Update the wordpress example

[yomovh]

• Add private network
• Update documentation to access to wordpress backoffice

[scraly]

Hi,
thanks for the PR.

First things, can you fix the conflicts?

Also, I added several suggestions and remarks, please take a look at them.

By the way, in the README file I recommend also to change "Mysql" to "MySQL"
Finally, the schema displayed in the README file, does not reflect the actual use case (it seems that there is no Prometheus, Grafana, Fluentd, Opensearch and M3DB) & resources are running in a private network can you edit it?

And, the most important, the example is currently not working for me, when I'm trying to deploy the Kubernetes cluster:

$ terraform apply -var-file=../variables_01.tfvars -auto-approve

data.openstack_networking_network_v2.ext_net: Reading...
data.openstack_networking_network_v2.ext_net: Read complete after 2s [id=6c928965-xxxx-xxxx-xxxx-6d4a152e9745]

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the
following symbols:
  + create
 <= read (data resources)

Terraform will perform the following actions:

  # data.ovh_cloud_project_kube_nodepool_nodes.nodes will be read during apply
  # (config refers to values not yet known)
 <= data "ovh_cloud_project_kube_nodepool_nodes" "nodes" {

Thanks

[yomovh]

I have made a change in the content by removing as suggested the dependency towards openstack provider.

The requested changes have normally been adressed (since I updated the content, I may have missed some).

Thanks for the review.

[philippart-s]

@yomovh can you clarify (by closing the request with a comment) when you don't want to apply @scraly's suggestion to have a more readable PR for people like me that comes at the end of the PR (this lets me know if the changes are completed or not).

The main point mentioned by @scraly was that the code wasn't executing, is that fixed with your updates?

[yomovh]

Hello,

@philippart-s
It was already running fine on my machine ;-) though the pre requisites list was quite long. This is why I took the remark to remove the openstack provider dependency which should lead to an easier reproducibility.

As you suggested I also closed the comments that I took into account (see my comment)

[philippart-s]

thanks, it's easier for me to valid the PR 😉

[philippart-s]

🚀, @yomovh if it's ok for you I'll merge this PR

@scraly fell free to open issues if I missed some points 😉
