins 中创建一个 post 任务以复制 war 文件到 webapps 文件夹。

Jenkins docker 容器无法将 war 文件部署到 tomcat docker 容器

Jenkins docker container cannot deploy war file to tomcat docker container

jenkins
