To start server locally:

gem install nats
nats-server

To subscribe:

nats-sub '>' -s nats://localhost:4222

To publish:

nats-pub agent.123-456-789 '{"method":"apply","arguments":[{"packages":[{"name":"package-name", "version":"package-version"}]}]}' -s nats://localhost:4222

The Go Agent ships with 4 default blobstores:

• Local filesystem
• S3
• DAV
• Dummy (for testing)

You can, however, use custom blobstores by implementing a simple interface. For example, if you want to use a blobstore named "custom" you need to create an executable named bosh-blobstore-custom somewhere in PATH. This executable must conform to the following command line interface:

• -c flag that specifies a config file path (this will be passed to every call to the executable)
• must parse the config file in JSON format
• must respond to get <blobID> <filename> by placing the file identified by the blobID into the filename specified
• must respond to put <filename> <blobID> by storing the file at filename into the blobstore at the specified blobID

A full call might look like:

bosh-blobstore-custom -c /var/vcap/bosh/etc/blobstore-custom.json get 2340958ddfg /tmp/my-cool-file

Note: This guide assumes a few things:

• You have gcc (or an equivalent)
• You can install packages (brew, apt-get, or equivalent)

Get Golang and its dependencies (Mac example, replace with your package manager of choice):

• brew update
• brew install go
• brew install git (Go needs git for the go get command)
• brew install hg (Go needs mercurial for the go get command)

Clone and set up the BOSH Agent repository:

• go get -d github.com/cloudfoundry/bosh-agent
  • Note that this will print an error message because it expects a single package; our repository consists of several packages. The error message is harmless—the repository will still be checked out.
• cd $GOPATH/src/github.com/cloudfoundry/bosh-agent

From here on out we assume you're working in $GOPATH/src/github.com/cloudfoundry/bosh-agent

Install tools used by the BOSH Agent test suite:

• bin/go get code.google.com/p/go.tools/cmd/vet
• bin/go get github.com/golang/lint/golint

Each package in the agent has its own unit tests. You can run all unit tests with bin/test-unit.

Additionally, BOSH includes integration tests that use this agent. Run bin/test-bosh-integration to run those with your local agent changes. However, in order to run the BOSH integrations tests, you will need a copy of the BOSH repo, which this script will do in ./tmp. BOSH uses Ruby for its tests, so you will also need to have that available.

You can run all the tests by running bin/test.

There is a stand-alone BOSH Agent integration test to test config-drive using bosh-lite. This can be run locally via integration/bin/test --provider=virtualbox. The vagrant provider passed in can be changed to a provider of your choosing if you so desire.

• Install IntelliJ 13 (we are using 13.0.1 Build 133.331)
• Install the latest Google Go plugin for IntelliJ. You may want to grab the latest early access (EAP) build, rather than the last release.
• (Optional) Download, Install & Select improved keybindings for IntelliJ:
  • git clone [email protected]:Pivotal-Boulder/IDE-Preferences.git
  • cd ~/Library/Preferences/IntelliJIdea13/keymaps
  • ln -sf ~/workspace/IDE-Preferences/IntelliJKeymap.xml
  • In IntelliJ: Preferences -> Keymap -> Pick 'Mac OS X 10.5+ Improved'
• Clone bosh-agent into a clean go workspace (or use a bosh clone with bosh/go as the workspace root):
  • mkdir -p ~/workspace/bosh-agent-workspace/src/github.com/cloudfoundry
  • cd ~/workspace/bosh-agent-workspace/src/github.com/cloudfoundry
  • git clone https://github.com/cloudfoundry/bosh-agent
• Open ~/workspace/bosh-agent-workspace as a new project in IntelliJ.
• Set the Go SDK as the Project SDK:
  • Open the Project Structure window: File -> Project Structure
  • Select the Project tab in left sidebar
  • (Optional) Add a New Go SDK by selecting your go root.
  • Select Go SDK go1.3 under Project SDK
• Setup module sources
  • Open the Project Structure window: File -> Project Structure
  • Select the Modules tab in left sidebar
  • Select your module in the middle sidebar
  • Select the Sources tab in the Module pane
  • Select ~/workspace/bosh-agent-workspace/src and add is as a source dir
  • Select ~/workspace/bosh-agent-workspace/src/github.com/cloudfoundry/bosh-agent/Godeps and add is as an excluded dir
• Setup module dependencies
  • Open the Project Structure window: File -> Project Structure
  • Select the Modules tab in left sidebar
  • Select your module in the middle sidebar
  • Select the Dependencies tab in the Module pane
  • Select the + -> Jars or directories... to add ~/workspace/bosh-agent-workspace/src/github.com/cloudfoundry/bosh-agent/Godeps/_workspace as a sources dependency
  • Rename the new dependency to Godeps
  • Use the arrow buttons to move Godeps above Go SDK and below <Module source>
• Set the bosh-agent dir as the Git root to enable version control
  • Select the - to remove the project root
  • Select the + to add the ~/workspace/bosh-agent-workspace/src/github.com/cloudfoundry/bosh-agent dir
• Install & configure the Grep Console plugin
  • Install via Preferences -> Plugins
  • Select Preferences -> Grep COnsole -> Enable ANSI coloring to colorize Ginkgo test output
• Re-index your project: File -> Invalidate Cache / Restart

You should now be able to 'go to declaration', auto-complete, and run tests from within IntelliJ.
