KUISP - Kubernetes UI & Service Proxy

KUISP (pronounced "kwisp") is a utility to simplify the
serving of static HTML/JavaScript UIs, backed by possibly
multiple RESTful API services. KUISP does the following:

  • serve static content from the speicified directory
  • use Golang templates
    to create configuration files from specified templates &
    environment variables
  • sets up reverse proxies to the specified services
  • http/2 server if TLS certificate/key is specified
  • configurable CA certificates for remote TLS services

The benefit this brings is that browser clients only need network
access to the UI server, not the actual API servers.


Usage of kuisp:
  -l, --access-logging=false: Enable access logging
      --ca-cert=[]: CA certs used to verify proxied server certificates
      --compress=false: Enable gzip/deflate response compression
  -c, --config-file=[]: The configuration files to create in the form "<template>=<output>"
  -d, --default-page="": Default page to send if page not found
      --max-age=0: Set the Cache-Control header for static content with the max-age set to this value, e.g. 24h. Must confirm to
  -p, --port=80: The port to listen on
  -s, --service=[]: The Kubernetes services to proxy to in the form "<prefix>=<serviceUrl>"
      --skip-cert-validation=false: Skip remote certificate validation - dangerous!
      --tls-cert="": Certificate file to use to serve using TLS
      --tls-key="": Certificate file to use to serve using TLS
  -w, --www=".": Directory to serve static files from
      --www-prefix="/": Prefix to serve static files on

Service proxying

For each service that you want to reverse proxy to, you can specify the -s or --service
flag. The input to the flag must be in the format prefix=serviceUrl, e.g.

-s /db/=http://influxdb:8086/db/ -s /api/=http://apiserver:8080/api/v2/

As you can see you can specify the flag multiple times. You can also use environment
variable expansion such as:


Note the use of single quotes to ensure the environment variables don't get expanded
in your shell before being passed to KUISP.

Configuration file templates

KUISP can process Golang templates into
configuration files. KUISP can process multiple templates into multiple configuration
files using the -c or --config-file flags. The configuration files & templates are specified in a similar fashion to the
service definitions:

-c config.json.tmpl=config.json -c myconfig.ini.tmpl=/etc/myconfig.ini

Note that you can use relative or absolute paths for both templates & output files. Again,
you can use environment variable expansion for any values:


The only variables that are available in the template for
processing are environment variables & are accessed like this:

{{ .Env.ENV_VAR_1 }}

As an example, the following template:

  "value": "{{ .Env.MY_VALUE }}"

When run with the environment variable MY_VALUE set to 3, would output:

  "value": "3"


Just run make.
