www.coachdevop...
Create Jenkins pipeline for the following:
- Automating builds
- Automating Docker image creation
- Automating Docker image upload into DockerHub
- Automating Docker container provisioning
Bitbucket URL is - bitbucket.org/...
Pre-requisites:
1. Jenkins is up and running
2. Docker installed on Jenkins instance and configured.
3. Docker plug-in installed in Jenkins
4. user account setup in cloud.docker.com
5. port 8096 is opened up in firewall rules.
Step #1 - Create Credentials for Docker Hub
Step # 2 - Create a pipeline in Jenkins, name can be anything
Step # 3 - Write the pipeline code
Step # 4 - Click on Build - Build the pipeline

Very nice ..well organized video..really commendable.

[@DevOpsCoach]

Thank you so much for your kind words, it means a lot to me

[@sonalivarshney198]

1 question please.. How do we know that when we have to give credentials in manage jenkins-> credentials. Bcz in previous video for tomcat u gave credentials in snippet generator but for Docker hub u r saving the credential in manage jenkins.. 2) for maven you gave maven home path in global tool configuration but for Docker why you didn't give? I am having this confusion a lot

[@HarshSharma-qo6ew]

How can we run image in to another remote host.. Using jenkins

[@shikharshah1826]

Huge thanks for the content! Quick question: How do we run the docker build and all commands in a jenkins instance that's already running on a docker container? I tried DIND but somehow I'm failing

[@DevOpsCoach]

You need to install docker in Jenkins instance and also docker plug-in in Jenkins as well, please check the pre-requisites

I'm trying to follow this tutorial locally, have the docker plugins configured and Jenkins locally, docker desktop up and running on my MacOS but when I execute the pipeline I get the error=> docker: command not found

[@DevOpsCoach]

you need to install Docker locally too!

[@sanjeevreddy3691]

in real time how and on what basis we give version to docker image while building

[@rishabagarwal7295]

How can we define the image name how can I get i am confused bit here

[@tufisii2006]

I have Jenkins installed but in a Docker container. How do we run the docker build and all commands in a jenkins instance that's already running on a docker container? In your example you got Jenkins installed on EC2 directly. But what if the EC2 had Docker installed and you install Jenkins in a container?

[@abhinavbrs3882]

I need to work with this exact scenario, please let me know how to if you have figured it out

[@tufisii2006]

@@abhinavbrs3882 Hello! I solved the problem. Jenkins works with Agents in order to run comands. It has an internal agent by default but it is not recommended to use it. You need to run another EC2 instance (or any server that can be accessed with internet) and add it as a Jenkins agent. Search on KZbin:” how to add Jenkins agent node” . After the setup will be done all the commands will be run on the agent. So if you want to run:”docker pull X” you need to install docker on the new server

[@architjain9346]

So nicely explained....... thanks you so much I have a question sir.. how did you create docker image as it requires dockerfile. basically I didn't get the create image stage

[@DevOpsCoach]

Dockerfile was already part of my code. I created docker image using Docker image build stage

[@nsontung]

Love your video, one question is: Can I do the same thing for the freestyle project? deploy the image to nexus and pull it back to deploy!

[@DevOpsCoach]

Yes you can! you will have to use execute shell to execute shell script

[@shahul.hameed.m]

Let's say we have many pipelines, then how should we know that which pipeline is to access which credentials? I want to know that for every differnt pipeline we use different dockerhub credentials.?

[@DevOpsCoach]

You will be using credentials id which should be unique

[@skateforlife3679]

What is the creditentials ? Where does it come from ? I made a docker hub credit but it says that it is not matching when i build the pipeline

[@DevOpsCoach]

you need to create account in cloud.docker.com and then use these login info to create credentials entry in Jenkins

[@skateforlife3679]

@@DevOpsCoach Sorry, i understood after, it's nice thankjs !

[@anuradhatalla8732]

What type of language you have used inside script { } And Can we use any coding language to create pipeline in jenkins

[@DevOpsCoach]

groovy scripting

[@atexnik]

1:14 EXPOSE doesn't tell the app which port to listen, it is a pure documentational instruction, and is used with -P option for docker run.

[@jothimanikandanofficial3690]

I was facing some error /var/jenkins_home/workspace/Newproje........: docker: not found

[@DevOpsCoach]

Install docker in Jenkins ec2 instance

Hi bro i having one doubt how I would contact you

[@bluesteel1]

how to pull docker containers from docker hub in jenkins?

[@DevOpsCoach]

dockerhub stores only images, not container. images can be pulled using docker pull command. you can execute it Jenkins pipeline --> sh 'docker pull '

[@deva_2022]

After this next video link add in description. Next step .

[@DevOpsCoach]

done, thank you!

[@LEOxLCU]

sir, this is what am searching too far

So, in order to keep the webpage alive for 24x7 what is the procedure they do in organization if server goes down ?

[@DevOpsCoach]

setup cluster and add more than one servers. there are a lot of ways to make your application highly available
