Feature request.

Please review possibility to save configs in configmap instead of filesystem.
Functionality to disable configs not required in this case.

Looks like service does not disable config files by moving file to <existing_file>.<current_date>.disabled but removes it.

Maybe it is good to make it configurable?

Need to extend documentation with details how to get services from another namespace.
For example application running in namespace "devops-system" need to generate service configs from namespace "bender".

High level description of a task

Need to create application which is listening Kubernetes API and creates bunch of nginx configs based on information in Kubernetes API.

Application should get list of services periodically. Compare this list with list of files saved in target directory.

If service exists in k8s API but does not exist in target directory application should create file with the name <service_name>.conf in target directory.
Template of a file:

location /{{.ServiceName}} {
    proxy_pass http://{{.ServiceFQDN}};
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Scheme $scheme;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Protocol $scheme;
    proxy_set_header X-Forwarded-Proto $scheme;
    # next 3 headers added to support websocket
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

If service not presented in k8s API, but corresponding file exist in target directory, move it to file <existing_file>.<current_date>.disabled

<current_date> should be in format yyyyMMddHHmmss. Example: 20190108113405.

ServiceFQDN is A record for the service <service_name>.<namespace>.svc.cluster.local see https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#services for details.

Need to create

• application itself
• Dockerfile to build image
• kubernetes manifest to start
• short description in README.md
