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)
- Obligatory disclaimer about logs & disk space... upstart will rotate/etc; but growth of backend, will just keep going. Don't let your docker host run out of space!
- 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
