Portal change/rename the existing portal_domain name

Products

• CA API Developer Portal

Issue/Introduction

The customer needs to change/rename the existing portal_domain name as far as I know it is not possible to change the portal name.  The problem is just that value for PORTAL_DOMAIN was incorrectly entered during the original installation. The existing installation with incorrect portal domain name has been running for over a year; and they have lots of data.  They are now moving to DNS server and would need to change the portal_domain name.
*.t.ht.hr         - WRONG
*.dc.ht.hr - OK

The customer wants to do the following:
1) export Portal & Tenant configuration,
2) delete Portal & Tenant
3) delete enroll data on GW
4) install new Portal & Tenant with a good configuration
5) import old Portal & Tenant configuration
6) enroll with GW
Basically, the customer wants to rename the tenant name.
At the moment, there is no procedure how to delete Portal Tenant.

Environment

Release : 4.2

Component : API PORTAL

Resolution

You can update config to new host name. You can change portal host name by modifying /opt/apim-portal-4.2.9.1-final/config.sh; however, it is not possible to change the tenant id.
All ephemeral containers will switch to new host within a stack. There are few entries in the database however, that we use for cors as well as redirect to papi.
Are you running MySQL or postgres?
For gateway enrollment, this is also optional step, all the sync routes are in the cluster-wide properties, you just have to make sure marching outbound SSL cert Is imported after pointing it to new host.

Setting up proxy for url rewrite and ssl termination in front of the on-prem portal to mimic our custom domain feature in saas.

We can provide sample entry for ngnix on what needs to be changed in the rewrite rule. This is probably the best approach tried and tested in the field.

Here is a sample entry for ngnix in the rewrite rule?

server {
listen 8443 ssl;
server_name {{ (env "DOMAIN") }};
server_tokens off;
ssl_certificate /etc/nginx/conf.d/{{ (env "DOMAIN") }}.crt;
ssl_certificate_key /etc/nginx/conf.d/{{ (env "DOMAIN") }}.key;
set $my_host {{ (env "TENANT_URL") }};

# Include real_ip block
include /etc/nginx/real_ip.conf;

# Proxy Headers
proxy_set_header HOST $my_host;
proxy_set_header ORIGIN $scheme://$my_host;
proxy_set_header REFERER $scheme://$my_host;
include /etc/nginx/proxy_headers.conf;
location / {
proxy_pass https://127.0.0.1:8443$request_uri;
proxy_redirect $scheme://$my_host/ $scheme://$http_host/;
}
}
