robbertkl/base-s6 repository overview

⁠robbertkl/base-s6

Base image extension with s6-overlay:

• Based on robbertkl/base⁠
• Uses s6-overlay⁠
• Runs cron and rsyslogd services
• Helper service to output arbitrary logs to stdout or stderr
• Basic SSL certificate preparation

⁠Usage

Just extend it in your Dockerfile using FROM. Example:

FROM robbertkl/base-s6

RUN cleaninstall package1 package2 package3
RUN echo /var/log/custom.log >> /etc/services.d/logs/stderr

...

⁠Logging

To have your custom logs show up in docker logs, you can append your name to either /etc/services.d/logs/stdout or /etc/services.d/logs/stderr.

⁠SSL

As a convention, please copy or mount your SSL files to /private/ssl named cert.pem, key.pem and ca.pem. A default (snakeoil) certificate will be provided as a fallback. Create custom (combined) pem bundles from these files in your s6 run scripts.

Alternatively, you can mount a Let's Encrypt configuration to /etc/letsencrypt and set LETSENCRYPT_HOST to the hostname of the certificate to use. Symlinks with the correct names will then be create in /private/ssl.
