Notes taken from A Cloud Guru course titled “Docker Certified Associate (DCA)” by Will Boyd.

Docker Inspect

Allows to get information about Docker objects, e.g. containers, images, services, etc.

Few Inspect Command Examples

# Run a container and inspect it.
docker run -d --name nginx nginx
docker inspect <CONTAINER_ID>

# List the containers and images to get their IDs, then inspect an image.
docker container ls
docker image ls
docker inspect <IMAGE_ID>

# Create and inspect a service.
docker service create --name nginx-svc nginx
docker service ls
docker inspect <SERVICE_ID>
docker inspect nginx-svc

# Use the type-specific commands to inspect objects.
docker container inspect nginx
docker service inspect nginx-svc

# Use the --format flag to retrieve a subset of the data in a specific format.
docker service inspect --format='{{.ID}}' nginx-svc
