问题描述

今天在本地修改了代码,通过docker上传后,却发现代码不是最新的,启动监听的端口也不对.

查看启动日志,发现里面的jar包名称也不对.

编译及上传、下载docker包步骤
  2. 本地编译并打tag
    gradle build -x test
    docker build -t shell_note_server .
    docker tag ktor-sample:latest registry.cn-hangzhou.aliyuncs.com/cxyzy/shell_note_server:1.0.1
  3. 登陆并上传
    docker login --username=阿里云用户ID registry.cn-hangzhou.aliyuncs.com
    docker push registry.cn-hangzhou.aliyuncs.com/cxyzy/shell_note_server:1.0.1
  4. 在服务拉取镜像并启动
    先切换到root用户下,再执行如下命令:
    docker login --username=阿里云用户ID registry.cn-hangzhou.aliyuncs.com
    docker pull registry.cn-hangzhou.aliyuncs.com/cxyzy/shell_note_server:1.0.1
    docker run -m512M --cpus 1 -it -p 80:8080 -p 443:8443 --rm registry.cn-hangzhou.aliyuncs.com/cxyzy/shell_note_server:1.0.1
原因

在本地打tag的步骤错了,下面的ktor-sample是我之前写的一个demo,应该更新为本次的shell_note_server

docker tag ktor-sample:latest registry.cn-hangzhou.aliyuncs.com/cxyzy/shell_note_server:1.0.1

修改后:

docker tag shell_note_server:latest registry.cn-hangzhou.aliyuncs.com/cxyzy/shell_note_server:1.0.1

重复之后该步骤后续步骤,搞定.
