Working with Ansible on Mac OS X

[emAmazed]

Initial Installation

Note: For Ansible installation on Mac, I will highly recommend using package installation. This will avoid additional step to manually create configure file such as install from the source or using brew install.

• Only your control node needs to have ansible to be installed on
• sudo easy_install pip
• sudo pip install ansible

You should have something look like this:

• Reference: http://docs.ansible.com/ansible/intro_installation.html#latest-releases-via-pip

Troubleshooting on Configuration

• easy_install is extremely convenient. But it is also lacking of dependency manager. The most common error you will see is "DistributionNotFound" for certain package(s). To fix it -

• install package individually

  sudo pip install <packagename>

• uninstall pip and reinstall

  sudo pip uninstall pip sudo easy_install pip

• a fresh reinstall

  $ wget https://bootstrap.pypa.io/get-pip.py $ sudo python get-pip.py sudo pip uninstall <packagename> sudo pip install <packagename> (most effective)

Create ansible hosts inventory file

• Create a hosts file under /etc/ansible/hosts
• Update the ansible configuration file variables. e.g. remote_user, private_key_file, etc.
• Examples: [webservers] 111.112.113.114 111.112.114.115 [dbservers] 10.11.12.13 10.11.14.15

Ad-Hoc ansible command

• Examples:

  ansible webservers -m ping

ansible webservers -s -C -m yum -a "name=httpd state=latest"

Playbook

Install boto to connect S3 bucket

sudo pip install boto

Install awscli Tool on OSX

This will install the most recent version of awscli

curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"

unzip awscli-bundle.zip

install awscli tool to your preferred location

./awscli-bundle/install -b my/preferred/path/aws

get PATH from workspace

export $PATH | grep my/preferred/path

add awscli path to your env PATH

export PATH=my/preferred/path:$PATH

OR

create symbolic link from your PATH

ln -s my/preferred/path/aws /user/local/bin/aws

Upload files to S3 bucket using ansible

Sync S3 repo to EC2 node

• on EC2 node, config s3 variables

sudo su -

aws configure

Access ID Key ......

Secret Key ....

region [get node region]

output format [e.g. json]

aws s3 sync s3://[bucket-name]/[repo-name] [web-root]/[project-name]

Update Security Key Pairs Using Boto

• on EC node, or workspace, modify /etc/boto.cfg
