You can use "docker ps" to find containers in docker.
docker ps: List containers
Syntax
docker ps [OPTIONS]
OPTIONS Description:
-a: Display all containers, including those that are not running.
-f: Filter the displayed content based on conditions.
--format: Specify the template file for the return value.
-l: Display recently created containers.
-n: List the recently created n containers.
--no-trunc: Do not truncate output.
-q: Silent mode, only the container number is displayed.
-s: Display the total file size.
Example:
List all running container information.
runoob@runoob:~$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 09b93464c2f7 nginx:latest "nginx -g 'daemon off" ... 80/tcp, 443/tcp myrunoob 96f7f14e99ab mysql:5.6 "docker-entrypoint.sh" ... 0.0.0.0:3306->3306/tcp mymysql
Output details:
CONTAINER ID: Container ID.
IMAGE: The image used.
COMMAND: The command to run when starting the container.
CREATED: The creation time of the container.
STATUS: Container status.

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 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.

Docker container startup steps: Pull the container image: Run "docker pull [mirror name]". Create a container: Use "docker create [options] [mirror name] [commands and parameters]". Start the container: Execute "docker start [Container name or ID]". Check container status: Verify that the container is running with "docker ps".

The methods to view Docker logs include: using the docker logs command, for example: docker logs CONTAINER_NAME Use the docker exec command to run /bin/sh and view the log file, for example: docker exec -it CONTAINER_NAME /bin/sh ; cat /var/log/CONTAINER_NAME.log Use the docker-compose logs command of Docker Compose, for example: docker-compose -f docker-com

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

Create a container in Docker: 1. Pull the image: docker pull [mirror name] 2. Create a container: docker run [Options] [mirror name] [Command] 3. Start the container: docker start [Container name]

Four ways to exit Docker container: Use Ctrl D in the container terminal Enter exit command in the container terminal Use docker stop <container_name> Command Use docker kill <container_name> command in the host terminal (force exit)

Methods for copying files to external hosts in Docker: Use the docker cp command: Execute docker cp [Options] <Container Path> <Host Path>. Using data volumes: Create a directory on the host, and use the -v parameter to mount the directory into the container when creating the container to achieve bidirectional file synchronization.
