Problem with AWS Elastic Beanstalk Docker Multi-Container (PHP, Nginx)

I have a problem with docker multicontainer in Elastic Beanstalk AWS, it turns out that I'm starting with this whole docker theme and between information and documentation I managed to create my file "dockerrun.aws.json", which clearly is not well configured, because when executing an "eb deploy" it falls indicating the following error

By entering the log of the ec2 corresponding to elastic beanstalk tells me the following

*[2018-10-16T21:45:29.709Z] INFO  [25309] - [Application update app-2a8e3-181016_183848@50/AppDeployStage1/AppDeployEnactHook/03start-task.sh] : Activity execution failed, because: + . /opt/elasticbeanstalk/hooks/common.sh

So that you can help me, I leave you my dockerrun.aws.json

                }
            ]
        }
    ]
}*

I tried to execute it without the command thinking that it could be the error, but it throws me the same, so I think it may be something else, but I can not identify the problem.
