Question

我想替换docker映像中的文本 所以我用ENV代替文字

但是当我将文本放入ENV时，不会覆盖ENV

当我运行docker image时，应将ssl文件中的docker run -d -e "SERVER_NAME=docker.havehad.kr" --name nginx-ssl -p 443:443 --rm nginx-ssl 替换为'docker.havehad.kr'，但没有这样做
它仍然保留为“ myserver.com”
不知道是什么问题
请帮助我

Answer 1

在处理docker映像时，您有2个不同的上下文： build 上下文（docker build命令）和 run 上下文（docker run命令）。

来自dockerfile reference：

ENV指令将环境变量设置为value。此值将在构建阶段的所有后续指令所在的环境中使用，并且也可以内联替换为许多值。

ARG指令定义了一个用户可以在其处传递的变量 使用docker build命令构建到构建器的时间 --build-arg =标志。如果用户指定了Dockerfile中未定义的构建参数，则构建输出 警告。

似乎您需要一种方法来更改Dockerfile中使用的变量以更改sed命令。您应该使用参数来实现这一点，并且可以将它们与环境变量组合以在运行时使它们可用（docker run命令）

RUN apt-get update
RUN apt-get install -y nginx
RUN echo "\ndaemon off;" >> /etc/nginx/nginx.conf

# Define mountable directories.
VOLUME ["/etc/nginx/sites-enabled", "/etc/nginx/certs", "/etc/nginx/conf.d", "/var/log/nginx", "/var/www/html"]

ARG PROXY_PASS=http://localhost:3000
ARG SERVER_NAME=myserver.com
ARG PEM_PATH=/etc/nginx/certs/cert.pem
ARG KEY_PATH=/etc/nginx/certs/cert.key

ENV PROXY_PASS ${PROXY_PASS}
ENV SERVER_NAME ${SERVER_NAME}
ENV PEM_PATH ${PEM_PATH}
ENV KEY_PATH ${KEY_PATH}


WORKDIR /etc/nginx

RUN rm -f sites-enabled/default
ADD ./sites-available/ssl /etc/nginx/sites-available/ssl
RUN sed -ri 's@PROXY_PASS@${PROXY_PASS}@' sites-available/ssl
RUN sed -ri 's@SERVER_NAME@${SERVER_NAME}@' sites-available/ssl
RUN sed -ri 's@PEM_PATH@${PEM_PATH}@' sites-available/ssl
RUN sed -ri 's@KEY_PATH@${KEY_PATH}@' sites-available/ssl
RUN cp -f sites-available/ssl sites-available/default
#RUN ln -s /etc/nginx/sites-available/ssl sites-enabled/default

EXPOSE 80 443

CMD ["nginx"]

并且您可以在构建图像时更改参数值：

$ docker build --build-arg SERVER_NAME=docker.havehad.kr .

您的${SERVER_NAME}参数将在Dockerfile指令（ENV和RUN）中替换为docker.havehad.kr。

如果需要在运行时（docker运行）更改sed命令，请将其放入shell脚本中并用作ENTRYPOINT
