How to deploy your own project using docker?
A while ago, the company had a need to deploy the project to the local privatization. I didn't study the server and it was very laborious to build it, so I used docker to make a series of images of project privatization deployment. Now I write a blog to record the process of learning and building.
Take my current project for example, which is divided into front-end (vue Implementation), back-end (PHP laravel framework), OnlineJudge (online problem judgment), and data layer and cache (mysql, redis). The idea is to first create an image for each project, upload it to the docker hub, and then use docker compose for one click deployment
Create a mirror for the Laravel project
- Enter the project directory and create a dockerfile file with the following contents
FROM php:7.4-fpm
RUN sed -i 's/deb.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list && \
sed -i 's/security.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list && \
sed -i 's/security-cdn.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list
RUN sed -i 's/9000/\/run\/php\/php7.4-fpm.sock/' /usr/local/etc/php-fpm.d/zz-docker.conf
RUN mkdir /run/php \
&& touch /run/php/php7.4-fpm.sock \
&& chmod 777 /run/php/php7.4-fpm.sock \
&& chmod +s /run/php/php7.4-fpm.sock
#### install PHP extend ######################
RUN pecl install redis-5.1.1 && \
docker-php-ext-enable redis
RUN docker-php-ext-install pdo && \
docker-php-ext-install pdo_mysql && \
docker-php-ext-enable pdo pdo_mysql
#### install nginx and supervisor extend ######################
RUN apt-get update -yqq && \
apt-get install -yqq \
nginx supervisor cron
RUN echo "* * * * * cd /var/www/kaoshi.web.server && php artisan schedule:run >> /dev/null 2>&1" >> /etc/crontab
#### Copy profile to mirror ######################
COPY ./ /var/www/kaoshi.web.server/
COPY ./php-fpm/www.conf /usr/local/etc/php-fpm.d/
COPY ./sites/default /etc/nginx/sites-enabled/
COPY ./supervisor.conf /etc/supervisor/conf.d/
###### modify laravel Various configurations of the project #########################
RUN chown -R www-data:www-data /var/www/kaoshi.web.server \
&& mv /var/www/kaoshi.web.server/.env.docker /var/www/kaoshi.web.server/.env
ENV MYSQL_HOST=127.0.0.1
ENV MYSQL_DATABASE=exam
ENV MYSQL_USER=root
ENV MYSQL_PASSWORD=root
ENV REDIS_HOST=127.0.0.1
ENV REDIS_PORT=6379
ENV JUDGE_SERVER_HOST=kaoshi_judge_server
ENV JUDGE_SERVER_PORT=8080
WORKDIR /var/www/kaoshi.web.server
ADD ./startup.sh /opt/startup.sh
RUN sed -i 's/\r//g' /opt/startup.sh
CMD ["/bin/bash", "/opt/startup.sh"]
EXPOSE 80
This file is relatively long. The general construction idea is based on php7.4 image. Switch apt get source - > install PHP extension - > install nginx and other required extensions - > copy various configuration files in the project directory - > set startup script - > set exposed port number.
Here, you need to use the ENV command to set various configurations of laravel, because these configurations can be freely modified when creating containers in docker compose later
- Write the startup script file. I started supervisor and crond additionally because the queue service is needed`
#!/bin/bash
sed -i "s/MYSQL_HOST/${MYSQL_HOST}/" /var/www/kaoshi.web.server/.env &&
sed -i "s/MYSQL_DATABASE/${MYSQL_DATABASE}/" /var/www/kaoshi.web.server/.env &&
sed -i "s/MYSQL_USER/${MYSQL_USER}/" /var/www/kaoshi.web.server/.env &&
sed -i "s/MYSQL_PASSWORD/${MYSQL_PASSWORD}/" /var/www/kaoshi.web.server/.env &&
sed -i "s/MYSQL_USER/${MYSQL_USER}/" /var/www/kaoshi.web.server/.env &&
sed -i "s/MY_REDIS_HOST/${REDIS_HOST}/" /var/www/kaoshi.web.server/.env &&
sed -i "s/MY_REDIS_PORT/${REDIS_PORT}/" /var/www/kaoshi.web.server/.env
supervisord -c /etc/supervisor/supervisord.conf
supervisorctl start all
# Start php-fpm cron in background
php-fpm -D
/etc/init.d/cron start
# Start nginx in foreground
nginx -g "daemon off;"
- Build image and upload
Preparatory work: Here you need to have a docker account. After passing the authentication, the constructed image is uploaded to your own image library.
Enter the project directory and execute the build command
> docker build -t youdockerid:backend_server ./
There are two ways to upload. You can directly use docker to log in and upload, or docker push can be very simple.
Foreground project construction image
The construction process is basically similar to the file, but the specific configuration is different. It can also be uploaded after the construction is completed
dockerfile:
FROM node:16.3
RUN sed -i 's/deb.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list && \
sed -i 's/security.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list && \
sed -i 's/security-cdn.debian.org/mirrors.aliyun.com/' /etc/apt/sources.list
RUN npm config set registry https://registry.npm.taobao.org

Write docker compose one click deployment
- First, create a new directory as the deployment directory. The directory structure is as follows
├── .env //configuration file
├── .env.example
├── data //The data of mysql or redis or other modules are stored here
│ ├── mysql
│ └── redis
│ └── appendonly.aof
├── docker-compose.yml //Deployment file
└── initdb.d //Database initialization file
└── init.sql
docker-compose.yml:
version: '3.5'

backend:
driver: bridge

When you're done, you can happily build:
> docker-composer up -d Starting mysql_server ... done Starting redis_server ... done Starting frontend_server ... done Starting backend_server ... done
be accomplished!
