title: CertWarden-Deploy
type: docs

[CertWarden](https://www.certwarden.com/) is a self-hosted Centralized ACME Certificate Management platform. With it you can manage and aquire Let's Encrypt certificates.

However, to deploy them to your hosts, for now there only was a docker client, and that was too bloated for me.

So I built `certwarden-deploy`, a dependency-less binary that can run via crontab/systemd timers and that can fetch new certificates and run actions after new certificates got rolled out.

## Quick Start

Installation of the required CertWarden instance is out of scope of this documentation. For detailed instructions regarding CertWarden, please visit [it's documentation](https://www.certwarden.com/docs/introduction/)


To quickly get started with `certwarden-deploy`, just download the binary...

```shell
# this downloads certwarden-deploy version 0.2.1
# to /usr/local/bin/certwarden-deploy
sudo wget https://code.lila.network/adoralaura/certwarden-deploy/releases/download/0.2.1/certwarden-deploy-0.2.1-linux-amd64 -O /usr/local/bin/certwarden-deploy

sudo chmod +x /usr/local/bin/certwarden-deploy
```

... fill out the config file...
```shell
vi /etc/certwarden-deploy/config.yaml
```
```yaml
# Base URL of the CertWarden instance
# required
base_url: "https://certwarden.example.com"

# Set this to true if your CertWarden instance does not have a publicly trusted 
# TLS certificate (e.g. it has a self signed one)
# default is false
disable_certificate_validation: false

# define all managed certificates here
certificates:

    # name is a unique identifier that must start and end with an alphanumeric character, 
    # and can contain the following characters: a-zA-Z0-9._-
    # required
  - name: test-certificate.example.com

    # Contains the API-Key to fetch the certificate from the server
    # required
    cert_secret: examplekey_notvalid_hrzjGDDw8z

    # path where to save the certificate
    # required
    cert_path: "/path/to/test-certificate.example.com-cert.pem"

    # Contains the API-Key to fetch the private key from the server
    # required
    key_secret: examplekey_notvalid_hrzbbDDw8z

    # path where to save the private key
    # required
    key_path: "/path/to/test-certificate.example.com-key.pem"

    # action to run when certificate was updated or --force is on
    action: "/usr/bin/systemd reload caddy"
```

... and run it!
```shell
certwarden-deploy -v
```

configuration, setup, and tips. If you have something
that works and is not in the repository, please pay it forward and
share what works.
