# Hiera Environments
## Add New Hiera Environment
### Introduction
Deploying a new environment requires the following:
1. Configuring the environment in **bob**
2. Configuring the environment `data-<environment_name>` in GIT (https://gitea.psi.ch/puppet)
3. Configuring the environment in Puppet (e.g. `puppet.psi.ch`)
### Configuring the environment in sysdb
Bob allows to create a new environment in `sysdb` by using the `bob env` option.
Only members of the `unx-lx_eng` group have permissions to do so.
To list current defined environments run
bob env list
To add a new environment, run
bob env add <environment_name> <owner> <admin_group> "<description>"
In example, for the MeG cluster
bob env add meg caubet_m unx-hpc_adm "MeG Cluster"
#### Test new environment in BOB
In order to test that environment was successfully created
bob env list | grep <environment_name>
An example
caubet_m@caubet-laptop:~/GIT/admin-guide/deployment$ bob env list | grep meg
meg caubet_m unx-hpc_adm MeG Cluster
### Configuring the environment in GIT
You must belong to the `unx-puppet_adm` Active Directory group in order to be able to create new projects.
In order to create a new environment in **GIT**, you should access and login in the following link: https://gitea.psi.ch/puppet/.
Here you can see the different environments.
The steps to create and configure a new **GIT** project are:
1. Create a new repository (environment). It can be done here: https://gitea.psi.ch/repo/create?org=6
- Define `Repository name`, which *must* have the format `data-<environment_name>` where `<environment_name>` is the one defined in **Bob**
- `Visibility`: set checkbox `Make repository private`
- `Default Branch`: set it to `master`
2. Configure project permissions as follows:
- `data-<environment_name` -> `Settings` -> `Collaborators`, or directly: https://gitea.psi.ch/puppet/data-(environment_name)/settings/collaboration
- add teams with access
- if the team does not yet exists, map it from the AD group as documented in chapter "Mapping AD Groups to Teams" in our [Gitea Production Documentation](gitea-dmz)
- Enable already registered deploy key: `Settings` -> `Deploy Keys` -> `Add Deploy Key` with
- `Title`: `plidata`
- `Content`:
```

```
- for the runner configuration check out the new Hiera data repo and add `.gitea/workflows/hiera_update.yaml` from [another one](https://gitea.psi.ch/puppet/data-lx/raw/branch/master/.gitea/workflows/hiera_update.yaml).
3. Disable unnecessary Gitea features
- In `data-<environment_name` -> `Settings`, or directly: https://gitea.psi.ch/puppet/data-(environment_name)/settings:
- untick `Enable Repository Wiki`
- untick `Enable Projects`
- untick `Enable Repository Releases`
- untick `Enable Repository Packages Registry`
- click `Update Settings`
4. Add Deployment Workflow
- Add following workflow in `.gitea/workflows/hiera_update.yaml` to the repository:
```yaml
name: hiera update
on:
push:
branches:
- master
workflow_dispatch:
jobs:
puppet-deployment:
runs-on: puppet
steps:
- name: Execute hiera-update
run: |
environment="${{ github.repository }}"
echo "sudo -u plidata /opt/pli/bin/hiera-update ${environment#*data-}"
sudo -u plidata /opt/pli/bin/hiera-update ${environment#*data-}
sysdb-deployment:
runs-on: sysdb
steps:
- name: Execute hiera-update
run: |
environment="${{ github.repository }}"
echo "sudo -u plidata /opt/pli/bin/hiera-update ${environment#*data-}"
sudo -u plidata /opt/pli/bin/hiera-update ${environment#*data-}
- name: Execute hiera-extractor
run: |
environment="${{ github.repository }}"
echo "sudo -u plidata /opt/hiera-extractor/hiera-extractor ${environment#*data-}"
sudo -u plidata /opt/hiera-extractor/hiera-extractor ${environment#*data-}
```
#### Test new environment in GIT
In order to test that environment was successfully created
git clone git@gitea.psi.ch:puppet/data-<environment_name>.git
An example
$ git clone git@gitea.psi.ch:puppet/data-ems.git
Cloning into 'data-ems'...
warning: You appear to have cloned an empty repository.
### Configuring the Environment in Puppet Server and Sysdb Server
In [bootstrap](https://gitea.psi.ch/lx/bootstrap)
- add the new environment to the `sysdb_environments` list in [`ansible/group_vars/prod.yaml`](https://gitea.psi.ch/lx/bootstrap/src/branch/prod/ansible/group_vars/prod.yaml).
- To prepare the `eyaml` key go into the directory `ansible/roles/hiera_checkout/files/srv/puppet` and run
```
SYSDB_ENV=...
eyaml createkeys
mv keys/private_key.pkcs7.pem keys/${SYSDB_ENV}_private_key.pkcs7.pem
ansible-vault encrypt --vault-pass-file ../../../../../vault-pass keys/${SYSDB_ENV}_private_key.pkcs7.pem
```
and move `keys/public_key.pkcs7.pem` as `eyaml_public_key.pem` into the `data-<environment_name>` checkout and add, commit and push everything changed on both repos.
- For Puppet server run in `ansible` to deploy:
```
ansible-playbook -i inventory.yaml --vault-pass-file ./vault-pass install_puppet_server.yaml
```
- For Sysdb server run in `ansible` to deploy:
```
ansible-playbook -i inventory.yaml --vault-pass-file ./vault-pass install_sysdb.yaml
```
### Test new environment in Puppet
In order to test that environment was successfully created
git clone git@gitea.psi.ch:puppet/data-<environment_name>.git
Add a new file <environment_name>.yaml in to the project:
cd data-<environment_name>
touch <environment_name>.yaml
git add <environment_name>.yaml
git commit -a -m "Added first empty file"
git push
After a few seconds (needs time to trigger the change), check in `puppet.psi.ch:/srv/puppet/data/<environment_name>` that file was successfully triggered (copied) to the puppet server from **GIT**
ssh root@puppet.psi.ch ls /srv/puppet/data/<environment_name>/<environment_name>.yaml
Full real example:
git clone git@gitea.psi.ch:puppet/data-meg.git
cd data-meg
touch meg.yaml
git add meg.yaml
git commit -a -m "Added first empty file"
git push
sleep 5
ssh root@puppet.psi.ch ls /srv/puppet/data/meg/meg.yaml
## Remove Hiera Environment
To remove a Hiera environment following steps are required:
1. Delete Git repository for the environment (https://gitea.psi.ch/puppet/data-&lt;environment_name&gt;)
2. Remove the environment from bootstrap (https://gitea.psi.ch/lx/bootstrap) by deleting the environment from the `sysdb_environments` list in [`ansible/group_vars/prod.yaml`](https://gitea.psi.ch/lx/bootstrap/src/branch/prod/ansible/group_vars/prod.yaml)
3. Remove directory for the environment on Puppet and Sysdb server (i.e. puppet server: `/srv/puppet/data/<environment_name>`, sysdb server: `/srv/puppet/data/<environment_name>`)
4. Remove the environment from sysdb database
```bash
cd /var/www/sysdb
sqlite3 inv.db
DELETE FROM environments WHERE name = '<environment_name>';
```
