You are just missing the cron package in your dockerfile. It doesn't matter if you have installed cron on your system. 

FROM ubuntu:latest

ENV AWS_REGION ap-northeast-1

RUN apt-get update && apt-get install -y curl python cron python-pip \
        && rm -rf /var/lib/apt/lists/*
COPY awslogs.conf ./

RUN curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O
RUN chmod +x ./awslogs-agent-setup.py
RUN ./awslogs-agent-setup.py --non-interactive --region ${AWS_REGION} --configfile ./awslogs.conf


RUN apt-get purge curl -y

RUN mkdir /var/log/awslogs
WORKDIR /var/log/awslogs

CMD /bin/sh /var/awslogs/bin/awslogs-agent-launcher.sh

After adding cron package to dockerfile everything works fine

Step 1 of 5: Installing pip ...DONE

Step 2 of 5: Downloading the latest CloudWatch Logs agent bits ... DONE


Step 5 of 5: Setting up agent as a daemon ...DONE


------------------------------------------------------
- Configuration file successfully saved at: /var/awslogs/etc/awslogs.conf
- You can begin accessing new log events after a few moments at https://console.aws.amazon.com/cloudwatch/home?region=us-west-2#logs:
- You can use 'sudo service awslogs start|stop|status|restart' to control the daemon.
- To see diagnostic information for the CloudWatch Logs Agent, see /var/log/awslogs.log
- You can rerun interactive setup using 'sudo python ./awslogs-agent-setup.py --region us-west-2 --only-generate-config'

Have you checked that a cron daemon is actually installed on your system ?

On other hand you can you can try manually installing pip3.5 install awscli-cwlogs or apt-get update && apt-get install -y python-pip libpython-dev

You can refer to this question
