Download Releases from Github using Curl and Wget

The issue

I was trying to download a software release from GitHub using Curl and hitting an issue, the file wasn’t large enough for a start, it was unusable and clearly not the file I expected.

curl -O https://github.com/kastenhq/external-tools/releases/download/3.0.12/k10tools_3.0.12_linux_amd64


% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 635 100 635 0 0 2387 0 --:--:-- --:--:-- --:--:-- 2387

I tested this in a browser and found the link redirects elsewhere, hence the issue.

The Fix

Just needed to specify a few extra arguments.

curl -LJO https://github.com/kastenhq/external-tools/releases/download/3.0.12/k10tools_3.0.12_linux_amd64

# Explanation of the arguments

-L, --location      Follow redirects
-J, --remote-header-name Use the header-provided filename
-O, --remote-name   Write output to a file named as the remote file

If you wish to use wget instead.

wget --content-disposition https://github.com/kastenhq/external-tools/releases/download/3.0.12/k10tools_3.0.12_linux_amd64

# Explanation of the argument 
--content-disposition        honor the Content-Disposition header when choosing local file names (EXPERIMENTAL)

Using Google Analytics to view your visitors exact referral page and landing page

Just a quick one as this was really annoying me and I have to click around to remember how to find the info each time.

The Issue

When viewing my page stats in JetPack on WordPress, I can see referrals from forums such as from Veeam, but I’ve no idea why I’m getting hits, is someone sharing my content on there?

referrals jetpack

This is the way

I’ve setup Google Analytics to give me further information on the traffic to my site. See this blog post here.

Once logged into the Google Analytics homepage and data is collecting.

  1. Go to Acquisition
  2. Expand All Traffic
  3. Click Referrals
  4. Set the time frame you’re interested in
  5. Either search for your referrer and then click on the referrer

Google Analytics referrals

Below I’ve clicked to limit the views to the referral traffic source as “forums.veeam.com”.

You can click the highlighted source filter to change to the various referral listings. At the bottom I can see which page the users visited my website from, rather than just the high-level domain.

Clicking the little outbound link symbol will take you to the exact referral page.

Google Analytics referrals filtered

You can also change this view to show you the landing page on your website, so where did the user go to.

Under Primary dimension (above your referral paths), change the setting for Other to Landing Page.

Google Analytics - primary dimension - landing page

Hope this helps!

Deploying the VMware Appliance for [email protected] using Terraform

To simplify the deployment of [email protected] appliances to vSphere environments, I have wrote a set of Terraform configuration files (script).

You will need two packages downloaded to your jump host.

And either download locally the VMware [email protected] Appliance, or host it at remote location.

Use the git software to download my Terraform Git folder which contains the folder called Deploy-FAH.

git clone https://github.com/saintdle/Terraform.git

Move into the “Deploy-FAH” folder, and edit the terraform.tfvars file as needed;

cd Deploy-FAH
vi terraform.tfvars

Below is an example;

// Name of the vSphere server. E.g "vcsa.vmware.local"
vsphere_server = "vcenter.veducate.local"

// User on the vSphere server. E.g "administrator@vsphere.local"
vsphere_user = "administrator@vsphere.local"

// Password of the user on the vSphere server. E.g "password"
vsphere_password = "Password1234!"

// Name of the vSphere data center. E.g "datacenter"
vsphere_datacenter = "Datacenter"

// Name of the vSphere cluster. E.g "Cluster"
vsphere_cluster = "Cluster"

// Name or IP of the vSphere host in the cluster to deploy your VM to. E.g "esxi-01" or "192.168.1.20"
vsphere_host = "10.10.2.4"

// Name of the vSphere data store to use for the VMs. E.g "VSAN"
vsphere_datastore = "Datastore"

// Network to connect virtual machine
vm_network = "Freale_NW1"

// Number of instances to deploy
instance_count = 2

// VM Machine Name (an index will be appended i.e FAH-1, FAH-2,)
vm_name = "dean-test"

// Number of CPUs to set on deployed Virtual Machines
num_cpu = 2

// Memory to set on deployed Virtual Machines (in MB)
memory = 4096

// Name of vSphere Resouce Pool to be created. E.g "FAH-VMs"
vsphere_resource_pool = "dean-test"

// Name of VM folder to be created. E.g "FAH-VMs"
vsphere_vm_folder = "dean-test"

// Location of OVA file if using a local location - if using remote location, leave this as null
local_ovf_path = "/home/dean/Deploy-FAH-3/VMware-Appliance-FaH_1.0.4.ova"

// Location of OVA file if using a remote location - if using local location, leave this as null
remote_ovf_path =

// Enable SSH in FAH Appliance (True or False)
ssh_enable = "True"

// FAH appliance root password
root_password = "VMware1!"

// FAH Username you wish to be associated with in the statistics tables
fah_user = ""

// FAH Team you wish to be associated with in the statistics tables
fah_team = "52737"

// FAH Passkey to verify your user in the statistical tables (this is optional from FAH project)
fah_passkey = "unique_id"

That’s it, no more changes needed, it’s as simple as running the following to deploy your appliances;

#This will download the terraform providers as needed

terraform init

#This will show you the planned changes and make sure they are possible

terraform plan

#This will run the configuration to run the deployment

terraform apply

You can use the latest version of Terraform, version 0.13.5 as of the publishing of this post.

Quick notes

This terraform configuration uses some advance configuration in the folder “FAH-Appliance”, under the main.tf file. Here it reads the “remote_ovf_path” variable, and acts based on if it is null or not. If there is a variable set, then it runs the command to deploy from a remote location. If variable is null, then it looks to the “local_ovf_path”, and processes this to deploy an OVF/OVA from the local location.

  dynamic "ovf_deploy" {
  for_each = "${var.local_ovf_path}" != "" || "${var.remote_ovf_path}" != "" ? [0] : []
  content {
  // Path to local or remote ovf/ova file
  local_ovf_path = "${var.local_ovf_path}" != "" ? "${var.local_ovf_path}" : null
  remote_ovf_url = "${var.remote_ovf_path}" != "" ? "${var.remote_ovf_path}" : null
   disk_provisioning    = "thin"
   ovf_network_map = {
        "VM Network" = data.vsphere_network.network.id
    }
   }
  }

Thanks to Grant Orchard from HashiCorp helping me with this part of the config.

Interesting in where you can take this further, check out this post from Robert Jenson, using VMware CodeStream for an Infrastructure as Code deployment using GitHub as a source repository, and terraform for the deployment.
