awslogs-agent-setup.py not working on Ubuntu 17.10 (artful)

问题

This works fine on ubuntu 16.04, but not on 17.10

+ curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O

I noticed that earlier on in the process, in the AWS boilerplate it failed to install libyaml-dev but not sure if that's the only problem.

Always find the answer right after I post it...

Here's my modified CF template command:

    050_install_awslogs:
      command: !Sub 
        "/bin/bash -x\n
        exec >>/var/log/cf_050_install_awslogs.log 2>&1 \n
        echo 050_install_awslogs...\n
        set -xe\n
        # Get the CloudWatch Logs agent\n
        mkdir /opt/awslogs\n
        cd /opt/awslogs\n
        # Needed for python3 in 17.10\n
        apt-get install -y libyaml-dev python-dev \n
        pip3 install awscli-cwlogs\n
        # avoid it complaining about not having /var/awslogs/bin/aws binary\n
        if [ ! -d /var/awslogs/bin ] ; then\n
          mkdir -p /var/awslogs/bin\n
          ln -s /usr/local/bin/aws /var/awslogs/bin/aws\n
        fi\n
        curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O\n
        chmod +x ./awslogs-agent-setup.py\n
        # Hack for python 3.6 & old awslogs-agent-setup.py\n
        sed -i 's/3,6/3,7/' awslogs-agent-setup.py\n
        ./awslogs-agent-setup.py -n -c /etc/awslogs/awslogs.conf -r ${AWS::Region}\n
        echo 050_install_awslogs end\n
        "

Not entirely sure about the need for the dir creation but I expect this is a temporary case that will get resolved soon as one still needs to fudge the python 3.6 compatibility check.

it may be installable using python 2.7 as well, but that felt like going backwards at this point as the my rationale for 17.10 was python 3.6.

Credit for the yaml package and dir creation idea to https://forums.aws.amazon.com/thread.jspa?threadID=265977 but I prefer to avoid easy_install.

I had similar issue on Ubuntu 18.04.

Instruction from AWS for standalone install worked for my case.

To download and run it standalone, use the following commands and follow the prompts:

curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O
curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/AgentDependencies.tar.gz -O
tar xvf AgentDependencies.tar.gz -C /tmp/
sudo python ./awslogs-agent-setup.py --region us-east-1 --dependency-path /tmp/AgentDependencies
