sysplan 0.0.1.dev45

CLI configuration

sysplan automates host configuration and requires root privilege. If you install sysplan with pip install --user then you will need to run

Optionnal: install pygments for syntax highilightning.

Host configuration

sysplan will parse /etc/sysplan.d/*.yaml for configuration and execute python or shell plugins.

You can dump the configuration with: sysplan conf.

YAML schema

The basic structure of the yaml configuration is like this:

plugin_name:
  your-first-plan-name:
    any: config
    for:
    - your plan

Examples

The sysplan.d.example directory of the git repository contains reference implementations which you can copy at will.

Testing

You may use the example configuration for testing by exporting the SYSPLAN_D env var:

export SYSPLAN_D=/path/to/git/clone/sysplan.d.example

The SYSPLAN_ROOT env var is nice to make sure sysplan won’t write your host:

export SYSPLAN_ROOT=/tmp/test-sysplan-1

You may then use the example configuration, examples:

.. code-block:: shell

sudo -sE sysplan conf sudo -sE sysplan diff sudo -sE sysplan test sudo -sE sysplan apply sudo -sE sysplan destroy

Basics and systemd

Try adding the following content into /etc/sysplan.d/example_systemd.yaml:

services:
  sysplan-test-service:
    TEST_ENV_VAR: 2
    Unit:
      Description: Example Service
    Service:
      Type: oneshot
      ExecStart: /bin/bash -c 'echo nice!'
      WorkingDirectory: /tmp

timers:
  sysplan-test-service:
    Timer:
      OnCalendar: '*-*-* 23:00:00'

mounts:
  mnt-backups:
    Unit:
      Description: Mount NFS Share
    Mount:
      What: 172.24.0.5:/srv/backups
      Where: /mnt/backups
      Type: nfs
      Options: defaults
      TimeoutSec: 10
    Install:
      WantedBy: multi-user.target

Then, try the following commands:

• sysplan diff

• sysplan apply

• sysplan destroy

• sysplan help

Custom bash modules

Add the following to /etc/sysplan.d/bash_example.yaml:

bash_example.sh:
  plan-one:
    somevar: date
    nested:
    - item: /tmp/$plan_name

  plan-two:
    somevar: uname -a

Add the following to /etc/sysplan.d/bash_example.sh:

write() {
    $somevar > /tmp/$plan_name
    cat /tmp/$plan_name
}

diff() {
    if [ ! -f $nested_0_item ]; then
        echo + $nested_0_item TO CREATE
    else
        $somevar | $(which diff) -u $nested_0_item -
    fi
}

activate() {
    echo activated >> /tmp/$plan_name
}

destroy() {
    rm -rf /tmp/$plan_name
}

Then again, play with the sysplan commands.

files

You can also have files as such:

files:
  /etc/profile.d/pipuser.sh:
    mode: '0755'
    owner: root
    group: root
    content: |
      export PATH=$HOME/.local/bin:$PATH

docker & docker_compose

Docker has a special plan generation because of the variety of resources it has to offer, example configuration:

docker:
  networks:
    web:
    test:

  volumes:
    test:
