nginx configuration is broken when multiple applications with the same name are created under different domains
Last modified: 2016-01-31 21:36:48 EST
Description of problem: The openshift routing nginx configuration for HA applications is partially broken when two applications with the same name are created under different domains. Specifically, the conf.d/server.conf will have two entries pointing to the same endpoint, throwing the below error when nginx is restarted: nginx: [emerg] duplicate location "/test10" in /opt/rh/nginx16/root/etc/nginx/conf.d/server.conf:78 Version-Release number of selected component (if applicable): OSE 2.2.0 rubygem-openshift-origin-routing-daemon-0.17.1.4-1.el6op.noarch How reproducible: Always Steps to Reproduce: 1. Set up and configure an HA load balancer for applications 2. Create two applications under seperate domains with the same name 3. Actual results: Two entries are created in conf.d/server.conf. For the below example, the app name is 'test10' and the two domains are 'tim' and 'admin': # route_name=route_ose_test10_admin location /test10 { proxy_pass http://pool_ose_test10_admin_80; } # route_name=route_ose_test10_tim location /test10 { proxy_pass http://pool_ose_test10_tim_80; } Expected results: Endpoint added without issue Additional info: Are these endpoints really necessary?
Fixed upstream, opened PR https://github.com/openshift/origin-server/pull/5985 Will merge to enterprise-server
Verified this bug with rubygem-openshift-origin-routing-daemon-0.20.2.4-1.el6op.noarch, and PASS. 1. Acreate two scalable apps, no endpoint will be added into server.conf, the following conf file are built. # cat server.conf ssl_certificate /etc/pki/tls/certs/node.example.com.crt; ssl_certificate_key /etc/pki/tls/private/node.example.com.key; server { listen 80 default_server; server_name _; location / { return 404; } } server { listen 443 ssl default_server; server_name _; location / { return 404; } }
Typo in comment 7, should be: Create two scalable apps with the same name under different domains, no dup endpoint is added into nginx server.conf.
