mapproxy-docker

TL;DR

docker build -t pdok/mapproxy .
docker run --rm -d -p 8080:80 --name mapproxy-example -v `pwd`/examples/config/mapproxy.yaml:/srv/mapproxy/config/mapproxy.yaml pdok/mapproxy

docker stop mapproxy-example

Introduction

This project aims to fulfill the need for creating a Docker base image that can be used in a scalable infrastructure like Kubernetes and still is easy to use with a single docker run command. That's why we created this docker images containing in which we don't COPY config during the docker build.

What will it do

In it simplist form it will create an Mapproxy application that is easy to use. The only thing required is to add you own mapproxy.yaml configuration. For more complex deployments like docker-compose and/or kubernetes it will provide a starting point in creating multi-container/pods deployments.

Usage

Build

docker build -t pdok/mapproxy .

Run

This image can be run straight from the commandline. The mapproxy config file needs to be mounted on the container path /srv/mapproxy/config/mapproxy.yaml.

docker run -d -p 80:80 --name mapproxy-example -v `pwd`/examples/config/mapproxy.yaml:/srv/mapproxy/config/mapproxy.yaml pdok/mapproxy

Running the example above will start a empty mapproxy. On the url http://localhost:8080/mapproxy/demo the test page can be accessed. Replacing the example mapproxy.yaml with your own will start a mapproxy with that configuration.

This docker image uses lighttpd as a proxy. It's possible to add additional lighttpd config by mounting a include.conf file on the container path /srv/mapproxy/config/include.conf. It's also possible to provide your own complete lighttpd config by mounting a lighttpd.conf file on the container path /srv/mapproxy/config/lighttpd.conf.

Environment variables

DEBUG Set the log level for both lighttpd and mapproxy to debug. This results is verbose logging which includes in request logging (Default: 0)

MIN_PROCS Sets the minimum fastcgi processes to start (Default: 4)

MAX_PROCS Upper limit of fastcgi processes to start (Default: 8)

MAX_LOAD_PER_PROC Maximum number of waiting processes on average per process before a new process is spawned (Default: 1)

IDLE_TIMEOUT Number of seconds before a unused process gets terminated (Default: 20)
