Images referenced in graphviz output aren't able to be exported to the current directory
Using the cfn-graph tool after installing it with something like npm install --save cloudformation-graph --global has the referenced images in the generated graphviz output available at a path like this:
"ApplicationLoadBalancer" ["label" = < <table border="0" cellborder="0"><tr><td fixedsize="true" width="30" height="30">
<img src="/Users/mark.campbell/.nvm/versions/node/v11.7.0/lib/node_modules/cloudformation-graph/lib/icons/networkingcontentdelivery_elasticloadbalancing_applicationloadbalancer.png"/>
</td><td>ApplicationLoadBalancer</td></tr></table> >];
When this happens, I would have to manually find all of the referenced images and copy them around so that I can export it in a sane manner to wherever I need.
A more ideal scenario would be if I could supply a command line option to output all necessary image dependencies to a local directory and the graphviz output would use that relative path instead of a absolute path. i.e., a images/ directory with networkingcontentdelivery_elasticloadbalancing_applicationloadbalancer.png is created and the graphviz output uses that relative path.
The use case where I ran into this was because I cannot install graphviz on my Mac OS X Mojave install due to homebrew issues with removing options in homebrew-core formulas and a lack of support for graphviz on Mojave:
- Graphviz.app currently doesn’t build on OSX Mojave because of Apple API changes. It would be wonderful if someone can fix this.
So I opted to run graphviz in a docker container and the referenced images don't exist, so the dot invocation fails.
GraphViz now supports Mojave: https://gitlab.com/graphviz/graphviz/issues/1515
