Molecule Logs: [Short](https://badges.ansibleguy.net/log/molecule_infra_certs_test_short.log), [Full](https://badges.ansibleguy.net/log/molecule_infra_certs_test.log)
**Tested:**
* Debian 11
* Debian 12
## Install
```bash
# latest
ansible-galaxy role install git+https://github.com/ansibleguy/infra_certs
# from galaxy
ansible-galaxy install ansibleguy.infra_certs
# or to custom role-path
ansible-galaxy install ansibleguy.infra_certs --roles-path ./roles
# install dependencies
ansible-galaxy install -r requirements.yml
```
## Functionality
* **Package installation**
* Ansible dependencies (_minimal_)
* Crypto Dependencies
* **Configuration**
* **Four Possible Modes**:
* Generate **Self-Signed** certificate
* Use a **minimal Certificate Authority** to create signed certificates
* Configure **LetsEncrypt-Certbot** to generate publicly valid certificates
* Supported for Nginx and Apache
* Host needs to have a valid public dns record pointed at it
* Needs to be publicly reachable over port 80/tcp
* **Default config**:
* Mode => Self-Signed
## Info
* **Note:** this role currently only supports debian-based systems
* **Note:** Most of the role's functionality can be opted in or out.
For all available options - see the default-config located in the main defaults-file!
* **Note:** If you have the need to **mass manage certificates** - you might want to check out the [ansibleguy.infra_pki](https://github.com/ansibleguy/infra_pki) role that enables you to create and manage a full **P**ublic **K**ey **I**nfrastructure.
* **Note:** The certificate file-name (_name variable as defined or else CommonName_) will be updated:
* spaces are transformed into underlines
* all Characters except "0-9a-zA-Z." are removed
* the file-extension (_crt/chain.crt/key/csr_) will be appended
* **Warning:** Not every setting/variable you provide will be checked for validity. Bad config might break the role!
* **Info:** For LetsEncrypt renewal to work, you must allow outgoing connections to:
80/tcp, 443/tcp+udp to acme-v02.api.letsencrypt.org, staging-v02.api.letsencrypt.org (_debug mode_) and r3.o.lencr.org

### Notes
The **self-signed and minimal-ca** modes will only create a single certificate per run.
Re-runs can save some overhead by using the 'certs' tag.
The **LetsEncrypt** mode will create/remove multiple certificates as defined.
### Config
Example for LetsEncrypt config:
```yaml
certs:
mode: 'le_certbot'
path: '/etc/apache2/ssl'
letsencrypt:
certs:
myNiceSite:
domains: ['myRandomSite.net', 'ansibleguy.net']
email: 'certs@template.ansibleguy.net'
service: 'apache'
```
Example for Self-Signed config:
```yaml
certs:
mode: 'selfsigned'
# choose 'ca' instead if you use dns-names
# some browsers won't let you connect when using self-signed ones
path: '/etc/nginx/ssl'
group_key: 'nginx'
owner_cert: 'nginx'
cert:
cn: 'My great certificate!'
org: 'AnsibleGuy'
country: 'AT'
email: 'certs@template.ansibleguy.net'
domains: ['mySoGreat.site', 'ansibleguy.net']
ips: ['192.168.44.2']
pwd: !vault ...
```
Example for minimal-CA config:
```yaml
certs:
mode: 'ca'
path: '/etc/ca/certs'
mode_key: '0400'
cert:
name: 'custom_file_name' # extension will be appended
cn: 'My great certificate!'
org: 'AnsibleGuy'
country: 'AT'
email: 'certs@template.ansibleguy.net'
domains: ['mySoGreat.site', 'ansibleguy.net']
ca:
path: '/etc/ca'
cn: 'SUPER CertificateAuthority'
org: 'AnsibleGuy'
country: 'AT'
email: 'certs@template.ansibleguy.net'
pwd: !vault ...
```
Using the minimal-CA you can create multiple certificates signed by the CA by re-running the role with changed 'cert' settings.
You might want to use 'ansible-vault' to encrypt your passwords:
```bash
ansible-vault encrypt_string
```
### Execution
Run the playbook:
```bash
ansible-playbook -K -D -i inventory/hosts.yml playbook.yml --ask-vault-pass
```
There are also some useful **tags** available:
* certs => ignore ca tasks; only generate certs
* selfsigned
* config
* certs
To debug errors - you can set the 'debug' variable at runtime:
```bash
ansible-playbook -K -D -i inventory/hosts.yml playbook.yml -e debug=yes
```
