Key Forwarding to the VM

It is important to set up ssh key forwarding to enable your use of git repositories while logged into the VM. Key forwarding should be enabled for the VM's two fake host identities:

cakelampvm.com
10.28.42.20

The details of configuring ssh key forwarding vary for each ssh + client. For Linux ssh, the ~/.ssh/config file might contain + this information:

Handy Techniques for Using cakelampvm
+
Assorted Guides and Cheat-Sheets
+
A Cheat sheet for the Vim editor (there are many of these available): https://vim.rtorr.com/
+
A git branching model that seems to work well: http://nvie.com/posts/a-successful-git-branching-model/
+
This is a basic guide to the Google Developer Console and API Key + management: Google + API Docs
+
Using the "meld" Tool to Compare Files & Directories
+
Meld is a great comparison tool that displays differences between two + files or directories or directory trees in a graphical view. Meld is + pre-installed on the VM. This tool can be launched either in the + VM's X Windowing System (on the console) or if X11 forwarding is enabled.
+
To run meld, just type this command:
+
```
meld A B
```
+
where A and B are either both file names or they are both directory + names. If A and B are directories, meld will compare the entire tree + structure between the two directories. It allows one to copy from + one side to the other, even if the item that needs to be copied is an + entire subdirectory.
+
Get the network address on the guest vm
+
Run this command:
+
```
ifconfig
```
+
In the results, look for "inet addr". + There may be more than one, if there are multiple network interfaces.
+
The standard IP address is 10.28.42.20 for the cakelampvm.
+
How to cleanly reboot or shut down the guest VM
+
When you've got the DNS and everything integrated, these commands will + manage the vm's state:
+
First, log into the guest VM:
+
```
ssh developer@cakelampvm.com
```
+
Then, to reboot the guest VM:
+
```
sudo reboot
```
+
Or, to halt the guest VM:
+
```
sudo shutdown -h now
```
+
Using these commands is kinder to the VM than just cycling the power from + the Virtualbox control panel.
+
Gritty Details of the Nitty Variety
+
This is the lowest level of plumbing for your VM. Hopefully you + will not need to engage with this section. The most useful doc + section here is the one below about the "Virtualbox guest additions", + which you will probably need at some future point. Oracle releases + updates to the guest additions fairly regularly.
+
Configuring the guest VM
+
The guest VM should already be set up appropriately. These steps + are provided for reference and updates.
+
Set up Virtualbox guest additions for the VM
+ This procedure is needed if the guest provides an older or incompatible + version of the guest additions (which have already been installed on the + guest vm). It may also be necessary when a new version of the guest + additions becomes available. +
1. To install the guest additions, open the guest VM and have its window + in focus.
2. Choose the "Devices" menu and select "Insert Guest Additions CD + Image". This will mount the CD's ISO image on the VM.
3. On the guest VM, it may be necessary to mount the CD image that's now + available:
  +
```
sudo mount /dev/sr0 /media/cdrom
```
  +
  Linux will mention that the device is mounted "read-only".
  +
4. Since the VM currently has no windowing system installed, one must + start the Guest Additions install manually:
  +
```
cd /media/cdrom
sudo sh VBoxLinuxAdditions.run
```
  +
5. The latest Virtualbox guest additions should now be installed.
+
Set up network adapters on guest VM
+
The network interfaces should already be configured on the guest within + the Virtualbox configuration. This is available by clicking on the + VM in the Virtualbox manager and selecting "Settings". These are the + configuration settings used:
+ Adapter 1:
+ Attached to: Host-only Adapter
+ Name: vboxnet0
+
Adapter 2:
+ Attached to: Nat Network
+ Name: NatNetwork
+
On the guest VM itself, the network settings are specified in a file + called /etc/network/interfaces. Here are the current contents of + that file:
+
```
source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

auto enp0s3
iface enp0s3 inet static
  address 10.28.42.20
  netmask 255.255.255.0
  network 10.28.42.0
  broadcast 10.28.42.255
  dns-domain cakelampvm.com
  dns-search cakelampvm.com
  dns-nameservers 127.0.0.1 8.8.8.8
```
+
```
auto enp0s8
```
+
```
iface enp0s8 inet dhcp
```
+

+
Compacting the VM Disk Image
+
To minimize the size used for the disk image, there are three major + steps.
+
1. While running the VM, run this command:
+
```
sudo apt clean
```
+
This throws away any cached data from the apt tool, which can be + substantial.
+
If there are other junk files you know of that can be removed, delete + those now also.
+
2. Reboot the VM to the gparted ISO image (available at the gparted + site) and run the following command:
+
```
sudo zerofree /dev/sda
```
+
This sets all free space to the zero byte, enabling Virtualbox to free + that space in the next step.
+
3. Shut the vm down after zerofree is complete and run this command on + the host PC (this is the Linux version of the command):
+
```
VBoxManage modifyhd --compact ~/cake_lamp_vm/cake-lamp-vm-hd.vdi
```
+
Replace the ~/cake_lamp_vm + path with the real VM storage path. This command compacts the root + (and only) partition of the VM.
+
After these steps are complete, the VM should be its minimal size.
