nginx：无效选项：“off”和entrypoint.sh：：权限被拒绝

Question

我正在使用 Dockerfile 创建构建，然后通过 jenkins 作业部署该构建/映像，但容器状态为“CrashLoopBackOff”，当我检查日志时，出现以下错误。

错误：-

nginx: invalid option: "off"
/etc/nginx/entrypoint.sh: 5: /etc/nginx/entrypoint.sh: : Permission denied 

注意：- 授予entrypoint.sh 完全权限。（检查dockerfile）

Dockerfile：-

FROM node:12.18.4-alpine AS BUILD_IMAGE
WORKDIR /app

# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH

COPY package.json .
COPY package-lock.json .
COPY .npmrc .
RUN npm install
COPY . .
RUN npm run build

FROM nginx:latest
RUN apt-get update
RUN apt-get -y install sudo
COPY --from=BUILD_IMAGE /app/build /usr/share/nginx/html
COPY nginx/nginx.conf /etc/nginx/conf.d/default.conf
COPY .build/envs/uat/env.js /app/uat/env.js
COPY .build/envs/prod/env.js /app/prod/env.js
COPY entrypoint.sh /etc/nginx/entrypoint.sh
RUN  sudo chmod 777 /etc/nginx/entrypoint.sh
RUN  sudo nginx -t
RUN  ls -lrt /etc/nginx/

EXPOSE 80
ENTRYPOINT ["/etc/nginx/entrypoint.sh"]
# replace ENVIRONMENT with uat, prod
CMD ["ENVIRONMENT"]

入口点.sh 文件：-

#!/bin/sh
set -e

if [ "$1" = 'uat' ]; then
    "$(cp /app/uat/env.js /usr/share/nginx/html && nginx -g daemon off;)"
elif [ "$1" = 'prod' ]; then
    "$(cp /app/prod/env.js /usr/share/nginx/html && nginx -g daemon off; )"
fi

Answer 1

1. 检查目录（/app）是否创建。如果没有，请在 cfg 文件中使用以下语句并授予该目录的权限

RUN mkdir -p /app

RUN chmod -R 777 /app

2. 还在入口点脚本中授予权限

#!/bin/sh
set -e

chmod -R 777 /app

if [ "$1" = 'uat' ]; then
    "$(cp /app/uat/env.js /usr/share/nginx/html && nginx -g daemon off;)"
elif [ "$1" = 'prod' ]; then
    "$(cp /app/prod/env.js /usr/share/nginx/html && nginx -g daemon off; )"
fi

3. 为了使容器启动，请在入口点脚本中使用无限循环，并将其复制到相应的位置并重新启动容器，然后可以进行调试

入口点脚本：

#!/bin/sh
while true; do sleep 120; done

复制命令：

docker cp <entry point script path> <container_name>:<path to copy the script in container>

docker restart <container_name>
