Boo

The purpose of Boo is to provide a simple command-line tool for the OneOps developers and OneOps users to deploy, update, destroy and operate their OneOps assemblies.

For the OneOps pack developers, it provides a fast and repeatable way to run tests against complex OneOps packs. For example, it allows a pack developer to use a short, one-line bash command to verify a parameter or code changes in an OneOps pack by attemping to instantiate the updated pack and executing tests on the resulting functional cluster. For an OneOps user, it provides an command-line tool to deploy, update, destroy and operator their OneOps assemblies. The boo tool is an addition to the OneOps UI interfaces.

Usage

To use Boo you download the executable JAR and place it in your $PATH. Use the latest version available from http://repo1.maven.org/maven2/com/oneops/boo/boo e.g.:

curl -o boo http://repo1.maven.org/maven2/com/oneops/boo/boo/1.0.18/boo-1.0.18-executable.jar

chmod +x boo

boo <options>

For debug use:

java -Dorg.slf4j.simpleLogger.defaultLogLevel=debug -jar boo <options>

To see what options are available for use:

boo -h

Configuration

Boo YAML templates are processed with Mustache to allow variable interpolation when the standard ~/.boo/config file contains a default profile. If you have a default profile that looks like the following:

[default]
host=https://localhost:9090
organization=devtools
api_key=oneops_api_key # copy from OneOps UI->profile->authentication->API Token
email=jvanzyl@walmart.com
cloud=prod-cdc6

With a Boo YAML template that looks like this:

boo:
  oneops_host: '{{host}}'
  organization: '{{organization}}'
  api_key: '{{api_key}}'
  email: '{{email}}'
  environment_name: 'dev'
  ip_output: 'json'
  clouds:
    {{cloud}}:
       priority: '1'
       dpmt_order: '1'
       pct_scale: '100'

...

It will yield the following:

boo:
  oneops_host: 'https://localhost:9090'
  organization: 'devtools'
  api_key: 'oneops_api_key'
  email: 'jvanzyl@walmart.com'
  environment_name: 'dev'
  ip_output: 'json'
  clouds:
    prod-cdc6:
       priority: '1'
       dpmt_order: '1'
       pct_scale: '100'

...

If you want to see what your Boo YAML template will look like with interpolated values you can use the following command:

boo -f boo.yml -v

Inlining File Content

You can use the file directive to inline content into a Boo template. The following are examples of how you can inline the content of files:

{{file(./id_rsa.pub)}}
{{file(~/.ssh/id_rsa.pub)}}
{{file(/Users/jvanzyl/id_rsa.pub)}}

So, for example, if you wanted to inline the content of your public SSH key into your Boo template before execution you can do the following:

user:
  user-jvanzyl:
    system_account: true
    sudoer: true
    username: 'jvanzyl'
    description: "JvZ"
    authorized_keys: '["{{file(~/.ssh/id_rsa.pub)}}"]'

The result will look something like:

user:
  user-jvanzyl:
    system_account: true
    sudoer: true
    username: 'jvanzyl'
    description: "JvZ"
    authorized_keys: '["ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7g6cjv8yxH0pbo..."]'

Again, you can see what the result will be using boo -f your.yml -v.

When using file(), multiple lines will be combined together when the YAML file is processed. In order to preserve multiple lines, use multilineFile().

For example, the following can be used to create an INI file template from an external file. If you have:

sample.ini

[general]
environment=dev
user=bob

then this configuration:

file:
  file-config:
    path: '/etc/sample.ini'
    content: '{{multilineFile(sample.ini)}}'

will expand to:

file:
  file-config:
    path: '/etc/sample.ini'
    content: '[general]

environment=dev

user=bob
'

The blank lines are inserted so that when the YAML is processed, the resulting string will contain the line breaks.

Development

Build the source code to an executable command:

mvn clean package

chmod +x ./target/boo-1.0.10-executable.jar

mv ./target/boo-1.0.10-executable.jar boo

boo <options>

Build to an RPM

mvn clean package -Pbuild-rpms

Find the rpm at .//target/rpm/boo/RPMS/noarch/boo-1.0.10*.noarch.rpm

Install the RPM

On Linux: sudo rpm -ivh boo-1.0.10*.noarch.rpm
On Mac: sudo rpm -ivh boo-1.0.10*.noarch.rpm --nodeps

Running integration tests

The integration tests take some time to run as they spin up real assemblies, validate them and spin them down. To run the integration tests along with the tests use the following:

mvn clean verify -Pits

Note that in order to run the integration tests you also need a default profile in your ~/.boo/config that looks like the following:

[default]
host=https://localhost:9090
organization=oneops_org_name
api_key=oneops_api_key
email=me@email.com
cloud=cloud_name_in_oneops

Deploying SNAPSHOT

mvn clean deploy -P release

Releasing

Provided you have permissions to deploy to OSSRH with a serverId ossrh in your settings and the needed gpg setup you can build and deploy a release with

mvn release:prepare
mvn release:perform

And then just check and release the staging repo on https://oss.sonatype.org

Code style

Boo uses the Google code style. The formatter for Eclipse you can find here:
