Overview

This deploys the Juju SVG web service. This service, when deployed, will generage SVGs once fed a valid bundle.

Usage

This charm is mostly standalone and self contained.

juju deploy charm-svg
juju expose charm-svg

Once deployed and exposed, any web requests can be made against the HTTP endpoint to generate an SVG.

Resources and Upgrading

This charm makes use of resources, a feature only available in Juju 2.0. During deploy or at upgrade time you can replace the following resources for newer ones:

python-jujusvg

This is the binary used to generate the SVGs given a bundle. The python-jujusvg builds upon the jujusvg project and is available on Github.

juju deploy --resource python-jujusvg=./python-jujusvg charm-svg

or

juju upgrade-charm charm-svg --resource python-jujusvg=./python-jujusvg

webapp

A tar.gz archive of the svg.juju.solutions web application this web application is used to interpret web requests and generate the SVG

juju deploy --resource webapp=./app.tar.gz charm-svg

or

juju upgrade-charm charm-svg --resource webapp=./app.tar.gz

Scale out Usage

This charm easily scales by placing a load balancer in front of charm-svg. One example is HAProxy

juju deploy haproxy
juju add-relation charm-svg haproxy
juju unexpose charm-svg
juju expose haproxy

However, there are several viable loadbalancing options
