task-manager 6.2.2

The Task Manager is a server that tracks and dispenses tasks for clients to perform.

The TaskListManager keeps track of lists of tasks that users should support. It has a REST interface to access tasks and update them.

# ln -s /etc/nginx/sites-available/taskmanager /etc/nginx/sites-enabled/taskmanager

Startup scripts

Find out which process management system you are using: # stat /proc/1/exe. If this outputs something along the lines of ‘/lib/systemd/systemd’ skip to the systemd version otherwise you probably are running on an upstart system. See [this StackExchange post](http://unix.stackexchange.com/questions/196166/how-to-find-out-if-a-system-uses-sysv-upstart-or-systemd-initsystem) for more details. Below are configurations for the upstart and systemd provided. (Make sure you should only follow 1 of those).

systemd

There is script that is called from the systemd unit in resources/systemd/taskmanager-run. If you have changed the install location in the first steps please make sure to update this file accordingly.

# cp resources/systemd/taskmanager.service /etc/systemd/system/taskmanager.service
# systemctl enable taskmanager.service
# systemctl start taskmanager
# systemctl restart nginx

upstart

If you have changed the install location in the first steps please make sure to update the upstart file accordingly.

# cp resources/upstart/taskmanager.conf /etc/systemd/system/taskmanager.conf
# initctl reload-configuration
# service taskmanager start
# service nginx restart

You can now reach the taskmanager on port 80 from your network.

Add authentication to the taskmanager (optional)

You can add Basic Authentication to the taskmanager by creating credentials and uncommenting 2 lines from the provided nginx config

# apt install apache2-utils
# htpasswd -c /etc/nginx/.htpasswd username

Uncomment auth_basic ... and auth_basic_user_file ... in the nginx config (/etc/nginx/sites-available/taskmanager).

# systemctl restart nginx

Add sentry.io to the taskmanager

Install the dependencies in the taskmanager virtualenv:

(taskman)$ pip install raven[flask]

Create a drop-in configuration for the systemd unit:

# mkdir /etc/systemd/system/taskmanager.service.d
# touch /etc/systemd/system/taskmanager.service.d/environment.conf
# vim /etc/systemd/system/taskmanager.service.d/environment.conf

Add the following to the file and close it:

[service]
Environment="SENTRY_DSN=YOUR_SENTRY_DSN"

# systemctl daemon-reload
# systemctl restart taskmanager
