README.md

dockerana

Overview:

  • time series docker instrumentation and visualization
  • built/tested as drop-in on Ubuntu Trusty at the moment, need to test on boot2docker
  • need to test across multiple hosts (whisper/elasticsearch/etc)

Initial setup :

  • Obligatory disclaimer about logs & disk space... upstart will rotate/etc; but growth of backend, will just keep going, if you fill your docker host things will be bad
  • Everything in this setup assumes ipv4 only at this point (FIXME)

Instructions below are for Ubuntu 14.04, assuming a vanilla/patched install with rsyslog running.

Official install from http://docs.docker.io/installation/ubuntulinux/#ubuntu-trusty-1404-lts-64-bit

sudo apt-get update
sudo apt-get install -y docker.io
sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker
sudo sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io

Update to a current docker:

cd /tmp
wget https://get.docker.io/builds/Linux/x86_64/docker-latest -O docker
sudo mv docker /usr/bin/docker.io
sudo chown root:root /usr/bin/docker.io
sudo chmod 755 /usr/bin/docker.io

Make these changes :

(FIXME deal with situation where pre-existing docker_opts exist/ordering/etc)

printf "\n# Added for dockerana log aggregation\nDOCKER_OPTS=\" -D\"\n" | sudo tee -a /etc/default/docker.io > /dev/null
sudo perl -pi -e 's/(\"\$DOCKER\" -d \$DOCKER_OPTS)/$1 2>&1 | logger -t docker\n\tnetstat --interfaces -c | logger -t netstat &/' /etc/init/docker.io.conf

Go ahead and re-start docker:

sudo service docker.io restart

To build dockerana:

git clone https://github.com/dockerana/dockerana.git
cd dockerana
./build

To start:

./start

To stop:

./stop
