Installing Kapow!
=================
Kapow! has a reference implementation in Go that is under active development
right now. If you want to start using Kapow! you can choose from several
options.
Download and install a binary
-----------------------------
Binaries for several platforms are available from our
`releases <https://github.com/BBVA/kapow/releases>`_ section, visit the latest
release page and download the binary corresponding to the platfom and
architecture you want to install Kapow! in.
Linux
^^^^^
Install the downloaded binary using the following command as a privileged user.
.. code-block:: bash
$ install -t /usr/local/bin path_to_downloaded_binary
Windows
^^^^^^^
Copy the downloaded binary to a directory of your choice and update the system
PATH variable to include that directory.
Install the package with go get
-------------------------------
If you already have `installed and configured <https://golang.org/cmd/go/>`_
the go runtime in the host where you want to run Kapow!, simply run:
.. code-block:: bash
$ go get -u github.com/BBVA/kapow
Include Kapow! in your container image
--------------------------------------
If you want to include Kapow! in a Docker image you can add the binary directly
from the releases section. Following is an example dockerfile that includes
Kapow!.
.. code-block:: dockerfile
FROM debian:stretch-slim
RUN apt-get update
ADD https://github.com/BBVA/kapow/releases/download/<VERSION>/kapow_linux_amd64 /usr/bin/kapow
RUN chmod 755 /usr/bin/kapow
ENTRYPOINT ["/usr/bin/kapow"]
If the container is intended to run the server and you want to dinamically
configure it, remember to include a --control-bind param with an external bind
address (i.e. 0.0.0.0) and to map all the needed ports in order to get access
to the control interface.
After building the image you can run the container with:
.. code-block:: bash
$ docker run --rm -i -p 8080:8080 -v $(pwd)/whatever.pow:/opt/whatever.pow kapow:latest server /opt/whatever.pow
With the -v parameter we map a local file into the container's filesystem so we
can use it to configure our Kapow! server on startup.
