Introduction

Welcome 👋 to this blog. If you want to learn about Docker and are a beginner, you have come to the right place. This blog series will cover everything from the very beginning to the end. This blog will teach us about the necessary and important Docker commands.

List of commands

List the containers that are actively running 

$ docker ps

Note: If the Docker commands are not running in your system, it is not installed or does not have enough privileges to use it with sudo commands.

List all the containers irrespective of their running status 

$ docker ps -all

Run a Docker container

Step 1: Create a container

$ docker container create hello-world:linux

Here, hello-world:linux is a hello world container image which is pulled from the docker hub

Step 2: Start the container

$ docker container start <Container ID>

Here, is the container ID which can be obtained by running the previous commands docker ps.

Running the Docker container(short way) 

$ docker run hello-world:linux

docker run = docker container create + docker container start + docker container attach

Getting the log of the container 

$ docker log <Container ID>

Run additional commands from the container 

$ docker exec <Conatiner ID> <Commands>

Starting a interactive shell 

$ docker exec --interactive --tty <Container ID>

Stop the container immediately 

$ docker stop -t <ID>

Remove the container 

$ docker rm <Container ID>

List all the docker image 

$ docker images

Remove the Docker image 

$ docker rmi <Image ID>

Remove the Docker Image forcefully 

$ docker rmi -f <Image ID>

Binding ports to the container 

$ docker run -p 5001:5000 our-server

Tagging the image name 

$ docker tag <Local-image-name> username/your-image-name:0.0.01

Conclusion

In this blog, we explored different commands of Docker containers, images, emphasising their roles in container & image creation. In the next blog, we will delve deeper into the technical aspects. Stay tuned
