Build .jar and docker with Jenkinsfile pipeline

We may create a docker with Spring Boot very easy ... Here some examples of jenkinsfile.

First at all, let's create a Jenkins Job Pipeline.

Jenkins Pipeline (or simply "Pipeline") is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins.

A continuous delivery pipeline is an automated expression of your process for getting software from version control right through to your users and customers.

Declarative Pipeline for Maven Projects

Using a Jenkinsfile to manage credentials

DockerHub credentials: logging in with your password grants your terminal complete access to your account.

For better security, log in with a limited-privilege personal access token. Learn more at https://docs.docker.com/go/access-tokens/

jenkinsfile build example: #20 to #57

job Test3: ouput file and jenkinsfile

#20

Be careful: this jenkinsfile does NOT work!!!

We must debug the output file to find mistakes in our pipeline ...

#23

Here you can check the right file and the mistake corrected

Error from build 20 has been corrected

There is a error to check: push docker to dockerhub.

Dockerhub webhook

We can use webhooks to cause an action in another service in response to a push event in the repository. Webhooks are POST requests sent to a URL you define in Docker Hub.
