Please install docker and docker-compose in advance and configure image acceleration yourself. Note in advance: My entire project was actually built in two parts. During the first deployment, there were only: nginx mysql redis springboot project, and nacos was added later for my own entertainment.
A.docker-compose.yml file

D. Package the springboot project and name it the service name in the configuration
E .Create a folder or file in the corresponding directory
- /root/nginx/html
- /root/nginx/nginx.conf

The final directory structure
docker-compose up -d mysql
F. Since my nacos was added later, you can add the nacos database in the mysql container in advance and then start it (if you don’t have a database, please add it in advance)
Start
docker-compose up
stop
docker-compose down
