# 'values' is a built-in method and therefore always exists. This is especially useful for "influxDB" API output from an uri command. 
# test attribute type with selectattr('fieldname', TEST), see http://jinja.pocoo.org/docs/dev/templates/#list-of-builtin-tests
ansible localhost -m command -a "echo {{ [ { 'values': 'foo' }, { 'name': 'bar' } ] |selectattr('values', 'string') |map(attribute='values') |list  }}"
# alternatively filter:
ansible localhost -m command -a "echo {{ [ { 'values': 'foo' }, { 'name': 'bar' } ] |rejectattr('values', 'callable') |map(attribute='values') |list  }}"

INFO

• remote SSH shell on macOS does not use /etc/paths
• this is not an issue of ansible, it is the way macOS processes config files on remote shells:
• see ssh localhost echo \$PATH

ANSIBLE executes remote shell /bin/sh

• ...if not specified otherwise and macOS does not read any startup files
• example: [...]localhost '/bin/sh -c '"'"'sudo -H -S -n -u test /bin/sh -c '"'"'"'"'"[...]
• even /bin/bash does not read any startup files by default

Run travis build locally

• based on and trying to reproduce: https://stackoverflow.com/questions/21053657/how-to-run-travis-ci-locally/49019950#49019950

• get the right build image from your travis build online (check build logs for "INSTANCE")

• search for a matching docker image on docker hub

• TODO: make a docker file out of this

• from https://hub.docker.com/r/travisci/ubuntu-ruby/tags

cd <to you project directory>

create or update a version branch from master

• only do this if your branch is just based on a different version than master
• it is discouraged to do this for branches that have significant differences to master!
• see it in action: https://github.com/DrPsychick/docker-telegraf

# make sure to have your origin set correctly
# git remote set-url origin "[email protected]:DrPsychick/docker-telegraf.git"

branch="testbranch"
# checkout master from origin, skip if you already have a fresh checkout!
