This project is a fork of the vzic project, which implements conversion of Olson tzdata into iCalendar VTIMEZONE objects.

The original vzic readme is available here. Ultimately the conversion code is largely unchanged. This project adds the capability to serve the VTIMEZONE objects from an Apache web server.

docker build --tag tzurl .

A Docker image has been created from this project and can be run as follows:

docker run --rm -it -p 80:80 benfortuna/tzurl

A docker-compose configuration is provided that will run Apache HTTPD behind an HAProxy load balancer. This allows for scaling multiple Apache instances, etc. Examples follow.

$ docker-compose build && docker-compose up # run a single httpd instance behind haproxy

$ docker-compose scale tzurl=2 && docker-compose up # run two httpd instance load-balanced

RSyslog is supported in HAProxy. Examples below.

$ docker-compose run -d -e RSYSLOG_DESTINATION=<syslog_host:port> haproxy && docker-compose up

$ docker-compose scale tzurl=2 && docker-compose run --service-ports -d -e RSYSLOG_DESTINATION=<syslog_host:port> haproxy
