Restarting the docker service will have an impact on the container. After restarting the docker service, the container will stop running; because after restarting the docker service, all docker containers running on this server will exit and will not start with docker startup.

Will restarting the docker service affect the container?

The operating environment of this tutorial: linux5.9.8 system, docker-1.13.1 version, Dell G3 computer.

Restarting the docker service will affect the container.

After docker is restarted, all docker containers running on this server will also exit, that is, the containers will stop running and will not start following docker startup.

You can use docker ps -a to take a look.

So is there any way for us to restart the docker process and let the container start automatically?

There are two ways to set it:

1. The container has not been created yet, add the –restart=always parameter when running the container

docker run -id --restart=always -p 9999:9999 -v xxxx:xxxx 镜像名称:tag

2. If the container is already running, run the following command:

docker update --restart=always 容器名字或者容器ID

If you want it to take effect immediately, restart docker systemctl restart docker, otherwise wait until it restarts next time and it will automatically take effect

Others: If you want to stop automatic startup, Run the following command:

docker update --restart=no 容器名字或者容器ID

Docker on Linux: Applications and Use CasesApr 17, 2025 am 12:10 AM

Docker simplifies application deployment and management on Linux. 1) Docker is a containerized platform that packages applications and their dependencies into lightweight and portable containers. 2) On Linux, Docker uses cgroups and namespaces to implement container isolation and resource management. 3) Basic usages include pulling images and running containers. Advanced usages such as DockerCompose can define multi-container applications. 4) Debug commonly used dockerlogs and dockerexec commands. 5) Performance optimization can reduce the image size through multi-stage construction, and keeping the Dockerfile simple is the best practice.

Docker: Containerizing Applications for Portability and ScalabilityApr 16, 2025 am 12:09 AM

Docker is a Linux container technology-based tool used to package, distribute and run applications to improve application portability and scalability. 1) Dockerbuild and dockerrun commands can be used to build and run Docker containers. 2) DockerCompose is used to define and run multi-container Docker applications to simplify microservice management. 3) Using multi-stage construction can optimize the image size and improve the application startup speed. 4) Viewing container logs is an effective way to debug container problems.

Methods for copying files to external hosts in Docker: Use the docker cp command: Execute docker cp [Options] <Container Path> <Host Path>.
