Docker image for both Ready API and Maven

In my project I have to use Git as SCM and have to run my Ready API project from Gitlab Runner. Now I am after the docker image which I can use to build the project with Maven and should also support Ready API.

 

When I run my Ready API test with Maven locally on my machine it works fine but when I am trying to run from Gitlab runner it is erroring out as “/bin/bash: line 66: mvn: command not found
ERROR: Job failed: command terminated with exit code 1”

 

Please note I used the docker image as “  image: smartbear/ready-api-soapui-testrunner”.

 

Can you please send me some supporting information in this regard, as I am really stuck  ☹
