How to Tag, Push and Pull docker images on Docker Hub

[Music] thank you hi guys welcome to simplifying Tekken programming so in today's session we are going to check how we can tag the docker images then how we can push the docker images to Docker Hub and how we can pull that image from Docker Hub to our local machine and how we can run it that image on the local system okay so this is a common workflow so we have a input as a like application runnable file so we can choose any language like currently we are developing applications via spring boot so we have to create application via spring boot spring boot jar file then we have to add the docker configuration via Docker file that is the docker image and like a application running command okay so build that application by using Docker file and whatever the image that is created so that image we can push to Docker Hub so Docker Hub is like a platform like similar to GitHub where like we can store multiple images or our images into some particular cloud storage or something like that okay so we have to we can push the images through Docker Hub then whenever required so we can pull the same image or we can pull the available images from the docker Hub and then we can run into our local system via like a Docker container so this we are going to see so moving further like uh we we can see one more diagram where like we have divided this into like our according to the environments so like this Docker file is a project source code then we can gonna build that source code and convert that our project runable file into Docker image and then this Docker image supported by Docker container on top of virtual machine and we we can like push this Docker images through Docker Hub then wire Docker Hub like we can create multiple containers according to our environments so that is the tab uat and production or a staging environment that is uat environment or we can create the cob environmental that is like a backup of production server so this way like a Docker this is a Docker particular use case where like we can use this application as per our environment so let's start the practicals so first we need our Docker Hub to be running on our local machine so we in previous sessions like we have covered like how to install Docker desktop and how we can create get the spring boot application by using Docker okay so we can start this Docker desktop so like you are looking for how to install the docker on Windows system then you can refer like a rare videos like link is provided at the top right corner okay so our Docker desktop is starting so so meanwhile like we can understand this application flow like where in previous session so we have created a spring boot Docker Docker image by using open jdk so we we are taking the base example from there and we are like using that image to push that image into Docker hub and then again we will pull and we will run this into the Container okay so our Docker is starting so meanwhile like we can create the docker Hub account so go to your favorite browser and go to Docker Hub so in order to like use Docker Hub we need to create our account so go to hub.docker.com okay so this is the docker Hub homepage so here except our cookies then getting started today for free okay so click here on register okay so here it is popping up create Docker account so put the username so I am putting username as a simplifying tag okay and then put the email okay give the password go to sign up okay so our account is created so it is asking for login so put your username thank you okay so we have logged in as a simplifying tag so now it is asking for this so we don't need to worry about this so just we have to continue as a free okay so meanwhile let's see if Docker desktop is started yeah so Docker desktop is started so now uh like we can choose our local image so go to CMD okay so our Command Prompt is open now so let's verify if Docker is running so Docker minus minus version so we have Docker version so now let's see what all images are there into our system so let's say give command as a Docker and images okay so here we can see the spring boot Docker jar that we have created earlier and then we have Hello World also so we will use this springboard Docker jar so so first like we have to log into our Docker hub uh account so we have created we have already created Docker account so it is asking to verify your email address so go to your email address and verify it okay okay so our Docker Hub account is verified now so now let's login to Docker house a Docker and then login okay so it is asking username so give username new password also Okay so okay so we have to re-enter so docker no give username in small case okay so our login is succeeded so now uh just we need to tag this image uh with your Docker Hub username okay so here like just we have to mention Docker tag and this to this with your username okay so this tag is basically so we suppose we want to create multiple images as per environments so by using this stack like we can clone our application or we can use this naming convention to identify our application okay let's say enter yeah so our tag is created so now we just need to push the images to Docker Hub So currently in the docker Hub we don't have anything so let's push the image so let's say docker push this image that's it that's enter yeah so it will take time according to your network speeds so you have to wait until it is finished with uploading a little longer than a few minutes later okay so our Docker images is pushed so If You observe like it it is retried because it has got time out because this file size is like a 321 MB so if you got time mode so please try again so keep trying so it will get success okay so in my case it is uploaded let's verify on the browser foreign like in the repositories so we have simplifying Tech uh springboot docker.charge so last pushed three minutes ago okay so now let's click on this okay so you can see this tag is latest then type image in three minutes ago okay so now what we can do so we can pull this image down so this is Docker command for pushing this uh file so now we have to pull this image okay so you you can see this Docker pull command is there so copy this it is simple just Docker pull and whatever the image or tag name okay so go here before that like we have to remove this so Docker images okay so we have to remove the existing one first so let's say docker RMI or the image name okay so this is the attack now so let's verify it again say Docker images so you can see that tag is gone now so now just uh execute this command so we want to pull this Docker image so Docker pull and a simplifying Tech springboard Docker dot chart so let's enter okay so our foolish success download a newer version of image so let's verify it say blocker images so you can see it is a again it is downloaded so previously it is not listed so again it is downloaded so now uh just we have to run this so we pulled this image into our local system so we have to run it now so docker run minus P provide the port number 8080 so this is like a Docker port number this is application port number and whatever this image name okay let's enter oh invalid prototype oh Church okay so we have to just add the colon yeah so you can see the our application is getting started so spring boot application is starting up okay so our Tomcat is started on port 8080 and our application is also a springboard Docker application is also started so now let's run our application let's go here so type localhost colon 8080 and our arrest API endpoint is like hello docker hello dear Center okay so we got welcome to Docker application by simplifying Tech so our full image is get a success and we are able to run this image okay so this way we can able to push the images into Docker Hub we can able to pull the images and we can able to run this image into our container so it depends on a particular environment also so if you want to yeah so we can create for multiple environments like we can create staging environment production environment and whatever the additional environment you want okay so this way like by using Docker Hub we can able to run the spring boot application or any Docker based application okay so thanks a lot for watching so stay tuned for further interesting sessions and please subscribe the channel thanks a lot [Music]
