Benoît Knecht c078513475 ceph-rgw-loadbalancer: Fix rgw_ports fact
The `set_fact rgw_ports` task was failing due to a templating error, because
`hostvars[item].rgw_instances` is a list, but it was treated as if it was a
dictionary.

Another issue was the fact that the `unique` filter only applied to the list
being appended to `rgw_ports` instead of the entire list, which means it was
possible to have duplicate items.

Lastly, `rgw_ports` would have been a list of integers, but the `seport` module
expects a list of strings.

This commit fixes all of the issues above, allowing the `ceph-rgw-loadbalancer`
role to work on systems with SELinux enabled.

Guillaume Abrioux d0442d81b9 common: selinux tasks related refactor
This moves some task from the `ceph-nfs` role in `ceph-common` since
some of them are needed in `ceph-rgwloadbalancer` role.
This avoids duplicated tasks.

Guillaume Abrioux 6bbb90198b rgw-loadbalancers: add all rgw_ports to http_port_t type
This adds all rgw ports to the http_port_t selinux type so it
allows haproxy to connect to those ports in order to avoid AVC.

Alex Schultz a7f2fa73e6 Use ansible_facts
It has come to our attention that using ansible_* vars that are
populated with INJECT_FACTS_AS_VARS=True is not very performant.  In
order to be able to support setting that to off, we need to update the
references to use ansible_facts[<thing>] instead of ansible_<thing>.

Benoît Knecht 3116f46422 ceph-rgw-loadbalancer: Fix keepalived master selection
While 2ca33641 fixed a bug in the way the `keepalived.conf.j2` template matched
hostnames to set the VRRP `MASTER`/`BACKUP` states, it also introduced a
regression in the case where `virtual_ips` is a list of more than one IP
address.

The previous behavior would result in each host in the `rgwloadbalancers` group
to be `MASTER` for one of the `virtual_ips`, but the new behavior caused the
first host to be `MASTER` for all the IP address in `virtual_ips`.

This commit restores the original behavior.

Niko Smeds a951c1a3f0 Enable HAProxy backend checks for Ceph RGW
Add the `check` option to server definitions to enable basic HAProxy health
checks for Ceph RADOS gateway backends.

Currently traffic will be forwarded to unhealthly `radosgw.service` servers.
These changes resolve the issue.

Ansible Deployment User 3f906e0c26 rgwloadbalancer undefined index variable
The vrrp_instances variable is using a loop with index but the index_var
wasn't defined.
As a result, the fact task was failing on this undefined index variable.

The task includes an option with an undefined variable. The error was:
'index' is undefined

Florian Faltermeier 9d081e2453 ceph-rgw-loadbalancer: Fix SSL newline issue
The ad7a5da commit introduced a regression when using TLS on haproxy
via the haproxy_frontend_ssl_certificate variable.
This cause the "stats socket" and the "tune.ssl.default-dh-param"
parameters to be on the same line resulting haproxy failing to start.

Stanley Lam 2ca3364109 ceph-rgw-loadbalancer: Modify keepalived master selection
Currently the keepalived template only works when system hostnames exactly match the Ansible inventory name. If these are different, all generated templates become BACKUP without a MASTER assigned. Using the inventory_hostname in the template file resolves this issue.

guihecheng 35d40c65f8 Add role definitions of ceph-rgw-loadbalancer
This add support for rgw loadbalancer based on HAProxy and Keepalived.
We define a single role ceph-rgw-loadbalancer and include HAProxy and
Keepalived configurations all in this.

A single haproxy backend is used to balance all RGW instances and
a single frontend is exported via a single port, default 80.

Keepalived is used to maintain the high availability of all haproxy
instances. You are free to use any number of VIPs. A single VIP is
shared across all keepalived instances and there will be one
master for one VIP, selected sequentially, and others serve as
backups.
This assumes that each keepalived instance is on the same node as
one haproxy instance and we use a simple check script to detect
the state of each haproxy instance and trigger the VIP failover
upon its failure.
