SSL

Woodpecker supports two ways of enabling SSL communication. You can either use Let's Encrypt to get automated SSL support with renewal or provide your own SSL certificates.

Let's Encryptโ€‹

Woodpecker supports automated SSL configuration and updates using Let's Encrypt.

You can enable Let's Encrypt by making the following modifications to your server configuration:

WOODPECKER_LETS_ENCRYPT=true
WOODPECKER_LETS_ENCRYPT_EMAIL=ssl-admin@example.tld

Note that Woodpecker uses the hostname from the WOODPECKER_HOST environment variable when requesting certificates. For example, if WOODPECKER_HOST=https://example.com is set the certificate is requested for example.com. To receive emails before certificates expire Let's Encrypt requires an email address. You can set it with WOODPECKER_LETS_ENCRYPT_EMAIL=ssl-admin@example.tld.

The SSL certificates are stored in $HOME/.local/share/certmagic for binary versions of Woodpecker and in /var/lib/woodpecker for the Container versions of it. You can set a custom path by setting XDG_DATA_HOME if required.

Once enabled you can visit the Woodpecker UI with http and the HTTPS address. HTTP will be redirected to HTTPS.

Certificate Cacheโ€‹

Woodpecker writes the certificates to /var/lib/woodpecker/certmagic/.

Certificate Updatesโ€‹

Woodpecker uses the official Go acme library which will handle certificate upgrades. There should be no addition configuration or management required.

SSL with own certificatesโ€‹

Woodpecker supports SSL configuration by mounting certificates into your container.

WOODPECKER_SERVER_CERT=/etc/certs/woodpecker.example.com/server.crt
WOODPECKER_SERVER_KEY=/etc/certs/woodpecker.example.com/server.key

Certificate Chainโ€‹

The most common problem encountered is providing a certificate file without the intermediate chain.

LoadX509KeyPair reads and parses a public/private key pair from a pair of files. The files must contain PEM encoded data. The certificate file may contain intermediate certificates following the leaf certificate to form a certificate chain.

Certificate Errorsโ€‹

SSL support is provided using the ListenAndServeTLS function from the Go standard library. If you receive certificate errors or warnings please examine your configuration more closely.

Running in containersโ€‹

Update your configuration to expose the following ports:

docker-compose.yaml
 version: '3'

services:
woodpecker-server:
[...]
ports:
+ - 80:80
+ - 443:443
- 9000:9000

Update your configuration to mount your certificate and key:

docker-compose.yaml
 version: '3'

services:
woodpecker-server:
[...]
volumes:
+ - /etc/certs/woodpecker.example.com/server.crt:/etc/certs/woodpecker.example.com/server.crt
+ - /etc/certs/woodpecker.example.com/server.key:/etc/certs/woodpecker.example.com/server.key

Update your configuration to provide the paths of your certificate and key:

docker-compose.yaml
 version: '3'

services:
woodpecker-server:
[...]
environment:
+ - WOODPECKER_SERVER_CERT=/etc/certs/woodpecker.example.com/server.crt
+ - WOODPECKER_SERVER_KEY=/etc/certs/woodpecker.example.com/server.key
