Whisk Deploy `wskdeploy`

wskdeploy is a utility to help you describe and deploy any part of the OpenWhisk programming model using a Manifest file written in YAML. Use it to deploy all your OpenWhisk Packages, Actions, Triggers, and Rules using a single command!

You can use this in addition to the OpenWhisk CLI. In fact, this utility uses the OpenWhisk "Go" Client to create its HTTP REST calls for deploying and undeploying your packages.

Building the project

GoLang setup

The wskdeploy utility is a GoLang program so you will first need to Download and install GoLang onto your local machine.

Make sure your $GOPATH is defined correctly in your environment. For detailed setup of your GoLang development environment, please read How to Write Go Code.

Get the source code from GitHub

Once your environment is setup, download wskdeploy and its dependencies:

$ cd $GOPATH
$ go get github.com/apache/incubator-openwhisk-wskdeploy  # see known issues below if you get an error

Build the binary

Use the Go utility to build the wskdeploy binary as follows:

$ cd src/github.com/apache/incubator-openwhisk-wskdeploy/
$ go build -o wskdeploy

building for other Operating Systems (GOOS) and Architectures (GOARCH)

If you would like to build the binary for a specific operating system, you may add the arguments GOOS and GOARCH into the Go build command. You may set

GOOS to "linux", "darwin" or "windows"
GOARCH to "amd64" or "386"

For example, run the following command to build the binary for 64-bit Linux:

$ GOOS=linux GOARCH=amd64 go build -o wskdeploy

build using GoDep tool

If you want to build with the godep tool, please execute the following commands.

$ go get github.com/tools/godep # Install the godep tool.
$ godep get                     # Download and install packages with specified dependencies.
$ godep go build -o wskdeploy   # build the wskdeploy tool.

Running `wskdeploy`

After building the wskdeploy binary, you can run it as follows:

Running the Binary file

Start by verifying the utility can display the command line help:

$ ./wskdeploy --help

then try deploying an OpenWhisk Manifest and Deployment file:

$ ./wskdeploy -m tests/usecases/triggerrule/manifest.yml -d tests/usecases/triggerrule/deployment.yml

Running as a Go program

Since wskdeploy is a GoLang program, you may choose to run it using the Go utility:

$ go run main.go --help

and deploying using the Go utility would look like:

$ go run main.go -m tests/usecases/triggerrule/manifest.yml -d tests/usecases/triggerrule/deployment.yml

Downloading released binaries

Binaries of wskdeploy are available for download on the project's GitHub release page:

https://github.com/apache/incubator-openwhisk-wskdeploy/releases.

For each release, we typically provide binaries built for Linux, Mac OS (Darwin) and Windows on the AMD64 architecture. However, we provide instructions on how to build your own binaries as well from source code with the Go tool. See Building the project.

If you are a Developer or Contributor, we recommend building from the latest source code from the project's master branch.

Contributing to the project

Start by creating a fork of incubator-openwhisk-wskdeploy and then change the git origin to point to your forked repository, as follows:

$ cd $GOPATH/src/github.com/apache/incubator-openwhisk-wskdeploy
$ git remote rename origin upstream
$ git remote add origin https://github.com/<your fork>/incubator-openwhisk-wskdeploy
$ git fetch --all
$ git branch --set-upstream-to origin/master  # track master from origin now

You can now use git push to push changes to your repository and submit pull requests.

Developers should use "go deps" and "go build" not "go get"

The Whisk deploy project is setup for development purposes and uses "go deps" for dependency management. We do NOT recommend using "go get" as this will use the latest dependencies for all imported GitHub repos. which is not supported.

See: https://github.com/tools/godep

Specifically, for development please use:

$ git clone git@github.com:mrutkows/incubator-openwhisk-wskdeploy
$ go build

for end-users, please use versioned releases of binaries.

How to Cross Compile Binary with Gradle/Docker

If you don't want to bother with go installation, build, git clone etc, and you can do it with Gradle/Docker.

After compiling, a suitable wskdeploy binary that works for your OS platform will be available under /bin directory.

First you need a docker daemon running locally on your machine.
Make sure you have Java 1.7 or above installed.
Clone the wskdeploy repo with command git clone https://github.com/apache/incubator-openwhisk-wskdeploy.git
If you use Windows OS, type gradlew.bat -version . For Unix/Linux/Mac, please type ./gradlew -version.
Make sure you can see the correct Gradle version info on your console. Currently the expected Gradle version is 3.3.
For Windows type gradlew.bat distDocker. For Linux/Unix/Mac, please type ./gradlew distDocker. These commands will start the wskdeploy cross compile for your specific OS platform inside a Docker container.
After build success, you should find a correct binary under current /bin dir of you openwhisk-deploy clone dir.

If you would like to build the binaries available for all the operating systems and architectures, run the following command:

$ ./gradlew distDocker -PcrossCompileWSKDEPLOY=true

Then, you will find the binaries and their compressed packages generated under the folder bin/<os>/<arch>/ for each supported Operating System and CPU Architecture pair.

Troubleshooting

Known issues

Git commands using HTTPS, not SSH

The "go get" command uses HTTPS with GitHub and when you attempt to "commit" code you might be prompted with your GitHub credentials. If you wish to use your SSH credentials, you may need to issue the following command to set the appropriate URL for your "origin" fork:

git remote set-url origin git@github.com:<username>/incubator-openwhisk-wskdeploy.git

you can manually change the remote (origin) url within your .git/config file:

[remote "origin"]
    url = git@github.com:<username>/incubator-openwhisk-wskdeploy

while there, you can verify that your upstream repository is set correctly:

[remote "upstream"]
    url = git@github.com:apache/incubator-openwhisk-wskdeploy

Git clone RPC failed: HTTP 301

This sometimes occurs using "go get" the wskdeploy code (which indirectly invokes "git clone").

Note: Using "go get" for development is unsupported; instead, please use "go deps" for dependency management.

You might get this error when downloading incubator-openwhisk-wskdeploy:

 Cloning into ''$GOAPTH/src/gopkg.in/yaml.v2'...
 error: RPC failed; HTTP 301 curl 22 The requested URL returned error: 301
 fatal: The remote end hung up unexpectedly

This is caused by newer git versions not forwarding requests anymore. One solution is to allow forwarding for gopkg.in

$ git config --global http.https://gopkg.in.followRedirects true
