This document has moved!

It's now here, in The Programmer's Compendium. The content is the same as before, but being part of the compendium means that it's actively maintained.

Ansible 1.3 Conditional Execution -- Very complete example with comments -- I find the conditional expressions to be ridiculously hard to get right in Ansible. I don't have a good model of what's going on under the surface so I often get it wrong. What makes it even harder is that there has been at least three different variants over the course …

# This has been tested with ansible 1.3 with these commands:
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=false"
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=true"
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts"
# NB: The type of the variable is crucial!

Elasticsearch Tuning Plan

Next Steps

  • Measure time spend on index, flush, refresh, merge, query, etc. (TD - done)
  • Take hot threads snapshots under read+write, read-only, write-only (TD - done)
  • Adjust refresh time to 10s (from 1s) and see how load changes (TD)
  • Measure time of a rolling restart doing disable_flush and disable_recovery (TD)
  • Specify routing on query -- make it choose same node for each shard each time (MD)
  • GC new generation size (TD)
  • Warmers
  • measure before/after of client query time with and without warmers (MD)

Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo.
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh
