[Docker] How to Inspect Docker Containers

To inspect Docker containers and retrieve detailed information about them, follow these steps:

Step 1: Run the Container

First, ensure the container you want to inspect is running. If it is not already running, you can start it with the following command:

  docker container run -d --name nginx nginx

Step 2: Inspect the Container

Next, use the docker container inspect command to get detailed information about the container. This can be done using either the container name or ID:

docker container inspect nginx

Step 3: Filter Specific Information

To retrieve specific information, such as the state of the container, use the -f or --filter parameter with the Go template syntax. For example, to get the state information in a nicely formatted JSON, use:

docker container inspect -f "{{json .State}}" nginx | jq .

By following these steps, you can easily inspect Docker containers and extract detailed information about their state and configuration.
