Processing JSON using jq

jq is useful to slice, filter, map and transform structured json data.

kubectl multi-version brews

We need to run multiple versions of kubectl for compatibility with various kubernetes clusters.

It's a bit easier to get and use multiple versions of kubectl using Homebrew than it is using Macports.

With brew, it's simple to:

• Install a bunch of versions of kubectl (in the kubernetes-cli Formula)
• Switch between them as needed

Update environment and volume sections in docker-compose.yaml

To get a valid certificate but not allow external access to the service see https://github.com/jwilder/nginx-proxy#internet-vs-local-network-access

Requirements docker-compose.yaml:

• nginx-proxy must be publicly reachable on both port 80 and 443.
• Check your firewall rules/port forwards and do not attempt to block port 80 as that will prevent http-01 challenges from completing.
• For the same reason, you can't use nginx-proxy's HTTPS_METHOD=nohttp.
• The (sub)domains you want to issue certificates for must correctly resolve to the host.
• Your DNS provider must answer correctly to CAA record requests.
