Thank you, very thorough tutorial. One line that you mention, "Running an image creates a container" was easy to miss... I was struggling to think of how running an image was different than running a container. I rewound, and caught your explanation. It makes sense now.

4:00 How big are these images? The iso of ubuntu 18.04 LTS is almost 2 gigabytes. So, I assume what you're downloading is not all of ubuntu, but some much smaller version. Otherwise, this could be very slow and take up a lot of HDD space to simply run an image.

[@RaghavPal]

Yes, you can check the documentation for more details

[@ManuelJordan317]

Hello - as usual, huge thanks for this video - I have a situation at 05:50 - I have docker community 20.10.17 for Linux - I tried the command with many images running as containers, two images based on "latest" - only one of them "running", other images with tags, some running and others not as containers - the point is that the mentioned command with - dangling=false" - always return *all* the images (so description shown in yellow below seems not correct) perhaps something has changed? - I expected to see all the images with "latest" and other with tags with zero containers associated. BTW with dangling=true" returns always empty as your side too - Thanks I did realize it is valid - dangling=true - if the image has "REPOSITORY" and "TAG" as '' - shown through 'docker images' - it happens if your have an image with at least one container running - for example through 'docker run -it alpine:3.16' and in other tab you execute 'docker rmi -f alpine:3.16' - the container is NOT removed but NEITHER the image, it appears yet through 'docker images' but with the two mentioned headers with '' - therefore now is clear the difference between dangling=false and dangling=true Again thanks for the video - highly valuable!

Hi Raghav, thanks for the wonderful vidoes. your video makes it easy for beginners to learn with simple and easy explanations. I have a question regarding "dangling=true/false". as per your video lesson "dangling=false", it should show only images that are not associated with any running containers. But in my case, I notice that with "docker ps", I have container based on this the image and it also shows in the output of "dangling=false". I am a little big confused. Also the notes in docker says "dangling" is used to filter untagged images. I would appreciate your clarification in this regard.

[@abhilashkokkonda1713]

Hi Raghav..What is the difference between image and a container?

[@RaghavPal]

Hi Abhilash, Image is a set of layers. Containers are running instances of images. So when you start (run) image you have a running container. Also see this : stackoverflow.com/questions/21498832/in-docker-whats-the-difference-between-a-container-and-an-image stackoverflow.com/questions/23735149/what-is-the-difference-between-a-docker-image-and-a-container/45598098

So just like a java class can have multiple instances (objects), a Docker image can spin up multiple containers?

Yes, you can use a image to create multiple containers

[@pratik6447]

What is ubuntu image? Is it ubuntu software or a project? I didn't get it clearly what is an image?

[@RaghavPal]

Hi Pratik, look at image like this. Support you have a dev project using multiple libraries, configurations, settings etc. You create a docker file to put all this together (watch dockerfile video) and then this can be used to create a docker image. So docker image will be like a template for your project and running this image will create a docker container with all the settings & configurations for your project. Now similarly Ubuntu image is a template that contains all settings, configurations, commands to setup an ubuntu system inside a docker container

[@epajarjestys9981]

I think the question is "How does the authentication happen in the Ubuntu instance in Docker?" It seems when running the Docker Ubuntu image, the user is automatically logged in as root. The question is: How does this happen? I am also new to Docker, so I am not sure about the answer. But I know this: The Docker container engine always runs in a Linux environment (if your host system is Linux, then it uses your host system directly, otherwise the Linux environment for the container engine runs in a virtual machine), and in previous versions, Docker containers were implemented as LXC containers (and even earlier as chroots). It seems the "logged in as root by default" thing is a thing there as well: (askubuntu.com/questions/932976/what-are-root-and-ubuntu-password-in-lxc-ubuntu16-04-container). But I don't know more about the why and how. Note: In current version, Docker does not use LXC anymore, but its own library for the container engine: (github.com/docker/libcontainer). But maybe this is at least a hint to find more info.

Running this command in Windows gave error. docker run -it busybox bash docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown.

[@RaghavPal]

Varun The error message you encountered while running the `docker run -it busybox bash` command indicates that the `bash` executable was not found within the busybox container. Let's explore why this happened and how to resolve it. 1. Busybox and Minimal Images: - Busybox is a lightweight, minimal Linux distribution that provides a set of common Unix utilities in a single binary. It is often used in Docker containers to reduce image size. - However, busybox does not include all the standard utilities found in a typical Linux distribution. It only includes a minimal set of essential commands. 2. No Bash in Busybox: - The error message you received indicates that the busybox container does not have the bash shell installed. - When you run `docker run -it busybox bash`, Docker tries to execute the bash shell inside the container, but it cannot find the bash binary. 3. Alternative Solutions: - To resolve this issue, consider the following alternatives: - Use the Default Shell: - Instead of explicitly specifying bash, use the default shell provided by busybox. You can run: ``` docker run -it busybox sh ``` - This will start an interactive shell session using the sh (Almquist Shell) provided by busybox. - Install Bash: - If you specifically need bash, you can create your own custom Docker image based on busybox and install bash inside it. - Create a Dockerfile with the following content: ```Dockerfile FROM busybox RUN opkg update && opkg install bash CMD ["bash"] ``` - Build the image: ``` docker build -t my-busybox-with-bash . ``` - Run the container: ``` docker run -it my-busybox-with-bash ``` 4. Architecture Considerations: - Ensure that the architecture of the Docker image matches your host system. For example, if you're running Docker on an x86_64 system, make sure you're using a 64-bit image. - Some images, including busybox, may not work on architectures other than x86_64. Remember that busybox is designed to be minimal, so it lacks certain features found in full-fledged Linux distributions. --

How to create an image, push and reuse it. Especially how to configure an image.

[@RaghavPal]

Hi Bhargav, I will try to add more examples to docker image, For now you can refer here docs.docker.com/engine/reference/commandline/image/

[@matthewperez7780]

i am probably dumb but i still don't really understand the concept of an image fully. Like what is an image, why is it called an image? what are they for? it was a great tutorial on how it is done and clear explanations on all commands but i can't fully understand what i would use it for, like it's funtions etc.. i am learning about Iaas, Paas, Saas, Faas but i can't get this "image" concept through my head :(

[@crazymalady6180]

What's the importance of a docker image? if you'll explain it in a nontechnical person?
