Use project version as docker image tag

Alexander Hofmeister

Hi everyone! 

I have following configuration which builds and pushes my project as image into dockerhub

pipelines:
 branches:
  master:
   - step:
      services:
       - docker
      script: 
       - mvn clean install
       - export IMAGE_NAME=org/project:$BITBUCKET_COMMIT 
       - docker build -t $IMAGE_NAME .
       - docker login --username $DOCKER_HUB_USERNAME --password $DOCKER_HUB_PASSWORD
       - docker push $IMAGE_NAME

 

This works fine and was easy to setup. Now, I want to tag my images with the current version of my project, which is specified in the *pom.xml* which lies in the root directory. 

How can I read/extract/store the version of my project and use it as tag for a docker image?

 

Cheers,

Alexander

Please have a look at below if it could help you.

```

export VERSION=$(awk 'FNR==5' pom.xml)

```

it will export 5th line of the file.

 

```

docker build -t $IMAGE_NAME:VERSION .
