关于docker镜像的基础镜像没有固定版本导致的运行出错

由于未指定基础镜像版本，导致拉取到最近的python3.10后不兼容旧版代码出错

将原Dockerfile中的python:rc-alpine3.13

FROM python:rc-alpine3.13

RUN pip3 install speedtest-cli

ENTRYPOINT ["speedtest-cli"]

改为python:3.7.10-alpine3.13，将基础镜像限制为python:3.7

FROM python:3.7.10-alpine3.13

RUN pip3 install speedtest-cli

ENTRYPOINT ["speedtest-cli"]
