Duffle is a command line tool that allows you to install and manage CNAB bundles. To learn more about about CNAB and duffle, check out the docs.

Getting Started

1. Ensure you're running the latest version of Go (1.11+) by running $ go version

   $ go version
   go version go1.11 darwin/amd64

2. Clone this repo:

   $ cd $GOPATH/src/github.com/deislabs/
   $ git clone [email protected]:deislabs/duffle.git
   $ cd duffle

3. Vendor dependencies and build the duffle binary:

   $ make bootstrap build

4. Run the command to set duffle up on your machine:

   $ duffle init
   The following new directories will be created:
   /Users/janedoe/.duffle
   /Users/janedoe/.duffle/logs
   /Users/janedoe/.duffle/plugins
   /Users/janedoe/.duffle/repositories
   /Users/janedoe/.duffle/claims
   /Users/janedoe/.duffle/credentials

5. Build and install your first bundle:

   $ duffle build ./examples/helloworld/
   Step 1/5 : FROM alpine:latest

   ==> Successfully built bundle helloworld:0.1.0
   

6. Check that it was built:

   $ duffle bundle list
   NAME            VERSION DIGEST                                          SIGNED?
   helloworld      0.1.0   b2747e5c36369f4c102f4f879caa94e607e5db7e        true

7. Now run it:

   $ duffle credentials generate helloworld-creds helloworld:0.1.0
   $ duffle install helloworld-demo -c helloworld-creds helloworld:0.1.0
   Executing install action...
   hello world
   Install action
   Action install complete for helloworld-demo

8. Clean up:

   $ duffle uninstall helloworld-demo
   Executing uninstall action...
   hello world
   uninstall action
   Action uninstall complete for helloworld-demo
