Lab 16.1

gavsdavs

Requirement: Deploy a load balancer configured to pass through traffic on your new proxy node. HAProxy is easy to deploy using online documentation. Start with forwarding traffic of the cp alias to just the working cp

Does this mean a add a node as a standalone VM, or does it mean add it as a worker node and then put a haproxy deployment onto this node ?

I'm aware this lab is asking you to go back over notes to work out how to add the new control-plane nodes but the wording here is poor.

The lab needs to be more specific in what it wants us to do.

It also does not state which ports we want the haproxy service to be forwarding to the existing cp node.

Does anyone have any more detail ?

Hi @gavsdavs,

The HA Proxy is deployed as a stand-alone VM.

According tho the instructions in lab exercise 16.1:

You will need three more nodes. One to act as a load balancer, the other two will act as cp nodes for quorum.

There is also a table that suggests there are three additional VMs required.

Lab exercise 16.2 on Step 2 displays a snippet of the haproxy.cfg file of the HA Proxy server, with the suggested edits that include the required hostnames of the cp, cp2 and cp3 nodes, their respective IP addresses and secure ports. The same file, completed and formatted can be retrieved from the SOLUTIONS tarball under the s_16 subdirectory (that needs minimal updates before the haproxy service restart).

Regards,

Yeah i found this in the solutions tarball - i missed that in the notes earlier.
