The docker internal container automatically restarts the configuration.
1. The parameter restart=always is not added when the container is created, which results in that the container fails to start automatically when Docker is restarted.
An example of docker container update-restart=always container name operation is as follows: [root@localhost mnt] # docker ps-aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES46cdfc60b7a6 nginx "nginx-g 'daemon..." About a minute ago Up 42 seconds 80/tcp n379d55a734c26 nginx "nginx-g 'daemon..." About a minute ago Up 42 seconds 80/tcp n2f7b2206c019d nginx "nginx-g 'daemon..." About a minute ago Up 46 seconds 80/tcp N1 [root@localhost mnt] # docker container update-- restart=always n1n1 [root@localhost mnt] # systemctl restart docker [root@localhost mnt] # docker ps-aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES46cdfc60b7a6 nginx "nginx-g' Daemon...

2.docker-compose shuts down or restarts docker while restarting the configuration of container restart always
As we all know, if you start using docker, you need to add-restart=always to achieve this function, while if you use docker-compose, you can add restart: always to the relevant service configuration.
