## Use your Docker Build and Run Knowledge

**docker build -** you can use `sh 'docker build . -t <tag>'` in your pipeline stage block to run the docker build command. (Make sure you have docker installed with correct permissions.

**docker run:** you can use `sh 'docker run -d <image>'` in your pipeline stage block to build the container.

**How will the stages look**

### **Task 1:**

1. Create a docker-integrated Jenkins declarative pipeline
    
2. Use the above-given syntax using sh inside the stage block
    
3. You will face errors in case of running a job twice, as the docker container will be already created, so for that do task 2
    

* **Step1:** Create a new pipeline project and named it node declarative

    *Step2:*\- Now in the "Project Configuration" section, we have to define a pipeline script in the definition.

    Step4:-Once the build is completed we can check in the Console Output. We can see the pipeline is successful.
    
    Step5:-Now you check the multi-stage view by clicking on the “Full Stage View” on the project main page

    ### **Task 2:**
    
    * Create a docker-integrated Jenkins declarative pipeline using the docker groovy syntax inside the stage block.
        
    * You won't face errors, you can Follow **this documentation**
        
    * Complete your previous projects using this Declarative pipeline approach
        
        **Step1:-**Now we have to add a docker image in the Build stage

        Step2:-Click on Save and then click on Build Now.
