docker images

# Pull Docker image from Docker Hub

docker pull viharireddy18/mynginx:v1

# Run Docker Container

docker run --name <CONTAINER-NAME> -p <HOST_PORT>:<CONTAINER_PORT> -d <IMAGE_NAME>:<TAG>

# Example using Docker Hub image:

docker run --name myapp1 -p 8080:80 -d stacksimplify/mynginx:v1

# List only running containers

docker ps

# List all containers (including stopped ones)

docker ps -a

# List only container IDs

docker ps -q

docker exec -it <container-name> /bin/bash

# Example:

docker exec -it myapp1 /bin/sh

# Inside the container, you can run commands:

ls
hostname

# Execute commands directly

# List directory contents inside the container

docker exec -it myapp1 ls

# Get the hostname of the container

docker exec -it myapp1 hostname

# Print environment variables

docker exec -it myapp1 printenv

# Check disk space usage

docker exec -it myapp1 df -h

# stop a running container

docker stop <container-name>
docker ps
docker ps -a
docker start <container-name>

# Stop the container if it's still running

docker stop <CONTAINER-NAME>

# Remove the container

docker rm <CONTAINER-NAME>

# Or stop and remove the container in one command

docker rm -f <CONTAINER-NAME>

docker images
docker rmi <IMAGE-ID>
docker rmi <IMAGE-NAME>:<IMAGE-TAG>

docker version

# Log in and Log out to Docker Hub

docker login
docker logout

# Run the default Nginx Docker Image

docker run --name <CONTAINER-NAME> -p <HOST_PORT>:<CONTAINER_PORT> -d <IMAGE_NAME>:<TAG>

docker ps

# Stop and remove the Docker container

docker stop myapp1
docker rm myapp1

# Or force remove the container

docker rm -f myapp1

# Tag the Docker image

docker tag mynginx-custom:v1 YOUR_DOCKER_USERNAME/mynginx-custom:v1

# Push the Docker image to Docker Hub

docker push YOUR_DOCKER_USERNAME/mynginx-custom:v1

# Search for 'nginx' images

docker search nginx

# Limit the search results to 5

docker search nginx --limit 5

# Filter search results by stars (e.g., images with at least 50 stars)

docker search --filter=stars=50 nginx

# Filter for official images only

docker search --filter=is-official=true nginx

## Inspect commands in Docker

# Inspect the Docker image

docker image inspect [IMAGE-NAME]:[IMAGE-TAG]

# Example:

docker image inspect demo4-dockerfile-labels:v1

# Get the creation date of the Docker image

docker inspect --format='{{.Created}}' [IMAGE-NAME]:[IMAGE-TAG]

# Example:

docker inspect --format='{{.Created}}' demo4-dockerfile-labels:v1

# Get the Docker image labels (unformatted)

docker inspect --format='{{json .Config.Labels}}' [IMAGE-NAME]:[IMAGE-TAG]

# Example:

docker image inspect --format='{{json .Config.Labels}}' demo4-dockerfile-labels:v1

# Get the Docker image labels (formatted with jq)

docker image inspect --format='{{json .Config.Labels}}' [IMAGE-NAME]:[IMAGE-TAG] | jq

# Example:

docker image inspect --format='{{json .Config.Labels}}' demo4-dockerfile-labels:v1 | jq

# Stop and remove the container

docker rm -f mylabels-demo

# List Docker Images to confirm removal

docker images

# List Static Files from Docker Container

docker exec -it my-add-vs-copy-demo ls -lrta /usr/share/nginx/html
