How to create a container in Docker?
Step 1: Pull the mirror
Before creating the container, you need to pull the image you want to run. Use the following command:
<code>docker pull [镜像名]</code>
For example:
<code>docker pull nginx</code>
Step 2: Create a container
Use the docker run command to create a container:
<code>docker run [选项] [镜像名] [命令]</code>
Common options:
- -i, --interactive: Keep the container in interactive mode at runtime.
- -t, --tty: Allocate a pseudo-terminal.
- --name: Specify a name for the container.
- -p: Port mapping, map container ports to host ports.
For example, create an interactive Nginx container named "my-nginx" and map container port 80 to host port 8080:
<code>docker run -it --name my-nginx -p 8080:80 nginx</code>
Step 3: Start the container
After creating the container, you can start it with the docker start command:
<code>docker start [容器名]</code>
For example:
<code>docker start my-nginx</code>
Other commands:
- docker attach [Container name]: Attach to the running container.
- docker stop [Container name]: Stop the container.
- docker rm [Container name]: delete the container.

Apr 15, 2025 am 11:21 AM
Troubleshooting steps for failed Docker image build: Check Dockerfile syntax and dependency version. Check if the build context contains the required source code and dependencies. View the build log for error details. Use the --target option to build a hierarchical phase to identify failure points. Make sure to use the latest version of Docker engine. Build the image with --t [image-name]:debug mode to debug the problem. Check disk space and make sure it is sufficient. Disable SELinux to prevent interference with the build process. Ask community platforms for help, provide Dockerfiles and build log descriptions for more specific suggestions.
