你好，请问你是用什么工具将项目拷贝服务器中的？谢谢

ityouknow commented 6 years ago

@xiah217 什么都可以呀， ssh工具，rz等

winscp应该也可以吧

TanqiZhou commented 6 years ago

我想知道日志去哪里了

ityouknow commented 6 years ago

@TanqiZhou 就在容器里面

xiah217 commented 6 years ago

为什么在用mvn package docker:build构建镜像的时候一直显示 Downloading from central: https://repo.maven.apache.org/maven2/org/apache/maven/maven-archiver/3.1.1/maven-archiver-3.1.1.pom

你的文档应该再进一步，加入用docker-compose的部分

博主已经写了相关的，你自己找

HyggeBo7 commented 6 years ago

docker run -p 7106:7106 -t springboot/spring-boot-docker 他不会后台运行唉

ityouknow commented 6 years ago

@wubodanran 加上 -d 参数，类似下面：

docker run -d -p 7106:7106 -t springboot/spring-boot-docker

xiah217 commented 6 years ago

博主，我写了两个不相关的项目a和b，分别已经得到对应的镜像springboot/a 和 springboot/b，为什么我只能docker run一个镜像，当运行另外一个镜像时就会把前面跑起来的镜像挤下去，端口没有冲突，谢谢你！

mvn package docker:build时报错：

怎么破？

为什么是在centos中安装环境，不是用docker镜像安装。

maven和jdk都不是镜像安装的，有问题吗？

chyitboy commented 6 years ago

docker 安装mysql其他机器访问没问题，部署到本机就不行了，这么咋搞

kely39 commented 6 years ago

我的也没成功之后还没去跟踪了，你的maven是镜像安装的吗？

你好，我已经参照本篇博文操作成功了。 Maven不是安装的docker镜像，而是直接安装在你的远程Linux服务器上的。

huowolf commented 6 years ago

@gistmap 为什么是在centos中安装环境，不是用docker镜像安装。

我的理解：因为需要在远程服务器上手动使用Maven构建docker镜像，所以需要Maven环境，而maven环境依赖于Java环境。所以Java和Maven都需要你自己安装了。

我也参照本篇博文操作成功了。我的理解是:项目还是需要自己构建，pom中的docker-maven-plugin 只是在maven打完包后将打包后的内容利用插件中配置的参数结合docker:build命令构建docker镜像发布到docker容器中，当容器中存在我们已经发布上去的项目时，直接运行docker run启动即可。关于项目的构建还是需要在本地构建才行，docker-maven-plugin只是当本地（本地已安装docker环境）执行docker:build时传递相关的参数。

请问当springboot项目更新的时候如何重新部署？难道每次都要重新创建运行docker镜像吗？再比如ADD ./nginx.conf /etc/nginx/nginx.conf，当修改了./nginx.conf文件的时候如何重新生效？

cuisea commented 6 years ago

学习了

BonnieCabrera commented 5 years ago

首先要有一台linux服务器

JellyB commented 5 years ago

嗯，讲的不错！

wuqiupeng commented 5 years ago

mvn package docker:build 报异常的，把docker-maven-plugin插件版本改成0.4.11就可以了（Mac ，linux好像没问题）

damangueyu commented 5 years ago

博主 dockerfile 中 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
java -jar /app.jar 是什么意思？

ADD springboot.jar app.jar app.jar是什么意思？求解答

linux-chaina commented 5 years ago

请问怎么开启远程debug 启动的时候加了这个参数 docker run -e "JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,address=5005,server=y,suspend=n"

报错:Error: Could not find or load main class $JAVA_OPTS

怎么破？检查你的pom构建文件中标签值是否有大写字母。。无意间加了的大写字母问题排除了一个多小时。。。。
