While building and pushing an image to the docker registry, one can encounter the following error:

Resolution

The resolution is to add an environment stage variable named “container” with a value “docker”.
Follow these simple steps to do add a stage variable:

• Navigate to Variable on the left side of the pipeline studio.You can refer to the below screenshot for the reference.
  

  

• Go to the stage where the Build and Push an Image to Docker Registry step is added.

• Go to stage variable → Add variable.

• Write variable name as container and type will be string and then select Save.

• Give the value of the variable as docker.
  

  

• Click on Apply Changes.
