* Add k8s_allowed_remote_ips variable
Useful for defining CIDRs allowed to initiate a SSH connection when
you don't want to use a bastion.
* Add TF_VAR_k8s_allowed_remote_ips variable to tf-apply-ovh
* [contrib/terraform/openstack] Add worker_allowed_ports
Allow user to define in terraform template which ports and remote
IPs that are allowed to access worker nodes. This is useful when you
don't want to open up whole NodePort range to the outside world, or
ports outside NodePort range.
* Add an 'access_ip' for openstack resources to the terraform inventory builder script
* Update Openstack README
* Only use ipv4
* If there's a floating IP assigned to an openstack instance, use that for access_ip
* Replace `openstack_compute_secgroup_v2` with `openstack_networking_secgroup_v2`
The `openstack_networking_secgroup_v2` resource allow specifications of
both ingress and egress. Nova security groups define ingress rules only.
This change will also allow for more user-friendly specified security
rules, as the different security group resources have different HCL
syntax.
Attempting to clarify the language surrounding the etcd node deployment script failure mechanism. I had this error when doing a new cluster deployment last night and, though it should have been, it wasn't immediately apparent to me what was causing the issue (since my default master node hostnames do not specify whether they are also acting as etcd replicas).
* Add supplementary node groups
To add additional ansible groups to the k8s nodes, such as
`kube-ingress` for running ingress controller pods. Empty by default.
* [terraform/openstack] Restores ability to use existing public nodes and masters as bastion.
* [terraform/openstack] Uses network_id as output
* [terraform/openstack] Fixes link to inventory/local/group_vars
* [terraform/openstack] Adds supplementary master groups
* [terraform/openstack] Updates documentation avoiding manual setups for bastion (as they are not needed now).
* [terraform/openstack] Supplementary master groups in docs.
* [terraform/openstack] Fixes repeated usage of master fips instead of bastion fips
* [terraform/openstack] Missing change for network_id to subnet_id
* [terraform/openstack] Changes conditional to element( concat ) form to avoid type issues with empty lists.
Hardcoded variables are removed from variables.tf file because it might
not be suitable for all OpenStack Cloud depending on Identity API
version available (between v2 or v3) and preferred authentication
method.
