Packer docker builder stopping processes running on base image container

[Satwik Mukherjee]

I am using below packer.json file to put war file into tomcat container & build it 

{
  "builders": [{
    "type": "docker",
    "image": "tomcat:8.0",
    "commit": "true"
  }],
  "provisioners": [
    {
    "type": "file",
    "source": "sample.war",
    "destination": "/usr/local/tomcat/webapps/"
    }
   ],
  "post-processors": [
    [
      {
        "type": "docker-tag",
        "repository": "satwikmukherjee/runner-poc",
        "tag": "{{timestamp}}"
      },
      {
        "type": "docker-push",
        "login": "true",
        "login_username": "####",
        "login_password": "####"
      }
    ]
  ]
}

After building while I am running the image committed , within container I am seeing tomcat is not running ,

But while I am doing the same stuff through Dockerfile , no issue found , Dockerfile used as below with the same logic .

FROM tomcat:8.0
COPY sample.war /usr/local/tomcat/webapps/

Please let me know if I am doing anything wrong ..

Regards,

Satwik

When building with Packer no metadata is inherited like when you build with a Dockerfile. So you need to refine CMD, ENTRYPOINT etc.
