GO package that provides a Travis CI framework for testing Service Catalog Instances.

Download files

To setup a gate with Travis you need the file .travis.yml checked into your repo.

curl -o .travis.yml https://raw.githubusercontent.com/rthallisey/service-broker-ci/master/travis.yml

In order to allow Travis to install go in the gate, there needs to be a go file in your repo.

curl -O https://raw.githubusercontent.com/rthallisey/service-broker-ci/master/travis.go

Finally, curl an example config.yaml to help guide you.

curl -O https://raw.githubusercontent.com/rthallisey/service-broker-ci/master/config.yaml

Creating the ClusterServiceInstance template

At this point, you have already written your apb. Let's create the ServiceInstance template that will launch your apb.

When using the apb tool, run apb serviceinstace to generate a ServiceInstance template. You will need to edit parameters and select a plan before it's an acceptable resource.

Naming your resource

It's required that the resource being created shares the name with the ServiceInstance. The matching names are used to identify which resource will receive the bind data.

Config.yaml Syntax

The file config.yaml will hold the instructions for running the gate. Inside config.yaml there are five API KEYS allowed:

  • provision | Create an application
  • bind | Connect an application
  • unbind | Delete an application connection
  • deprovision | Delete an application
  • verify | Verify an action succeeded

They are expected to be in the format:

<API KEYS>: <FILE>

The FILE field accepts a valid git repo rthallisey/service-broker-ci/postgresql of any APB or a local file/script wait-for-resources.sh. The Four API Keys: provision , bind, unbind, and deprovision expect a template so the .yaml extention will be added automatically by the framework.

Verify

Verify is used to check if an action is successful. Use it to determine whether your APB lifecycle worked as expected. Verify accepts a script from git repo rthallisey/service-broker-ci/wait-for-resource.sh or a local script wait-for-resource.sh.

The Verify API Key is also a shell. It can run any shell command and return the output.

verify: oc get pods

The Verify action is optional, but it's highly recommended you use it to verify that your apb worked correctly. Example verification scripts:

Config file format

Templates used by provision, bind, unbind, and deprovision are expected to be in the templates directory. Everything else uses the full path provided.

.
|── templates
│   ├── mediawiki123.yaml
│   ├── postgresql-mediawiki123-bind.yaml
│   └── postgresql.yaml
Using Local Paths

The config file accepts local paths to scripts and templates.

Every template will be searched for in the templates directory locally while other scripts will use the top level directory.

provision: mediawiki123
verify: wait-for-resource.sh create pod mediawiki
Matching Paths

When describing a path to a template, that path will be the key used to identify which app is being acted upon.

For example, to provision and deprovision the same postgresql app, use matching paths.

provision: postgresql
verify: wait-for-resource.sh create pod postgresql

deprovision: postgresql
verify: wait-for-resource.sh delete pod postgresql

Bind Ordering

There are two applications that are used in a bind, the bindApp and the bindTarget. The bindApp is the application that will be binded to another application. If I say: "I want to bind postgresql to mediawiki". Then, the bindApp will be postgresql. The application that is being binded to, or is receiving the bind credentials, is the bindTarget. Mediaiwiki is the bindTarget from the example.

In config.yaml, the bindTarget is determined by the first application provisioned that's not the same as the bindApp.

This will bind postgresql to mediawiki123.

provision: rthallisey/service-broker-ci/mediawiki123
provision: rthallisey/service-broker-ci/postgresql

bind: rthallisey/service-broker-ci/postgresql

You can do multiple bindings with different applications where the next bind call will bind to the next availble provisioned application.

This will bind postgresql to mediawiki123 and mariadb to elasticsearch.

provision: rthallisey/service-broker-ci/mediawiki123
provision: rthallisey/service-broker-ci/elasticsearch

provision: rthallisey/service-broker-ci/postgresql
provision: rthallisey/service-broker-ci/mariadb

bind: rthallisey/service-broker-ci/postgresql
bind: rthallisey/service-broker-ci/mariadb
