问题
I have one nodejs web app on ibm cloud: MYAPP.eu-de.mybluemix.net.
I want it to be reachable over https on https://MYSUB.MYDOMAIN.IO
I own MYDOMAIN.IO, and added this CNAME entry in my dns provider: MYSUB.MYDOMAIN.IO. 0 CNAME MYAPP.eu-de.mybluemix.net.
I purchased a certificate for SUB.MYDOMAIN.IO added the domain in my organisation, and uploaded the certificate. Note it is not a wildcard. I read that long ago bluemix only accepted wildcards, but I could upload my single certificate without issue.
I also added the route to the app so I have 2 routes in the settings, both with the padlock green:
MYAPP.eu-de.mybluemix.net
MYSUB.MYDOMAIN.IO
After all this, when I navigate to https://SUB.MYDOMAIN.IO, I end up on the app page (redirection working), BUT I get the security warning because the certificate is still the one of bluemix, not mine.
What am I doing wrong???
回答1:
ok got it sorted after swimming in an ocean of outdated ibm doc, I found that to use custom domain, the DNS config should be a CNAME to a specific domain name. in my case, not MYAPP.eu-de.mybluemix.net but MYAPP.eu-de.cf.appdomain.cloud
This URL was always there in the list of available domain, but it was hard to find its use.
