=====================
 SSL endpoints check
=====================

Utility for checking if all of the ports exposed outside of Kubernetes cluster
use SSL tunnels.

Prerequisites
-------------

Configuration
~~~~~~~~~~~~~

``-kubeconfig``
  Optional unless ``$HOME`` is not set. Defaults to ``$HOME/.kube/config``.

Build (local)
~~~~~~~~~~~~~

- go_ (1.11+, tested on 1.13)

.. _go: https://golang.org/doc/install

Build (Docker)
~~~~~~~~~~~~~~

- Docker_ engine
- make (optional)

.. _Docker: https://docs.docker.com/install

Test
~~~~

- Ginkgo_
- GolangCI-Lint_ (optional)

.. _Ginkgo: https://onsi.github.io/ginkgo/#getting-ginkgo
.. _GolangCI-Lint: https://github.com/golangci/golangci-lint#install

Building
--------

Command (local)
~~~~~~~~~~~~~~~

.. code-block:: shell

    $ mkdir bin
    $ go build -o bin/sslendpoints

Additional ``bin`` directory and specifying ``go build`` output are used to
declutter project and maintain compatibility with Docker-based process. Running
``go build`` without parameters will create ``sslendpoints`` binary in current
directory.

Command (Docker)
~~~~~~~~~~~~~~~~

.. code-block:: shell

    $ make # or commands from corresponding "make" targets


Running
-------

Command (local)
~~~~~~~~~~~~~~~

.. code-block:: shell

    $ bin/sslendpoints [-kubeconfig KUBECONFIG]

Command (Docker)
~~~~~~~~~~~~~~~~

.. code-block:: shell

    $ docker run --rm --volume $KUBECONFIG:/.kube/config \
        sslendpoints-build-img /bin/sslendpoints

    $ docker run --rm --volume $KUBECONFIG:/opt/config \
        sslendpoints-build-img /bin/sslendpoints -kubeconfig /opt/config

Output
~~~~~~


Testing
-------

.. code-block:: shell

    $ go test ./...     # basic
    $ ginkgo -r         # pretty
    $ golangci-lint run # linters
