packer-local-test

Goal

Toy project that will try to create a test suite for packer.

Main Idea

If local host have bzr, go and gox we will build locally. If local host have virtualbox, vmware, docker we will try to test locally.

Then, we will be using vmware-vmx will spin a vm and test packer with a suite of known test.

Workflow

If GOPATH is set, will:

• go get if there is no $GOPATH/src/github.com/mitchellh/packer
• git fetch if there is $GOPATH/src/github.com/mitchellh/packer
• ensure pr/* is part of the repo
• run make updatedeps on first run, or if updatedeps is an argument

If GOPATH is set, and bzr, go, gox are available, it will:

• make test
• make dev

TODO

• be able to:

[ <master> || <branch> || <number> || <latest> ]

• have some known template.json and run packer validate
• based on what's available, do some packer build
• if vmware is available, do some nested vm for a more complete suite of tests

Local requirements

• git
• bzr
• go
• gox
• GOPATH

Helper file

A file will be provided, packer-local-test.sh that will do some heavy lifting.

packer-local-test.sh  master // will checkout to master
packer-local-test.sh  nnnn // will checkout to pr/nnnn

If go and gox are available, the helper will try to compile locally.

Usage ie:

$ bash packer-local-test.sh 2810
/Volumes/hd1/Dropbox/am/Git/kikitux/packer-local-test/packer /Volumes/hd1/Dropbox/am/Git/kikitux/packer-local-test

Tips that will make thing easier

git clone https://github.com/mitchellh/packer.git
cd packer
git config --add remote.origin.fetch '+refs/pull/*/head:refs/remotes/origin/pr/*'
git fetch

Then

git checkout pr/2805

ie:

$ git checkout master

$ git checkout pr/2805
