(PE-37233-35) Official support of Add compiler plan (#485)
* (PE-37236) Remove experimental status of add_compiler (#428) * (PE-37233) Adding add_compiler to test matrix (#434) Updated add_compiler spec to check compiler has been added and puppet run before running add compiler Added test matrix for add compiler * (PE-38814) add_compiler - Making primary_postgresql_host and avail_group_letter optional (#468) * (PE-38814) add_compiler - Making primary_postgresql_host and avail_group_letter optional primary_postgresql_host, if not provided will be determined through get_peadm_config avail_group_letter, is defaulting to A * Updating spec tests for add compiler Removing optional from avail_group_letter as not required with enum default value * Updating reference.md * Fixing linting issues --------- Co-authored-by: Neil Anderson <[email protected]> * (PE-37235) Verify and update documentation on add_compiler (#429) * PE-37235 Verify and update documentation on add_compiler if needed and its experimental status * @cathal41 PE-37235 Verify and update documentation on add_compiler - wording updates * Update plans/add_compiler.pp Co-authored-by: Dimitri Tischenko <[email protected]> * Update documentation/add_compiler.md Co-authored-by: Dimitri Tischenko <[email protected]> * Update documentation/add_compiler.md Co-authored-by: Dimitri Tischenko <[email protected]> * Update documentation/add_compiler.md Co-authored-by: Dimitri Tischenko <[email protected]> * Update documentation/add_compiler.md Co-authored-by: Dimitri Tischenko <[email protected]> * Update documentation/add_compiler.md Co-authored-by: Dimitri Tischenko <[email protected]> * Updating add compiler docs to show optional params * Updating docs with text corrections --------- Co-authored-by: Dimitri Tischenko <[email protected]> Co-authored-by: Neil Anderson <[email protected]> * chore(workflows): simplify YAML syntax and improve readability - Removed unnecessary quotes around strings in YAML files. - Consolidated list items to single-line format where applicable. - Ensured consistent naming conventions for job steps. - Improved readability by removing extra blank lines. * fix(workflow): add console_password to test-add-compiler workflows - Added `console_password` parameter to the `test-add-compiler-matrix.yml` and `test-add-compiler.yaml` workflows. - This ensures the console password is passed correctly during the workflow execution. * chore: update test-add-compiler-matrix workflow - Remove centos-7 from the image matrix in test-add-compiler-matrix.yml - Retain only almalinux-cloud/almalinux-8 in the image matrix * feat(workflow): add --stream option to bolt plan run command Added the --stream option to the bolt plan run command in the test-add-compiler GitHub workflow. This change ensures that the output is streamed in real-time. * chore(workflow): update compiler versions in test-add-compiler-matrix.yml Updated the compiler versions in the test-add-compiler-matrix.yml GitHub workflow from 2021.7.7 and 2023.6.0 to 2021.7.9 and 2023.8.0. --------- Co-authored-by: Jo Lillie <[email protected]> Co-authored-by: Neil Anderson <[email protected]> Co-authored-by: Neil Anderson <[email protected]> Co-authored-by: cathal41 <[email protected]> Co-authored-by: Dimitri Tischenko <[email protected]>

## Introduction
11+
12+
The `peadm::add_compiler` plan can be used to add a new compiler to a PE cluster or replace an existing one with new configuration.
13+
14+
15+
## Add a compiler to an existing PE cluster
16+
17+
As seen in the example below, this is the minimal parameters required to add a compiler to an existing PE cluster. These can be passed as command line variables to the plan, or in this case added to a params.json file.
18+
19+
```json
20+
{
21+
"compiler_host": "pe-xl-compiler-0.lab1.puppet.vm",
22+
"primary_host": "pe-xl-core-0.lab1.puppet.vm"
23+
}
24+
```
25+
26+
## Running the `add_compiler` plan
27+
```
28+
bolt plan run peadm::add_compiler --params @params.json
29+
```
30+
31+
This command will retrieve the current PEADM configuration to determine the setup rules needed for a compiler's secondary PuppetDB instances. The plan will configure the primary with appropriate rules for allowing access from the new compiler. On the primary, the `puppet` service is stopped and the `pe-postgresql` service is reloaded. If required, a puppet agent will be installed on the new compiler host. The compiler agent's certificate is regenerated to include data required by the `peadm::subplans::component_install` plan. A subsequent Puppet agent run will happen on the following components.
32+
* _\<compiler-host\>_
33+
* _\<primary_postgresql_host\>_
34+
* _\<replica host\>_
35+
* _\<primary_postgresql_host\>_
36+
37+
The `puppet` service is then restarted.
38+
39+
40+
## Optional Parameters
41+
42+
As well as `compiler_host` and `primary_host`, the `add_compiler` plan has a number of optional parameters. These can be viewed in the following params example.
43+
44+
```json
45+
{
46+
"avail_group_letter": "B",
47+
"compiler_host": "pe-xl-compiler-0.lab1.puppet.vm",
48+
"dns_alt_names": [ "puppet", "puppet.lab1.puppet.vm" ],
49+
"primary_host": "pe-xl-core-0.lab1.puppet.vm",
50+
"primary_postgresql_host": "pe-psql-6251cd-0.us-west1-a.c.slice-cody.internal"
51+
}
52+
```
53+
54+
Please note, the optional parameters and values of the plan are as follows.
55+
56+
<!-- table -->
57+
| Parameter | Default value | Description |
58+
|--------------------------|---------------|--------------------------------------------------|
59+
| `avail_group_letter` | `A` | By default, each compiler will be added to the primary group A. |
60+
| `dns_alt_names` | `undef` | |
61+
| `primary_postgresql_host`| `undef` | By default, this will pre-populate to the required value depending if your architecture contains HA and or external databases. |

116-
As was described in the section documenting [peadm::add_replica](#enable-disaster-recovery-and-add-a-replica-with-peadmadd_replica), when disaster recovery (DR) is enabled and a Replica provisioned, PEADM creates a second availability group, **B**. You must take this second availability group into consideration when adding new compilers and ensure you are assigning appropriate values for the group the Compiler is targeted for. It is a good idea to keep these two availability groups populated with an equal quantity of Compilers. Besides the value of `avail_group_letter` being dependent on which group the new Compiler is targeted towards, the value of `primary_postgresql_host` will also vary.

The name of the `primary_postgresql_host` parameter can be confusing, it is **NOT** always equal to the Primary Puppet server or Primary PE-PostgreSQL server, it can also be equal to the Replica Puppet server or Replica PE-PostgreSQL server. It should be set to the server which is a member of the Compiler's target availability group. The easiest way to determine this value is to first run the `peadm::get_peadm_config` task and source the value from its output. In the **Example** section the value to use when targeting the **B** group is `pe-server-59ab63-1.us-west1-b.c.slice-cody.internal`. You'll find the value at `role-letter.server.B`.

### Adding Compilers to Extra Large when disaster recovery has been enabled

166166
Adding a Compiler to a deployment which has adopted the Extra Large deployment architecture with disaster recovery (DR) enabled is similar to Standard and Large but the value of `primary_postgresql_host` will no longer correspond to the Primary or Replica Puppet server since PuppetDB databases are now hosted externally. In the **Example** section, the value to use when targeting the **A** group is `pe-psql-65e03f-0.us-west1-a.c.slice-cody.internal`. You'll find the value at `role-letter.postgresql.A`.
