我目前正在做什么：

Dockerfile：

FROM python:3.5.1

ENV PYTHONUNBUFFERED 1

RUN mkdir /www
WORKDIR /www
ADD deps.txt /www/
RUN pip3 install -r deps.txt
ADD . /www/
RUN chmod 0755 /www/docker-init.sh

生成命令：

docker build -t my-djnago-app:latest .

标记：

docker tag my-djnago-app:latest lolorama/my-djnago-app-img:latest

推动：

docker push lolorama/my-djnago-app-img:latest

完成这些步骤后，存储库映像仍未更新。我不断收到此消息-“图层已存在”。

The push refers to a repository [docker.io/lolorama/my-django-app-img]

我究竟做错了什么？
