#Convert a jekyll markdown post to a gophermap
#Will create a sub-directory with the name of the post and a gophermap
#converted to  70 columns with links. Tries to do basic http or gopher
#linking. May not work well, but works well enough.

# usage: ./md2gophermap.sh ../_posts/post-to-convert.md

#Know Bugs
#Pandoc does not wrap code blocks to the columns length and will get cut

Tenant IPs

• tenant IPs are stored in ips.txt
• These are used to create the number of services and the number of replicas for a statefulset (1 tenantip = 1 pod)

Create Services

• Running ./update-service.sh a for the first time will create the services
• The files ips.txt contains the list of clusterIPs to set, which also creates a label and selector
• Passing an a or b will update the selector to use the pods in group a or b
