I have set up a wordpress multisite through bitnami on google cloud. I do have trouble finding the proper DNS settings for subdomains though. My A record points to a static ip and resolves well. I have also created a CNAME record with the name *.mydomain.com and the value @. I was hoping this would enable subdomains on my site.
It is highly impractical to create a A or CNAME record for every subdomain as I need my users to create their own sites (subdomains) and have them available instantly.
What do I need to do to enable resolution of subdomains with a wildcard record in my DNS settings?
Thank you very much.
