# TLS Certificates
|
||
|
|
|
||
|
|
## Trusting the Authority
|
||
|
|
|
||
|
|
With a standard installation, the authority used to sign certificates generated in the Caddy container is not trusted by your local machine.
|
||
|
|
You must add the authority to the trust store of the host :
|
||
|
|
|
||
|
|
```
|
||
|
|
# Mac
|
||
|
|
$ docker cp $(docker compose ps -q caddy):/data/caddy/pki/authorities/local/root.crt /tmp/root.crt && sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /tmp/root.crt
|
||
|
|
# Linux
|
||
|
|
$ docker cp $(docker compose ps -q caddy):/data/caddy/pki/authorities/local/root.crt /usr/local/share/ca-certificates/root.crt && sudo update-ca-certificates
|
||
|
|
# Windows
|
||
|
|
$ docker compose cp caddy:/data/caddy/pki/authorities/local/root.crt %TEMP%/root.crt && certutil -addstore -f "ROOT" %TEMP%/root.crt
|
||
|
|
```
|
||
|
|
|
||
|
|
## Using Custom TLS Certificates
|
||
|
|
|
||
|
|
By default, Caddy will automatically generate TLS certificates using Let's Encrypt or ZeroSSL.
|
||
|
|
But sometimes you may prefer using custom certificates.
|
||
|
|
|
||
|
|
For instance, to use self-signed certificates created with [mkcert](https://github.com/FiloSottile/mkcert) do as follows:
|
||
|
|
|
||
|
|
1. Locally install `mkcert`
|
||
|
|
2. Create the folder storing the certs:
|
||
|
|
`mkdir docker/caddy/certs -p`
|
||
|
|
3. Generate the certificates for your local host (example: "server-name.localhost"):
|
||
|
|
`mkcert -cert-file docker/caddy/certs/tls.pem -key-file docker/caddy/certs/tls.key "server-name.localhost"`
|
||
|
|
4. Add these lines to the `./docker-compose.override.yml` file about `CADDY_EXTRA_CONFIG` environment and volume for the `caddy` service :
|
||
|
|
```diff
|
||
|
|
caddy:
|
||
|
|
+ environment:
|
||
|
|
+ CADDY_EXTRA_CONFIG: "tls /etc/caddy/certs/tls.pem /etc/caddy/certs/tls.key"
|
||
|
|
volumes:
|
||
|
|
+ - ./docker/caddy/certs:/etc/caddy/certs:ro
|
||
|
|
- ./public:/srv/app/public:ro
|
||
|
|
```
|
||
|
|
5. Restart your `caddy` container
