睡眠在 docker-compose 命令上不起作用，失败 5 次

Question

我有一个高山图像。我正在尝试在我的 docker-compose 命令行上睡觉(用于测试一些东西(。但是这样做：

命令：睡眠 30 秒 &&NODE_ENV=生产节点应用.js

给我错误：

thesailsapp_1  | sleep: invalid number '&&'
thesailsapp_1  | sleep: invalid number '&&'
thesailsapp_1  | sleep: invalid number '&&'
thesailsapp_1  | sleep: invalid number '&&'
thesailsapp_1  | sleep: invalid number '&&'
nginx-certbot_thesailsapp_1 exited with code 1

有谁知道如何解决这个问题？有谁知道为什么它错误 5 次而不是一次？(在这里学习码头工人(

这是我的完整 docker 撰写文件：

version: '3'
services:
thesailsapp:
image: noitidart/private-container:thesailsapp
restart: always
environment:
- sails_log__level=silly
command: sleep 30s && NODE_ENV=production node app.js
nginx:
image: nginx:1.15-alpine
restart: always
volumes:
- ./data/nginx:/etc/nginx/conf.d
- ./data/certbot/conf:/etc/letsencrypt
- ./data/certbot/www:/var/www/certbot
ports:
- 80:80
- 443:443
command: "/bin/sh -c 'while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g "daemon off;"'"
certbot:
image: certbot/certbot
restart: always
volumes:
- ./data/certbot/conf:/etc/letsencrypt
- ./data/certbot/www:/var/www/certbot
entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"

这是我的码头工人文件：

# Start with a node 8.16 slim image to keep the container size down
FROM node:12-alpine
# Specify a default directory for where our app will be placed within the container.
#
# This can be overridden with docker build --build-arg WORKDIR=some-dir/ .
# Always append the directory name with a /
ARG WORKDIR=/opt/apps/thesailsapp/
# Create a directory to contain our application
RUN mkdir -p $WORKDIR
# Switch default working directory to our new directory
WORKDIR $WORKDIR
# Copy our package and lock files over first,
# as the build can then cache this step seperately from our code.
#
# This allows us to build faster when we only have code changes,
# as the install step will be loaded from cache,
# and rebuilt when package files change
COPY package.json package-lock.json $WORKDIR
# Set NODE_ENV=development as i need the webpack dev files
# Install all deps, including development deps, as that is needed
# for the webpack build phase. Uninstall puppeteer first though,
# that's a massive install and not used for building.
RUN NODE_ENV=production npm i
# Now copy over your actual source code
#
# REMEMBER: We are ignoring node_modules in the .dockerignore file explicitly,
# so docker will not copy over that directory. The app will use th modules installed above.
COPY . $WORKDIR
# Build frontend production assets
RUN NODE_ENV=production npx webpack --config webpack.config.js
EXPOSE 1337
### why is npm start here? this should only happen on the droplet instance
# Set the default CMD to run when starting this image.
#
# You can easily override this when running the image
CMD npm start

docker-compose.yml文件中的command应该是单个命令。如果需要多个命令，则单个命令可以是将实际命令作为参数的 shell。

command: sh -c "sleep 30s && NODE_ENV=production node app.js"

您已经在多个其他地方执行此操作，所以我猜该结构很熟悉。
