Notes on creating the Virtual Box environment for Guardian integration testing

  • Get Virtual Box 4.3.10 from Oracle

  • Install and open vBox manager

  • Create a vm (named Guardian Dev Test)

    • 2Gb RAM
    • 8Gb HDD
    • 4 processors
    • username (spowell)
    • password (********)
    • o/w defaults (ensure network connection -- NAT default)

  • Get Ubuntu (or other distro)

    • ubuntu-14.04-desktop-amd64.iso (got from Glyn)

  • Start vm and install from DVD

    • accept updates during boot/install
    • reboot (no need to remove DVD)

  • Install VBox Guest Additions

    • Devices menu in VBox (after booting VM) attaches image
    • Accept in dialog
    • Reboot (and get largest resolution for display -- can maximise afterwards, so don't worry)

  • Get git and mercurial (needed by go get)

    • sudo apt-get install git mercurial

  • Get go

    • (Firefox download from golang -- Ubuntu 64bit version -- version 1.2.2 current)

    • After installation rename to ~/golang

    • Edit .profile to include:

        export GOROOT=$HOME/golang
  export GOPATH=$HOME/go
  export PATH=$GOPATH/bin:$PATH:$GOROOT/bin

    • Check we have the right version:

      • Reboot (.profile not rexecuted on restart Terminal? Then modify run terminal as login shell in Terminal preferences.)
      • go version in Terminal/Shell to check
      • env|grep GO to check setup

  • Now get the Guardian code

      go get github.com/cf-guardian/guardian

  • Now build/test something

      cd ~/go/src/github.com/cf-guardian/guardian/kernel/rootfs
  go get -t ./...
  go test

    We should get gomock and glog as a byproduct of this.

Alternative to getting the Guardian code

Share a folder with the host copy of the Guardian code.

  • Create shared folder on vbox
    • point to go project source root (GOPATH) on host
    • choose name for it (e.g. gohost)
    • is mounted in /media/sf-gohost
    • put local user in vboxsf group or else the folder cannot be accessed (!)
  • The go compiler needs to be installed on the vbox, still, and then updates to the code on the host are immediately visible to the vbox machine.

INTELLIJ Go support on Mac OS X

Install Community Edition of INTELLIJ, and install the Golang.org plugin.

Then set up GOROOT and GOPATH in the /etc/launchd.conf file (which may need to be created by root) so as to get INTELLIJ to see these vars when started. These should be set to the same as they are in the host system. The Mac can be rebooted or issue

egrep -v '^\s*#' /etc/launchd.conf | launchctl

to make the new settings "take" straight away. Then restart INTELLIJ.

Create a new Go project for INTELLIJ, do not create a new src folder, but point to the src folder for guardian:

~/dev/go/github.com/cf-guardian/guardian

(for me).

There is more to do: the source files for the Go project need to be set:

  • go to the module/project settings, and navigate to the SDK settings
  • clear the stuff in the ClassPath section -- this is not needed
  • make sure the $GOROOT/src/pkg (in full, not using the env var, I don't think) is present
