I have a array defined in the following format in hiera.
master_servers: - "stage-01.com" - "stage-02.com"
I am trying to populate the config file with ERB in the following format
discovery.zen.ping.unicast.hosts: ["stage-01.com", "stage-02.com" ]
I tried the following in ERB, but the array comes off as a single string.
discovery.zen.ping.unicast.hosts: <%= scope['::profiles::xxx::master_servers'] %>
profiles::xxx::master_servers is correctly doing the hiera lookups.
How can I correct my ERB?
