[英]Exposing docker container ports not working
I am having trouble exposing a port from a docker container to my server. 我在将端口从Docker容器暴露到服务器时遇到麻烦。 Here is what I've done:
这是我所做的:
I wrote a very simple spring boot app that runs on port 8080. 我编写了一个非常简单的spring boot应用程序,该应用程序在端口8080上运行。
Now I am trying to deploy it into a docker container on my server. 现在,我正在尝试将其部署到服务器上的docker容器中。 Based on the Spring - Getting started with Docker Userguide I've created the following Dockerfile:
基于春季 -Docker用户指南入门,我创建了以下Dockerfile:
FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
In a second step I copied my jar to the same directory (where the dockerfile is stored) and built the container with the following command: 在第二步中,我将jar复制到了相同的目录(存储dockerfile的目录),并使用以下命令构建了容器:
docker build . -t testportmapping --build-arg JAR_FILE=swagger-v2-person-ws-0.0.1-SNAPSHOT.jar
Now when I run: 现在,当我运行时:
docker run -d testportmapping:latest -p 9065:8080
The command runs without an error. 该命令运行无错误。 But if I take a look at:
docker container ls
: I see that no portmapping was created: 但是,如果我看一下:
docker container ls
:我发现没有创建端口映射:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f15639c81903 testportmapping:latest "java -Djava.securit…" About 6 minutes ago Up 6 minutes mystifying_payne
Does anyone know that I am doing wrong? 有人知道我做错了吗?
--net=host
to the docker run
command --net=host
到--net=host
docker run

Image name should be the last parameters and all other parameters should come before it. 映像名称应为最后一个参数,所有其他参数应位于其后。
PS As mentioned by @David Maze in the comments, whatever comes after the image name is passed on to the container PS正如@David Maze在评论中提到的,将映像名称传递到容器之后的内容
