|
|
* Debian 11
|
|
|
|
## Install
|
|
|
|
```bash
|
|
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
|
|
|
|
|
|
## Usage
|
|
|
|
### 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
|
|
```
