command
^^^^^^^
``command`` should reflect CMD in Dockerfile.
If the container is not started with this commande,
the configuration will not be applied.
subcommands
^^^^^^^^^^^
``subcommands`` is a list with some subcommands to handle.
Running container with a matching subcommand run it with setuped ``command``.
.. code:: yaml
subcommands:
- "-*"
- clone
- init
- ls-files
.. pull-quote::
**Note**: Globbing pattern is enabled here.
By default, all args started with hyphen are handled.
user, group
^^^^^^^^^^^
User and group to run the ``command``.
Can be name or uid/gid.
Affect only command handled.
.. code:: yaml
user: 1000
group: root
.. pull-quote::
**Note**: Dockerfile USER value by default.
config_files
^^^^^^^^^^^^
These files should exist (ADD or COPY) and should be jinja templated.
.. code:: yaml
config_files:
- /etc/gitconfig
- .ssh/config.tpl # Will apply to ".ssh/config"
- /tmp/id_rsa: .ssh/id_rsa # Will apply "/tmp/id_rsa" template to ".ssh/id_rsa"
.. pull-quote::
**Note**: if config files end with ".tpl", the extension will be removed.
secret_env
^^^^^^^^^^
These environment variables will be wiped before
running command to keep them secret.
.. code:: yaml
secret_env:
- SSHKEY
- APIKEY
.. pull-quote::
**CAUTION**: if the container is linked to another one,
theses variables will be sent to it anyway.
links
^^^^^
Links are handled here.
Port, name, protocol or environment variables can be used to identify the links.
.. code:: yaml
links:
'ssh': # This is the name to handle link in templates
port: 22
name: 'ssh*'
protocol: tcp
# env can be list, dictionary or string
env:
FOO: bar
# Single doesn't allow multiple links for this ID
# false by default
single: true
# Set to false to get optional link
# true by default
required: true
.. pull-quote::
**Note**: All parameters are optionals.
Raise an error if the link could not be identified.
pre_conf_commands
^^^^^^^^^^^^^^^^^
List of shell commands to run before applying configuration
.. code:: yaml
pre_conf_commands:
- echo something > to_this_file
post_conf_commands
^^^^^^^^^^^^^^^^^^
List of shell commands to run after applying configuration
.. code:: yaml
post_conf_commands:
- echo "something else" > to_this_another_file
clean_env
^^^^^^^^^
Cleanup environment from variables created by linked containers
before running command (True by default)
debug
^^^^^
Print some debug.

.. pyentrypoint documentation master file, created by
sphinx-quickstart on Thu Apr 28 23:51:03 2016.
You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Welcome to pyentrypoint's documentation!
========================================
**pyentrypoint** is a tool written in ``Python`` to manage Docker
containers ``ENTRYPOINT``.
This tool avoids writing shell scripts to:
- Handle commands and sub commands
- Identify linked containers
- Auto configure container using `jinja2` templates
- Run commands before starting service
- Clean environment before running service
- Increase security by setuid/setgid service

Installation
============
All you need to do is to setup a ``yaml`` file called
``entrypoint-config.yml`` and to install **pyentrypoint** in your
``Dockerfile`` using pip.
.. code:: dockerfile
FROM debian
# Installing git for example
RUN apt-get update && apt-get install git python-pip -y
# Install pyentrypoint
RUN pip install pyentrypoint
# Copy config file in the current WORKDIR
COPY entrypoint-config.yml .
# Set ENTRYPOINT
ENTRYPOINT ['pyentrypoint']
# git will be the default command
CMD ['git']
.. code:: dockerfile
FROM alpine
# Installing git for example
RUN apk add --update py-pip git
# Install pyentrypoint
RUN pip install pyentrypoint
# Copy config file in the current WORKDIR
COPY entrypoint-config.yml .
# Set ENTRYPOINT
ENTRYPOINT ['pyentrypoint']
# git will be the default command

Templates
=========
You can generate configuration for your service with jinga2 template.
Here is an example for an hypothetical ssh config file:
.. code:: jinja
host server:
hostname {{links.ssh.ip}}
port {{links.ssh.port}}
Templates will be replaced with ip address and port of the identified
link. All links can be accessed from ``links.all``, this is a tuple of
links you can iterate on it.
.. code:: jinja
{% for link in links.all %}
host {{link.names[0]}}
hostname {{link.ip}}
port {{links.port}}
{% endfor %}
If you change the option ``single`` to ``false`` in the
``entrypoint-config.yml``, the identified link ``ssh`` will become a
tuple of links. You must iterate on it in the ``jinja`` template.
.. code:: jinja
{% for link in links.ssh %}
host {{link.names[0]}}
hostname {{link.ip}}
port {{links.port}}
{% endfor %}
Accessing environment in template.
.. code:: jinja
{% if 'SSHKEY in env' %}
{{env['SSHKEY']}}
{% endfor %}
Accessible objects
~~~~~~~~~~~~~~~~~~
You have 4 available objects in your templates.
- ``config``
- ``links``
- ``containers``
- ``environ``
config
^^^^^^
``Config`` reflect the config file. You can retrieve any setup in this
object.
(see ``config.py``)
links
^^^^^
``Links`` handles ``Link`` objects. You can identify links using
wildcard patterns in the configuration file.
``link`` is related to one physical link (one ip and one port).
``link`` handles the following attributes: - ``ip`` - link ip - ``port``
- link port (integer) - ``environ`` - related container environment -
``protocol`` - link protocol (``tcp`` or ``udp``) - ``uri`` - link URI
(example: ``tcp://10.0.0.3:80``) - ``names`` - tuple of related
container names
containers
^^^^^^^^^^
``containers`` handles a tuple of ``container`` object.
``container`` handles the following attributes: - ``ip`` - container ip
- ``environ`` - container environment - ``names`` - List of containers
names - Names are sorted by length, but container ID will be the last
element. - ``id`` - Hexadecimal container ID (if available, empty string
else) - ``links`` - Tuple of ``link`` objects related to this container
environ
^^^^^^^
``environ`` is the environment of the container (os.environ).
``env`` is an alias to ``environ``.
