Cloning and Building

---

Clone this repo and build it. Using the following commands on a Linux or Mac OS X system:

$ mkdir -p bosh-lattice-cpi/src/github.com/cloudcredo
$ export GOPATH=$(pwd)/bosh-lattice-cpi:$GOPATH
$ cd bosh-lattice-cpi/src/github.com/cloudcredo
$ git clone https://github.com/cloudcredo/bosh-lattice-cpi.git
$ cd bosh-lattice-cpi
$ ./bin/build
$ ./bin/test-unit
$ export [email protected]
$ export SL_API_KEY=your-softlayer-api-key
$ ./bin/test-integration

NOTE: if you get any dependency errors, then use go get path/to/dependency to get it, e.g., go get github.com/onsi/ginkgo and go get github.com/onsi/gomega

The executable output should now be located in: out/cpi. You will need to package this into a BOSH release. The easiest way is to use the bosh-lattice-cpi-release project.

Running Tests

---

The SoftLayer (SL) CPI and associated tests and binary distribution depend on you having a real SL account. Get one for free for one month here. From your SL account you can get an API key. Using your account name and API key you will need to set two environment variables: SL_USERNAME and SL_API_KEY. You can do so as follows:

$ export [email protected]
$ export SL_API_KEY=your-softlayer-api-key

You should run the tests to make sure all is well, do this with: $ ./bin/test-unit and $ ./bin/test-integration in your cloned repository. Please note that the $ ./bin/test-integration will spin up real SoftLayer virtual guests (VMs) and associated resources and will also delete them. This integration test may take up to 30 minutes (usually shorter)

The output should of $ ./bin/test-unit be similar to:

$ ./bin/build
$ ./bin/test-unit

Developing

---

1. Run go get golang.org/x/tools/cmd/vet
2. Run go get github.com/xxx ... to install test dependencies (as you see errors)
3. Write a Ginkgo test.
4. Run bin/test and watch the test fail.
5. Make the test pass.
6. Submit a pull request.

Contributing

---

• We welcome any and all contributions as Pull Requests (PR)
• We also welcome issues and bug report and new feature request. We will address as time permits
• Follow the steps above in Developing to get your system setup correctly
• Please make sure your PR is passing Travis before submitting
• Feel free to email me or the current collaborators if you have additional questions about contributions

Managing dependencies

---

• All dependencies managed via Godep. See Godeps/_workspace directory on master

Short godep Guide

• If you ever import a new package foo/bar (after you go get foo/bar, so that foo/bar is in $GOPATH), you can type godep save ./... to add it to the Godeps directory.
• To restore dependencies from the Godeps directory, simply use godep restore. restore is the opposite of save.
• If you ever remove a dependency or a link becomes deprecated, the easiest way is probably to remove your entire Godeps directory and run godep save ./... again, after making sure all your dependencies are in your $GOPATH. Don't manually edit Godeps.json!
• To update an existing dependency, you can use godep update foo/bar or godep update foo/... (where ... is a wildcard)
• The godep project readme is a pretty good resource: https://github.com/tools/godep

Current conventions

---

• Basic Go conventions
• Strict TDD for any code added or changed
• Go fakes when needing to mock objects

The base code was inpired by cppforlife's BOSH Warden CPI's example external Go-language CPI.

NOTE: This is still work in progress. No guarantees are implied that this will be usable nor finish. Consider this code as prototype code.
